Product conditions ask whether the items in the cart meet a test. They’re how you withdraw a shipping method for goods that can’t travel that way — fragile items, hazardous goods, oversized furniture.
Unlike shipping rates, customizations do not require product syncing. Shopify sends product data to customizations at checkout directly.

​
Available attributes

Attributes from different sets cannot be combined in one rule. SKU (set 2) and Product Metafield (set 3) will never appear in the same dropdown. See Parameter Sets.

​
Product Collection

Collections are matched by ID, not by name. Enter comma-separated IDs. See Finding Collection IDs for how to look one up.
Collections are often the most maintainable way to drive shipping rules. Merchandisers already curate them, and a product joining the collection automatically picks up the shipping behaviour — no tag to remember.

​
How the cart is evaluated

For each product condition you also choose how much of the cart must satisfy it:
This choice is what makes product conditions precise. “Hide express if any item is fragile” and “hide express if all items are fragile” are very different rules — pick deliberately.

​
Includes in list

The Includes in list and Not includes in list operators test membership against a list of values, rather than a single comparison. Use them when you have a set of SKUs or titles to match and don’t want a condition per value.

​
Number Of Product Metafield Values

Counts how many distinct values of a given product metafield appear across the cart.
Products with no value for the metafield are not counted.
This is the tool for mixed-cart problems — for example, hiding a consolidated shipping option when the cart draws from more than one warehouse or supplier.

​
Examples

No express delivery for fragile items
Freight only for a furniture collection
Subscriptions ship one way only
