Unwrought Tin Powder 99.9% Pure
Fine tin powder with at least 99% tin content, not alloyed, used in metallurgy and powder injection molding. Classified under HTS 8007.00.32.00 as powders and flakes of tin, distinct from wrought forms or alloys. Meets chapter definition for non-alloyed tin due to purity exceeding 99% with minimal bismuth and copper.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in coarse granular or lump form, not powder
Coarse granules fall under unwrought tin bars, rods, profiles per 8001, not fine powders/flakes.
If tin alloy powder with Bi or Cu exceeding limits
Alloy powders where tin predominates but other elements >1% or Bi/Cu at limits classify under tin alloys.
If chemically treated for specific industrial use like soldering paste
Prepared chemical products containing tin powder shift to Chapter 38 for chemical preparations.

Import Tips & Compliance
• Verify tin purity via assay certificates to confirm non-alloyed status per chapter note (a); impurities over limits shift to alloys
• Declare as 'powders' with particle size specs; avoid misclassification as bars or unwrought in 8001
• Provide end-use documentation if for electronics to prevent scrutiny under anti-dumping rules
