Phosgene Gas (Carbonyl Chloride)
Phosgene is a colorless, highly toxic gas with the chemical formula COCl2, classified as a chloride oxide of carbon under HTS 2812.19.00 due to its structure containing both carbon-oxygen and carbon-chlorine bonds. It is primarily used in industrial chemical synthesis for producing polycarbonates and polyurethane precursors.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as halogenated derivative of acyclic hydrocarbons
Phosgene may be interpreted as a saturated chlorinated hydrocarbon derivative rather than a pure nonmetal halide oxide.
If imported in anhydrous liquid form for specific industrial applications
Certain pure anhydrous forms could fall under hydrogen chloride classifications if not explicitly meeting nonmetal halide oxide criteria.
If when mixed with stabilizers or solvents for safe transport
Mixtures containing phosgene with organic stabilizers are classified as chemical preparations rather than chemically defined compounds.

Import Tips & Compliance
• Obtain EPA approvals and TSCA registration prior to import due to phosgene's extreme toxicity and classification as a hazardous substance
• Ensure shipping containers meet UN specifications for toxic gases (e.g
• DOT 2P or 2Q) with proper placarding and emergency response plans
• Verify end-use declarations to avoid reclassification under chemical weapons conventions or anti-dumping duties
