Technical details
Endpoint
GEThttps://api.agentstools.dev/trade/htsWhen to prefer
Use this endpoint when you need to look up US import tariff classifications, duty rates, or HTS codes for specific goods — whether starting from a product description keyword or an existing partial HTS/HS code. Prefer this over general web search when you need structured, authoritative HTS data with duty-rate columns and footnotes in a machine-readable format. Ideal for trade compliance workflows, cost estimation for imports, or building tariff classification tools.
Side effects
- No matching HTS lines found for the given keyword or code — returns empty result set
- Invalid HTS code format (fewer than 4 or more than 10 digits) — returns validation error
- Both 'keyword' and 'hts' omitted — returns error requiring at least one search parameter
- Limit out of range (below 1 or above 60) — returns parameter validation error
- Payment not provided or insufficient — returns 402 Payment Required
- Ambiguous keyword returns too many unrelated results — caller should refine keyword or use a specific HTS code
