Questions from the dock

Grade A has had no repairs and needs none. Grade B has been repaired with replaced deck boards, plates or plugs. The grade guide has the full ladder down to cores.

A pallet remanufactured from a mix of recycled and new lumber. It is stronger and more consistent than a used pallet and cheaper than an all-new build. See combo pallets.

In North America the standard is 48 x 40 inches, about 1,219 x 1,016 mm, often called the GMA pallet. The size table covers the others.

A stringer pallet rests on three or more parallel timbers. A block pallet rests on blocks with boards running both ways, so forks enter from any side. See the types hub.

If the destination applies ISPM 15 to wood packaging, yes. Heat treatment means the core of the wood reached at least 56 °C for at least 30 minutes. The ISPM 15 guide goes through it.

Look for the ISPM 15 mark burned or stamped on the side. The identification guide shows what is on it.

Keep them dry, off the ground and with air moving around the stack. Wood below 20 percent moisture will not support decay fungi. Read the mould guide.

Pallet recyclers and pallet companies buy sorted stacks and cores. This desk takes requests to buy and to sell; the sell page explains what usually counts.

The line is 20 percent moisture content. Pallets in a Forest Service survey were between 10 and 12 percent when used and 17 to 20 percent when new.

There is no single rule. A survey of recycler grades averaged 0.15 stringer repairs for A, 1.04 for B and 1.69 for C. The grade sheet draws the line at four repairs.
