Ammonia solution, relative density between 0.880 and 0.957 at 15 degrees C in water, with more than 10 percent but not more than 35 percent ammonia
What this means
Ammonia solution, relative density between 0.880 and 0.957 at 15 degrees C in water, with more than 10 percent but not more than 35 percent ammonia appears on the federal Hazardous Materials Table (49 CFR §172.101), the table that governs how a material must be classified, packaged, and labeled for transport.

Special provisions (§172.102)
336 — The use of UN1H1 drums, UN3H1 jerricans, and UN6HA1 composite packagings which meet the requirements of part 178 of the HMR at the Packing Group I or II performance level. These packagings are not required to: (1.) meet the venting requirements in § 173.24(g) or (2.) be marked with the hydrostatic pressure test marking specified in § 173.24a(b)(4). Shipment of packages under this special provision must be made by private or contract motor carrier. Transportation of these packages also requires the door of each van trailer to be marked with “Warning trailer may contain chemical vapor. Do not enter until vapors have dissipated.” The driver of the transport vehicle and the consignee(s) must be trained not to enter the transport vehicle until the ammonia vapors have dissipated, and the emergency response information on the shipping paper must indicate that the vehicle contains ammonia vapors. This training must be documented in training records required by § 172.704(d). Transport vehicles must be vented to prevent accumulation of vapors at a poisonous or flammable concentration.
