Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other refrigerants like HFC-134a
Mixtures of fluorinated hydrocarbons not specifically named fall under mixtures of halogenated derivatives in chapter 38.
If for industrial solvent use, not refrigeration
Other fluorinated acyclic hydrocarbons may classify under broader saturated fluorides if not specifically HFC-143a.
If imported in liquefied propane containers
Liquefied gases in chapter 27 if primarily propane/butane with incidental fluorocarbons.

Import Tips & Compliance
• Obtain EPA SNAP approval and ensure compliance with the American Innovation and Manufacturing (AIM) Act quotas for HFC imports
• Provide Safety Data Sheets (SDS) and confirm purity certificate (>99.9%) as required for refrigerant-grade chemicals
• Avoid misclassification as mixtures; pure HFC-143a must meet chapter 29 chemical definition without functional additives
