IBCs that previously contained hazardous materials (identified by a UN number and hazard diamond label) must be "drip dry," and free of residue. All IBCs must display proper labeling in accordance with U.S. Department of Transportation (DOT) regulations. Per DOT 49 CFR §173.29, all openings must be securely closed, including valves, lids, and bung plugs.
IBCs containing excess hazardous material residue will be rejected and returned at the shipper's expense. IBCs with excess non-hazardous residue will incur a disposal fee of $25.00 per gallon, payable immediately.
All IBCs must be in reusable condition. Non-reusable units will be subject to freight and disposal charges. To be considered reusable, an IBC must have: an intact, non-crushed pallet base (metal or plastic only; wood pallets are not accepted) and a metal cage that is not bent and free of corrosion.
IBCs that previously contained "P-listed" hazardous waste or materials included on the EPA List of Lists must be triple-rinsed. All labels must be removed and the container must be clearly marked as "triple rinsed."
