Of copper alloys

This code covers copper tube or pipe fittings and related components made of copper alloys. Use this code when importing these fittings, keeping in mind a general duty rate of 3% applies, with potential for free duty based on eligibility for specific trade agreements or preference programs as detailed in the duty information.

Detailed information for HTS Code 7412.20.00

This tariff code falls within Chapter 74, which covers copper and articles thereof, and specifically addresses fittings for copper tubes or pipes made of copper alloys. Code 7412.20.00 covers these fittings, and further breakdown is provided by statistical suffixes indicating specific types, such as those for brake hoses or threaded brass nipples. When classifying, select the appropriate suffix based on the fitting’s material (brass, other), threading (threaded, other), and intended use, like brake applications or as a nipple. The statistical suffixes provide increasing specificity, allowing for detailed trade data collection on different types of copper alloy fittings.

Eligible FTA or preference programs

The general duty rate for HTS code 7412.20.00 and all its subdivisions is 3%, applicable to goods reported in kilograms. Special duty rates of Free apply to imports from countries with eligible Free Trade Agreements (FTAs) or preference programs, including Australia (AU), Bahrain (BH), and others listed. These reduced rates are contingent upon meeting the rules of origin requirements for the specific FTA or program; otherwise, the general 3% rate applies. The subdivisions (7412.20.00.15, 7412.20.00.25, etc.) all fall under the same duty structure – either the 3% general rate or Free if eligible for preferential treatment.

Rate of Duty (Column 2): 49%

Harmonized Tariff Schedule of the United States Revision 29 (2025) Annotated for Statistical Reporting Purposes CHAPTER 74 COPPER AND ARTICLES THEREOF XV 74-1 Note 1. In this chapter the following expressions have the meanings hereby assigned to them: (a) Refined copper Metal containing at least 99.85 percent by weight of copper; or Metal containing at least 97.5 percent by weight of copper, provided that the content by weight of any other element does not exceed the limit specified in the following table: TABLE - Other elements Element Limiting content percent by weight Ag Silver 0.25 As Arsenic 0.5 Cd Cadmium 1.3 Cr Chromium 1.4 Mg Magnesium 0.8 Pb Lead 1.5 S Sulfur 0.7 Sn Tin 0.8 Te Tellurium 0.8 Zn Zinc 1 Zr Zirconium 0.3 Other elements*, each 0.3 * Other elements are, for example, Al, Be, Co, Fe, Mn, Ni, Si. (b) Copper alloys Metallic substances other than unrefined copper in which copper predominates by weight over each of the other elements, provided that: (i) The content by weight of at least one of the other elements is greater than the limit specified in the foregoing table; or (ii) The total content by weight of such other elements exceeds 2.5 percent. (c) Master alloys Alloys containing with other elements more than 10 percent by weight of copper, not usefully malleable and commonly used as an additive in the manufacture of other alloys or as deoxidants, desulfurizing agents or for similar uses in the metallurgy of nonferrous metals. However, copper phosphide (phosphor copper) containing more than 15 percent by weight of phosphorus falls in heading 2853. Subheading Note 1. In this chapter the following expressions have the meanings hereby assigned to them: Harmonized Tariff Schedule of the United States Revision 29 (2025) Annotated for Statistical Reporting Purposes XV 74-2 Subheading Note (con.) (a) Copper-zinc base alloys (brasses) Alloys of copper and zinc, with or without other elements.When other elements are present: - zinc predominates by weight over each of such other elements; - any nickel content by weight is less than 5 percent (see copper-nickel-zinc alloys (nickel silvers)); and - any tin content by weight is less than 3 percent (see copper-tin alloys (bronzes)). (b) Copper-tin base alloys (bronzes) Alloys of copper and tin, with or without other elements.When other elements are present, tin predominates by weight over each of such other elements, except that when the tin content is 3 percent or more the zinc content by weight may exceed that of tin but must be less than 10 percent. (c) Copper-nickel-zinc base alloys (nickel silvers) Alloys of copper, nickel and zinc, with or without other elements.The nickel content is 5 percent or more by weight (see copper-zinc alloys (brasses)). (d) Copper-nickel base alloys Alloys of copper and nickel, with or without other elements but in any case containing by weight not more than 1 percent of zinc.When other elements are present, nickel predominates by weight over each of such other elements. Additional U.S. Note 1. The deduction provided for in additional U.S. note 1 to chapter 26 shall apply to cement copper and copper precipitates of subheading 7401.20. Statistical Note 1. For the purposes of this chapter, the term "beryllium copper master alloy" refers to master alloys which contain by weight at least 3 percent but not more than 10 percent beryllium.
