Every couple of months a customer asks if we can take a load of Gaylord boxes that previously held a Class 4–9 hazardous material — flammable liquids, oxidizers, toxic substances, corrosives, that family. The answer is always no. Here is the why and the referral.
Why we say no
Handling hazmat-residue containers requires specific licenses, training, and procedural controls we do not maintain. The economics of maintaining those licenses do not work at our volume of hazmat-adjacent material, which is fortunately small.
More importantly, the risk of cross-contamination on our floor is real. If a Gaylord that previously held a Class 8 corrosive ends up in our regrade pile, it can contaminate adjacent boxes that we then ship to a food-grade customer. The downstream consequences are unacceptable.
How we screen
Every inbound load includes a prior-contents declaration. If the declaration includes any hazmat classification, the load gets rejected at intake and the trailer goes elsewhere. If the declaration is vague or unverifiable, we either request more documentation or reject preemptively.
Most of the time, the customer has not handled hazmat — they just shipped some boxes from a customer of theirs and do not know the prior contents. We help them figure it out. About 90% of the time the boxes turn out to be safe to handle.
Who to call instead
We work with two regional hazmat-licensed packaging recyclers we are happy to refer you to. They handle Class 4–9 residue containers under their EPA RCRA permits, and they can ship to specialized treatment facilities. The economics are different — the cost is higher and the per-box net is negative — but the regulatory path is clean.
