Heading 7403

Refined copper and copper alloys, unwrought (other than master alloys of heading 7405)

8 declarable lines

Heading 7403 covers refined copper and copper alloys in unwrought form, other than master alloys. It splits first between refined copper and copper alloys. Refined copper lines cover cathodes, wire bars, billets and other forms; alloy lines cover brass, bronze, cupro-nickel or nickel silver, and other alloys.

Products in this heading

Nickel silver unwrought billets
Other unwrought copper alloy ingots

How to choose the right subheading

Determine whether the metal is refined copper or a copper alloy, since that is the first split.
For refined copper, identify the unwrought form: cathodes and cathode sections, wire bars, billets, or other.
For copper alloys, identify the alloy base: copper-zinc (brass), copper-tin (bronze), copper-nickel or nickel silver, or other.
Confirm the goods are unwrought and not master alloys; semi-manufactured bars, rods, wire, plates, sheets, strip, foil, tubes or pipes fall in later headings.
Check whether the product is an ingot, block, billet or similar unwrought mass rather than a finished article.

Often confused with

Copper wire
Drawn or extruded wire is a semi-manufactured product, not unwrought copper.
Heading 7408
Copper bars and rods
Bars and rods are worked semi-manufactures, not unwrought forms.
Heading 7407
Copper powders and flakes
Powders and flakes are separate products, not unwrought masses.
Heading 7406
Copper plates, sheets and strip
Flat-rolled products over 0.15 mm are classified outside unwrought copper.
Heading 7409
Copper tubes and pipes
Tubular products are finished semi-manufactures, not unwrought copper.
Heading 7411

Frequently asked questions

What is the HTS code for refined copper cathodes?

Refined copper cathodes and sections of cathodes are classified under 7403.11.00.00. The general (MFN) duty rate is 1%.

What is the duty on unwrought brass?

Unwrought copper-zinc base alloys (brass) are classified under 7403.21.00.00. The general (MFN) duty rate is 1%.

How do I classify unwrought bronze?

Classify unwrought copper-tin base alloys (bronze) under 7403.22.00.00. The general (MFN) duty rate is 1%.
