New gaylord boxes
Never filled, never stored wet. A new gaylord is the one grade that carries its full rating.

- Say "New" in the notes
A new gaylord has never carried a load. It keeps all of its rated strength, has no storage history to ask about, and is the grade to choose when a stack has to stand for months, when a place is damp, or when a customer asks for it. In Stack Check it keeps 100%, against 90% for Grade A.
What it looks like
Flat-packed or assembled from the maker; flaps square, no creases, no print but the maker's.
How high it stands
| Place | Share kept | 3-wall at 900 lb | Why |
|---|---|---|---|
| Heated warehouse | 100% | Do not stack | dry, steady air |
| Unheated dock | 65% | Do not stack | damp, cold air and swings in temperature |
| Trailer | 60% | Do not stack | condensation inside a closed box and a rough ride |
| Cooler | 55% | Do not stack | humid air, near the 90% level that halves board strength |
| Covered outdoors | 50% | Do not stack | humidity that can pass 85% to 90% |
Stack Check, 30 days under load. Share kept is grade times place.
A buyer who needs three high on a quarter-long stand is the buyer for new. Used boxes lose strength to every step in the table above; a new box loses only what place and time take.
A worked example
3‑wall New boxes at 900 lb a box, in a heated warehouse for 30 days, come out as "do not stack". Move the same boxes to a covered outdoor stack and the answer becomes "do not stack". The box did not change; the place did.
See the grades hub, new or used, the buy desk, the sell desk and recycling.
Why anyone buys new
New is for the cases where used does not fit: food-contact loads, medical product, a heavy load stacked high, or a customer who will not accept a used box. It is also the right answer when the supply of used boxes in the size you need is thin. The new-or-used guide walks through the choice.
