Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing other halogenated derivatives beyond specified HFCs
Mixtures with halogenated compounds not specifically listed as HFCs fall under the residual 'other' halogenated mixtures.
If contains oxidation inhibitors classifying as refrigerant additive composition
Antiknock or antithetic preparations for specific fuels/liquids including refrigerants go to heading 3811.
If classified as anti-freeze preparations rather than refrigerant
Products primarily preventing freezing in non-refrigeration applications are anti-freeze preparations in 3820.

Import Tips & Compliance
• Include ASHRAE safety classification (A1 refrigerant) documentation; critical for customs verification of proper handling
• Declare exact mass percentages via HPLC certificate; small deviations can trigger reclassification to 3827.62
• Budget for additional bonding requirements due to high environmental compliance scrutiny on HFC imports
