HS Code for Molybdenum wire

Molybdenum wire is classified under HS code 810296. In the context of the Harmonized System, wire is defined as a cold-drawn product, of any cross-sectional shape, of which no cross-sectional dimension exceeds a certain limit (typically 6mm). Molybdenum wire is widely used in high-temperature applications, such as heating elements and support structures in vacuum furnaces, due to its exceptionally high melting point and low thermal expansion. The classification under 810296 is specific to the metallic wire itself. If the wire is further processed, such as being insulated for electrical use, it may be reclassified under Chapter 85. However, bare molybdenum wire, regardless of its thickness or finish (e.g., cleaned, etched, or as-drawn), remains within this specific subheading of Chapter 81. The classification logic follows the progression from raw metal to semi-finished forms, where wire is considered a distinct category from bars, rods, or plates due to its manufacturing process (drawing) and its resulting physical characteristics.

Common Misclassification

Molybdenum wire is frequently confused with molybdenum bars and rods classified under HS code 810295. The distinction is based on the manufacturing method and the diameter; wire is drawn, while bars are usually rolled or extruded. It is also sometimes misclassified under 8544 if it is intended for electrical use, but 8544 only applies if the wire is insulated or fitted with connectors.

FAQ

What is the HS code for Molybdenum wire?

The HS code for molybdenum wire is 810296.

Is molybdenum wire used in medical devices classified here?

Yes, if the wire is imported as a raw material or semi-finished component, it remains under 810296, unless it has been further manufactured into a specific identifiable part of a medical instrument.
