Dear Mr. Croft:
This responds to your letter requesting the proper classification of 10% buffered formalin under
the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). In your letter, you state
your 10% Formalin solution contains 3.5-4% formaldehyde solution. You also state that based
on the International Civil Aviation Organization entry, a formaldehyde solution that is less than
10% solution is not regulated as aviation regulated liquid, n.o.s. UN 3334. You ask whether a
10% buffered formalin with 3.5-9.9% formaldehyde solution is not regulated by any mode of
transportation.
As provided by § 173.22 of the HMR, it is the shipper's responsibility to properly class a
hazardous material. This Office generally does not perform this function. Manufacturers,
generally have the knowledge to properly class the materials and products they produce,
although it may be necessary to enlist an outside laboratory to assist in the classification process
as testing may have tobe conducted to determine how a product compares to the criteria for the
various hazard classes. However, although you did not provide sufficient information, such as a
Material Safety Data Sheet, the acute effects of Formaldehyde Solutions have been well
documented. A 10% Formalin (3-5% formaldehyde solution), typicalJy used to preserve·
biological samples, meets the definition for a Class 9 material in § 173.140 and is subject to
regulation when transported domestically by air. The appropriate shipping description is "Other
Regulated Substances, liquid, n.o.s. (formaldehyde), 9, NA3082, IlLfI Generally, solutions of
less than a 10% formalin mixed with non-hazardous materials are not subject to the HMR,
provided they do not meet the definition of a class 9 hazardous material or any other hazard
class.
1 hope this satisfies your request.
Sincerely,
r~0L~~-···

There seems to be some confusion about the classification of a 10% Buffered Formalin.
A 10% Formalin contains 3.5-4.0% Formaldehyde Solution. Based on the ICAO entry a
formaldehyde solution less than 10% is not regulated as an Aviation regulated liquid,
n.o.s. UN3334.
I am requesting a letter to take to suppliers that a 10% buffered formalin with 3.5-9.9%
formaldehyde solution is not regulated by any mode oftransportation.
Ifyou require any additional information please let me know.
Sincerely,
Clifford Croft
