# 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/flexport-amazon-us-shipping/), Flexport recommends that your supplier labels the cartons with the [FBA labels](https://www.flexport.com/help/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).
