HS Code for Copper bolts

Copper bolts are categorized under HS code 7415.33, which specifically covers threaded screws, bolts, and nuts made of copper. The classification is determined by two primary factors: the material composition and the presence of internal or external threading. Under the Harmonized System, fasteners are grouped by their base metal, and copper-based fasteners, including those made from brass or bronze alloys, fall under heading 7415. The subheading 7415.33 is reserved for those items that are threaded, distinguishing them from non-threaded fasteners like nails or rivets. These bolts are typically used in environments where corrosion resistance or high electrical conductivity is required, such as in marine applications, electrical switchgear, or chemical processing plants. The classification remains consistent regardless of the specific head shape, such as hexagonal, square, or round, as long as the primary function is that of a threaded bolt. It is important to ensure that the alloy used is predominantly copper by weight to maintain this classification.

Products Included

Common Misclassification

Copper bolts are often misclassified under HS code 7318, which is the heading for iron or steel bolts. Importers must verify the base metal composition to avoid this error. Another common mistake is using HS code 7415.21, which is reserved for non-threaded copper nails and tacks, or HS code 7415.39, which is a residual category for other threaded copper articles that do not meet the specific definition of a bolt or screw.

FAQ

What is the HS code for copper bolts?

The HS code for threaded copper bolts, screws, and nuts is 7415.33.

Are brass bolts classified under the same HS code as copper bolts?

Yes, because brass is a copper alloy, brass bolts are classified under HS code 7415.33 along with pure copper bolts.
