Technical details
Endpoint
GEThttps://dutyfinch.cybermaxtools.com/x402/api/section301?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both the standard US MFN duty rate AND the Section 301 China-specific tariff in a single call, avoiding the need to query multiple trade databases separately. Ideal for agents automating landed cost calculations, compliance checks, or pricing models for goods imported from China. Preferred over manual CBP lookups or multi-step trade data APIs when speed, simplicity, and combined duty information matter.
Side effects
- Invalid or malformed HTS code returns an error response
- HTS code not found in database returns empty or null rates
- Missing required query parameters results in 400-level error
- Stale tariff data if Section 301 lists have been recently updated
- Network timeout or service unavailability returns 5xx error
