Import Tips & Compliance
• Verify the grain size—if 90% or more passes through a 1mm sieve, it may be classified as powder under section note 8
• Ensure the nickel content meets the 5% threshold for nickel silver
• Confirm the product is not considered waste or scrap

Admiralty Brass Billet
Unwrought copper-zinc alloy billet with 1% tin addition for corrosion resistance in marine applications. As a brass with tin content under 3%, it is classified under 'other copper alloys' in tariff item 7403.29.00.
Aluminum Bronze C95400 Ingot
Aluminum bronze C95400 ingot, containing 85% copper, 11% aluminum, 4% iron, and 3% nickel, in unwrought form. Aluminum predominates over other alloying elements, classifying it as an 'other copper alloy' under tariff item 7403.29.00, distinct from brasses, bronzes, or nickel silvers defined in the subheading notes.
Architectural Bronze C38500 Ingot
Architectural bronze C38500 ingot, an unwrought copper alloy with 57% copper, 41% zinc, and 2% lead, used for ornamental work. Although called 'bronze,' the zinc content exceeds tin, and with tin below 3%, it does not meet the subheading note definition of bronze, thus classifying as an 'other copper alloy' under 7403.29.00.
Architectural Bronze Ingot
Low-tin copper-zinc alloy ingot with less than 3% tin for architectural castings. As a brass rather than a true bronze, it is classified under 'other copper alloys' in tariff item 7403.29.00.
Beryllium Copper C17300 Ingot
Beryllium copper C17300 ingot, an unwrought alloy of 96% copper, 1.9% beryllium, and 0.2% lead, used for high-strength connectors and springs. Beryllium is not one of the elements defining brasses, bronzes, or nickel silvers, so this alloy falls under 'other copper alloys' in tariff item 7403.29.00.
Cartridge Brass Anode
Unwrought 70/30 copper-zinc alloy castings used as anodes in electroplating baths. As a copper-zinc base alloy (brass), it is classified under 'other copper alloys' in tariff item 7403.29.00.
