The single most important document in any reused-IBC purchase is the prior-contents declaration, ideally supported by the Safety Data Sheet for whatever product the tote previously held. Buyers ask for it about 40 percent of the time in our experience, which means 60 percent of buyers are taking a chemical-compatibility risk they could have eliminated with one extra sentence in the order email. The fix is essentially free and we have copy-pastable language to suggest.
The minimum ask
When sending an order request, include this sentence: "Please send the prior-contents declaration and any available SDS for the lot you plan to ship, before we confirm the order." Any seller running a legitimate operation will produce this within one business day. A seller who hedges, delays, or sends back vague category descriptions is not running the kind of operation a careful buyer wants to do business with.
What the document should contain
A useful prior-contents declaration names the specific product, the original shipper, the original ship date or wash-receive date, and a reference number tying the declaration to the specific tote serial. An SDS adds the chemical composition, hazard rating, and recommended handling. Together they let the buyer confirm chemical compatibility with their intended use before the unit leaves the seller's yard.
- Specific prior product, not a category
- Original shipper or chain-of-custody reference
- Original receive date at the reconditioner
- Tote serial or lot number tying paper to physical unit
- SDS for the prior product where available
What to do when paperwork is missing
If a seller cannot produce a prior-contents declaration on request, the only defensible response is to assume worst-case prior contents and grade the tote down accordingly — secondary use only, non-contact, non-consumed. Many small resellers genuinely cannot produce paperwork because they bought from a broker who bought from another broker and the chain broke. That is not the buyer's problem to fix. Walk away or grade down and price accordingly.
