For the purposes of documentation and package marking:
If the material has a flash point at or above 38 °C (100 °F) and below 93 °C (200 °F), then the bulk packaging requirements of §173.241 of this subchapter are applicable. If the material has a flash point of less than 38 °C (100 °F), then the bulk packaging requirements of §173.242 of this subchapter are applicable.

When transported by highway, rail, or cargo vessel, waste Paint and Paint related material (UN1263; PG II and PG III), when in plastic or metal inner packagings of not more than 26.5 L (7 gallons),
are excepted from the marking requirements in Sec. 172.301(a) and (c) and the labeling requirements in Sec. 172.400(a), when further packed in the following specification and non-specification bulk outer packagings and under the following conditions:
- a. Primary receptacles must conform to the general packaging
requirements of subpart B of part 173 of this subchapter and may not
leak. If they do leak, they must be overpacked in packagings conforming
to the specification requirements of part 178 of this subchapter or in
salvage packagings conforming to the requirements in Sec. 173.12 of
- b. Primary receptacles must be further packed in non-specification
bulk outer packagings such as cubic yard boxes, plastic rigid-wall bulk
containers, dump trailers, and roll-off containers. Bulk outer
packagings must be liquid tight through design or by the use of lining
- c. Primary receptacles may also be further packed in specification
bulk outer packagings. Authorized specification bulk outer packagings
are UN11G fiberboard intermediate bulk containers (IBC) and UN13H4
woven plastic, coated and with liner flexible intermediate bulk
containers (FIBCs) meeting the Packing Group II performance level and
lined with a plastic liner of at least 6 mil thickness.
- d. All inner packagings placed inside bulk outer packagings must be
blocked and braced to prevent movement during transportation that could
cause the container to open or fall over. Specification IBCs and FIBCs
