Duty Rate (from China)
Products classified under Tariff item 2903.12.00.00
Dichloromethane ACS Reagent Grade
High-purity dichloromethane (methylene chloride) meeting ACS standards for laboratory use in chemical analysis and synthesis. This saturated chlorinated derivative of methane is a separate chemically defined organic compound, falling under tariff item 2903.12.00.
2903.12.00Dichloromethane Extraction Solvent
Laboratory solvent specifically packaged for liquid-liquid extraction in organic chemistry and natural product isolation. Pure dichloromethane qualifies under tariff item 2903.12.00 as a separate chemically defined compound, even when packaged for laboratory use.
2903.12.00Dichloromethane Pharmaceutical Grade USP
Ultra-pure methylene chloride meeting USP standards for use as an extraction solvent in pharmaceutical manufacturing. This chemically defined saturated chlorinated hydrocarbon is classified under tariff item 2903.12.00, provided it is not put up in measured doses or for retail sale.
2903.12.00Methylene Chloride Foam Blowing Agent
High-purity dichloromethane used as auxiliary blowing agent in polyurethane foam production. As a separate chemically defined compound, it falls under tariff item 2903.12.00, even when supplied in bulk ISO tank containers for industrial use.
2903.12.00Methylene Chloride Paint Stripper
Industrial solvent formulated primarily with dichloromethane for removing paint, varnish, and coatings from surfaces. When imported as the pure compound without additives that render it suitable for specific use, it falls under tariff item 2903.12.00.
2903.12.00Stabilized Dichloromethane Industrial
Dichloromethane with minimal cyclopentane stabilizer (<0.1%) for corrosion prevention during storage and transport. Per Chapter 29 Note 1(f), stabilizers necessary for preservation or transport do not affect classification, so it falls under tariff item 2903.12.00.
2903.12.00Technical Grade Methylene Chloride 99%
Industrial-grade dichloromethane with 99% purity for use in foam blowing, adhesives, and polymer processing. As a separate chemically defined organic compound per Chapter 29 Note 1(a), it falls under tariff item 2903.12.00.
