More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of copper-zinc base alloys (brass)
Brass alloys where zinc predominates over other elements (excluding high nickel/tin) fall under copper alloy subheading per chapter note (a).
If thickness of 0.15 mm or less
Thinner copper foils under 0.15 mm are classified in Chapter 74 heading 7407, separate from plates/sheets.
If not refined copper but copper alloys
Non-refined or alloyed copper (not meeting refined purity) uses 7409.19 for other copper plates/sheets in coils.

Import Tips & Compliance
• Verify copper purity exceeds 99.5% with mill test certificates to confirm 'refined copper' classification
• Ensure thickness measurement is precisely documented as under 5 mm but over 0.15 mm to avoid reclassification
