Grade A pallets have had no repairs and need none; Grade B pallets have been repaired with replaced deck boards, plates or plugs. Both ship freight, but they are not interchangeable, and the difference is something you can read from the dock.
| Look at | Grade A | Grade B | Grade C |
|---|---|---|---|
| Stringers | Original, whole | Repaired or plugged | Several repairs |
| Deck boards | Original, intact | Some replaced | May not be fully intact |
| Plugs | None | Short boards nailed beside a cracked stringer, 6 to 24 inches long | Several |
| Appearance | Uniform | Mismatched wood and nails | Poor |
| Also called | Grade 1 | Grade 2 | Grade 3 |
No single sign defines the grade; the count and pattern of repairs does. The GMA organization no longer governs pallet specifications, so grade names are a trade convention, and a buyer's idea of Grade B may differ slightly from yours. Say what you see, not just the grade.
A clean outbound line, such as food or packaged consumer goods, wants Grade A. General freight, parts and industrial loads ship fine on Grade B. A pallet with several repairs and doubtful deck boards, Grade C, is usually a core. A clean-room line wants neither unless it is clean, dry and consistent; see medical devices.
Grade B is not a defect. It means a pallet that would otherwise have been ground was repaired and returned to use. That is also why it costs less than Grade A.
Grade A has no repairs. Grade B has been repaired with replaced deck boards, plates or plugs.
A pallet of poor appearance with usually several repairs, whose deck boards may not be fully intact.
A sound Grade B pallet ships freight, but the working load depends on the specific pallet.
