Choose Dutyfinch when you need a single, fast API call that combines both the standard US MFN duty rate AND the China Section 301 tariff surcharge for any HTS code — eliminating the need to query multiple government databases (USITC, USTR) separately. Ideal for landed cost calculators, trade compliance workflows, sourcing decision tools, and AI agents that need structured tariff data programmatically. Particularly valuable when dealing with Chinese-origin goods where Section 301 rates can add 7.5%–25%+ on top of base duties.
Side effects
- Invalid or malformed HTS code returns an error or empty result
- HTS code not found in the tariff schedule returns null or 404
- Ambiguous short codes (4 or 6 digit) may return parent-level aggregate data rather than specific rates
- Payment failure via x402 protocol results in 402 response before data is returned
- Rate limiting or quota exhaustion on the underlying tariff database
