Section XV: Base Metals and Articles of Base Metal
Chapter 73: Articles of iron or steel
Chapter 73 of the U.S. Harmonized Tariff Schedule covers Articles of iron or steel and sits within Section XV: Base Metals and Articles of Base Metal.
About Chapter 73
Chapter 73 contains 573 10-digit statistical lines grouped under 20 4-digit headings. Brokers, importers, and customs counsel use these codes to declare articles of iron or steel 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 73 range from 1.5% to 12.5%, with a median of 3.7%. About 20% of the chapter's lines (117 of 573) 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.

section note 2definitional
Parts of General Use
Throughout this schedule, the expression 'parts of general use' means: (a) Articles of heading 7307, 7312, 7315, 7317, or 7318, and similar articles of other base metal; (b) Springs and leaves for springs, of base metal, other than clock or watch springs (heading 9114); and (c) Articles of headings 8301, 8302, 8308, 8310.
section note 3definitional
Classification of Composite Articles
Throughout this schedule, the expression 'base metals' means: iron and steel, copper, nickel, aluminum, lead, zinc, tin, tungsten (wolfram), molybdenum, tantalum, magnesium, cobalt, bismuth, cadmium, titanium, zirconium, antimony, manganese, beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium (columbium), rhenium, and thallium.
section note 5classificatory
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.
section note 7definitional
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.
chapter note 1definitional
Scope of Chapter 73
In this chapter, the expression 'cast iron' applies to products obtained by casting in which iron predominates by weight over each of the other elements and which do not comply with the chemical composition of steel as defined in note 1(d) to chapter 72.
chapter note 2classificatory
Welded vs. Seamless Distinction
In this chapter, the word 'welded' encompasses products obtained by any process of welding, including electric resistance welding, whether or not subsequently cold-drawn or cold-rolled (cold-reduced).
chapter note Heading 7307classificatory
Tube or Pipe Fittings — Scope
Heading 7307 covers fittings used in piping systems for connecting, adapting, reducing, branching, or closing pipe runs. This includes couplings, elbows, sleeves, tees, crosses, reducers, bushings, caps, plugs, nipples, unions, flanges, and similar fittings. Flanges that are designed for connecting pipe sections fall under this heading, regardless of whether they are forged, cast, or welded. The classification between 'forged' and 'not forged' at the statistical suffix level depends on the manufacturing process.
chapter note 7307.91 Noteclassificatory
Machined vs. Not Machined After Forging
The distinction between 'not machined, not tooled and not otherwise processed after forging' and other flanges depends on whether significant material removal or surface finishing operations beyond basic trimming have been performed after the initial forging process. Basic operations such as trimming flash, shot blasting, or applying rust-preventive coatings do not constitute 'machining or tooling.' CNC machining of bolt holes, facing of sealing surfaces, or boring of bore holes to close tolerances would constitute machining after forging.

Frequently asked questions
What does HTS Chapter 73 cover?
Chapter 73 of the U.S. Harmonized Tariff Schedule (HTSUS) covers Articles of iron or steel. It sits within Section XV: Base Metals and Articles of Base Metal. Tandom's catalog lists all 573 10-digit statistical lines and 20 4-digit headings in this chapter.
What is the typical U.S. duty rate for Chapter 73 imports?
General (Column 1) duty rates for ad-valorem lines range from 1.5% to 12.5% (median 3.7%); roughly 80% 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 73 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 73 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 73 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 73 to see flagged orders, deposit rates, and the underlying scope determinations.
