lieu of the EX-number required by paragraph (a) of this section, with a 

national stock number issued by the Department of Defense or identifying 

information, such as a product code required by regulations for 

commercial explosives specified in 27 CFR part 55, if the national stock 

number or identifying information can be specifically associated with 

the EX-number assigned.
