Pallet Grades Explained: A, B, and Reject/Core

Why Pallet Grading Exists

Used pallets are not commodities in the way a ton of scrap steel is. Two 48x40 pallets that look similar from across a warehouse can differ enormously in how many trips they have left, whether their deck boards will hold your product over a rack beam, and how much a buyer should pay. Grading is the industry's shorthand for sorting that variability into predictable, priceable tiers.

There is no single government-mandated grading scale for recycled pallets. Instead, the market converged on a practical vocabulary built around the Grocery Manufacturers Association (GMA) 48x40 hardwood pallet, the most common footprint in North America. When a broker quotes 'A grade 48x40s' or 'number two GMAs,' they are describing a well-understood condition band, not a legal certification.

Because grading is condition-based rather than certified, reputable recyclers publish their own criteria and inspect every incoming load. Grade drift, calling a #2 an #1 to shave a few cents, is the fastest way for a supplier to lose a customer, so consistency matters more than the label itself.

Grade A (#1): The Near-New Standard

A Grade A pallet, often written #1, is the top of the used market. It has all of its original deck boards, no cracked or missing stringers, no protruding nails, and typically no visible repairs. Many were used only a handful of times before being sold back into recovery, so they retain most of their structural life.

Grade A units are the right choice when the pallet is part of the customer experience or the automation: retail floor displays, big-box distribution centers with automated storage and retrieval systems (AS/RS), and any line where a jammed conveyor from a snagged board is expensive. Because supply is limited by how many good pallets are actually recovered, Grade A carries the highest price of any used tier.

• All original deck boards present, none split or missing
• Stringers uncracked and free of significant wear
• No plugs, companion boards, or added repair lumber
• Clean appearance, no protruding fasteners
• Full remaining trip life for retail or automated use

Grade B (#2): Sound but Repaired

Grade B, or #2, is the workhorse of the recycled pallet world. These pallets are fully functional and safe for standard shipping loads, but they show honest wear: a replaced deck board or two, plugged stringers where a cracked section was repaired with a nailed-on companion board, or mixed lumber from prior rebuilds. Structurally they are sound; cosmetically they are used.

Repairs are what separate B from A. A common fix is the 'companion' or 'scab' board, a supporting board nailed alongside a cracked stringer to restore load capacity. Another is deck board replacement, where a broken top or bottom board is swapped for a salvaged one. A well-repaired #2 can carry the same weight as a #1; it simply will not photograph as well on a retail floor.

For most internal warehouse transfers, freight to a distribution center, or shipments where appearance does not matter, Grade B delivers the best value. You pay meaningfully less than Grade A while retaining full functional capacity for typical loads.

Grade C, Reject, and Core Pallets

Below #2 sits a band of terms that overlap in practice: Grade C, reject, and core. A 'core' pallet is essentially raw material, a used pallet in unknown or broken condition, bought and sold by the truckload specifically to be sorted, repaired, or dismantled. 'Reject' means a pallet that failed inspection for resale as-is: a broken stringer, multiple missing deck boards, or damage that makes repair uneconomical relative to its value.

These pallets are not garbage; they are feedstock. Reject and core units flow into the remanufacturing and grinding streams described below. The economics hinge on yield: how many usable boards and stringers a recycler can salvage before the remainder is chipped. A load of cores is priced low precisely because the buyer is absorbing that sorting labor.

Remanufactured and Combo Pallets

A remanufactured pallet is built from the salvageable parts of reject and core pallets. Recyclers dismantle broken units, sort out the good deck boards and stringers, and reassemble them into a rebuilt pallet, sometimes to a custom size the original never was. These are also called 'remans' or, when they blend recovered and new lumber, 'combo' pallets.

Remanufactured pallets bridge a real gap in the market. They cost less than a brand-new pallet and often less than a clean Grade A, while offering a consistent, made-to-spec platform that unsorted #2s cannot guarantee. For a buyer who needs a repeatable size and known capacity on a budget, a good reman is frequently the smartest purchase on the lot.

The trade-off is that reman quality varies by builder. Because the inputs are recovered lumber, the fastener pattern, board thickness, and moisture content depend on the shop's standards. This is another reason to source from a recycler that grinds, repairs, and rebuilds under one roof rather than reselling anonymous loads.

How to Inspect a Load Before You Buy

You do not need to be a grader to spot the difference between a solid load and a problem one. Walk the stack and look at the parts that fail first. Stringers are the spine: check both long sides for cracks, especially at the notches and at the ends where forklift tines strike. A split that runs through a notch is a load-capacity failure waiting to happen, no matter how good the deck looks.

Then read the deck. Count for missing boards, look for splits that run with the grain, and press on end and lead boards, which take the most abuse and are the most common replacements. Run a hand along the top for protruding or backed-out nails, which snag product and tear operators' gloves. Finally, sight down the stack for consistency, a well-graded load looks uniform, while a mix of wildly different colors, thicknesses, and repair styles signals unsorted stock quoted above its real grade.

• Stringers: no cracks through notches or at the tine-strike ends
• Deck boards: none missing, no with-the-grain splits, tight to the stringers
• Lead and end boards: intact, since they fail first and are replaced most
• Fasteners: no protruding, bent, or backed-out nails on the deck surface
• Consistency: uniform color, thickness, and repair style across the load

How Grade Maps to Price and Use Case

Think of grade as a curve from appearance-and-life on one axis to price on the other. Grade A costs the most because good pallets are scarce and buyers pay for cosmetics and remaining trips. Grade B costs less and covers the bulk of everyday shipping. Remanufactured sits nearby, trading a rebuilt origin for a guaranteed size. Cores and rejects are cheapest because the buyer inherits the sorting.

The practical rule: never buy more grade than the job needs, and never buy less than it demands. Putting Grade A under a load bound for a landfill-adjacent one-way export is money burned; putting cores under a retail display is a jam and a damage claim waiting to happen. A good supplier will ask what the pallet is carrying and where it is going before quoting a grade.

A short field guide to matching grade to job: use Grade A for retail-facing displays, automated and AS/RS lines, and any shipment where appearance or jam-free handling is part of the deal. Use Grade B for internal transfers, general domestic freight, and one-way shipments where cosmetics do not matter. Use remanufactured when you need a repeatable custom size on a budget, and use cores only if you are set up to sort, repair, or dismantle them yourself.

• Grade A (#1): retail displays, automated/AS/RS lines, appearance-critical loads
• Grade B (#2): internal transfers, general and one-way domestic freight
• Remanufactured: budget-driven need for a consistent, made-to-spec size
• Core/reject: only for buyers who sort, repair, or dismantle in-house
