Chemicals
View full HS code details

HCFC-141b, chemically known as 1,1-dichloro-1-fluoroethane, is classified under HS code 2903.73. This classification is determined by its status as a pure, chemically defined organic compound. Specifically, it falls under Chapter 29, which covers organic chemicals, and heading 2903, which is dedicated to halogenated derivatives of acyclic hydrocarbons. Within this heading, the subheading 2903.73 is reserved for dichlorofluoroethanes. The classification is based on the molecular structure of the substance, which consists of an ethane backbone where three hydrogen atoms are replaced by two chlorine atoms and one fluorine atom. As a hydrochlorofluorocarbon (HCFC), it is an ozone-depleting substance, and its specific classification allows for the monitoring of trade volumes in compliance with international environmental treaties like the Montreal Protocol.

Products Included

  • Pure 1,1-dichloro-1-fluoroethane
  • HCFC-141b for use as a blowing agent
  • HCFC-141b used as a precision cleaning solvent
  • Technical grade HCFC-141b

Common Misclassification

HCFC-141b is frequently misclassified under HS code 2903.71, which is specifically for chlorodifluoromethane (HCFC-22), or HS code 2903.74, which covers chlorodifluoroethanes (HCFC-142b). Another common error is classifying it under Chapter 38 (specifically 3824.74 or 3827.39) when it is imported as part of a mixture or a pre-blended polyol system. If the substance is not pure but mixed with other chemicals for foam production, it must be classified in Chapter 38 rather than Chapter 29.

FAQ

What is the HS code for HCFC-141b?
