Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If decolorizing or 8%+ fixed carbon
Activated carbon powders specifically for sugar decolorizing with high fixed carbon classify under 3802.10.
If natural mineral-based, not activated
Natural diatomaceous earth or similar minerals without chemical/physical activation stay in Chapter 25 as natural products.
If formed into ceramic articles
Activated carbon shaped into crucibles or porous ceramics for lab use falls under heading 6909.

Import Tips & Compliance
• Include lab reports confirming particle size under 0.25mm to distinguish from granular forms
• Ensure origin certificates for wood source to comply with Lacey Act for US imports
• Watch for dustable powder rules; if mixed with pesticides, it may shift to 3808 subheadings
