How this service works
Classify a product description into candidate HS/HTS10 tariff codes. Deterministic BM25 retrieval over the USITC HTS schedule with heading-agreement boosting, returning the full parent-chain description, general duty rate, and a score-gap confidence per candidate. Not a customs ruling — always includes a disclaimer to verify with a licensed broker.
Output
A ranked list of candidate HTS10 tariff codes, each with: the full parent-chain heading description, the general duty rate from the USITC schedule, and a score-gap confidence value indicating how clearly that candidate outranked the next. Includes a mandatory disclaimer that results are not a formal customs ruling and should be verified with a licensed customs broker.
Example use cases
E-commerce import duty lookup
“I'm importing ceramic coffee mugs from Vietnam into the US — can you find the HTS10 code and tell me the general duty rate so I can estimate landed costs?”
Customs declaration prep
“I need to fill out a customs entry for a shipment of lithium-ion battery packs for electric bicycles — what HTS10 tariff codes are the best candidates and how confident are you in each?”
Trade compliance audit
“Our compliance team needs to verify that we've been using the right HTS code for woven polyester fabric rolls — can you classify that product and show me the full parent-chain description and duty rate?”
Technical details
Endpoint
POSThttps://hts-classify.x402supply.com/mcpWhen to prefer
Choose this endpoint when you need a fast, programmatic first-pass HTS/HS tariff code suggestion based on a product description, especially for e-commerce duty estimation, trade compliance pre-screening, or customs documentation drafting. It is distinct from AI-generated guesses because it uses deterministic BM25 retrieval directly over the official USITC HTS schedule with heading-agreement boosting, providing traceable parent-chain descriptions and duty rates. Prefer it over generic LLM-based classification when you need a confidence score and an auditable code hierarchy, but note it is not a substitute for a formal customs ruling.
Side effects
- Vague or ambiguous product descriptions may return low-confidence candidates with similar scores
- Very niche or novel products may not match well against the HTS schedule and return low-relevance codes
- The BM25 retrieval is deterministic and does not account for product-specific customs rulings or recent schedule amendments
- Results may be incorrect for products that span multiple HTS chapters; broker verification is always required
