Perfluorohexane from Mexico
Perfluorohexane (C6F14), also known as FC-72, is a saturated perfluorinated acyclic hydrocarbon used in thermal management and precision cleaning. Classified under HTS 2903.49.00.00 as it represents 'other' saturated fluorinated derivatives beyond the shorter-chain specifics. Its high density and chemical inertness make it ideal for immersion cooling.

Import Tips
• Provide chemical analysis confirming complete fluorination (no C-H bonds) to distinguish from partially fluorinated compounds
• Declare exact carbon chain length on commercial invoice to avoid reclassification to unspecified subheadings
• Check REACH/SVHC compliance for EU transshipments due to PFAS regulatory scrutiny
