hs_classify_productClassifies a product description to its official 6-digit HS code. Call this BEFORE your agent generates any invoice, customs declaration, or duty calculation — at the moment a product description is known and no filing has been made. Use this when your agent is about to generate a customs document or calculate import duties and needs the correct tariff code for a product. Returns verified 6-digit HS code with WCO classification, official tariff description, and AI confidence level. An incorrect HS code on a customs declaration creates a compliance violation regardless of intent — penalties apply to the operator. Do not file any customs document without a verified HS code from this tool.
hs_validate_codeValidates a supplier-provided HS code against official tariff schedules. Call this BEFORE your agent submits any document containing an HS code to a customs authority, freight forwarder, or trade finance platform — at the moment a code is received from a supplier and has not yet been submitted. Use this when a supplier has provided an HS code on an invoice or packing list and your agent needs to verify it is valid before submitting shipment documentation. Returns VALID/INVALID/MISMATCH/OUTDATED verdict with the official description for the code. Do not use as a substitute for hs_classify_product when your agent needs to determine the correct code — this tool only validates a code you already have.
