HS Code for Copper ash

Copper ash is classified under HS code 2620.30, which covers slag, ash, and residues containing mainly copper. This classification falls under Chapter 26 (Ores, slag, and ash) rather than Chapter 74 (Copper and articles thereof) because the material is a residue of industrial processes rather than a primary metal product or scrap. These residues typically result from the smelting of copper or the treatment of copper-bearing waste. To be classified here, the material must be of a kind used in industry either for the extraction of copper or as a basis for the manufacture of copper chemical compounds. The classification is based on the fact that the copper is not in a metallic, workable form but is instead part of a mineralized or oxidized residue.

Products Included

• Copper smelting ash
• Residues from copper scrap melting
• Brass mill scale
• Copper-rich dross from refining furnaces
• Spent copper catalysts used for metal recovery

Common Misclassification

A frequent error is classifying copper ash under HS code 7404.00 (copper waste and scrap). The distinction is that 7404.00 is for metallic waste that can be remelted directly, whereas 2620.30 is for non-metallic residues like ash and slag that require chemical or metallurgical processing to recover the metal. It is also sometimes confused with 2603.00 (copper ores and concentrates), but ores are naturally occurring minerals, while ash is a man-made industrial byproduct.

FAQ

What is the HS code for copper ash?

Copper ash and residues containing mainly copper are classified under HS code 2620.30.

Is copper scrap the same as copper ash for customs purposes?

No, copper scrap is metallic waste classified under 7404.00, while copper ash is a residue from industrial processes classified under 2620.30.
