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 US HTS code, international HS6 code, official USITC description path, US MFN general duty rate, applicable special program rates (e.g. GSP, FTA), a confidence score (0–1), the LLM's classification reasoning, and a list of plausible alternate HTS codes with their descriptions.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://toolcall.click/t/hs/classifyWhen to prefer
Use this endpoint when you need authoritative, LLM-assisted HTS/HS tariff classification grounded in the live USITC schedule rather than a static database lookup. Ideal for import compliance workflows, landed cost calculations, customs documentation, and trade analytics where a plain-English description is the only input available and a human-readable reasoning trail is required.
Side effects
- Ambiguous or too-short product description yields low-confidence classification with multiple alternates
- Invalid or unsupported destination country ISO code may fall back to US duty rates
- Description exceeding 500 characters is rejected
- Payment failure via x402 returns 402 with no classification result
- Product category not covered in current USITC schedule returns an error or null code
