Vinylidene Chloride
Vinylidene chloride (1,1-dichloroethene) is an unsaturated chlorinated derivative of an acyclic hydrocarbon, featuring a carbon-carbon double bond and two chlorine atoms on the same carbon. It falls under HTS 2903.29.00.00 as it matches the chapter's definition for separate chemically defined organic compounds that are halogenated derivatives of hydrocarbons. Primarily used as a comonomer in polyvinylidene chloride (PVDC) resins for food packaging films.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fully saturated structure
Saturated chlorinated derivatives like 1,1-dichloroethane fall under 2903.21 for vinyl chloride derivatives.
If imported as mixture with solvents exceeding transport safety thresholds
Solutions with solvents rendering them suitable for specific uses fall under mixtures of chapter 38 per chapter note 2(e).
If fluorinated in addition to chlorination
Chlorofluorinated unsaturated acyclic hydrocarbons are classified under 2903.39 for other halogenated derivatives.

Import Tips & Compliance
• Provide detailed chemical purity analysis and CAS number (75-35-4) documentation to confirm classification as a chemically defined compound
• Ensure compliance with TSCA registration and EPA import notifications for hazardous chemical substances
• Verify stabilizer content does not exceed levels that would reclassify under note 2(f) for added preservatives
