Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2903.59.90.00Lower: 3.7% vs 13.7%

If purity below technical grade or contains isomers

Less pure or mixed unsaturated fluorinated hydrocarbons go to the 'Other' category rather than specific statistical suffix.

3814.00.50Higher: 41% vs 13.7%

If formulated as organic refrigerant mixture with additives

Refrigerant gas mixtures with propellants or stabilizers classify under Chapter 38 as formulated products.

2903Same rate: 13.7%

If classified as fluorinated butadiene derivative

Certain unsaturated fluorocarbons with diene structures may fall under chlorofluorinated unsaturated hydrocarbons.

Import Tips & Compliance

Obtain EPA Significant New Alternatives Policy (SNAP) approval documentation if intended for refrigerant use

Declare exact purity levels (>99%) to distinguish from formulated mixtures that might classify elsewhere

Ensure proper UN hazardous materials classification for fluorinated gases during import clearance
