Stabilized Vinyl Chloride Monomer
Vinyl chloride monomer stabilized with inhibitors like methylhydroquinone to prevent premature polymerization during storage and transport, explicitly allowed under Chapter 29 note (f). Classified as HTS 2903.21.00.00 as the stabilizer is necessary for preservation.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stabilizer content renders it suitable for specific use
Chapter 29 note (e) excludes solutions/additives making product suitable for specific use beyond general purposes, moving to chemical preparations.
If misidentified as acyclic alcohol with halide
Alcohol halides fall under oxygen-function compounds in 2905, but vinyl chloride lacks oxygen group.
If for saturated chlorinated derivatives like chloroform
Saturated vs unsaturated acyclic chlorinated hydrocarbons separate 2903.11-19 from 2903.21+.

Import Tips & Compliance
• Document stabilizer type and concentration (<0.1% typically) to qualify under Chapter 29 note (f) rather than Chapter 38 mixtures
• Comply with IATA/UN 1086 regulations for Division 2.1 flammable gases in pressurized cylinders
• Test for polymerization degree upon arrival; any pre-polymerization may shift to Chapter 39
