U.S. imports of activated carbon (HS 380210) totaled $23.8M in April 2026, traded with 30 countries.
Importers of Activated Carbon paid $2.9M in duties in April 2026 — an effective duty rate of 15% on $19.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataFeedstock origin is the primary commercial and classification variable for activated carbon: the US tariff schedule distinguishes coal-derived (3802100010), coconut-derived (3802100020), and other activated carbon (3802100050), each serving different filtration, purification, and adsorption applications. Coconut-shell activated carbon — prized for its microporous structure in water and air purification — drives significant import volume from Sri Lanka and the Philippines, both leading suppliers. India and Mexico also rank among top sources, reflecting diversified production across agricultural and mineral carbon feedstocks. Importers should be prepared to document feedstock origin, as CBP may request evidence to support the coal versus coconut versus other classification.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP may request manufacturer's production records, feedstock purchase documentation, or a certificate of analysis specifying raw material origin. A supplier declaration or mill certificate identifying coconut shell as the carbon precursor is typically the baseline document. Without clear feedstock documentation, CBP may default to the NESOI line 3802100050.
Sri Lanka has abundant coconut shell resources and a well-developed activated carbon processing industry that has supplied global water and air purification markets for decades. Coconut-shell activated carbon's superior micropore structure for small-molecule adsorption makes it the preferred grade for drinking water treatment and gas-phase applications, sustaining strong demand from US buyers.
