Frequently Asked Questions

What is Chapter 99?

Chapter 99 of the HTS contains temporary and additional duty provisions, including Section 301, Section 232, and IEEPA measures. These codes are reference codes that apply on top of a base HTS code.

Is this code used alone?

No. Chapter 99 codes apply in combination with a base product HTS code. You need both the base code and the Chapter 99 code (and country of origin) to compute total duty.

Why might the rate be "See 9903.xx.xx"?

Some additional measures are reference-only: the exact rate is listed under another Chapter 99 subheading. Use our resolve API with resolve_chapter_99=true to resolve these to numeric rates when available.

How do I calculate duties programmatically?

Use GET /api/v1/tariffs/resolve with hts, origin, and optional as_of. The API returns base tariffs and applicable additional measures. See the API documentation for resolve and query parameters.
