HS-6 · Subheading
290342
Saturated fluorinated derivatives of acyclic hydrocarbons; difluoromethane (HFC-32)
Heading 2903 — Halogenated derivatives of hydrocarbons
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 290342 when importing or exporting difluoromethane, commonly known as HFC-32. This chemical is widely used as a refrigerant in air conditioning systems and as a propellant in aerosol applications.
This code specifically covers saturated fluorinated derivatives of acyclic hydrocarbons. It differs from HS-6 290341, which includes monochlorofluoromethane, highlighting the importance of the fluorine content in determining the correct classification.
When considering HS-6 290342, it’s essential to note that it applies to products that are typically in liquid form and packaged in cylinders or bulk containers for industrial use. Ensure your shipment complies with safety regulations, especially concerning refrigerants.
If you're dealing with products like HFC-32 in various forms, understanding the nuances between this HS-6 and similar codes can prevent misclassification and potential customs issues.
