Stainless Steel Compression Springs with Copper Coating
These are helical compression springs primarily made from copper-plated stainless steel wire, functioning as copper springs under HTS 7419.80.1600 due to their copper composition and spring form. They are used in automotive suspensions and industrial machinery for shock absorption.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily steel with minimal copper plating
Steel springs predominate by material weight, falling under Chapter 73 for iron or steel articles.
If imported as parts of compressors or pumps
Springs specifically for machinery in Chapter 84 are classified with the machine rather than as separate copper articles.
If imported as copper wire bars before forming into springs
Unformed copper wire profiles are under Chapter 74 heading 7407, not finished spring articles.

Import Tips & Compliance
• Verify copper content exceeds 50% by weight through lab testing to confirm classification under Chapter 74
• Provide material composition certificates to avoid reclassification as steel springs under Chapter 73
• Ensure springs are not assembled into finished goods, as that may shift to other headings
