HS Code for Tungsten rods

Tungsten rods are classified under HS code 8101.94. This code specifically covers tungsten in its unwrought form, including bars and rods that have been obtained simply by the process of sintering. Sintering is the standard metallurgical process for tungsten, where powder is compressed and heated to form a solid mass without reaching the melting point. According to the Explanatory Notes to Chapter 81, bars and rods that have not been further worked than sintering are considered unwrought. If the rods undergo further processing such as rolling, drawing, or machining, they may transition to other sub-headings, but the primary sintered form remains under 8101.94.

Products Included

• Sintered tungsten bars
• Unwrought tungsten rods
• Tungsten-rhenium sintered rods
• Raw tungsten cylinders obtained by powder metallurgy
• Non-machined tungsten electrodes in rod form

Common Misclassification

Tungsten rods are often misclassified under 8101.99 if the importer assumes they are finished "articles." However, 8101.94 is more specific for the unwrought, sintered state. Another common error is using 7202.80, which is for ferro-tungsten; this is incorrect because 8101.94 is for the nearly pure metal or specific tungsten alloys, not the ferro-alloy used in steelmaking. Finally, if the rod is used as a welding electrode, it might be confused with 8515.90, but 8101.94 is preferred for the material form.

FAQ

What is the HS code for tungsten rods?

The HS code for tungsten rods that are unwrought or simply sintered is 8101.94.

What if the tungsten rod is polished or threaded?

If the rod has been further worked by polishing, threading, or precise machining, it is no longer considered "unwrought" and should be classified under HS code 8101.99.
