If you have ever bought used Gaylord boxes from more than one vendor, you have probably had the experience of paying for "Grade B" and getting something that did not look like the last Grade B you bought. The trade has no industry-wide standard. Each yard defines it. Here is the eight-question screen we recommend.
1 · How many trips has the box taken before this one?
For our Grade B, the answer is two or three. Some yards call a four-trip box Grade B. Ours is C by that point. Ask in writing.
2 · What is the wall condition?
For Grade B, walls should be structurally intact with no compression at corners. Light bulges below the top edge are acceptable. Compression visible at any corner pulls the box to Grade C in our rubric.
3 · What is the outer-liner cosmetic condition?
Grade B tolerates light scuffing and minor label residue. A single repair tape patch is acceptable; two patches on adjacent faces is a downgrade.
4 · Is the pallet attached and what condition is it?
Grade B paired with a sound pallet should ride a forklift without complaint. If the pallet has more than two replaced boards or any cracked stringer, the package is downgraded, even if the box itself is clean.
5 · Is the lid present?
Grade B can ship lidded or open-top. Lidded is preferable for multi-trip applications. Open-top Grade B is fine for single-trip industrial.
6 · What was declared prior contents?
This is the question that separates serious vendors from brokers. A Grade B inbound declaration should specify what the box held last. "Various consumer goods" is not a declaration. "Dry pet food, single trip, sealed liner" is.
7 · What is the vendor's return policy if the load misses spec?
Ours is five business days. Vendor varies. A vendor that hesitates on this question is telling you something.
8 · Can the vendor show you photos of the actual pallets before shipment?
If the answer is no, ask why. We photograph every outbound BOL. Most reputable yards do.
The point of this checklist is not to suggest you should distrust every vendor. It is that a defensible answer to all eight questions, in writing, is how you avoid the small but expensive lottery of buying used corrugate sight unseen.
