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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used as pigment or not activated
Carbon black for inks or tires falls under heading 2803 as elemental carbon, lacking activation porosity.
If imported assembled in filter cartridges
Activated carbon filters complete with housing classify as filtering equipment under heading 8421, not bulk material.
If impregnated with chemical additives
Chemically treated or impregnated activated carbon for specific uses like odor control moves to prepared chemical mixtures in 3824.

Import Tips & Compliance
• Verify activation process documentation to confirm classification as activated carbon under Chapter 38, not carbon black (heading 2803)
• Provide certificates of analysis showing iodine number or surface area to prove adsorptive properties
• Avoid misclassification as unfinished activated carbon; ensure it's ready for end-use to prevent reclassification as mineral products
