Data Methodology

hscodedb.com is engineered on a Type-1 static sharded-registry architecture designed to deliver sub-second response times while maintaining strict data provenance.

1. Statutory Sourcing & Ingestion Pipeline

Data is ingested directly from live official government APIs and statutory publications, including the USITC HTS API, HMRC Trade Tariff Service, European Commission TARIC Database, GACC China Customs Tariff, CBSA Canadian Customs Tariff, and SAT TIGIE records.

2. Token-AND Edge Search Engine

Client and edge searches execute a token-AND match algorithm over pointer.json, indexing all 5,755 WCO 6-digit codes and product descriptions locally in under 15ms without bloated heavy dependencies.

3. YMYL Verification & Duty Hedging

Because customs duty misclassification causes real financial harm, all duty rates carry explicit date-stamps ("Verified July 2026") and direct links to official primary government sources. Where data for a specific country or code is pending, we transparently state coverage status rather than inventing rates.
