Dear Ms. Clemenson:
This is in response to your letter dated October 30, 2002, requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you request information on the
shipping paper, packaging, hazard communication, and loading requirements for a material described as
"Environmentally hazardous substance, solid, n.o.s., 9, UN 3077, III" transported in 50 pound bags,
2,000 pound bags, and 25-35 ton bulk trucks.
As provided by § 172.504(Đ(9), when transported domestically a CLASS 9 placard is not required to
be displayed on a transport vehicle containing packages of a Class 9 material (e.g., bags, IBCs or
dry-bulk trailer). Each non-bulk packaging, unless otherwise excepted, must be marked in accordance
with Part 172, Subpart D and labeled in accordance with Part 172, Subpart E. Bulk packagings
containing a Class 9 material must be marked with the appropriate identification number displayed on a
CLASS 9 placard, an orange panel, or a white square-on-point display configuration.
For a material properly described as "Environmentally hazardous substance, solid, n.o.s., 9, UN 3077,
II" the bulk and non-bulk packaging requirements are found in §$ 173.240 and 173.213, respectively.
The shipping paper requirements are found in Part 172, Subpart C and, for transportation by highway,
the loading and unloading requirements are located in Part 177, Subpart B.
I hope this satisfies your request.
Sincerely,
Office of Hazardous Materials Standards

Mr. Mazzullo:
Bay Zinc Company manufactures Zinc Sulfate fertilizer. We currently ship in 50# bags,
2000# bags, and in 25-35 ton bulk form. We have been placarding our 2000# bags and
bulk trucks for the last 8 years under the Misc. Placard Class 9 UN 3077. We were under
the understanding that anything over the portable quantity of 10001b of Zinc Sulfate per.
container needed to be placarded. We have been making sure every load that is shipped
the truck driver has his hazardous endorsement. Jessica in the Hazmat information
out of our facility has a placard on all sides of the truck or railcar, and we make sure that
be placarded. However, the container or bags need the correct classification number on
department (800) 467-4922 informed me that the miscellaneous class: 9 does not need to
the container or bags.
I also talked to a gentlemen, in the Motor Carrier department (202) 366-0647 about the
truck drivers needing a hazardous endorsement on their license to haw our Zinc Sulfate
product. He mentioned that as long as the product is correctly identified on the container
or bags and not placarded, the drivers do not need a hazardous endorsement on their
license.
I need a letter from your office that states what the regulations are regarding paperwork,
packaging, loading, and transporting of our Zinc Sulfate fertilizer in 5,0# bags, Z000#
please it me know whori work need to contact Thanks for your nep in this meter.
Sincerely,
anner clemenson
