Three Commonly Described Grades
Recycled pallets are commonly described as Grade A, B, or C based on the condition of the deck boards, stringers or blocks, fasteners, and overall dimensions. There is no single legal grade definition, so ask the supplier what a grade means before you order. The descriptions below are the common ones.
Grade A — Premium
Often the highest-cost recycled grade
Grade A pallets are commonly described as being in like-new or lightly used condition with no significant repairs. They tend to have uniform dimensions, clean surfaces, and consistent board spacing. These pallets are generally the top tier of recycled pallets, visually clean and close to new in appearance.
View full Grade A detailsGrading Criteria
- No broken or missing boards
- No major staining, mold, or contamination
- Boards tightly fastened with no protruding nails
- Stringers or blocks free of cracks and splits
- Dimensions close to spec
- Few or no previous board replacements or repairs
Best Used For
- •Automated warehouse systems (AS/RS)
- •Applications with strict cleanliness requirements

Grade B — Standard
Often costs less than Grade A
Grade B pallets are commonly described as structurally sound but showing moderate signs of use. They may have one or two repaired boards, minor surface staining, or cosmetic imperfections. Grade B is widely used in the recycled pallet market and often costs less than Grade A or new pallets.
View full Grade B detailsGrading Criteria
- A small number of repaired or replaced deck boards
- Minor surface staining or discoloration
- All boards structurally sound and securely fastened
- Stringers may have minor notch damage (not structural)
- Dimensions reasonably close to spec
- No broken stringers or blocks
Best Used For
- •General warehousing and distribution

- •Cost-conscious operations with manual handling
Grade C — Economy
Often the lowest-cost grade
Grade C pallets are commonly described as functional but showing significant signs of use and repair. They may have multiple replaced boards, visible staining, and cosmetic wear. While often not suitable for automated systems or premium applications, Grade C pallets are commonly used for one-way shipments, temporary storage, and any application where appearance is secondary to function.
View full Grade C detailsGrading Criteria
- Multiple repaired or replaced boards
- Visible staining, weathering, and cosmetic wear
- Repairs should be structurally sound
- Stringers may have repaired cracks (with companion boards)
- Dimensions may vary more from spec
- Should support the intended load
Best Used For
- •One-way shipments (no return expected)
- •Temporary outdoor storage
- •Construction sites and job sites
- •Export loads where pallets stay at destination
- •Cost-sensitive applications
What to Check When Judging Pallet Condition
Whatever grade you choose, the same three areas tell you most about a pallet's condition: deck boards, stringers or blocks, and overall structural integrity. Use this list to check pallets when they arrive.
Deck Boards (Top & Bottom)
- Check for cracks, splits, and broken boards
- Verify all boards are securely fastened
- Inspect for protruding or missing nails
- Look for excessive staining, mold, or contamination
- Check board thickness (commonly 5/8" to 3/4")
Stringers or Blocks
- Inspect for cracks, especially around notches
- Verify stringers are straight and not warped
- Check for rot, insect damage, or soft spots
- Confirm notch dimensions allow proper fork entry
- Ensure blocks are securely attached (block pallets)
Overall Structure
- Test for racking (twisting or skewing)
- Verify dimensional accuracy with a tape measure
- Check that the pallet sits flat on a level surface
- Confirm weight capacity rating matches application (typical; confirm with the supplier)
- Look for the ISPM 15 / IPPC mark if needed for export

Typical Condition by Grade
There is no single legal definition of Grade A, B, or C, so the details vary from supplier to supplier. These are commonly described characteristics for each grade. Understanding them helps you check quality on delivery and communicate your requirements precisely when you request a quote.
Grade A — Premium: Commonly Described Condition
Nail Condition
No protruding nails. Nail heads flush with or below the board surface, with no bent, missing, or corroded nails. Helical or ring-shank nails are commonly preferred over smooth-shank nails.
Board Gaps
Top deck board spacing is uniform and consistent across the pallet width, close to the design specification. Bottom boards are evenly spaced with no visible misalignment.
Stains & Contamination
No oil stains, chemical stains, food residue, grease marks, or dark water stains. Minor surface discoloration from natural weathering (light graying) is generally acceptable if it does not indicate mold or rot. No evidence of mold, mildew, or fungal growth.
Repairs
Few or no previous repairs. Boards are mostly original, without companion stringers or replaced deck boards. Pallets with visible repairs are more commonly described as Grade B.
Board Condition
No cracks, splits, or broken boards. Few or no large knot holes, and little wane (bark edge). No soft spots, rot, or insect damage. Board edges are clean without excessive splintering.
Dimensional Accuracy
Overall length and width close to the nominal specification, with consistent board thickness. The pallet sits flat on a level surface without rocking.
Stringer/Block Integrity
Stringers are straight with no visible cracking, especially around notches. No crush damage at fork-entry points. On block pallets, all blocks are firmly attached with no looseness.
Grade B — Standard: Commonly Described Condition
Nail Condition
Nails are flush or nearly flush, with no protruding nails that could snag or injure. Missing nails are replaced. Minor surface rust on nail heads is generally acceptable.
Board Gaps
Deck board spacing may vary somewhat from the design specification. Board alignment does not need to be perfectly uniform, but boards should be roughly parallel.
Stains & Contamination
Minor surface staining from water, dirt, or ground contact is generally acceptable. No oil, chemical, or food contamination. Light mold staining (surface discoloration only) may be acceptable if the wood is structurally sound and dry. No active mold growth.
Repairs
A small number of replaced deck boards is common, ideally matching the originals in width and thickness and properly fastened. Companion stringers may be present if firmly attached and structurally sound.
Board Condition
Minor end-splits and small knot holes may be present if they do not compromise board strength. Light surface checking (hairline cracks from drying) is normal. No broken boards.
Dimensional Accuracy
Overall length and width reasonably close to nominal. Minor warping of individual boards may be acceptable if the pallet sits flat without excessive rocking.
Stringer/Block Integrity
Stringers may have minor notch damage (chipping at fork-entry points) that does not reduce load capacity much. Hairline cracks may be present if they do not extend through the full cross-section. Companion stringer repairs are common.
Grade C — Economy: Commonly Described Condition
Nail Condition
Protruding nails should be hammered flush before the pallet is used, since safety is the baseline at every grade. Nail type and condition are less closely evaluated beyond making sure none protrude.
Board Gaps
Board spacing may be irregular. This is generally acceptable for general storage. For loads with small items, specify maximum gap requirements when you request a quote.
Stains & Contamination
Water stains, ground contact discoloration, and weathering marks are all generally acceptable. Minor dirt and dust buildup is common. Active mold, oil contamination, chemical residue, and food contamination are problems at any grade.
Repairs
Multiple board replacements are common. Replacement boards may differ in width, thickness, and color from the originals. Companion stringers are common on any stringer with a full cross-section crack, and multiple companion stringers may be present.
Board Condition
End-splits, larger knot holes, surface checking, weathering, and cosmetic wear are all generally acceptable, as long as the boards still support the load without excessive flex.
Dimensional Accuracy
Overall length and width may be further from nominal. Moderate warping may be acceptable if the pallet can still be stacked and handled safely and sits on a flat surface without tipping.
Stringer/Block Integrity
Stringers may have notch damage, compression marks, and repaired cracks. All repairs should be structurally functional, and the pallet should still carry its intended load without noticeable deflection.
What Affects Pallet Pricing Beyond Grade
Grade is one starting point for pricing, but several other factors influence the final cost per pallet. Understanding these variables helps you plan and find ways to save without sacrificing quality. Pricing is by quote from partner suppliers.
Lumber Market Conditions
Varies with the lumber market
Pallet lumber prices are tied to the broader lumber commodities market, which is driven largely by housing construction demand. When housing activity surges, lumber prices rise and pallet costs tend to follow. Slowdowns in construction tend to lower lumber costs. New pallet pricing in particular follows current mill quotes.
Seasonality
Varies by time of year
Pallet demand often rises ahead of the holiday shipping season as companies stock up. During busy periods, both new and recycled pallets can be in high demand and prices may reflect tighter supply. Slower periods earlier in the year can offer better availability. Ordering ahead of peak season may help.
Order Quantity
Often lower per pallet on larger orders
Larger orders can reduce per-unit handling, sorting, and delivery costs, and suppliers may reflect that in pricing. Ongoing recurring orders may also be priced differently from one-off purchases. Ask a partner supplier what quantity changes the price.
Pallet Size
Tracks material cost
Larger pallets use more lumber, so a 48x48 pallet generally costs more than a 48x40, and smaller pallets like the 36x36 use less material. Non-standard sizes may cost more because there are fewer of them in the recycled supply and they may need custom cutting.
Wood Species
Hardwood generally costs more
Softwood pallets (pine, spruce, fir) are the usual baseline. Hardwood pallets (oak, maple, hickory) generally cost more because of higher raw material costs, harder-to-work lumber (more saw blade wear, more nail splitting), and heavier weight increasing handling costs. Mixed hardwood pallets sit somewhere in between where available.
Heat Treatment (ISPM 15)
Adds a treatment step
Heat treatment adds a cost per pallet. The cost covers kiln energy, labor for loading and unloading the kiln chamber, temperature monitoring and documentation, and the IPPC mark. Batch size can matter, because the kiln uses similar energy whether half-full or full. Treatment is performed by authorized treatment providers.
Mixing Grades Strategically
Many businesses default to a single pallet grade for all applications and may end up overpaying. Operations often use different grades for different purposes, matching quality to the actual requirement at each point in their supply chain. Here is how a mixed-grade approach works.
The Core Principle
Use Grade A pallets only where the customer or system demands it. Use Grade B for the majority of your operations. Use Grade C where appearance and tolerances do not matter. Many operations split their pallet needs across grades rather than buying a single grade for everything.
Because lower grades often cost less, matching each grade to the actual requirement can reduce spend without hurting operational performance. Ask for a quote on each grade to compare.
Where to Use Each Grade
Grade A (Outward-Facing / Premium)
- ▶Finished goods shipping to retail distribution centers
- ▶Automated warehouse and AS/RS system pallets
- ▶Export shipments where pallet appearance matters
- ▶Applications with strict cleanliness requirements
- ▶Customer-facing deliveries for premium brands
Grade B (Internal / General Operations)
- ▶Work-in-progress staging on the production floor
- ▶Internal warehouse transfers between buildings or zones
- ▶Domestic ground freight to non-retail customers
- ▶Raw material receiving and storage
- ▶Multi-trip pallets in closed-loop supply chains
Grade C (One-Way / Disposable)
- ▶One-way shipments where the pallet is not expected back
- ▶Export loads where the pallet stays at the destination country
- ▶Temporary outdoor storage of durable goods
- ▶Construction site deliveries
- ▶Internal scrap and waste pallet for non-shippable uses
How Used Pallets Are Commonly Repaired
A Grade C pallet is not necessarily a lost cause. Recyclers commonly repair heavily used pallets and sort them back into a higher grade where the repair allows. Here is how repair typically works and what determines whether a pallet can be upgraded.
Initial Assessment & Triage
Recyclers commonly evaluate each incoming pallet for repairability. The questions are usually: How many boards need replacement? Are the stringers structurally sound? Can the pallet reach the target grade after repair? If the repair would cost too much relative to the pallet's value, the pallet is typically dismantled for lumber recovery instead.
Board Removal
Damaged, cracked, or rotted boards are removed using a pneumatic pry bar or automated board puller, ideally without damaging the stringer notches. Nails are extracted or driven below the surface. Removed boards are typically sorted, with usable sections cut for spacers and shims and the rest ground into mulch.
Stringer Repair & Reinforcement
Cracked stringers commonly receive companion boards, pieces of lumber nailed alongside the damaged area to help restore structural capacity. For block pallets, loose blocks are re-fastened with new nails. Severely damaged stringers (crushed, rotted, or cracked through a large part of the cross-section) are usually replaced entirely, often with a jig to maintain dimensional accuracy.
Board Replacement
Replacement boards, sourced from dismantled pallets or cut from new lumber, are positioned in a nailing jig and fastened with helical or ring-shank nails. Replacement boards are generally selected to match the thickness and width of the original boards as closely as possible. Where appearance matters, wood species and color tone may be matched as well.
Nail Inspection & Flush Nailing
The whole pallet, not just the repair area, is typically checked for nail problems. Protruding nails are hammered flush, missing nails are replaced, and loose nails are driven deeper or replaced with longer fasteners. A single protruding nail is a common reason a pallet will not be called Grade A.
Dimensional Check & Re-Grading
The repaired pallet is measured to confirm it is close to its target dimensions and checked to make sure it sits flat without rocking. Lead boards are inspected for chamfer condition. The pallet is then sorted by grade. How much a repair can improve a pallet depends on the condition of the original stringers and the quality of the repair.
Grade Selection Scenarios
Choosing the right grade is easier when you see how businesses in similar situations tend to decide. Here are six illustrative scenarios, not specific customers, with the grade commonly chosen and the reasoning behind it.
Scenario 1: Food Manufacturer Shipping to Retail Distribution Centers
Situation: A food company ships lightweight, crushable products such as shrink-wrapped cases of chips and crackers to retail distribution centers. The receiving customer requires GMA 48x40 pallets with no visible damage, stains, or protruding nails.
Why: Large retail receiving departments often have strict pallet standards, and non-compliant pallets can be rejected at the dock or trigger chargebacks. Grade A pallets are commonly described as clean and uniform, which tends to match those expectations. Lightweight, crushable products also benefit from a clean, even deck surface that helps prevent packaging damage. Confirm your customer's pallet requirements before ordering.
Scenario 2: Steel Distributor Moving Coils Between Buildings
Situation: A steel service center moves very heavy steel coils between its cutting facility and its warehouse by truck. The same set of pallets cycles back and forth in a closed loop. Appearance is irrelevant; the pallets never leave the company's own facilities.
Why: This is a typical Grade C application: internal use, no external customer visibility, closed-loop logistics, and no outside requirements. Because the loads are extremely heavy, the pallets should be hardwood, such as oak or maple, to handle the weight. The cosmetic wear and repairs typical of Grade C have little impact on performance in this application. Confirm load ratings with the supplier.
Scenario 3: Electronics Distributor Shipping to Automated Warehouses
Situation: An electronics distributor ships consumer electronics such as TVs, laptops, and smartphones to fulfillment warehouses. Those warehouses specify pallet dimensions, no protruding nails, and pallets suitable for automated conveyor and robotic handling systems.
Why: Automated material handling systems have tight dimensional tolerances. A pallet that is warped, has uneven deck boards, or has protruding nails can jam conveyors, damage equipment, and halt operations, and non-compliant inbound shipments may be refused or charged fees. Grade A is commonly chosen for this kind of work, and it also helps protect high-value electronics from pallet-related damage during automated handling.
Scenario 4: Landscaping Supply Company with Seasonal Outdoor Storage
Situation: A landscaping supply company needs a large number of pallets to store bags of mulch, gravel, and soil outdoors in its yard during the spring selling season. The pallets will sit on dirt, be exposed to Arizona sun, and be driven over by skid-steer loaders during yard operations. Most pallets will be worn out by the end of the season.
Why: This is a typical Grade C application. The pallets will face harsh conditions, including UV, heat, dirt, and heavy equipment traffic, that wear down any grade within months. Paying more for Grade A or B tends not to pay off when the conditions reduce any pallet to Grade C quality quickly. Grade C is commonly chosen for seasonal, disposable-use pallets.
Scenario 5: Exporter Shipping Overseas
Situation: A manufacturer ships equipment overseas on pallets that must be treated to ISPM 15 and carry the IPPC mark. The receiving port and buyer may also care about how the pallets look on arrival.
Why: Heat treatment to ISPM 15 and the IPPC mark are generally required for wood packaging in international shipping, regardless of grade, so ask for treated pallets. Grade A is commonly chosen where appearance matters or the buyer is particular. Grade B is often enough when the pallets only need to be sound and compliant. Confirm the destination country's current requirements with your receiver.
Scenario 6: E-Commerce Startup on a Tight Budget
Situation: A fast-growing direct-to-consumer brand ships fitness equipment on pallets to regional LTL carriers for last-mile delivery. Pallets are one-way: the carrier delivers and the end customer disposes of the pallet. Budget is tight, and every dollar saved on packaging goes toward marketing.
Why: Grade B is often the sweet spot for this application. The pallets must be structurally sound to survive LTL handling, which is generally rougher than truckload because loads are handled several times per shipment, so Grade C's potential for board failures is a risk. However, Grade A's premium appearance and tight tolerances are usually unnecessary because the end customer does not evaluate pallet quality. As volume grows, a mix of Grade B and Grade C based on product weight may make sense.
