# What Markings Should My Cartons Have?

Flexport recommends having your supplier mark cartons with the following information:

*Company Name: (**your company’s name**)*   Product SKU: (*your product SKU*)
*Country of Origin: (**e.g. China**)*   Gross Weight: (*weight of the carton, including packaging*)
*Net Weight: (**weight of the products without packaging**)*   Carton Dimensions: (*length X width X height*)

- Carton Series Count: (*X of X*)

If you are [shipping to an Amazon FBA warehouse](https://www.flexport.com/help/336-flexport-amazon-us-shipping), Flexport recommends that your supplier labels the cartons with the [FBA labels](https://www.flexport.com/help/79-amazon-fba-labeling-requirements). However, if your supplier is unable to label the cartons, the supplier **must** mark the cartons with the Amazon SKU (FNSKU).
