The uncomfortable truth about pallet grades
If you call five pallet yards in one afternoon and ask for a quote on Grade A 48×40 recycled pallets, you will get five different products at five different prices. This is not a conspiracy. It is the predictable result of an industry that grew out of scrap hauling and never agreed on a dictionary.
There is no government body that certifies pallet grades. There are useful industry references — the Pallet Design System from Virginia Tech, the NWPCA's uniform standards, the various GMA specifications — but none of them are enforced on a used pallet changing hands between two private companies. What you actually buy is whatever the seller's definition happens to be, backed by whatever the seller's reputation is worth.
Our Grade A, written out completely
A Grade A 48×40 stringer pallet leaving our yard has seven top deck boards and five bottom deck boards, all original width, none plugged, none cracked through at a nail line. Three stringers, solid, no companions, no plating. Overall dimensions within a quarter inch of 48 by 40. Squareness within a quarter inch measured corner to corner. No protruding nails on either deck. No visible mould or staining beyond ordinary weathering. Rated 2,800 lb dynamic and 2,200 lb racked.
That last sentence is the expensive part. Publishing a racked load rating means we own the consequence if the pallet deflects in your beam rack. Most sellers avoid publishing one at all. We decided early that if a customer is going to put product above head height on our wood, they deserve a number they can plan around.
What a companion stringer is, and why it is not a defect
When a stringer cracks, the standard repair is a companion: a second piece of timber nailed alongside the damaged one, spanning the crack and restoring the load path. Done properly, with kiln-dried stock and helical nails, a companion-repaired stringer is frequently stiffer than the original.
We still grade companion-repaired pallets as B rather than A, because the pallet is visibly repaired and because the deck height can shift by an eighth of an inch. That matters on automated conveyor lines and matters not at all in a hand-loaded truck. If your operation is the second kind, buying B instead of A is the easiest 20% saving in your packaging budget.
Grade B, Grade C and the honest conversation
Grade B is an honest working pallet. Plugs are allowed — a plug is a short piece of deck board let into a damaged area — along with one companion stringer and six top boards instead of seven. Rated 2,200 lb dynamic, 1,500 lb racked. For most floor-stacked freight inside a closed loop, this is the correct purchase and the money saved is real.
Grade C is not a pallet we sell for carrying freight. It is core: material destined for the de-nailer, from which clear boards become repair stock and the rest becomes shavings, mulch and biomass fuel. If somebody quotes you an unusually low price on A-grade pallets, what you are probably buying is a well-presented C.
How to protect yourself from grade drift
Ask for the specification in writing before the first order. Any serious yard will have one. Then measure one in ten pallets on the first three deliveries: tape measure on both dimensions, steel square in two corners, flip one over and look at the bottom boards. It takes eleven minutes and it sets the tone for the entire relationship.
If something fails, write it on the delivery ticket rather than calling. A written record of a rejected unit is the only thing that reliably changes supplier behaviour. We replace rejected units on the next route with no restocking fee, and we would rather hear about four bad pallets today than lose an account in six months.
