What is a pallet collar?
A pallet collar is a hinged wooden frame that sits on top of a standard pallet, converting the pallet from a flat deck into a shippable, stackable box. Collars have four or more pieces of 2-by-6 or 1-by-6 lumber connected at the corners with steel hinges that fold flat for return shipping and set up tool-free in seconds for use.
The collar system replaces single-use corrugated boxes for a wide range of industrial product shipping. Instead of boxing a load, pallet-wrapping it, and discarding the boxes at destination, the shipper uses a pallet, collars (one or more stacked for height), a lid, and strap. At the destination the collars fold flat, stack 20 to 40 high, and return to the shipper for the next cycle. The economics work for repeat domestic lane shipments and for industrial product moves where the shipper and receiver are in a long-term relationship.
Collars came to the US from Europe, where they have been standard for 30 years on EUR-pallet (800mm by 1200mm) and ISO-pallet shipping. The US market has adopted them for automotive parts, electronics, bulk-component moves, and anywhere the customer wants a reusable alternative to corrugated.
When collars make sense (and when they do not)
Collars make sense when: (1) the shipping lane is repeat-use between the same two sites, (2) the receiver can economically return the collars (typically within 500 miles or on a backhaul-matched truck lane), (3) the cargo is a mid-size industrial product (automotive parts, electronics assemblies, bulk components, hardware kits), (4) the shipper wants to eliminate corrugated waste and the receiver prefers a reusable intake, (5) the cargo stack-height varies and the shipper wants to use one collar for low loads and three stacked collars for tall loads.
Collars do not make sense when: (1) the lane is one-way and the receiver has no return path, (2) the cargo is high-value and needs a lockable solid-walled box (collar systems are not lockable), (3) the receiver cannot handle collar return economics, (4) the cargo volume is too low to justify the per-unit collar investment, (5) the cargo requires climate-controlled or weather-sealed packaging that a collar system does not provide.
For high-volume, repeat-lane shipping between committed partners, collars pay off within 10 to 30 cycles. Beyond that cycle count, collars are pure savings against corrugated.
Collar sizes and stacking
Standard 48 x 40 collar (GMA pallet)
The most common US collar fits a 48 inch by 40 inch GMA pallet. The collar is 48 by 40 inches outside, 46 by 38 inches inside, with 2-by-6 side walls and steel corner hinges. Height is 7.5 to 8 inches per collar; stackable 1 to 4 high per pallet.
Euro-pallet 1200 x 800 collar
The Euro-pallet collar is 1200mm by 800mm (47.2 inches by 31.5 inches), built to EUR-pallet dimensions for European and international lanes. Available in 1-by-6 and 2-by-6 side-wall grades.
Industrial 48 x 48 and 48 x 42 collars
For specialty pallet sizes (48 by 48 chemical pallets, 48 by 42 pharma, 36 by 36 drum pallets) we build to-dimension collars. Side-wall thickness, hinge count, and corner reinforcement are quoted per cycle count and product weight.
Half-pallet collars (24 x 40 and 24 x 20)
For small-footprint loads (demo bins, retail-ready displays, small-batch industrial) we supply half-pallet collars.
Collar lids and bases
A collar system typically has three components stacked on the pallet: the base (the pallet itself, often a GMA 48x40 or a Euro pallet), one or more collars (stacked to the required height), and the lid (a plywood top or a solid wood top).
The lid can be plain plywood, foam-faced plywood (for scratch-sensitive electronics), or solid wood with hinges that lift for easy access. For straps the system typically uses 2 to 4 polyester ratchet straps running top to bottom over the lid and under the pallet.
For stackable in-trailer loads the lid supports the next collar system above it, so lid thickness matters - typically 3/4-inch to 1-inch for stackable loads. For non-stackable single-tier loads a 1/2-inch lid is sufficient.
Collar programs and return economics
A collar program has three cost components: the one-time collar inventory purchase, the per-cycle wear-and-replace cost, and the return-leg freight. The collar inventory is sized for 1.5 to 2.5 times the number of outbound shipments in the longest float window (how long collars sit at the receiver before returning). The per-cycle wear is replacement of damaged collars and lids, typically 2 to 5 percent of the inventory per 100 cycles.
Return freight is the biggest variable. If the shipper has an outbound-and-backhaul truck relationship (the truck returns empty from the receiver to the shipper), collars return on the backhaul at near-zero marginal cost. If the collars must be returned on a separate LTL or truckload shipment, return freight can be 15 to 30 percent of the forward freight cost. Economics work in both cases if the lane is high-volume enough; we quote the breakeven.

Frequently asked questions
How many times can a pallet collar be reused?
Typical cycle life is 25 to 100 cycles depending on handling, cargo weight, and climate. Collars in high-abuse flows (heavy automotive parts, outdoor-exposed logistics) see the low end. Collars in protected indoor flows (electronics plants) see the high end. We quote a wear-and-replacement rate per 100 cycles so program economics are predictable.
Are pallet collars better than corrugated boxes?
For repeat-lane shipping between committed partners, collars pay off within 10 to 30 cycles against corrugated. The savings are the eliminated corrugated purchase, the eliminated box disposal, the smaller forward-and-return freight (collars fold flat for return at 10 to 15 percent of forward volume), and the reduction in packaging labor. Corrugated remains better for one-way shipping, low-volume lanes, and shipments to customers who cannot return the collars.
Can collars stack more than one high per pallet?
Yes. Standard collars stack 1 to 4 high per pallet (7.5 to 32 inches of total side-wall height). The stack is secured with a lid and 2 to 4 straps running top to bottom. The practical limit is cargo weight per layer, trailer height, and in-trailer stackability for the next layer above.
Do pallet collars require ISPM-15 for export?
Yes - any wood component crossing international borders requires ISPM-15 heat-treatment and IPPC stamping. We supply ISPM-15 stamped collars for export lanes. For Euro-pallet lanes between the US and EU this is standard spec.
What is the typical lead time on a new collar program?
For published-size collars from stock: 1 to 5 business days from PO. For custom-sized collars built to a specific pallet dimension: 10 to 15 business days from drawing approval. For a full program setup (collar inventory, lids, program documentation): 15 to 30 days from first quote to first delivery.
Do you supply lids separately from collars?
Yes. Lids are quoted separately - plain plywood, foam-faced plywood, or solid wood with lift-hinges. We also supply replacement lids for existing collar programs where the collars are in service but the lids need refresh.
How do collars compare to plastic pallet bins or returnable totes?
Collars give you a reusable, foldable-flat system at lower per-unit cost than plastic totes or bins. Plastic totes are better for cleanroom, climate-controlled, or chemical-resistant flows. Collars are better for industrial cargo at ambient conditions where fold-flat return economics matter. Many facilities run both systems in parallel for different cargo types.
Can I buy a mix of 1-by-6 and 2-by-6 side-wall collars for different cargo weights?
Yes - we quote a mixed inventory per cycle estimate. 1-by-6 is lighter and lower-cost, suited to cargo under 500 pounds per pallet. 2-by-6 is heavier and more durable, suited to cargo up to 2,000 pounds per pallet.
What hinges do you use on collars?
Steel butterfly hinges with powder-coat corrosion protection. Hinge count varies by collar size: 4 hinges on 48x40 collars (one at each corner), 6 to 8 hinges on larger or heavier-grade collars. Hinges are replaceable in the field with standard carpentry tools.
Can collar programs be shared across multiple shippers?
Yes - we quote pool collar programs where multiple shippers draw from a shared inventory and the pool operator handles collar movement, cleaning, and replacement. Pool economics work for 3PL networks, industry co-ops, and buyer-supplier consortia.
