U.S. imports of carbonyl dichloride (phosgene) (HS 281211) totaled $74K in December 2025, traded with 1 country.
Importers of Carbonyl Dichloride (Phosgene) paid $11K in duties in December 2025 — an effective duty rate of 15% on $74K in dutiable value, based on actual customs collections rather than the published tariff schedule. Carbonyl Dichloride (Phosgene) imports of $74K in December 2025 ran 1100% above the year-to-date monthly average of $6K.
Phosgene is a highly toxic industrial chemical used primarily as a reactive intermediate in the synthesis of isocyanates, polycarbonates, and pharmaceuticals — its extreme hazard profile means shipments are tightly controlled under both domestic chemical safety regulations and international chemical-weapons conventions. Japan is the sole recorded US import supplier under this heading, reflecting the concentrated, safety-intensive nature of phosgene production globally. Importers must comply with EPA Risk Management Program requirements and should confirm that the exporting facility meets all applicable safety and documentation standards before shipment. Classification is straightforward at the single 10-digit line 2812110000, but regulatory clearance is the dominant compliance burden.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Beyond standard customs entry, phosgene is subject to EPA Risk Management Program (RMP) regulations due to its acute toxicity, and it is listed as a Schedule 3 chemical under the Chemical Weapons Convention, which requires declaration to the Organisation for the Prohibition of Chemical Weapons (OPCW). Importers should also review OSHA Process Safety Management requirements for facilities receiving the material.
Phosgene is rarely traded as a standalone commodity because of its extreme toxicity and the logistical complexity of transport. Japan's position reflects the presence of integrated chemical manufacturers who produce and consume phosgene captively or ship it in highly controlled quantities to US partners. Most global phosgene is generated and consumed on-site, making any cross-border trade unusual and highly specialized.
