Double stacked pallets should be accessible by a forklift from the same side, and load bars, tension straps, air pillows, and/or diamond corrugated shims must be used to secure them during transit.

The shipping carton label should be placed on the exterior of each carton in an unobscured and easily visible location, preferably on the side of the carton. Do not place carton labels over a seam of the carton. Labels should be placed at least 1" away from corners, edges, or tape that may cover or distort the label. Labels are only placed on the top of a carton when the sides are too short (less than 7" H) to fit the label. Diagrams for recommended and not recommended label placement are provided, but specific pallet label placement guidelines are not mentioned.

The shipping carton label must be placed on the exterior of each carton in an unobscured and easily visible location, preferably on the side of the carton, and not over a seam. Labels should be at least 1" away from corners, edges, or tape. Avoid placing labels near corners to prevent damage in transit. If the carton sides are too short (less than 7" H), place labels on the top. Each carton should only have one GS1-128 label using an SSCC-18 barcode that must match the 856 (MAN02). The label must include the human-readable and barcoded PO number format, specify the product type in the PO on the REF02 segment, and include all mandatory fields. Proper labeling prevents delays in receipt or payment.
