Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as certified reference material with calibration certificate
Diagnostic or laboratory reagents with specific diagnostic claims fall under Chapter 38 per note exclusions.
If containing heavy isotopes for tracer studies
Isotopically labeled compounds are classified under Chapter 28 inorganic/organic heavy water and isotopes.
If when packaged as gas chromatography calibration standard
Instruments and apparatus for physical/chemical analysis take precedence over chemical composition.

Import Tips & Compliance
• Small quantity research imports (<25kg/year) may qualify for EPA de minimis exemption from HFC quotas
• Include institutional end-user statement and SDS with GC-MS purity analysis for customs clearance
• Avoid declaring as 'commercial refrigerant' which triggers stricter industrial quotas and documentation
