US-MX connects the TikTok Shop US and TikTok Shop Mexico stores associated with the same Shopify store. After the stores are connected, you can copy products from the US store to the Mexico store, set local MXN prices and editable product information, and view order processing information for the Mexico store.
Overview
US-MX connection is designed for merchants with the following store relationship:
Shopify -> TikTok Shop US -> TikTok Shop Mexico
The system verifies the relationship between all three stores before enabling product operations. Product copying, editing, mapping, activation, and deactivation are available only when the store relationship is connected and active.
Prices and certain product information in the Mexico store can be maintained separately. Changes made in the Mexico store do not modify the corresponding US store products.
Prerequisites
Before you start, make sure that:
Your Shopify store is connected.
The TikTok Shop US and TikTok Shop Mexico stores associated with the Shopify store are authorized.
The US and Mexico stores belong to the same store relationship supported by US-MX 4PL.
Your account has store and product management permissions.
To connect the TikTok Shop Mexico store, you must connect all three stores: Shopify, TikTok Shop US, and TikTok Shop Mexico.
Connect the TikTok Shop Mexico store
Before connecting the Mexico store, sign in to the TikTok Shop account for the Mexico market.
When Shopify and TikTok Shop US are already connected
In the connected US store, click "+ " to open the store connection settings
On the Set Up page, click Connect for TikTok Shop, select the Mexico market, and continue through the TikTok Shop authorization process.
After authorization succeeds, the page confirms that Shopify, TikTok Shop US, and TikTok Shop Mexico are connected. Click Get started to open the home page.
Complete the initial setup
When you first open a connected Mexico store, the home page displays a three-step setup guide. Complete the guide before managing US-MX 4PL products.
1. Set the product pricing rule
In Customize your products price, enter the USD/MXN exchange rate, then click Apply to all products.
The exchange rate must be greater than 0.
The system uses
US store price x exchange rateto calculate the default MXN price for Mexico store products.This rule does not modify US store products and does not immediately create or update Mexico store products.
When copying products, you can still edit the final MXN price for individual SKUs. Manual changes apply only to the current copy operation.
2. Import products from the US store
Click Import products to open the Products on US TikTok Shop tab. Select the products that you want to copy to the Mexico store, then click Copy.
3. Review sync settings
Click Settings to review the existing sync settings.
Manage US-MX products
The Products page contains the following three tabs:
Tab | Purpose | Available actions |
Products synced to MX TikTok Shop | View products with an existing Shopify and TikTok Shop Mexico sync relationship | Edit, activate, deactivate, unmap, and bulk activate, deactivate, or delete products |
Products on US TikTok Shop | View all products in the US store | Copy products individually or in bulk |
Unmapped products | View Mexico store products that are not yet mapped | Map products to Shopify products |
Copy US store products to the Mexico store
Open Products on US TikTok Shop.
Click Copy next to the product you want to copy. To process multiple products, select them and click Copy in the bulk action bar.
In the dialog, enter or confirm the exchange rate. The system automatically calculates the MXN price for each SKU.
If needed, edit the MXN price for any SKU.
Click the Save button to start copying.
After you submit the copy request, the page displays a notification at the top and updates the product status:
Processing: The request was submitted and is being processed. This does not mean that the product has been published successfully.
Active / current TikTok Shop status: The product was copied successfully. The status returned by TikTok Shop is the source of truth.
Draft: The product was copied as a draft. Check the Mexico store's product publishing requirements, then complete the product through Edit.
Copy failed reason: The copy operation failed. Fix the issue shown in the product row, then try again.
Each US store product can create only one corresponding Mexico store product. After copying, switch to Products synced to MX TikTok Shop when the product already has a Shopify relationship, or Unmapped products when it does not. Refresh the list to wait for the status to update.
Edit Mexico store products
Open Products synced to MX TikTok Shop.
Click Edit next to the product.
Update the editable Mexico store product information, then save your changes.
To preserve the relationship between the US and Mexico stores, you cannot edit the following fields for Mexico store products:
Product category
Sales attributes
Inventory
SKU
Editable fields saved in the Mexico store are retained as local custom information. Future syncs from the US store or Shopify do not overwrite these protected fields.
Activate, deactivate, or delete Mexico store products
In Products synced to MX TikTok Shop, you can click Activate or Deactivate for an individual product, or select multiple products and use a bulk action.
Activating or deactivating a product affects only the Mexico store product. It does not change the status of the US store product.
Confirm carefully before deleting a product. Deletion removes the selected product and its sales data from TikTok Shop Mexico, but does not delete the corresponding US store product.
Map or unmap products
In Products synced to MX TikTok Shop, select Unmap to remove the mapping between a Mexico product and its Shopify product. After it is unmapped, the product moves to Unmapped products.
In Unmapped products, click Map to map a Mexico store product to a Shopify product. After mapping succeeds, the product moves to the MX management list and the associated US store mapping relationship is retained.
Unmapping affects future product syncs. Confirm that the action is required before proceeding.
View order status
On the Mexico store's Orders page, you can view order processing information.
FAQs
Why is the Copy button disabled for a US store product?
Each US store product can be copied only once to create the corresponding Mexico store product. Check whether the product's Copy status is already Copied.
Why does a product show Processing after copying?
Processing means that the system accepted the copy request and the product is still being created or receiving a status update. Refresh the list later to view the final result. If a failure reason appears, resolve the issue and copy the product again.
Why does a product show Draft after copying?
Draft usually means that the product does not yet meet the Mexico store's publishing requirements. Open Edit, add or correct the editable product information, and continue processing the product.
Will changing the MXN price affect the US store price?
No. The MXN price applies only to the current Mexico store product. An SKU price changed manually in the copy dialog does not change the default exchange rate or the US store price.
