HS Code for Tantalum bars

Tantalum bars obtained simply by sintering, as well as unwrought tantalum and powders, are classified under HS code 8103.20. Tantalum is a rare, highly corrosion-resistant transition metal, and its classification in Chapter 81 is reserved for \"other base metals.\" The logic for 8103.20 specifically targets the primary or \"unwrought\" forms of the metal. Because tantalum has an extremely high melting point, it is often processed through powder metallurgy. Sintering—a process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction—is the standard method for creating initial bars and rods. These sintered bars are considered unwrought because they have not yet been subjected to significant rolling, drawing, or machining to create finished shapes. This classification follows GRI 1 and the specific definitions provided in the Explanatory Notes for Chapter 81.

Products Included

• Unwrought tantalum ingots
• Sintered tantalum bars and rods
• Tantalum powder
• Tantalum blocks and billets
• Tantalum wire-bars (unwrought)

Common Misclassification

The most frequent misclassification occurs between 8103.20 and 8103.90. HS code 8103.90 is for \"Other\" tantalum products, which includes wrought bars, rods, wire, and finished articles. If a tantalum bar has been rolled or drawn after the sintering process, it is no longer considered unwrought and must be moved to 8103.90. Another potential error is 8103.30, which is reserved for tantalum waste and scrap. Importers must distinguish between primary unwrought material (8103.20) and secondary scrap material (8103.30). Finally, capacitors made of tantalum are classified in Chapter 85 (8532.21), not as the base metal itself.

FAQ

What is the HS code for tantalum powder?

Tantalum powder is classified under HS code 8103.20, along with other unwrought forms of the metal.

When does a tantalum bar move from 8103.20 to 8103.90?

A bar moves to 8103.90 once it has been further worked beyond simple sintering, such as through cold-rolling, drawing, or polishing into a finished wrought product.
