HS Code 7403Copper; refined and copper alloys, unwrought

What HS code 7403 covers

Heading 7403 is for copper metal that has been refined or mixed with other metals, but not yet shaped into a finished product. The word "unwrought" means the metal has not been rolled, drawn or worked into a final form. Think of raw blocks, sticks and plates that a factory will melt or process later.

The heading belongs to Section XV, which groups base metals. Inside it, Chapter 74 deals with copper and articles thereof. Importers in the United States often call the same code an HTS code, and many Indian traders say HSN code. The first six digits are the same in all of these systems.

The goods fall into refined copper and unwrought copper alloys, mainly brass and bronze.

HS code for copper cathodes and other refined copper (740311 to 740319)

Refined copper is split by shape. The code you pick depends on what the goods look like when they ship.

Each code below has a plain label next to the official wording.

• 740311: copper cathodes and sections of cathodes. This is the usual answer if you are asking for the hs code for copper cathodes.
• 740312: refined copper wire-bars, which are long bars used to draw wire.
• 740313: refined copper billets, which are thick round or square lengths.
• 740319: other refined copper that does not fit the three shapes above. Use it only after you have ruled out cathodes, wire-bars and billets.

HS code for unwrought brass, bronze and other alloys (740321 to 740329)

Alloys are copper mixed with another metal. The code depends on which metal is mixed in.

Brass is copper with zinc. Unwrought brass goes under 740321. Bronze is copper with tin. Unwrought bronze goes under 740322.

Any other copper alloy that has not been worked goes under 740329. This code has one clear limit: it does not take master alloys. Those are strong mixes made to be added to other metal later, and they have their own heading, 7405.

How to choose the right code under 7403 and tell it from nearby headings

Ask two questions in order. First, is the metal refined copper or an alloy? Second, what is its shape, or which metal is mixed in? The exact wording of each subheading decides the answer, so read the full description before you file. If you are unsure, try the HS code classifier.

Then check that 7403 is the right heading at all. Copper has many neighbours, and mixing them up is a common mistake.

• The copper there still has to be refined.
• 7404 is copper waste and scrap. Used or leftover metal goes there, not under 7403.
• 7405 is copper master alloys, which are kept out of 740329.
• 7407 is bars, rods and profiles. 7408 is copper wire. 7409 is plates, sheets and strip. These are worked forms, so they are not unwrought.
