HS Code for Bronze coil

Bronze coils fall under HS code 7409.31. This classification is determined by the material composition, the thickness of the product, and its physical form. Heading 7409 covers copper plates, sheets, and strip, of a thickness exceeding 0.15 mm. Within this heading, the 7409.3x series is dedicated to copper-tin base alloys (bronze). Subheading 7409.31 specifically identifies these products when they are presented in coils. To qualify for this code, the material must be flat-rolled and wound into a spiral or coil. The thickness is a critical factor; if the material were 0.15 mm or less, it would be classified as copper foil under heading 7410. The distinction between in coils and not in coils is the primary separator between 7409.31 and 7409.39. These products are widely used in manufacturing springs, electrical connectors, and decorative architectural elements due to their corrosion resistance and mechanical strength. Proper documentation must specify the alloy percentage to confirm the copper-tin base.

Products Included

• Rolled bronze strip in coils
• Bronze sheet metal in rolls
• Phosphor bronze coils
• Coiled bronze plate exceeding 0.15mm
• Industrial bronze ribbon in coils

Common Misclassification

Bronze coils are often misclassified under 7410.22 if the thickness is 0.15 mm or less, which designates the product as foil. They are also confused with 7409.39, which is the code for bronze sheets and plates that are not in coils (flat pieces). Another common error is using 7409.11, which is reserved for refined copper coils rather than bronze alloys.

FAQ

What is the HS code for bronze coil?

The HS code for bronze coil is 7409.31, specifically for copper-tin base alloys in coiled form with a thickness over 0.15 mm.

When does a bronze coil become bronze foil?

A bronze product is classified as foil under HS code 7410.22 when its thickness is 0.15 mm or less, regardless of whether it is in a coil.
