Tariff classification review is the structured process of determining the correct commodity code for a product under the Harmonized System (HS) or, specifically for US trade, the Harmonized Tariff Schedule of the United States (HTSUS). The classification directly establishes applicable duty rates, taxes, import restrictions, and trade remedy measures. Customs brokers, freight forwarders, and importers carry out this review based on product description, material composition, intended use, and country of origin. An incorrect tariff number can trigger back-billing, fines, or clearance holds, and systematic misclassification may be treated as customs fraud. Unlike a one-off product classification, HTSUS review is often an ongoing exercise that must be repeated whenever product specifications or trade regulations change.
