Terms of Service

Last updated: April 24, 2026 · Effective: April 24, 2026

Summary for humans

Not part of the contract · for orientation only

Tariffs API is an informational tariff-data service operated by Brightworks Digital Pte. Ltd., a Singapore company. We publish HTS lookups, a duty calculator, rate-change alerts (HTS Watch), and a developer API, all built on public US government data from USITC, USTR, CBP, and the Federal Register.

We are not a licensed customs broker. We don't classify your goods for you, we don't file entries, and we don't bind CBP to anything. Final classification and duty determinations are made by CBP. Before you file, verify with a licensed customs broker or request a CBP ruling.

Some of our content; product enrichment summaries describing what an HTS code covers; is generated with the help of AI models and can contain mistakes. The AI is used to describe codes and verify our deterministic rate parser. It does not classify your products. Check the underlying source before you act on a rate, and verify classification with a licensed customs broker.

Paid subscriptions auto-renew until you cancel. Cancellation takes effect at the end of the current billing period. EU and UK consumers have a 14-day cooling-off right, subject to the usual exception where you ask us to start API access immediately.

If something goes wrong, our total liability to you is capped at the greater of what you paid us in the prior 12 months or USD 100 — except where law prevents us from capping it.

Disputes go to arbitration (AAA in the US for consumers, SIAC for businesses worldwide), governed by Singapore law. The binding version of all of this is in the sections below.

Parties and company information

These Terms of Service (the "Terms") are a legally binding agreement between you (the "Customer" or "you") and Brightworks Digital Pte. Ltd., a Singapore private limited company (UEN 202504662W), having its registered office at 2 Venture Drive, #19-21, Vision Exchange, Singapore 608526 ("Brightworks", "Tariffs API", "we", "us", or "our").

By creating an account, accessing the Service, or sending any request to our API, you agree to these Terms, our Privacy Policy, and any tier-specific terms referenced at the time of purchase.

1. Definitions

In these Terms, capitalized terms have the meanings set out below.

  • "Service" means the Tariffs API web application at tariffsapi.com and any subdomains, the duty calculator, the HTS Watch alert product, the developer API, and any related tools, documentation, and communications provided by Brightworks.
  • "Customer" means any individual or legal entity that accesses the Service, whether on a free tier or a paid plan.
  • "Content" means any text, data, code, comments, or other material displayed by or transmitted through the Service.
  • "Data" means the tariff schedule, rate, classification, country-of-origin, and related trade-measure information made available through the Service.
  • "API" means the programmatic HTTP interface described at /api-documentation, including any authentication, rate-limiting, and error-handling behavior documented there.
  • "Tariff Information" means the structured rate data, HTS classifications, Chapter 99 measure indicators, and other outputs of the Service. Tariff Information is an informational product; see Section 3.
  • "Customer Data" means information you submit to the Service, including HTS Watch lists, saved searches, origin-country preferences, and API request patterns associated with your account.

2. Acceptance of these Terms and your account

You create an account by registering at tariffsapi.com with a valid email address, or by accepting an invitation from an existing Customer. You may also create an account indirectly when you pay for a plan through our checkout. Creating, accessing, or continuing to use an account constitutes acceptance of these Terms.

You must be at least 18 years old and have the legal capacity to enter into a binding contract. If you are registering on behalf of a business, you represent that you are authorized to bind that business, in which case "you" refers to both you individually and the business you represent.

You agree to provide accurate, current, and complete registration information and to keep it up to date. You are responsible for all activity that occurs under your account, including all usage of API keys issued to your account (see Section 7). You must notify us at security@tariffsapi.com as soon as you become aware of any unauthorized use.

3. Nature of the Service — informational only

Tariffs API is an informational data service. It is not a customs broker and does not give classification advice, issue binding determinations, or file customs entries.

The Service provides structured access to publicly available US tariff information sourced from the US International Trade Commission (USITC), the Office of the US Trade Representative (USTR), US Customs and Border Protection (CBP), and the Federal Register. We transform and index that information; we do not originate it and we do not verify it line-by-line.

Brightworks Digital Pte. Ltd. is not a customs broker licensed under 19 CFR Part 111 and does not hold itself out as one. We do not:

  • provide customs classification advice;
  • issue binding tariff rulings;
  • file entries, declarations, post-summary corrections, or CAPE claims with CBP;
  • act as your agent before CBP, the Court of International Trade, or any other authority; or
  • guarantee that any rate displayed on the Service will be the rate CBP assesses on your entries.

You — the Customer and the importer of record for your shipments — remain solely responsible for final HTS classification, country-of-origin determinations, valuation, and the duties you pay. Those determinations are made by CBP.

For binding determinations, consult a licensed customs broker or request a ruling letter from CBP under 19 CFR Part 177. We can help you find information; we cannot substitute for a professional advisor.

4. Data accuracy and limitations

4.1 Sources and sync schedule

Tariff Information is derived from official government publications including the Harmonized Tariff Schedule of the United States, USTR Federal Register notices, CBP CSMS messages, and related primary sources. Data is synchronized on the schedule published at /status; that schedule may change without notice.

4.2 No warranty of accuracy, completeness, or timeliness

Tariff rates, classifications, and trade measures change frequently — sometimes between the issuance of a Federal Register notice and its effective date. We make no representation or warranty that:

  • the Data is accurate or complete at any given moment;
  • the Service reflects any regulatory change within a specific time window;
  • historical data displayed on the Service captures every intervening change; or
  • the rate shown for any HTS code will be the rate CBP applies to a particular entry.

You should independently verify any rate with the official source before relying on it for a customs entry, a pricing decision, a contract, or any other financial decision. The "official" source for a given field is identified in the Service's data-source documentation at /api-documentation#data-sourcing.

4.3 Automated and AI-assisted fields

Certain fields on the Service are produced with the assistance of automated tools, including large language models ("AI-assisted fields"). These currently include, without limitation:

  • product enrichment summaries (descriptions of what an HTS code covers, example goods, related schedule codes) shown on HTS code pages;
  • AI-assisted verification of our deterministic rate parser (cross-checking parsed duty values against the raw source text); and
  • other fields labelled as "AI-assisted", "automated", or similar in the Service UI or API response metadata.

AI-assisted fields may contain parsing, classification, or summarization errors. They are intended as a starting point for research, not as a determinative answer. Where an AI-assisted field conflicts with the underlying primary source, the primary source controls — and we will correct AI-assisted outputs as we identify errors.

4.4 Your obligation to verify

You agree that before using any Tariff Information to make a customs filing, pricing decision, contractual commitment, or other business-critical action, you will independently verify the relevant data against the underlying government source or with a licensed customs broker. You acknowledge that the Service is not a substitute for that verification.

5. Acceptable use

5.1 Permitted uses

You may use the Service to:

  • look up, calculate, and research tariff rates for your own importing, exporting, sourcing, or compliance operations;
  • integrate the API into your own internal tools, back-office workflows, ERP systems, or customer-facing applications (including resale of tariff-aware software) subject to the restrictions in Section 5.2;
  • publish derived analysis — articles, dashboards, newsletters, product content — that draws on Tariff Information, provided you attribute the underlying government source (e.g. "Data: USITC HTS 2026 Revision") and do not redistribute the Service's raw tariff dataset; and
  • cache API responses as reasonably necessary to operate your application, subject to the rate-limit and SLA terms at /api-documentation.

5.2 Prohibited uses

You may not, and must not permit any third party to:

  • redistribute, resell, or otherwise make available the raw Tariff Information as a competing tariff dataset, data feed, or API product;
  • scrape, crawl, or otherwise programmatically access the Service outside of the documented API and the published per-plan rate limits;
  • reverse engineer, decompile, or attempt to derive the source code, algorithms, or underlying data processing techniques of the Service, except to the minimum extent permitted by mandatory applicable law;
  • use the Service, or any Tariff Information obtained from the Service, to provide unlicensed customs brokerage services to third parties in any jurisdiction where such services require a license (including under 19 CFR Part 111 in the United States);
  • upload or transmit to the Service any content that is unlawful, infringing, malicious, or that you do not have the right to submit;
  • attempt to interfere with the Service's integrity, security, or availability (including by probing, bypassing authentication, or running denial-of-service testing without our prior written consent); or
  • use the Service in violation of US, Singapore, or other applicable export control, sanctions, or trade laws.

5.3 Enforcement

We may investigate suspected violations of this Section 5 and, at our discretion, warn you, throttle or suspend the relevant API keys, suspend the account, or terminate under Section 12. Where a violation exposes us or another Customer to legal risk, we may act without prior notice.

6. Subscriptions, billing, and cancellation

6.1 Pricing and plans

Prices, plan inclusions, and rate limits are those displayed at /pricing at the time you complete your purchase. By completing checkout you agree to the price, the billing frequency, and the tier-specific limits shown on that page.

6.2 Free trial

Where a free trial is offered, its duration and conditions are stated on /pricing. For plans marketed as "no credit card required to start", no payment method is needed to begin the trial. Other plans may require a payment method at the start of the trial; we will disclose this before you are asked to pay. Trials convert to paid subscriptions automatically at the end of the trial period unless cancelled.

6.3 Auto-renewal

Monthly subscriptions renew every month on the anniversary of your sign-up (or, for annual plans, every year) at the then-current rate for the plan, using the payment method on file. We will send a renewal reminder before each renewal to the email on file where required by applicable law (including, where applicable, California Business and Professions Code § 17602 and New York General Business Law § 527-a).

6.4 Cancellation

You may cancel your subscription at any time from the account settings (/api_keys/billing_portal) or by emailing billing@tariffsapi.com. Cancellation takes effect at the end of the current billing period — you retain access to paid features until that date, and you are not charged for the next period. Except where required by mandatory consumer law, we do not issue pro-rated refunds for partially used billing periods.

6.5 Cooling-off for EU and UK consumers

If you are a consumer resident in the European Union or the United Kingdom, you have a statutory right under Directive 2011/83/EU (as transposed) and the UK Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 to cancel this contract within 14 days after it is concluded, without giving a reason. To exercise this right, email billing@tariffsapi.com with an unambiguous statement that you are cancelling.

Exception for digital services commenced at your request. If you expressly request that API access or other Service functionality begin during the 14-day cooling-off period and acknowledge that you lose your right to cancel once performance has fully begun, you will not be entitled to a refund for Service actually delivered. This is the standard exception under Article 16(m) of Directive 2011/83/EU. We will display this acknowledgement at checkout for the relevant plans.

6.6 Taxes

Prices displayed are exclusive of any applicable sales tax, VAT, GST, or equivalent indirect tax, unless expressly stated otherwise. Where we are required to collect such tax (including Singapore GST, EU VAT via OSS, or US state sales tax in jurisdictions where we have a tax obligation), we will add it to your invoice.

6.7 Failed payments

If a renewal payment fails, we may retry the charge and, after a reasonable grace period, suspend or downgrade paid features until payment is received. You remain liable for the fees accrued up to the point of suspension or cancellation.

7. API-specific terms

7.1 Rate limits

Per-minute and per-day rate limits, burst allowances, and maximum concurrent connections are those published at /api-documentation for your plan tier. Requests in excess of those limits may be rejected with a 429 status code. Repeated or sustained excess may result in key throttling, key revocation, or account suspension under Section 5.3.

7.2 API keys

API keys identify your account for the purpose of billing and rate limiting. You are responsible for keeping your keys confidential, rotating them if compromise is suspected, and revoking keys promptly via the account UI. You are liable for all usage accruing to a key until the key is revoked through the account UI, including usage by third parties (including your employees, contractors, and any unauthorized party) who gain access to the key. If you believe a key has been compromised, revoke it immediately and email security@tariffsapi.com.

7.3 SLA

The free tier is provided without any service level commitment. Paid plans may include a service level agreement (uptime target, credit mechanism); the applicable terms are those stated in the SLA document linked from your plan on /pricing and in the API documentation at the time of purchase. Service credits are the sole and exclusive remedy for availability shortfalls and are subject to the liability cap in Section 9.

7.4 Changes to the API

We may evolve the API over time. Breaking changes will be versioned; we will maintain a deprecated API version for a reasonable transition period documented in the changelog at /changelog. Non-breaking changes (new fields, new endpoints, performance improvements) may be shipped without notice.

8. Customer data and privacy

8.1 What we collect

Our collection, use, and disclosure of Customer Data and other personal information is described in our Privacy Policy, which is incorporated by reference.

8.2 Ownership of Customer Data

As between you and us, you retain all rights in your Customer Data, including your HTS Watch lists, saved searches, and the content of your API requests. You grant us a limited, worldwide, non-exclusive, royalty-free licence to process Customer Data solely to the extent necessary to provide and secure the Service, to comply with our legal obligations, and as described in the Privacy Policy.

8.3 Aggregate analytics

We may compile aggregated, de-identified usage analytics — for example, the popularity of particular HTS chapters, the geographic distribution of lookups, or the performance characteristics of API endpoints — to operate and improve the Service, plan capacity, and publish product research. Aggregated analytics do not identify you or any of your end users, and we do not sell Customer-identifiable data to advertisers, data brokers, or other third parties. See the Privacy Policy for detail.

8.4 Security

We use commercially reasonable administrative, technical, and physical safeguards to protect Customer Data, including encryption in transit and at rest for data stores that support it, access controls, and routine patching of dependencies. No method of electronic storage or transmission is perfectly secure; we do not warrant that the Service is immune to unauthorized access. We will notify affected Customers of a personal-data breach as required by applicable law (Singapore PDPA, GDPR, etc.).

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL AGGREGATE LIABILITY OF BRIGHTWORKS DIGITAL PTE. LTD. AND ITS OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, SUPPLIERS, AND AFFILIATES, ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR YOUR USE OF THE SERVICE, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), MISREPRESENTATION, STATUTE, OR OTHERWISE, IS CAPPED AT THE GREATER OF (a) THE FEES YOU ACTUALLY PAID TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (b) ONE HUNDRED US DOLLARS (USD 100).

To the maximum extent permitted by applicable law, neither party will be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any:

  • lost profits, lost revenue, lost savings, or lost business opportunity;
  • loss or corruption of data;
  • loss of goodwill or reputation;
  • customs duties, penalties, interest, or fines assessed by any customs authority against you or a third party;
  • costs of procurement of substitute services; or
  • amounts owed by you to any third party, including your customers or suppliers,

even if we have been advised of the possibility of such damages.

9.1 Non-waivable liabilities

The limitations and exclusions in this Section 9 do not apply to:

  • liability that cannot be limited or excluded under applicable law (for example, death or personal injury caused by negligence, fraud, or fraudulent misrepresentation);
  • liability for gross negligence or wilful misconduct where mandatory law prevents its limitation; or
  • rights of EU, UK, or other consumers that cannot be waived under the consumer protection law of their jurisdiction of residence.

9.2 Allocation of risk

You acknowledge that the pricing of the Service reflects the allocation of risk set out in this Section 9, that this allocation is an essential basis of the bargain between you and us, and that the Service would not be provided at the stated price without it.

10. Indemnification

You will defend, indemnify, and hold harmless Brightworks Digital Pte. Ltd. and its officers, directors, employees, contractors, suppliers, and affiliates from and against any third-party claim, action, proceeding, liability, damage, loss, settlement, penalty, or reasonable expense (including reasonable attorneys' fees) arising out of or relating to:

  • your use of Tariff Information or the API to provide customs brokerage or other licensed services to a third party without holding the licence required in the relevant jurisdiction;
  • your violation of the Acceptable Use terms in Section 5, including any redistribution of raw Tariff Information as a competing dataset;
  • your breach of these Terms or the Privacy Policy;
  • Customer Data you submit to the Service, where that data infringes a third party's rights or violates applicable law; or
  • your negligent or wilful misconduct in connection with the Service.

We will give you prompt notice of any claim for which we seek indemnity, allow you to control the defence (with counsel reasonably acceptable to us), and reasonably cooperate at your expense. You may not settle any claim that imposes a non-monetary obligation on us, or that does not unconditionally release us, without our prior written consent.

11. Intellectual property

11.1 Our IP

The Service — including its UI, schemas, data models, parsers, classifiers, documentation, API design, and brand — is the proprietary property of Brightworks Digital Pte. Ltd. and its licensors, protected by copyright, trademark, database right, and trade secret law. These Terms grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the Service as permitted in Section 5; no other rights are granted, whether by implication, estoppel, or otherwise.

11.2 Underlying government data

The underlying US tariff schedule, Federal Register text, and CBP-issued measure text are works of the US federal government and are not subject to copyright protection in the United States (17 U.S.C. § 105). Our organization, indexing, labelling, enrichment, and presentation of that underlying data are protected under Section 11.1; the underlying data itself is not.

11.3 Your IP

You retain ownership of any content you submit to the Service (such as your HTS Watch lists, saved queries, and API request bodies). The licence you grant us for that content is described in Section 8.2 and the Privacy Policy.

11.4 Feedback

If you send us feedback, bug reports, or feature suggestions, you grant us a perpetual, irrevocable, royalty-free, worldwide licence to use that feedback to improve the Service. You are not obliged to send feedback, and we are not obliged to act on it.

12. Termination

12.1 Termination for convenience

Either party may terminate these Terms for convenience on thirty (30) days' written notice (which, for this purpose, includes cancellation via the in-product UI or email). If you terminate mid-billing-cycle, access continues through the end of the current period under Section 6.4.

12.2 Termination for breach

We may suspend or terminate these Terms and your access to the Service immediately, with written notice, if you materially breach these Terms and, for breaches capable of cure, fail to cure within fifteen (15) days of notice (or such shorter period as may be necessary to prevent ongoing harm to us, another Customer, or a third party).

12.3 Effect of termination

On termination: (a) your right to access the Service ends; (b) API keys are revoked; (c) we may delete Customer Data in accordance with the retention schedule in the Privacy Policy; and (d) sections that by their nature should survive termination (including Sections 3, 4, 5.2, 8–11, 13, 14, and 15) survive.

13. Governing law and dispute resolution

13.1 Governing law

These Terms, and any non-contractual obligations arising out of or in connection with them, are governed by and construed in accordance with the laws of the Republic of Singapore, without regard to conflict-of-laws principles. This choice of law is subject to any mandatory consumer protection rights you have in your jurisdiction of residence.

13.2 Informal resolution

Before filing any arbitration or court claim, you agree to send written notice of the dispute to legal@tariffsapi.com describing the claim and the relief you seek, and to negotiate in good faith for thirty (30) days.

13.3 Arbitration — US consumers

If you are a consumer resident in the United States, any dispute that cannot be resolved informally will be resolved by binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules, or, at your election, by JAMS under its Streamlined Arbitration Rules. Arbitration will take place remotely, or in the federal judicial district where you reside if remote proceedings are not available. Judgment on the award may be entered in any court of competent jurisdiction.

Nothing in Section 13.3 prevents you from filing a small-claims action in your jurisdiction of residence if the claim qualifies and you proceed on an individual basis.

13.4 Arbitration — business-to-business and non-US users

Any dispute not covered by Section 13.3 will be finally resolved by arbitration administered by the Singapore International Arbitration Centre ("SIAC") under the SIAC Rules then in force. The seat of the arbitration is Singapore. The language of the arbitration is English. The tribunal consists of one arbitrator unless the amount in dispute exceeds USD 500,000, in which case the tribunal consists of three arbitrators.

13.5 Class action waiver

To the maximum extent permitted by applicable law, disputes will be resolved on an individual basis. Neither party may bring a claim as a plaintiff or class member in a class, consolidated, or representative action. If this class action waiver is held unenforceable in a particular jurisdiction, the arbitration agreement in Sections 13.3 or 13.4 (as applicable) will be unenforceable in that jurisdiction but remain enforceable elsewhere.

13.6 Equitable relief

Either party may seek injunctive or other equitable relief in a court of competent jurisdiction to protect intellectual property rights, confidential information, or to enforce the Acceptable Use terms, notwithstanding the arbitration obligations above.

14. Changes to these Terms

We may update these Terms from time to time. If we make a material change, we will notify you by email at the address on file and by an in-app banner no less than thirty (30) days before the change takes effect. The "Last updated" date at the top of this page reflects the most recent revision.

If you do not agree with a change, you may cancel your account before the change takes effect under Section 6.4. Your continued use of the Service after the effective date of the change constitutes acceptance of the revised Terms.

Changes to arbitration or governing-law provisions (Section 13) apply only to disputes arising after the effective date of the change; disputes that have already accrued remain governed by the version of Section 13 in force when they accrued.

15. Miscellaneous

15.1 Entire agreement

These Terms, together with the Privacy Policy, any SLA referenced at purchase, and any written order form executed between us, constitute the entire agreement between you and us concerning the Service, and supersede any prior or contemporaneous agreements on the same subject.

15.2 Severability

If any provision of these Terms is held invalid or unenforceable, the remaining provisions will remain in full force and effect; the invalid provision will be interpreted to best accomplish its original intent within the limits of applicable law.

15.3 No waiver

A failure or delay in exercising any right under these Terms is not a waiver of that right. Any waiver must be in writing to be effective.

15.4 Order of precedence

In the event of a conflict between the "Summary for humans" at the top of this page and the binding terms below, the binding terms control. In the event of a conflict between these Terms and any written order form between you and us, the order form controls to the extent of the conflict.

15.5 Assignment

You may not assign these Terms or any rights or obligations under them without our prior written consent, except to a successor in a merger, acquisition, or sale of substantially all of your assets, provided that the successor assumes all obligations under these Terms. We may assign these Terms without your consent to an affiliate or to a successor in a merger, acquisition, reorganisation, or sale of substantially all our assets.

15.6 Force majeure

Neither party is liable for any failure or delay in performance (other than payment obligations) caused by events beyond its reasonable control, including acts of God, natural disasters, war, terrorism, labour disturbances, internet or telecommunications failures, government action, or failures of third-party infrastructure providers.

15.7 Notices

We may send notices to you by email at the address on file or by in-product notification. You must send notices to us at legal@tariffsapi.com, with a courtesy copy by post to the registered office address in the preamble for notices relating to disputes, termination, or legal process.

15.8 Independent contractors

These Terms do not create a partnership, joint venture, agency, employment, or fiduciary relationship between you and us.

15.9 Third-party rights

A person who is not a party to these Terms has no right under the Contracts (Rights of Third Parties) Act 2001 of Singapore or any equivalent statute to enforce any term of these Terms, except that our officers, directors, employees, contractors, suppliers, and affiliates may enforce the limitation of liability in Section 9 and the indemnity in Section 10.
