Hexachlorocyclopentadiene from China
Hexachlorocyclopentadiene is a chlorinated cyclic hydrocarbon used primarily as a chemical intermediate in pesticide and flame retardant production. It falls under HTS 2903.89.70.90 as a halogenated derivative of cyclanic hydrocarbons, specifically featuring multiple chlorine atoms attached to a cyclopentadiene ring structure. This classification aligns with Chapter 29 notes for separate chemically defined organic compounds with halogen substitution.

Import Tips
• Verify chemical purity certificates to confirm it meets 'separate chemically defined compound' criteria under Chapter 29; obtain EPA TSCA registration for chemical imports; ensure proper HAZMAT labeling for chlorinated compounds to avoid customs delays
