In coils

HTS code 7409.21.00 covers copper-zinc base alloys (brass) in coils, with a thickness exceeding 0.15mm. Use this code when importing these brass materials, keeping in mind a general duty rate of 1.9% applies unless the goods qualify for free trade agreements with designated countries as outlined in the duty details and chapter notes.

Detailed information for HTS Code 7409.21.00

This tariff code falls within Chapter 74, which covers copper and articles thereof, and specifically addresses copper plates, sheets, and strip made of brass (copper-zinc alloys) that are supplied in coils. The code 7409.21.00 covers these brass coils exceeding 0.15mm in thickness. Further statistical reporting is based on thickness and width—choose 7409.21.00.10 for material 5mm or more thick, 7409.21.00.50 for less than 5mm thick and 500mm or more wide, 7409.21.00.75 for less than 5mm thick, less than 500mm wide, and less than 1.6mm thick, or 7409.21.00.90 for all other brass coils less than 5mm thick and less than 500mm wide.

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.
