How this service works
Applied import tariffs from the World Bank WITS / UNCTAD TRAINS database for one importing country and one HS 6-digit product: yearly simple-average rate (%), tariff type (MFN or preferential), min and max line rates and number of tariff lines, from WITS's public SDMX API. Partner defaults to the world (MFN). Non-tariff measures are not included.
Output
A JSON object containing the reporter country and partner details, the queried HS product code, and an array of yearly tariff records each with: year, simple-average applied rate (%), min and max tariff line rates (%), number of tariff lines, tariff type (MFN or preferential), and HS nomenclature version. Also includes the underlying WITS SDMX source URL and a checkedAt timestamp.
Example use cases
Automotive import duty check
“I'm planning to export sedans with HS code 870323 to Turkey — can you pull the last 5 years of applied MFN tariff rates from WITS so I can see the duty trend?”
Electronics trade compliance research
“What import tariff does the USA currently apply to laptops (HS code 847130)? Pull the last 3 years from the World Bank WITS database so I can compare year over year.”
Agricultural commodity tariff benchmarking
“Look up Brazil's applied import tariff for crude palm oil, HS code 151110, for the past 5 years — I need the average rate, min, max, and number of tariff lines each year.”
Technical details
Endpoint
GEThttps://api.tradeenergy-api.workers.dev/api/energy/world-customs-tariff-wits?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need applied import tariff rates (MFN or preferential simple averages) for a specific HS 6-digit product and importing country, sourced from the authoritative World Bank WITS/UNCTAD TRAINS database. Prefer this over customs authority websites when you need structured, machine-readable multi-year tariff history across many countries in a single API call. Note: does not cover non-tariff measures (NTMs), anti-dumping duties, or VAT.
Side effects
- Invalid or unsupported HS 6-digit product code returns no tariff data or an error
- Unknown reporter country ISO code results in a 400 or empty response
- Product/country combination not covered in TRAINS database returns empty tariff array
- WITS upstream SDMX API unavailable causes a timeout or 502 error
- Requesting years beyond available data coverage returns partial or empty results
