Section VI: Products of the Chemical or Allied Industries
Chapter 38: Miscellaneous chemical products
Chapter 38 of the U.S. Harmonized Tariff Schedule covers Miscellaneous chemical products and sits within Section VI: Products of the Chemical or Allied Industries.
About Chapter 38
Chapter 38 contains 214 10-digit statistical lines grouped under 17 4-digit headings. Brokers, importers, and customs counsel use these codes to declare miscellaneous chemical products on entry summaries (CBP Form 7501) and to look up the applicable Column 1, Special, and Column 2 duty rates.
General (Column 1) duty rates for ad-valorem lines in Chapter 38 range from 0.1% to 6.5%, with a median of 5%. About 18% of the chapter's lines (38 of 214) enter duty-free under the general rate. Special-program rates (USMCA, KORUS, GSP, AGOA, and others) and Chapter 99 overlays modify these base rates for qualifying shipments.
Every code page links into the Tandom Tariff Calculator with the HTS code prefilled, so you can compute the full landed duty for a specific shipment by entering value, country of origin, and (where relevant) material content or date of entry. Tandom's data refreshes daily from USITC HTSUS, CBP CSMS, the Federal Register, and the Department of Commerce — the same authoritative sources the trade community files against.

Frequently asked questions
What does HTS Chapter 38 cover?
Chapter 38 of the U.S. Harmonized Tariff Schedule (HTSUS) covers Miscellaneous chemical products. It sits within Section VI: Products of the Chemical or Allied Industries. Tandom's catalog lists all 214 10-digit statistical lines and 17 4-digit headings in this chapter.
What is the typical U.S. duty rate for Chapter 38 imports?
General (Column 1) duty rates for ad-valorem lines range from 0.1% to 6.5% (median 5%); roughly 24% of lines enter duty-free. Use the calculator linked from each code page to compute the full landed rate, including Section 301/232 overlays, IEEPA tariffs, and AD/CVD deposits where applicable.
Are Section 301 or Section 232 tariffs applied to Chapter 38 products?
Section 301 (China) and Section 232 (steel, aluminum, copper) tariffs are layered on top of the base HTSUS rate via Chapter 99 provisions. Whether they apply to a specific 10-digit line in Chapter 38 depends on the product's country of origin, material content, and the active proclamation. Open any code in this chapter to see the live overlay stack and effective rate.
Are there antidumping or countervailing duty (AD/CVD) orders covering Chapter 38 products?
AD/CVD orders are issued at the case level by the Department of Commerce against specific products from specific countries. Tandom's AD/CVD catalog cross-references every active order to the HTS codes it covers — open any code in Chapter 38 to see flagged orders, deposit rates, and the underlying scope determinations.
