What a shortage looks like at the dock
A planner sees it first on the schedule. Containers are late back from a plant, the pool is below the count the line needs, or a launch calls for more than the fleet holds. The line cannot stop, so something has to carry parts for a few weeks. That something must not change the pack: the same footprint, the same count, a loaded weight the dock equipment can lift.
Write the request the way a planner writes the fix. Footprint first. Inside height second. Standard pack quantity third. Loaded weight fourth. Then how many, and by when. A few hundred boxes at a time is typical.
Matching the returnable
- Footprint. If the returnable is 48 x 45 in, the backup is 48 x 45 in. Overhang costs strength: Virginia Tech work found effective box compression strength decreases as pallet overhang increases, so match the pallet to the box.
- Inside height. Pick the height that holds the pack with room at the top. The height tells you the wall count by the ranges makers cite: 30 to 36 in for 2-wall, 34 to 40 in for 3-wall, 36 to 41 in for 4-wall, 36 to 46 in for 5-wall.
- Wall count and bottom. Dense parts want 4- or 5-wall and a full flap bottom. A lighter pack can use triple wall. A partial flap bottom needs a slip sheet.
- Grade. Ask for Grade A, single trip, clean and dry. A backup pack that fails on the dock is worse than none. See the grade sheet.
Check the weight before you check the price
Compare the loaded weight to the range sellers cite for the wall count. A 1,150 lb pack is inside the 1,000 to 1,600 lb cited for triple wall, and near enough to the middle that the stamp matters. A 2,400 lb pack is above anything cited for triple wall, and it points to 5-wall. The spec finder does this check for you and flags weights above the range.
After the shortage
A backup pack is a stand-in. When the returnables come back, the gaylords are single-trip empties at the receiving plant, and the plant can list them. See clearing empties after a launch or program and recycling for boxes past reuse.
Facts and figures
- Automotive packaging for ocean containers is generally one-way (expendable) because returning it costs too much (Automotive Logistics, January 13, 2017). (automotivelogistics.media, retrieved 2026-11-11.)
- The longer the logistics leg, the less practical returnable packaging becomes, and spare parts shipped to service centers usually go one-way in expendable packaging. (macfarlanepackaging.com, retrieved 2026-11-11.)
- Packaging Corporation of America offers expendable triple-wall corrugated for overseas automotive shipments in place of returnable plastic containers or metal racks. (packagingcorp.com, retrieved 2026-11-11.)
Terms
- returnable container: A plastic, metal or wood container that cycles between a supplier and a plant; gaylords stand in for them when the returnables run short.
- backup pack: The expendable pack a supplier ships when its returnable containers are short; it should match the returnable's footprint and pack quantity.
- expendable packaging: One-way packaging, usually corrugated, that is not returned to the shipper; in automotive it covers long lanes, export and shortages of returnables.
