How this service works
Current US import duty rate for any HTS code (entityId like 'hts:6109.10.00'): the base (MFN) rate AND an estimated combined effective rate including Chapter-99 Section 301/232/IEEPA add-ons — the landed-duty answer a supply-chain agent needs. The combined figure is a labeled estimate and excludes product/country exclusions. Or 'hts:release' for the current HTS revision.
Output
Returns a JSON object containing the HTS entity details including the base MFN duty rate, a labeled estimate of the combined effective rate (base plus applicable Chapter-99 Section 301, Section 232, and IEEPA surcharges), and the HTS line metadata. Note: the combined figure is an estimate and excludes product- or country-specific exclusions. When queried for 'hts:release', returns the current HTS revision information.
Example use cases
Example prompt
“What is the current base MFN duty rate and estimated combined effective tariff rate — including any Section 301, 232, or IEEPA add-ons — for HTS code 6109.10.00?”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/tariffwatch/statusWhen to prefer
Use this endpoint when you need the current US import duty rate — both the base MFN rate and the estimated total effective rate including Section 301 (China), Section 232 (steel/aluminum), and IEEPA add-ons — for a specific HTS tariff line. Prefer this over general trade databases when you need a combined effective rate estimate in a single API call. Best suited for compliance tools, import cost calculators, product pricing models, and trade intelligence applications that need current US tariff data per HTS code.
Side effects
- Invalid or unrecognized HTS code returns an error or empty result
- HTS code not tracked by the service returns no entity data
- Omitting the id parameter returns a list of tracked entities rather than a specific rate
- Network or payment failure (x402) prevents the call from completing
- Recently enacted tariff changes may not yet be reflected in the combined estimate
