The requirements are as follows:

Use a six-sided high-toughness packaging box with a complete lid, and the box will not collapse when pressure is applied to any side.

Each box must contain its own FBA Amazon logistics shipment label, and the label must be clear, moisture-proof and wear-resistant.

If a carton is to contain goods from multiple PO orders, then it must be ensured that a carton can only involve goods from a maximum of 5 PO orders.

The net weight of the carton packaging shall not exceed 22.5KG (50 pounds). If the net weight of a single item sold exceeds 22.5KG (50 pounds), a "Team Lift" label must be affixed to the carton, indicating that a team is required to operate; if the net weight of the box exceeds 45KG (100 pounds), a "Mech Lift" label must be affixed to the carton, indicating that a machine is required to operate.

The net weight of cartons containing jewelry and watches cannot exceed 18KG (40 pounds).

The dimensions of any side of the carton must not exceed 63.5CM, unless the size of the single-unit product is larger than 63.5CM. If the carton size exceeds the standard, the carton needs to be placed on a 1mX1.25m pallet to facilitate the Amazon FBA warehouse staff to use mechanical handling operations.

The carton and packaging materials (such as padding, fillers) must fully protect the goods during transportation. If the goods are packed with packaging materials that are not accepted by the Amazon fulfillment center, the goods will be rejected or additional packaging fees will be paid.

The size of the carton is selected to ensure that there is a minimum amount of free space in the carton after the goods are placed. Space utilization can also be maximized by packing multiple products in one carton (without damaging the goods).

Cartons cannot be wrapped with strapping tape, elastic bands, large staples or nylon fiber tape, as they pose a safety hazard to warehouse colleagues.

Point-of-sale containers commonly used to display goods (such as front-opening boxes or boxes without lids) must not be used.

In addition, Amazon also prohibits the entry of certain items, including alcoholic beverages (including/non-alcoholic beer), vehicle tires, sky lanterns or water lanterns, gift cards and other stored value instruments, products with unauthorized marketing materials (such as brochures, price tags or other non-Amazon stickers), damaged or defective goods, loosely packaged batteries, and other products that are not suitable for sale on Amazon.
