1,1,1-Trichloroethane High Purity Solvent
High purity methylchloroform (1,1,1-trichloroethane) is a stabilized chlorinated hydrocarbon solvent used in precision cleaning for electronics manufacturing. Classified under HTS 2903.19.60.10 due to its chemical definition as a halogenated derivative of methane, fitting Chapter 29 scope for separate organic compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains more than 50% by weight other solvents
Organic composite solvents with significant methylchloroform content are classified in 3814 based on mixture composition, not the principal compound.
If unsaturated chlorinated derivative instead of saturated
Presence of double bonds changes classification from saturated acyclic (2903.19) to unsaturated chlorinated hydrocarbons (2903.29).
If prepared as a degreasing compound for metal surfaces
Formulated degreasing preparations containing 1,1,1-trichloroethane shift to Chapter 38 as industrial chemical preparations.

Import Tips & Compliance
• Provide stabilization agent details (e.g
• pentene inhibitor) in import docs as allowed under Chapter 29 note (f) without changing classification
• Confirm product meets 'chemically defined' criteria with GC-MS analysis to prevent reclassification as a mixture
• Check for phase-out restrictions under Montreal Protocol; some countries ban imports of ozone-depleting substances like methylchloroform
