Hello @Seller_PLIhTPjYySVyo

Thank you very much for reaching out in Amazon forums, this is Lucre, and I'll be glad to assist.

I understand you would like to know to list your products in Amazon.com just as you list in Amazon.ca. First, congratulations on having joined us, let me welcome you to the communities, feel free to post any question or experience in this forum and engage with other sellers and community managers 🥳

To your question, you can start posting by changing the marketplace on the left-hand corner, you will find a dropdown menu with the North America marketplaces (next to the Amazon Seller Central logo), and you can switch to go to the US marketplace.

Please review the below help pages related to your question:

If you have any other question regarding selling in the US, I recommend you to open your forum in the US forums for additional assistance via https://sellercentral.amazon.com/seller-forums.

Regards,

Lucre_Amazom
