About HS Code 290373
This HS code specifically identifies dichlorofluoroethanes, with a primary focus on HCFC-141b. HCFC-141b was extensively used as a blowing agent in the production of rigid polyurethane foams, a precision cleaning solvent in various industries, and a component in certain aerosol propellants. Its significant ozone-depleting potential led to its accelerated phase-out under the Montreal Protocol, with production and consumption largely ceased in developed countries and rapidly phasing out in developing nations. Consequently, international trade in HCFC-141b is now highly restricted, primarily limited to very specific, authorized critical uses or for destruction and recycling purposes. Importers and exporters are typically specialized chemical companies or those involved in managing legacy equipment and waste streams.
Products Under This Code

Common Misclassification
Can be confused with other HCFCs, especially HCFC-142b (2903.74), due to similar chemical structures and applications, requiring careful distinction by specific isomer.
Products Classified Under 2903.73
Industry
This code belongs to the Chemicals industry.
Trade Overview
China was a major producer, and developing countries previously imported it for foam manufacturing, but global trade is now minimal due to phase-out.
Frequently Asked Questions
What is HS code 290373?
HS code 290373 covers: Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; dichlorofluoroethanes (HCFC-141, 141b).
