Alternative Classifications

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

3824Lower: 15% vs 28.7%

If blended with lubricating oils for refrigeration systems

Mixtures of fluorinated refrigerants with additives like lubricants are classified as prepared chemical preparations in Chapter 38 rather than pure compounds.

8418.69.01Higher: 35% vs 28.7%

If imported pre-charged in refrigeration equipment

When HCFC-124 is contained within finished refrigerators or chillers, classification shifts to Chapter 84 machinery headings based on principal function.

2903.71.01.00Higher: 38.7% vs 28.7%

If containing only chlorofluorocarbons without hydrogen

CFCs (no hydrogen) like CFC-12 fall under earlier subheadings in 2903.71, while HCFCs with hydrogen like HCFC-124 are in 2903.79.
