There is no national grading authority for used IBCs, which means 'Grade A' in a bid document is legally meaningless. A specification has to describe the container, not name a letter, or you will receive exactly what the cheapest bidder decides the letter means.
The eight clauses worth writing
- Construction and marking: 'Composite IBC, UN design type 31HA1, packing group Y or better, marking fully legible and photographed at the time of quote.' This single clause eliminates most of the bad end of the market.
- Capacity and footprint, with the tolerance you can actually accept: '275 US gallon nominal, 48 × 40 in footprint, overall height not exceeding 48 in.'
- Bottle condition, described rather than graded: 'No stress whitening or crazing at corners or sump; no deformation of the sump seat; walls free of bulging; staining permitted.'
- Cleaning: 'Triple-rinsed minimum, with a cleaning record stating cycle type, temperature, duration and operator. Food contact requires a potable final rinse and a laboratory verification result.'
- Last contents: 'Documented last-contents declaration naming product and concentration. Containers with undocumented history are not acceptable.'
- Hardware: '2 in outlet valve, EPDM seat, new or verified-functional; 6 in buttress cap, vented or solid as specified; new gaskets throughout.'
- Pallet: specify the type and why. 'Composite or full steel pallet; wood pallets not acceptable' is a legitimate requirement in a washdown environment.
- Remedy: 'Containers not meeting this specification on delivery shall be replaced or credited at the supplier's cost, without requiring an inspection report from the purchaser.'
