Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If assembled into complete gas mask filters
Finished breathing appliances with activated carbon classify as articles of 9020, not bulk adsorbent.
If from animal black sources
Spent animal black or bone char specifically classifies under 3802.90.10.
If catalytic activated carbon
Activated carbon with catalytic properties for reactions moves to heading 3815 as reaction accelerators.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Certify non-impregnation with chemicals to avoid 3824 classification; plain activated carbon only
• Comply with NIOSH standards documentation if destined for US respirator manufacturing
• Declare mesh size and density to customs for proper verification of pellet form

Granular Activated Carbon from Coconut Shells
Granular activated carbon derived from coconut shells, used for water purification and air filtration. Classified under HTS 3802.90.50.00 as 'other' activated carbon not specified elsewhere in heading 3802. It undergoes activation to develop high porosity for adsorption.
Powdered Activated Carbon from Wood
Fine powdered activated carbon produced from wood sources, ideal for gold recovery in mining and wastewater treatment. Falls under HTS 3802.90.50.00 as 'other' forms of activated carbon beyond powders of 3802.10. It features high surface area for superior adsorption.
