How this service works
Classify any product to its HS / HTS customs code from a plain-English description. Expert LLM classification grounded in the live official USITC Harmonized Tariff Schedule: returns the 10-digit HTS code, international HS6, official description path, US duty rate (general + special programs), confidence, reasoning and alternates. JSON response. $0.04 USDC per call, pay via x402, no API key.
Output
A JSON object containing the 10-digit HTS code, 6-digit international HS code, official USITC description path, US MFN general duty rate, applicable special program duty rates (e.g. GSP, USMCA), a confidence score (0-1), LLM reasoning for the classification, and a list of alternate HTS codes with their descriptions.
Example use cases
Example prompt
“What is the 10-digit HTS code and US import duty rate for 'men's leather dress shoes with rubber soles, not waterproof'? I need the confidence score and any alternate classifications too.”

Endpoint
GEThttps://toolsmith-api.dassad10.workers.dev/t/hs/classifyWhen to prefer
Use this endpoint when you need fast, LLM-grounded HTS/HS classification from a plain-English product description, especially when you also need the US duty rate and special trade program rates in a single call without maintaining a tariff database. Prefer this over manual USITC lookups or generic text search when you want structured JSON with confidence scoring and reasoning.
Side effects
- Ambiguous product description leads to low-confidence classification with multiple alternates
- Description exceeds 500 characters — request rejected
- Invalid destination country ISO code returns an error
- Product is too novel or niche for the LLM to classify reliably
- Payment via x402 fails, blocking the request
- Rate limit or worker timeout on the Cloudflare edge
