When your Shopify store uses market-driven shipping, Shopify no longer has shipping profiles. Shipping rates live in your Shopify Markets instead, and a rate covers either all products or the products in one collection. So Shuttle connects each Etsy shipping profile to a Shopify collection. Products then pick up the right rates in Shopify and the right shipping profile on Etsy when they transfer.
Where to find the Shipping → Collections page
The Shipping → Collections page is where you map Etsy shipping profiles to Shopify collections. To open it, go to Settings > Catalog Mapping > Shipping → Collections.
The Shipping → Collections page only appears in the menu once your Shopify store has moved to market-driven shipping. Until then, Shuttle keeps using the Shipping Profiles page.
Set your default shipping
The Default shipping card holds two fallbacks. Shuttle uses them when no row in the mapping table matches the product being transferred.
Etsy default: the Etsy shipping profile for products transferred to Etsy that are not in any mapped collection. Etsy sometimes hides calculated profiles, so they may not all appear in this list. If you have not picked one, Shuttle uses the first Etsy shipping profile it has for your shop.
Shopify default collection: the collection that products transferred to Shopify join when their Etsy shipping profile has no collection mapped. Click Select collection to choose one. To change or remove it later, open the menu next to the collection and choose Change collection or Clear.
If you leave the Shopify default collection empty, those products join no collection. They then get the Shopify Markets rates you set for all products.
Map each Etsy shipping profile to a collection
The Map Etsy shipping profiles to Shopify collections card shows one numbered row for each of your Etsy shipping profiles. Mapping is optional, so you only need to fill in the rows you want.
Go to Settings > Catalog Mapping > Shipping → Collections.
In the row for an Etsy shipping profile, click Select collection and search for the Shopify collection to use.
Repeat for any other profiles you want to map.
Click Save.
To change a mapped row, open the menu next to its collection and choose Change collection, or choose Clear to remove the mapping. If you have added a shipping profile on Etsy or a collection on Shopify since you opened the page, click Refresh to load it.
If the card says you have no Etsy shipping profiles, create one in your Etsy shop and then click Refresh.
Create a shipping collection for a profile
Create collection makes a new Shopify collection for an Etsy shipping profile and maps it in one step. That way you don't have to set the collection up in Shopify first.
The new collection is named after the Etsy profile with "Shipping: " in front, for example "Shipping: Hooks". The prefix keeps your shipping collections together in Shopify and separate from your storefront collections. The collection is not published to your online store, and Shuttle saves the row straight away.
A new collection does not change anything at checkout on its own. After you create it, attach a shipping rate to it in your Shopify Markets settings. The row shows a Shopify Markets link that takes you there.
How Shuttle uses the mapping for products transferred to Shopify
When a product transfers from Etsy to Shopify, Shuttle adds it to the collection mapped to its Etsy shipping profile. If that profile has no row, the product joins your Shopify default collection instead, or no collection if you have not set one. Shuttle adds the product to the shipping collection but does not take it out of any other collection.
This only happens when Auto-assign shipping profiles is turned on. You'll find it in the Shipping profile section of Settings > Products > Etsy → Shopify.
How Shuttle picks the Etsy shipping profile for products transferred to Etsy
When a product transfers from Shopify to Etsy, Shuttle checks the rows of the mapping table in their numbered order. The first row whose collection contains the product decides its Etsy shipping profile. This matters when a product is in more than one mapped collection, because only the first matching row counts.
If a matching row points to an Etsy shipping profile that no longer exists in your Etsy shop, Shuttle skips that row and moves on to the next one. If no row matches, the product gets your Etsy default profile.
What happens to the Shipping Profiles page after the move
Once your Shopify store moves to market-driven shipping, the Shipping Profiles page becomes read-only and Shuttle no longer uses it. A banner at the top links to the Shipping → Collections page.
The Shipping Profiles page keeps your previous Etsy-to-Shopify profile pairs for reference. That makes it easy to pick the matching collection for each Etsy profile on the Shipping → Collections page. You can't edit or save anything on the Shipping Profiles page while it is read-only.
