HS-6 · Subheading
290374
Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; chlorodifluoroethanes HCFC-142, 142b)
Heading 2903 — Halogenated derivatives of hydrocarbons
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 290374 when importing or exporting chlorodifluoroethanes like HCFC-142 or HCFC-142b. These are commonly used as refrigerants and solvents in various applications, including air conditioning systems.
This code specifically covers halogenated derivatives of acyclic hydrocarbons that contain two or more different halogens. For example, while HS-6 290372 includes monochlorodifluoroethanes, HS-6 290374 is focused on those with a more complex halogen structure.
If you're dealing with products that contain a mix of halogens, such as both chlorine and fluorine, this HS-6 line is your go-to. It's important to distinguish it from other related codes that may cover simpler halogenated compounds.
When classifying your product, remember that the presence of multiple halogens is key. This can affect both the regulatory requirements and the duties applicable to your shipment.
