Control which shipping methods are available based on the products in the cart.

Shipping Restriction Groups feature, you can create restriction groups (e.g., hazmat, chemical, oversized), assign them to products, and then set shipping methods to deny specific groups. During checkout, delivery options are automatically filtered so customers only see shipping methods that are valid for their cart contents. This reduces incorrect shipping selections, prevents order handling issues, and improves the overall checkout experience. The setup is flexible per tenant and scales well for large catalogs, since you manage rules through groups instead of maintaining long product-by-method exclusion lists.
