The steps to publish products on AliExpress are as follows:

First, log in to your AliExpress account and enter the Seller Center page.

On the Seller Center page, click "Product Management" and then select "Publish New Products".

On the New Product Publish page, fill in the product information. Including product title, description, price, inventory, shipping, shipping address and other information. You can add multiple SKUs (product variations) as needed, as well as set product attributes and categories.

Add product pictures. You can upload multiple pictures and sort and adjust them as needed.

Preview and edit product information. You can view product information and pictures on the preview page and edit and modify them.

Submit product review. Before publishing a product, you need to submit the product for review. The review usually takes a few days, and the product will be available for sale on AliExpress after the review is passed.

Receive orders and ship. Once the product is available for sale online, buyers can place orders to purchase it. The seller needs to process the order in a timely manner and ship and track it according to the selected logistics method.

Confirm the receipt and process refunds. After the seller receives the payment from the buyer, he needs to confirm the receipt and process refunds and complaints if necessary.
