HS-6 · Subheading
290351
Unsaturated fluorinated derivatives of acyclic hydrocarbons; 2,3,3,3-tetrafluoropropene (HFO-1234yf), 1,3,3,3-tetrafluoropropene (HFO-1234ze) and (Z)-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz)
Heading 2903 — Halogenated derivatives of hydrocarbons
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 290351 when importing or exporting unsaturated fluorinated derivatives of acyclic hydrocarbons, such as HFO-1234yf or HFO-1234ze. For example, if you're shipping HFO-1234yf in bulk containers for use as a refrigerant, this is the correct code.
This code specifically covers fluorinated hydrocarbons that are unsaturated, distinguishing them from saturated types classified under different HS codes. For instance, HS-6 290352 includes saturated fluorinated derivatives, which have different chemical properties and uses.
When dealing with products like (Z)-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz), it's crucial to use HS-6 290351 to ensure compliance with regulations. This line is tailored for specific applications in refrigeration and foam-blowing agents.
Understanding the nuances between these HS codes is vital for accurate customs declarations and avoiding potential delays. If you are unsure whether your product fits this classification, consulting a customs broker can provide clarity.
