Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lower purity or technical grade not meeting 99% threshold
Statistical suffixes distinguish purity grades within the same perhalogenated heading.
If when imported as organic composite solvent with added stabilizers
Chapter 29 excludes products with additives rendering them suitable for specific uses per note (g).
If imported pre-charged in refrigeration equipment
Machines containing refrigerants are classified by function in chapter 84, not the chemical content.

Import Tips & Compliance
• Label cylinders with UN 1028 and DOT specifications; ensure pressure vessel compliance for transport
• Provide GC-MS analysis certificates to prove absence of impurities exceeding 0.1%
• Check for anti-dumping duties or quotas on HCFC imports under U.S. environmental regulations
