Packagings containing mate-

rials classed as ORM-D. 

(a) Each non-bulk packaging con-

taining a material classed as ORM–D 
must be marked on at least one side or 
end with the ORM–D designation im-
mediately following or below the prop-
er shipping name of the material. The

§ 173.144, that is packaged in accordance 
with §§ 173.63(b), 173.150 through 173.156, 
and 173.306. 

(b) When the ORM-D marking includ-

ing the proper shipping name can not 
be affixed on the package surface, it 
may be on an attached tag. 

(c) The marking ORM-D is the cer-

tification by the person offering the 
packaging for transportation that the 
material is properly described, classed, 
packaged, marked and labeled (when 
appropriate) and in proper condition 
for transportation according to the ap-
plicable regulations of this subchapter. 
This form of certification does not pre-
clude the requirement for a certificate 
on a shipping paper when required by 
subpart C of this part.
