- Who usually buys it
- Staging in heated rooms, device and electronics sites, steady users who want a repeatable spec.

- Say "Grade A" in the notes
Grade A is the used grade closest to new. A Grade A box was filled once, stayed dry, and shows no creasing that weakens the walls.
What it looks like
Clean, dry board; sharp corners; flaps flat and uncracked; the bottom sound. Light scuffs and old shipping labels are allowed.
How high it stands
| Place | Share kept | 3-wall at 700 lb | Why |
|---|---|---|---|
| Heated warehouse | 90% | Two high | dry, steady air |
| Unheated dock | 59% | Do not stack | damp, cold air and swings in temperature |
| Trailer | 54% | Do not stack | condensation inside a closed box and a rough ride |
| Cooler | 50% | Do not stack | humid air, near the 90% level that halves board strength |
| Covered outdoors | 45% | Do not stack | humidity that can pass 85% to 90% |
Stack Check, 30 days under load. Share kept is grade times place.
A Grade A box in a heated room keeps nearly all of its rating. The same box on an unheated dock loses a third more to place, which is a bigger cut than the grade itself.
A worked example
3‑wall Grade A boxes at 700 lb a box, in a heated warehouse for 30 days, come out as "two high". Move the same boxes to a covered outdoor stack and the answer becomes "do not stack". The box did not change; the place did.

Where Grade A earns its price
Grade A is the grade to ask for when the box matters more than the money: a heavy load, a tall stack, a box that touches a clean product, or a delivery to a customer who looks at the boxes. It is a poor choice for a box that goes straight to scrap or to a wet dock, where its extra strength is spent for nothing.
