Section XV: Base Metals and Articles of Base Metal
Chapter 79: Zinc and articles thereof
Chapter 79 of the U.S. Harmonized Tariff Schedule covers Zinc and articles thereof and sits within Section XV: Base Metals and Articles of Base Metal.
About Chapter 79
Chapter 79 contains 13 10-digit statistical lines grouped under 2 4-digit headings. Brokers, importers, and customs counsel use these codes to declare zinc and articles thereof 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 79 range from 1.5% to 4.2%, with a median of 3%. About 8% of the chapter's lines (1 of 13) 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.

Alloy Classification Rules
Classification of alloys: (a) Alloys of base metals with each other are to be classified as alloys of the metal which predominates by weight over each of the other metals; (b) Alloys of base metals of this section with elements not falling within this section are to be classified as alloys of base metals of this section if the total weight of such metals equals or exceeds the total weight of the other elements present; (c) Sintered mixtures of metal powders, heterogeneous intimate mixtures obtained by melting (other than cermets), and intermetallic compounds are classified as alloys.
Iron vs. Nonalloy Steel vs. Stainless
(a) 'Iron and nonalloy steel' covers iron and steel containing by weight 2% or less of carbon and, except for certain specific steels, less than designated percentages of chromium, manganese, nickel, and other alloy elements. (b) 'Stainless steel' covers alloy steels containing by weight 1.2% or less of carbon and 10.5% or more of chromium, with or without other elements. (c) 'Other alloy steel' covers steels not meeting the definition of stainless steel containing specific minimum percentages of alloy elements.

Frequently asked questions
What does HTS Chapter 79 cover?
Chapter 79 of the U.S. Harmonized Tariff Schedule (HTSUS) covers Zinc and articles thereof. It sits within Section XV: Base Metals and Articles of Base Metal. Tandom's catalog lists all 13 10-digit statistical lines and 2 4-digit headings in this chapter.
What is the typical U.S. duty rate for Chapter 79 imports?
General (Column 1) duty rates for ad-valorem lines range from 1.5% to 4.2% (median 3%); roughly 9% 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 79 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 79 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 79 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 79 to see flagged orders, deposit rates, and the underlying scope determinations.
