Tariff compliance check for new product line
“We're about to source LED strip lights from a Chinese manufacturer. Can you look up the applicable HTS codes and check whether there are any Section 301 China tariffs we need to factor in?”

Endpoint
GEThttps://dutyfinch.cybermaxtools.com/x402/api/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly look up US import duty rates and/or China Section 301 tariffs for a specific product or HTS code prefix without building a full customs data integration. It is ideal for e-commerce landed cost calculations, sourcing decisions, and trade compliance checks where a single unified call returning both base duty and Section 301 surcharge data is more efficient than querying separate government databases.
Side effects
- No results found for vague or misspelled product descriptions
- Ambiguous product terms may return unrelated HTS codes
- HTS code prefix too short may return too many broad results
- Rate limits or payment failures returning 402 errors
- Outdated tariff data if schedule changes haven't been reflected
