Last updated: April 2026 dataCarbon tetrachloride is a fully chlorinated methane compound historically used as a solvent and fire suppressant, now primarily traded as a chemical intermediate for fluorocarbon production. As a Class I ozone-depleting substance under the Montreal Protocol, its import into the US is tightly controlled by EPA under the Clean Air Act's allowance system, making regulatory compliance the central concern for trade professionals. Classified under HTS 2903140000, France and Germany are the leading recorded suppliers, with Sweden and Taiwan also present in the supply base. The narrow range of permitted uses and strict EPA allowance requirements mean that import volumes are closely tied to licensed production quotas rather than open-market demand.

Carbon tetrachloride is a Class I, Group I ozone-depleting substance regulated under the EPA's stratospheric ozone protection program. Importers must hold valid EPA allowances for each shipment and comply with reporting requirements under 40 CFR Part 82. TSCA certification is also required at entry. The allowance system effectively caps total import volumes, so securing allowances in advance is a prerequisite for any commercial import program.
EPA regulations provide limited exemptions for carbon tetrachloride used as a process agent or feedstock in the production of other chemicals, where the carbon tetrachloride is transformed or destroyed in the process. These exemptions are narrowly defined and require specific documentation. Importers claiming a feedstock or process-agent exemption should work with EPA and a licensed customs broker to ensure the exemption is properly documented and the shipment complies with all applicable conditions.
