Summary
Connects to government tariff schedules from USITC, Singapore Customs, CBSA, AU Border Force, and WCO to classify product descriptions into official HS codes before customs declarations or duty calculations. Two tools: hs_classify_product returns the code, 6-digit WCO parent, official source, and AI reasoning; hs_validate_code checks supplier-provided codes and flags mismatches or outdated classifications. Built by Kord Agencies as part of their pre-action validator suite. Useful when you're automating shipping manifests, validating supplier paperwork, or need to surface tariff code errors before they hit customs. Free tier gives 10 classifications per month, paid tiers add bulk validation and mismatch detection.
