ECT vs Mullen — which spec do you actually care about?

Five things wrong with how warehouses store gaylords

Stacking too high. Storing outdoors uncovered. Ignoring humidity. Putting them on broken pallets. Mixing grades into the same stack. We've seen all five — sometimes at the same dock.

How to grade a gaylord box in 30 seconds

There are four tells that experienced yard crews use to put a grade on a box before the forklift even sets it down. None of them require tools, and most of them survive being explained to a brand-new hire.

1. Flap straightness

Open the top. Look down the four flaps. If they're flat and square, you're in A or B territory. If two flaps are bent past 15°, you're in C — fixable but not as-is. If three flaps are bent or one is torn off, you're recycling material.

2. Corner integrity

Run a thumb down each vertical corner. Crisp, no give = A. Slight crush, still rigid = B. Visible buckle = C. Anything that flexes more than half an inch when pressed = recycle.

3. Liner condition

Pull the liner halfway out. Clean and dry? You can keep it. Stained but intact? Replace the liner; box might still grade A. Soaked or torn liner with stained interior cardboard? You're at C or below.

4. The back-corner sniff

We're not joking. Mildew has a distinct smell that visual grading misses. If a back corner smells wrong, the inside of that wall has trapped moisture, and the strength rating is already gone. Recycle it.

That's it. Four checks, thirty seconds. The other 12 things we look at are refinements — these four catch the broad strokes every time.
