Dear Sara,


According to the Dangerous Goods Regulations 10% formalin (4%formaldehyde) is not regulated by either the DOT or IATA.  The cut off for the percentage of formaldehyde in a solution that is considered a Dangerous Good and must be classified is ≥10% formaldehyde.  


So since 10% formalin is only 4% formaldehyde it is not regulated as a Dangerous Good but 10% formaldehyde is considered a "Aviation regulated liquid, n.o.s. UN3334" and subject to classification when shipping by air.  This is a common mistake for people who ship samples fixed in 10% formalin.  If you would like to discuss this further or would like additional references to confirm this please call or e-mail me.
