Amazon’s Editorial Team has always struck me as rather ineffective in the performance of its duties, to be sure, but methinks its denizens have deployed LLM for the recent re-writing of the SHC (“Seller Help Content”) page Shipping and routing requirements (link, Seller Central) , resulting yet again in conflicting information in that page’s ‘Box dimensions’ & ‘Box weight’ ¶'s:
Box dimensions
Boxes containing multiple standard-size items or oversized items must not exceed 25.00 inches on any side. A box may only exceed the 25.00 inch limit if it contains oversize units that measure longer than 25.00 inches. Boxes that are excessively large relative to the oversize units (exceeding the 2 inches of cushioning recommended above) may be subject to restriction of shipping privileges, additional fees, or refusal at a fulfillment center.
Boxes that contain a single oversize item that do not fit the above dimension limitations must comply with the following requirements:
Boxes may exceed 63.5 cm, but must not measure more than 73.7 cm.
Boxes may exceed 23 kg, but must not weigh more than 30 kg.exceed 63.5 cm on any side. A box may exceed the 63.5 cm if it contains oversize units that measure longer than 63.5 cm. Boxes that are excessively large relative to the oversize units may be subject to restriction of shipping privileges, additional fees, or refusal at a fulfillment center.
Shipping single oversized items that weigh weight more than 30 kg is allowed only by enrolling into the FBA Heavy and Bulky program. In this case, the product box must not exceed 150 cm in length or a girth of more than 3 meters [girth = (2 x width) + (2 x height) + length].
Note: Any box that weighs more than 15 kg must contain “Team Lift”/“Heavy Package” safety label displayed on top and sides of each heavy-weight box (5 labels in total).
Important: Box dimension policies are strictly enforced. Sending oversize boxes to the fulfillment center may lead to blocking of future shipments.
Box weight
Weigh and measure boxes and pallets accurately and ensure that the correct values are provided for every shipment. All cartons must also meet these weight requirements:
Boxes must not exceed the standard weight limit of 50.00 lb, unless they contain one single item that exceeds 50.00 lb.
For a single item that exceeds 50.00 lb, attach a label that clearly indicates Team Lift on the top and sides of the box.
For a single item that exceeds 100.00 lb, attach a label that clearly indicates Mechanical Lift on the top and sides of the box.
Boxes containing jewelry or watches must not exceed 40.00 lb.
UPS allowances for larger box dimensions and weight do not apply to boxes containing multiple standard-size items.
Important: Box weight policies are strictly enforced. Sending overweight cartons to the fulfillment center may lead to blocking of future shipments.
Note:
Accurate box weight and dimensions are required for all shipments, even if you opt to not provide box content information in Seller Central, or if you are not using an Amazon partnered carrier.
We do not provide Seller the “Team lift” or “Mechanical lift” labels for now, you may generate it by yourself, and please make sure to use local language of the shipment ship-to country.
I’ve been monitoring that page since 31May2017, and have only seen relatively- minimal changes (the removal of the formerly available “How To Pack” video back in November of 2019, the addition of the Huawei Listed Entity disclaimer, etc.) in all that time.
