Tariffs API vs Passport.
Passport is a full cross-border platform for DTC brands. Tariffs API is just the duty calculation, exposed as a clean REST endpoint.
Passport (passportglobal.com) serves 1,300+ DTC brands with an end-to-end cross-border stack: shipping, compliance, localization, fulfillment, and tariff updates. If you're a mid-market or enterprise brand running international fulfillment, they're a known quantity. If you just need the duty number to show landed cost at checkout, you don't need their whole platform.

When Passport is the right pick

- →You want 3PL, TMS, and WMS integrations baked in alongside duty calculation.
- →You have a team and a budget to run a vendor evaluation and onboarding process.
When Tariffs API is the right pick
- ✓You need the duty rate at checkout — not a full international fulfillment platform.
- ✓You'd rather call a REST endpoint than connect to a 3PL/TMS/WMS suite.
- ✓You want to evaluate the product on the docs page, not on a demo call.
- ✓You're shipping a feature, not migrating a fulfillment stack.

Can I use Tariffs API alongside Passport?
Yes. If you already use Passport for shipping and fulfillment, you can still hit Tariffs API directly for duty calculations at quote, cart, or pre-checkout — useful for marketplaces, ERPs, or quoting tools where you need the rate before a shipment is created.
Does Tariffs API ship the package?
No. We don't ship, label, classify, or file customs entries. We return duty rates. For shipping and fulfillment, use a carrier or platform like Passport, Zonos, or Easyship.
Is Tariffs API cheaper than Passport?
Passport doesn't publish pricing, so a head-to-head dollar comparison isn't possible. We publish $199/month flat, 100,000 API calls included, no contract. Cancel any time.
