HS Code for Rhenium powder

Rhenium powder is classified under HS code 8112.41. This code is situated within Chapter 81, which deals with various base metals not covered in previous chapters. Heading 8112 is the specific category for rhenium, along with other metals like beryllium and chromium. Subheading 8112.41 is specifically designated for "unwrought" forms of rhenium, which explicitly includes powders, as well as waste and scrap. In the context of the Harmonized System, "unwrought" refers to metal in its primary form, such as ingots, blocks, or powders, which have not yet been worked into specific shapes like plates or rods. Rhenium powder is often produced through the reduction of ammonium perrhenate and serves as a primary raw material for powder metallurgy. The classification is straightforward based on the physical state of the metal. Because the powder has not been sintered into a wrought shape or further manufactured into a finished article, it remains in the 8112.41 category.

Products Included

• Pure rhenium powder
• Rhenium metal granules
• Sintered rhenium blocks (unwrought)
• Rhenium pellets
• Amorphous rhenium powder

Common Misclassification

The most common misclassification occurs when rhenium powder is placed under 8112.49, which is reserved for wrought articles. Another potential error is classifying it under 3824 as a chemical mixture. While rhenium powder is used in chemical processes, as a pure metal powder, it is specifically provided for in Chapter 81. Furthermore, it should not be confused with rhenium salts or compounds, which are classified in Chapter 28 (e.g., 2841.90 for perrhenates).

FAQ

What is the HS code for Rhenium powder?

The HS code for rhenium powder is 8112.41, which includes unwrought rhenium, powders, and waste.

Is rhenium powder considered a hazardous material for shipping?

While the HS code 8112.41 defines its trade classification, its safety status depends on particle size; very fine metal powders can be flammable and may require specific UN numbers for transport.
