Packaging & Logistics
Shipping Description (US DOT)
UN1915, Cyclohexanone, 3, PG III
Packaging-dependent regulation: Non-bulk packaging (≤ 119 gal, e.g. drums, pails, cans) ships as NON-REGULATED under the combustible-liquid reclassification (49 CFR 173.150(f)). Bulk packaging (totes/IBC > 119 gal) ships fully regulated under the DOT profile shown above. The combustible-liquid reclassification does not apply to transportation by vessel or aircraft, except where other means of transportation is impracticable (49 CFR 173.120(b)(2)).
Sourced from 49 CFR 172.101. Confirm against shipping documents and carrier requirements before tender.
