About HTS Chapter 38 — Miscellaneous Chemical Products
HTS Chapter 38 covers miscellaneous chemical products under the US Harmonized Tariff Schedule (HTS). The HTS is maintained by the US International Trade Commission (USITC) and updated periodically to reflect trade policy changes including executive orders, Section 232 national security tariffs, Section 301 China tariffs, and Section 122 emergency tariffs.
To import goods under Chapter 38, US importers must declare the correct 10-digit HTS code on their Customs entry. The duty rate shown is the general (MFN) rate. Special rates may apply under free trade agreements (FTAs) such as USMCA, CPTPP, or bilateral agreements. Use the FTA Checker to see if preferential rates apply to your shipment.
Anti-dumping (AD) and countervailing duty (CVD) orders may impose additional duties on specific products and countries of origin beyond the rates shown here. Always consult with a licensed customs broker for classification decisions.
