HS Code for Vinyl chloride

Vinyl chloride, also known as chloroethylene, is classified under HS code 2903.21. This classification is situated within Chapter 29 (Organic Chemicals), specifically under the heading for halogenated derivatives of hydrocarbons. Vinyl chloride is an unsaturated chlorinated derivative of acyclic hydrocarbons. As a monomer, it is a colorless gas at room temperature with a sweet odor and is highly flammable. The Harmonized System classifies separate chemically defined elements and compounds in Chapter 29, and since vinyl chloride is a specific chemical molecule (C2H3Cl), it is explicitly named in the subheadings of 2903. This classification is strictly for the monomeric gas used in the production of polyvinyl chloride (PVC) and other copolymers. The chemical purity and the absence of polymerization are the defining characteristics that keep this product in Chapter 29 rather than the plastics chapter.

Products Included

• Vinyl chloride monomer (VCM)
• Chloroethylene gas
• Liquefied vinyl chloride (under pressure for transport)
• Stabilized vinyl chloride monomer

Common Misclassification

The most frequent misclassification is with HS code 3904.10, which covers Polyvinyl Chloride (PVC). While VCM is the precursor to PVC, the monomer is a chemical (Chapter 29) and the polymer is a plastic (Chapter 39). Another potential error is classification under 2903.22 (trichloroethylene) or 2903.23 (tetrachloroethylene), which are different chlorinated hydrocarbons. Importers must ensure that the chemical structure and the number of chlorine atoms are correctly identified to distinguish between these unsaturated derivatives. Additionally, it should not be confused with vinylidene chloride (1,1-dichloroethylene), which has a different chemical profile.

FAQ

What is the HS code for Vinyl chloride?

The HS code for vinyl chloride (chloroethylene) monomer is 2903.21.

Is vinyl chloride transported as a gas or a liquid?

While it is a gas at standard temperature and pressure, it is typically transported as a liquefied gas under pressure. Regardless of this physical state, it remains classified under HS code 2903.21 as long as it is the pure monomer.
