Marine pollutants. 

(a) For vessel transportation of each 

non-bulk packaging that contains a 
marine pollutant— 

(1) If the proper shipping name for a 

material which is a marine pollutant 
does not identify by name the compo-
nent which makes the material a ma-
rine pollutant, the name of that com-
ponent must be marked on the package 
in parentheses in association with the 
marked proper shipping name. Where 

two or more components which make a 
material a marine pollutant are 
present, the names of at least two of 
the components most predominantly 
contributing to the marine pollutant 
designation must appear in parentheses 
in association with the marked proper 
shipping name; and 

(2) Except as otherwise provided in 

this subchapter, the MARINE POL-
LUTANT mark shall be placed in asso-
ciation with the hazard warning labels 
required by subpart E of this part or, in 
the absence of any labels, in associa-

name.

this subchapter, a bulk packaging that 
contains a marine pollutant must—

bottom if the packaging has a capacity 
of less than 3,785 L (1,000 gallons). The 
mark must be visible from the direc-

played in black lettering on a square- 
on-point configuration having the same 
outside dimensions as a placard; or

side with the MARINE POLLUTANT 
mark if the packaging has a capacity 
of 3,785 L (1,000 gallons) or more. The 
mark must be visible from the direc-
tion it faces. The mark may be dis-
played in black lettering on a square- 
on-point configuration having the same 
outside dimensions as a placard. 

(c) A transport vehicle or freight con-

tainer that contains a package subject 
to the marking requirements of para-
graph (a) or (b) of this section must be 
marked with the MARINE POLLUT-
ANT mark. The mark must appear on 
each side and each end of the transport 
vehicle or freight container, and must 
be visible from the direction it faces. 
This requirement may be met by the 
marking displayed on a freight con-
tainer or portable tank loaded on a 
motor vehicle or rail car. This mark 
may be displayed in black lettering on 
a white square-on-point configuration 
having the same outside dimensions as 
a placard.
