Publishing our grade criteria, and why that was uncomfortable

There was a real argument internally about this. Publishing a number means you have to hit it every time, including on the Friday when the load has to go.

Every article here came out of a real conversation. Start one — a coordinator answers, not a bot.

We reply here — no phone line exists at this company.

Whole units. An estimate is fine.

01The internal argument

When we decided to publish numeric grade criteria on the website, the objection from the yard was not about honesty. It was about Friday afternoons.

Every yard has a version of this. A load has to ship. There are 480 good pallets and 20 that are borderline — a companion stringer here, a third replaced board there. In a world of unpublished criteria, those 20 go on the truck and nobody ever knows. In a world of published criteria, they do not, and either the load goes short or somebody stays late.

That is the actual cost of transparency in this business. Not embarrassment — yield and flexibility.

Nothing there is remarkable. What is unusual is that it is numeric and public, so a customer can hold us to it and a grader cannot argue with it.

03What changed afterwards

  • Grade A yield fell by roughly four percentage points in the first quarter. That is the drift we had accumulated, made visible.
  • Grade B volume rose correspondingly, and B sells perfectly well.
  • Disputes dropped sharply. An argument about whether a pallet is Grade A becomes a measurement rather than an opinion.
  • Customers started inspecting more, which we expected and which turned out to be a benefit — they tell us within a day when something drifts.
  • Our reject rate on repeat accounts settled under 0.4%.

04What to ask your own supplier

  1. Ask for their grade criteria in writing. Not a description — the document.
  2. Check whether it contains numbers. 'Minimal repairs' is not a criterion.
  3. Ask what their inspection and rejection protocol is. If there is none, the criteria are decorative.
  4. Ask who grades — the same person at intake and exit, or two people?
  5. Ask what happens to a pallet that fails twice.

The answers tell you a great deal, and so does the speed with which they arrive. A yard that has these documents ready is a yard that has thought about them. More on how the vocabulary works in grades explained, and on why definitions drift in an earlier piece.

Vocabulary

Terms this article uses

Pulled from the text automatically and defined the way the trade uses them.
Companion stringer
A second stringer nailed alongside a cracked original during repair. Structurally sound, adds 3–5 lb, and disqualifies a pallet from Grade A.
Deck board
Any of the boards forming the top or bottom face of a pallet. Typically 5.5 inches wide and 0.5–0.75 inches thick.
Grade A
Our top recycled tier: no companion stringers, two or fewer replaced deck boards, one plug maximum, squareness within 0.5 inch.
Grade B
Companion stringers permitted, up to five replaced boards, up to three plugs, squareness within 0.75 inch. The most commonly traded recycled grade.
Grade C
Structurally sound but cosmetically rough. Suitable for floor-stacked storage and one-way freight; never for racking.
Mend plate
A metal plate fastened across a split stringer. A repair of last resort; disqualifies a pallet from Grade A and usually from Grade B.
Plug
A wooden insert fitted into a broken notch to restore stringer material. One is permitted in Grade A; three in Grade B.
Stringer
The board set on edge that separates the top and bottom decks of a stringer pallet. Usually 1.5 x 3.5 inches nominal.

How we grade: ninety seconds inside the sort line

Four seconds to sort, ninety seconds to repair, four seconds to check. Here is what happens in each of them, and why the last four seconds are the most important.
