Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fluorine in other inorganic compounds like nitrogen trifluoride
Other inorganic fluorine compounds not elsewhere specified go to 2853, distinct from pure elemental fluorine.
If artificial graphite fluorinated for battery applications
Fluorinated compounds on carbon substrates may classify under 2818 for artificial graphite products.
If sorbent prepared with adsorbed fluorine for lab use
Adsorbed gases on sorbent media are classified as preparations in 3824.60, not pure gases.

Import Tips & Compliance
• Comply with IATA/49 CFR packing instructions for Division 2.3 poison gases; include cryogenic handling certifications
• Declare exact purity (>99%) to avoid reclassification; pitfall is failing to specify physical state on commercial invoice
• Insure against spontaneous combustion risks; use facilities with fluorine-compatible piping
