Pallet Grades Explained: GMA Grade A vs B vs C
Grade A, B, and C criteria, retailer requirements, cost analysis, and supplier verification checklist. Florida Pallet Supply delivers new, recycled, custom, and ISPM-15 heat-treated pallets to all 67 Florida counties, with same-day dispatch from its Tampa, Orlando, Jacksonville, Miami, and Lakeland yards and a 50-pallet minimum order.
Quick answer: Pallet grades rate used 48x40 GMA pallets by condition. Grade A (also called #1) pallets have no repaired stringers and intact deck boards, so they suit retail and racking. Grade B (#2) pallets may have one or two repaired stringers and suit one-way shipping. Grade C covers heavier repairs and mixed boards for low-risk internal use.
Pallet grading is the most important factor in sourcing decisions for operations managers and supply chain professionals -- and one of the most inconsistently applied standards in the industry. "Grade A" means different things at different suppliers. This guide defines the GMA and industry-standard pallet grading criteria, explains what each grade looks like in practice, specifies which applications require which grade, and gives you the questions to ask any supplier to verify they are grading correctly before you buy.

The Grocery Manufacturers Association (GMA) developed the pallet grading system that is now used across the US pallet industry. Three grades cover the full spectrum from near-new to marginal condition.
Grade A Near-New / Premium Recycled
Grade A pallets are structurally sound with no broken boards, no missing deckboards, and no cracked or broken stringers or blocks. Deckboards may show minor surface weathering or staining but must be full-width with no splits compromising load-bearing capacity. Notches (for stringer pallets) must be clean and undamaged. No protruding nails or staples. No chemical odor. No mold or mildew. Grade A pallets are accepted by virtually all major retailers including Walmart, Kroger, Costco, Whole Foods, Amazon FBA, and Home Depot. They are required for all food-grade and pharmaceutical GDP applications.
Grade B Usable / Repaired Condition
Grade B pallets have minor structural repairs -- one or two replaced deckboards, repaired stringers, or minor surface damage that does not compromise load capacity. A Grade B pallet can safely carry its rated load but shows visible evidence of prior use and repair. Minor cracks, weathering, and staining are acceptable. Missing deckboards are NOT acceptable even for Grade B -- all boards must be present and load-bearing. Grade B pallets are suitable for internal warehouse use, non-retailer shipments, agricultural product support, and construction material handling. Most major retailers do not accept Grade B for inbound shipments.
Grade C Marginal / End-of-Life
Grade C pallets have significant structural damage -- multiple broken or missing boards, cracked stringers, or blocks with major damage. They may still support light loads in static storage but are not safe for dynamic forklift or pallet jack use. Grade C pallets are appropriate only for one-time light-duty use, blocking/bracing, or recycling/chipping. They should never be used for outbound shipments to customers and should not be used under loads heavier than a few hundred pounds. Many operations use Grade C pallets as waste/firewood or shred them for mulch.
Grade A Inspection Criteria: The Full Checklist
These are the criteria Florida Pallet Supply applies to every pallet before grading it Grade A:
All top deckboards present -- no missing boards
All bottom deckboards present -- no missing boards
No broken top deckboards (splits extending full width or separating from fastener)
No broken bottom deckboards
Both stringers intact -- no cracks through full stringer depth
Stringer notches undamaged and clear (for stringer pallets)
All blocks present and not cracked through (for block pallets)
No protruding nails, staples, or metal fasteners on any surface
No chemical, fuel, mold, or food-contamination odor
No MB (methyl bromide) treatment stamp on either stringer
No visible mold or mildew growth
Pallet lies flat -- no bow or twist exceeding 1 inch across the 48-inch span
No delamination of engineered wood components (LVL stringers)

Why Grade A Recycled Beats Grade B Every Time for Retailer Shipments
The cost difference between Grade A recycled and Grade B recycled is typically $3-6 per pallet. A single Walmart chargeback for a non-compliant pallet is typically 3% of the invoice value -- on a $10,000 invoice, that is $300. The math makes Grade A the obvious choice for every retailer shipment:

The most expensive pallet decision you can make is using Grade B pallets on retailer lanes to save roughly $2 to $6 per pallet. One chargeback or load refusal undoes months of "savings." Use Grade A for all outbound shipments and Grade B only for internal movements.
What Actually Downgrades a Pallet: Defect-to-Grade Rubric
Grade names are only useful if you know which physical defects move a pallet from one grade to the next. There is no single national body that certifies pallet grades, so rubrics vary between recyclers. That is precisely why buyers get burned: two suppliers can both sell you "Grade B" and ship visibly different pallets. Below is the defect-by-defect rubric we grade against, which follows common recycled-pallet practice. Use it as the checklist when you audit any supplier. Assessed July 2026.

ⓘ Grading is not federally standardized. Ask any supplier to put its rubric in writing before you order, and inspect against it on the first two loads. See our receiving inspection checklist.
How to Verify Your Supplier's Grading Standards
Ask any pallet supplier these questions before placing an order:
What is your written Grade A specification? Can you provide it in writing?
Do you allow any broken deckboards in Grade A? (The answer should be: No)
Do you allow missing deckboards in Grade A? (The answer should be: No)
How do you handle borderline pallets -- do they get downgraded to Grade B or repaired to Grade A?
Can I see a sample of your Grade A inventory before ordering?
What is your return/replacement policy if Grade A pallets arrive not meeting spec?
Do you sort by grade at your facility or rely on driver grading at delivery?
Florida Pallet Supply maintains a written Grade A specification and grades all pallets at our facility before delivery. We accept returns on any pallet that does not meet the grade specified at time of order.
Use this chart to compare GMA pallet grades at a glance. Grading is not federally standardized, so always confirm how your supplier defines each grade.

What Is a GMA Pallet?
A GMA pallet is the 48 x 40 inch wood stringer pallet standardized by the Grocery Manufacturers Association, the trade group now known as the Consumer Brands Association. It uses three stringers with notches that allow partial four-way forklift entry, and it is the most common pallet in North American grocery and retail supply chains. When buyers search for "GMA Grade A," they mean a 48x40 GMA pallet in the top condition grade.
Grade also changes how much weight a pallet can safely carry: a Grade B pallet should be derated compared with Grade A. See our pallet load capacity guide for capacity by grade. Florida Pallet Supply grades every recycled load, is an NWPCA member, and dispatches same day from Tampa, Orlando, Jacksonville, Miami and Lakeland.

Frequently Asked Questions
The main downgrade triggers are repaired or companion stringers, split boards, plugs and patches on the deck, and staining. Grade A allows no repaired stringers, no missing deck boards, and no splits through the nail line. Grade B typically permits one to two repaired stringers, minor splits that do not cross the nail line, and flush patches. Grade C permits three or more repaired stringers, mismatched replacement boards, and heavier weathering. Some conditions are a reject at every grade: protruding nails, chemical or oil staining, soaked wood, active mold on a food or retail lane, and any stringer cracked through at a fork entry. Pallet grading is not federally standardized, so ask your supplier for its written rubric.
The GMA system defines Grade A as the highest grade. Some suppliers use terms like 'Grade A+', 'Premium Grade A', or 'Select Grade A' to describe their highest-quality recycled pallets -- those closest to new condition. These are marketing terms, not industry-standard grades. When evaluating a supplier who uses these terms, ask for the specific criteria -- what they call Grade A+ should at minimum meet the standard Grade A criteria, and the distinction is typically about cosmetic appearance (less staining, lighter wear) rather than structural differences.
A Grade A recycled GMA 48x40 stringer pallet used in typical distribution service has a remaining life expectancy of 12-36 additional trips depending on load weights, handling care, and whether it is in an open or closed loop. Pallets used in closed-loop operations (returned each time) can achieve 50+ total trips before reaching Grade C. Open-loop operations (pallets lost at customers) see whatever trips remain before the pallet is lost. Plan to budget 12-15% annual pallet replacement cost for open-loop operations using Grade A recycled pallets.
Yes -- that is exactly what pallet repair operations do. A Grade B pallet with a broken deckboard can be repaired by replacing that board with new or salvage wood, returning it to Grade A structural status. The economics of repair depend on labor costs vs. the Grade A vs. Grade B price differential. Florida Pallet Supply maintains a pallet repair program to keep Grade A inventory levels high. Repaired pallets that meet Grade A criteria are sold as Grade A recycled -- there is no separate 'repaired' grade in the standard system.
The National Wooden Pallet and Container Association (NWPCA) publishes the Uniform Standard for Wood Pallets, which provides more detailed specifications than the GMA grading system. The NWPCA standard includes specifications for new pallet construction (board dimensions, fastener requirements, wood species) as well as definitions for recycled pallet quality. In practice, the GMA A/B/C grading shorthand is more commonly used in the field. For formal procurement contracts, some large buyers reference the NWPCA standard for new pallet specifications and GMA grades for recycled pallets.
OSHA 29 CFR 1910.176 requires that storage areas be maintained in good order and that pallets not be a hazard. Using Grade C pallets under dynamic forklift loads -- particularly loads near the pallet's rated capacity -- creates OSHA-citable hazards. Grade B pallets under appropriate loads are generally OSHA-compliant but should be inspected before use. Grade A pallets fully comply with OSHA material handling requirements when used within rated load limits. Document your pallet inspection program to demonstrate compliance during OSHA audits.
The difference is repairs and condition. A Grade A pallet has no repaired or companion stringers, no missing deck boards and no splits through the nail line, so it looks and performs close to new. A Grade B pallet can have one or two repaired or plated stringers, minor splits and flush patches. Grade A is the safer choice for retailer shipments and racking; Grade B costs less and works well for one-way shipping and internal moves.
GMA stands for Grocery Manufacturers Association, the trade group that standardized the 48 x 40 inch wood stringer pallet used across grocery and retail distribution. The group now operates as the Consumer Brands Association, but the pallet is still called a GMA pallet. "GMA Grade A" means a 48x40 GMA pallet in the best recycled condition grade.
For most one-way and open-loop shipments, yes. Grade B pallets are structurally sound but show repairs, so they are a good value when the pallet will not come back and the receiver does not require Grade A. Check your customer routing guide first: many retail distribution centers specify Grade A or better, and a rejected load costs more than the savings. Grade B should also be derated for racking.
