1、Packaging Appearance Requirements: Before shipping and entering the warehouse, it is necessary to inspect the appearance of each box of goods, as Amazon has strict requirements for the appearance of FBA goods. If the outer box is damaged or the label font is blurry, Amazon may reject the goods.

2、Country Labels: Generally, Amazon requires sellers to affix two country labels on the upper right corner of the narrow side of each box of goods, with a size of a 4cm square.

3、FBA Label: The FBA label is used to identify the outer packaging of goods when received by Amazon warehouses. It consists of FBA information and Code 128 barcode.

4、Made in China Label: For exports to the United States, South America, and Europe, it is necessary to have a "Made in China" label on the outer box and each product. Otherwise, it may be detained and returned by local customs.

5、Product SKU Code: The SKU code of a product is a unique identifier for a product with a specific category, model, and size.

6、Overweight Label and Battery Label: Firstly, it depends on the specific Amazon site. The handling methods for the US site and the UK site are different. For the US site, if a single item exceeds the weight limit, it needs to be labeled. In a package containing multiple items, the total weight should not exceed 50 pounds. If a single item exceeds 50 pounds, it needs to be shipped separately and clearly marked. For the UK site, the weight of a single carton should not exceed 15kg. If it exceeds 15kg, a "Heavy Package" label should be printed and affixed to the outer box.
