HS Code for Copper spring washers

Copper spring washers are classified under HS code 741521, which covers non-threaded washers of copper or copper alloys. The classification is determined by the function of the article as a fastener and its mechanical design. Under the Harmonized System, heading 7415 includes a wide range of copper fasteners, and it is subdivided into non-threaded and threaded articles. Spring washers, which are designed to provide tension and prevent loosening due to vibration, fall under the non-threaded category. The material composition must be copper or a copper alloy (such as phosphor bronze, which is common for spring applications). This classification follows the principle that the specific function (a washer) and the material (copper) dictate the code. Unlike steel washers, which are found in Chapter 73, copper-based washers are strictly confined to Chapter 74. The 'spring' characteristic does not move the product to a different heading, as 741521 explicitly mentions 'including spring washers.' This ensures that all non-threaded copper washers, regardless of their specific mechanical tension properties, are grouped together for tariff purposes.

Products Included

Common Misclassification

Copper spring washers are often confused with steel spring washers, which are classified under HS code 731821. It is vital to verify the base metal before classification. Another common error is misclassifying them under 741533 or 741539, which are reserved for threaded articles like screws and bolts. Since washers do not have threads, they must remain in the 74152x subheadings. Finally, some may mistakenly use 7419, the 'other articles of copper' category, but 7415 is more specific and takes precedence under GRI 3(a).

FAQ

What is the HS code for Copper spring washers?

The HS code for copper spring washers is 741521, which covers non-threaded copper washers.

Can phosphor bronze washers be classified under this code?

Yes, because phosphor bronze is a copper alloy, and HS code 741521 covers both refined copper and copper alloy non-threaded washers.
