HS Code 38.02 – Activated carbon; activated natural mineral products; animal black, including spent animal black

HS code 3802 is a 4-digit heading in the Harmonized System that covers: Activated carbon; activated natural mineral products; animal black, including spent animal black. Heading 3802 encompasses activated carbon, activated natural mineral products, and animal black, including spent animal black. Activated carbon, also known as activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. It is produced from various carbonaceous materials like wood, coconut shells, or coal. Activated natural mineral products include clays such as bentonite or fuller's earth that have undergone activation processes to enhance their adsorptive properties. Animal black, typically bone char, is a pigment and adsorbent derived from animal bones, and 'spent' animal black refers to the material after its adsorptive capacity has been exhausted. The scope of this heading is defined by the *activation* process, which imparts specific adsorptive or catalytic properties. These materials are crucial in numerous applications, including water and air purification, industrial gas separation, gold recovery, sugar decolorization, and pharmaceutical purification. Proper classification under 3802 is essential for trade compliance, as it distinguishes these processed materials from their unactivated counterparts (e.g., raw charcoal or clays) and ensures adherence to environmental and safety regulations for their handling and disposal. This heading is a key component of Chapter 38, which covers miscellaneous chemical products, highlighting its role in various industrial processes.

Granular activated carbon, powdered activated carbon, activated carbon pellets, activated alumina, activated bauxite, activated bentonite clay, activated fuller's earth, animal bone black, spent animal black (for regeneration), activated charcoal filters (bulk material), activated carbon for water treatment, activated carbon for air purification, activated carbon for gold recovery, activated carbon for sugar decolorization, activated carbon for pharmaceutical applications, activated carbon for gas masks, activated carbon fabric (bulk material), catalytic activated carbon, impregnated activated carbon, activated carbon for solvent recovery, activated carbon for odor control, activated carbon for automotive evaporative emissions systems, activated carbon for beverage purification, activated carbon for fish tank filters (bulk).

A common misclassification involves confusing activated carbon with unactivated charcoal (4402) or other forms of carbon that lack the enhanced adsorptive properties. The 'activated' status is the crucial differentiator. Similarly, natural mineral products like clays (2508) or bauxite (2606) are often confused if they have not undergone an activation process; 3802 specifically requires the 'activated' state. Another mistake is classifying complete filter machines or cartridges (8421) under 3802; this heading covers the *material* itself, not the apparatus containing it.

In 2025, the top exporters of HS code 3802 in UN Comtrade data were China ($559M, 15% of world exports), the United States ($540M) and India ($515M). World exports came to about $3.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 3802 in UN Comtrade data were the United States ($340M, 9.0% of world imports), Germany ($278M) and China ($209M). World imports came to about $3.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 3802 is a 4-digit heading under Chapter 38 of the Harmonized System. The first 2 digits (38) identify the chapter, and digits 3-4 (02) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
