Micronized Ground Barytes Filler
Ultra-fine ground natural barytes with particle sizes under 5 microns, used as a functional filler in paints, coatings, and plastics to enhance density and abrasion resistance. Classified under HTS 2511.10.10.00 due to its origin as ground natural barium sulfate without further chemical alteration.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If precipitated or chemically synthesized
Lab-produced barium sulfate is an inorganic chemical salt under heading 2833, not a natural ground mineral.
If pre-mixed into paint pigments or colorants
Incorporation into finished inorganic pigments shifts classification to Chapter 32 for coloring matter.
If for unground, lumpy barytes
Crude barytes without grinding remains in the unprocessed subheading.

Import Tips & Compliance
• Provide mesh size or micron ratings on packaging and docs to prove 'ground' status and differentiate from coarser crude forms
• Ensure no surface treatments like silane coating, as those could reclassify to 3824 as modified preparations
• Declare exact barium sulfate assay percentage to comply with customs valuation and prevent disputes over purity
