Import Tips
• Document fluorine content and keto-acid structure to affirm halogenated derivative status per heading notes on derivatives
• Ship under temperature control if volatile; declare as pure compound to stay in chapter 29, avoiding mixture headings
• Check for REACH-like compliance on fluorochemicals; provide CAS number (372-37-2) on commercial invoice
