Vinyl Chloride Monomer (VCM)
Vinyl chloride monomer is a colorless gas at room temperature with the chemical formula CH2=CHCl, classified under HTS 2903.21.00.00 as an unsaturated chlorinated derivative of acyclic hydrocarbons. It serves as the primary raw material for polyvinyl chloride (PVC) production through polymerization processes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If liquefied and shipped as propane-like gas without chemical specification
Liquefied petroleum gases including certain unsaturated hydrocarbons are classified in Chapter 27 if not meeting Chapter 29's chemically defined criteria.
If already polymerized into PVC
Polymerized vinyl chloride becomes polyvinyl chloride (PVC) powder or resin, classified under Chapter 39 as polymers.
If mixed with stabilizers or other additives exceeding Chapter 29 allowances
Chemical preparations with added substances beyond stabilizers for safety/transport fall under mixtures of Chapter 38.

Import Tips & Compliance
• Obtain proper hazardous material declarations (HazMat) as vinyl chloride is flammable and carcinogenic; comply with DOT and IMDG regulations
• Verify purity certificates (typically >99.9%) to confirm classification as chemically defined compound under Chapter 29
• Avoid misclassification by ensuring shipment is not polymerized PVC resin, which falls under Chapter 39
