Other Regulated Materials ORM

In general, a material corresponding to the Other Regulated Material (ORM) hazard class is a material that may pose an unreasonable risk to health and safety or property when transported in commerce and that does not meet the definition of any other hazard class. Consumer commodities, as will be seen later, are an exception. 

There are five classes of ORM materials, A through E, as follows  

Materials classified as ORM-A are commonly regulated for air shipment only, unless they are also hazardous substances or hazardous wastes (see ORM-E). 

Dilute hypochlorite solutions, stannous chloride solid, etc., are ORM-B materials. 

A hazardous waste, as defined by DOT, means any material subject to the hazardous waiste manifest requirements of the EPA specified in 40CFR Part 262 (49CFR 172.8 and Classification Under RCRA later in this chapter).
