Products classified under Tariff item 2903.21.00.00
Industrial Grade Vinyl Chloride Gas
Industrial-grade vinyl chloride gas, chemically defined as C2H3Cl, is an unsaturated chlorinated derivative of acyclic hydrocarbons. Imported in pressurized cylinders, it serves as the primary feedstock for manufacturing rigid PVC pipes and vinyl products. This product falls squarely under tariff item 2903.21.00 as vinyl chloride (chloroethylene).
2903.21.00Stabilized Vinyl Chloride Monomer
Stabilized vinyl chloride monomer contains inhibitors like methylhydroquinone to prevent premature polymerization during storage and transport. Chapter 29 note 1(f) permits added stabilizers necessary for preservation or transport, provided they do not make the product suitable for a specific use. This remains classifiable under tariff item 2903.21.00 as vinyl chloride (chloroethylene).
2903.21.00Vinyl Chloride (Chloroethylene) 99.99% Pure
High-purity vinyl chloride (chloroethylene) at 99.99% is a separate chemically defined organic compound per Chapter 29 note 1(a). As an unsaturated chlorinated acyclic hydrocarbon, it is specifically named in tariff item 2903.21.00. This product is used in synthesizing PVC and other vinyl-based polymers.
2903.21.00Vinyl Chloride for PVC Suspension Polymerization
Specialty vinyl chloride monomer formulated for suspension polymerization remains a pure chemically defined compound under tariff item 2903.21.00. It is used to produce PVC resins for pipes, fittings, and profiles. The formulation does not alter its chemical identity as vinyl chloride (chloroethylene).
2903.21.00Vinyl Chloride Monomer (VCM)
Vinyl chloride monomer (VCM) is a colorless gas with the chemical formula CH2=CHCl, classified under tariff item 2903.21.00 as an unsaturated chlorinated derivative of acyclic hydrocarbons. It serves as the primary building block for PVC production. This product is specifically named in the tariff item description.
