U.S. imports of artificial graphite, colloidal graphite & carbon-based semimanufactures (SITC 59861) totaled $51.4M in April 2026, traded with 28 countries.
Importers of Artificial Graphite, Colloidal Graphite & Carbon-Based Semimanufactures paid $4.7M in duties in April 2026 — an effective duty rate of 12% on $40.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Artificial Graphite, Colloidal Graphite & Carbon-Based Semimanufactures imports of $51.4M in April 2026 ran 15% above the year-to-date monthly average of $44.6M.
Last updated: April 2026 dataArtificial graphite — manufactured by high-temperature graphitization of petroleum coke or coal tar pitch — and colloidal or semi-colloidal graphite dispersions are critical materials for electrodes in electric arc furnaces, lithium-ion battery anodes, and high-temperature lubricants. The heading also captures carbon-based semimanufactures in paste, block, or plate form, which serve as electrode blanks, EDM electrodes, and structural components in nuclear and aerospace applications. Artificial graphite for battery anodes has attracted significant trade-policy attention, and products from certain origins may be subject to Section 301 tariffs, making origin documentation and tariff engineering a priority for battery supply chain managers.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Artificial graphite and carbon-based products from certain origins — notably China — may be subject to Section 301 tariffs. The applicable rate and product scope depend on the specific HTS classification at the 10-digit level and any exclusions that may have been granted or reinstated. Importers should conduct a line-by-line HTS analysis and monitor USTR exclusion lists, as the landscape has changed frequently.
Artificial graphite is produced by graphitizing amorphous carbon precursors (typically petroleum coke) at temperatures above 2,500°C, yielding a highly ordered crystal structure. Natural graphite is mined and processed but not synthetically graphitized. The distinction matters for both tariff classification and battery anode performance specifications, as artificial graphite offers more consistent purity and electrochemical properties.
