Restrictions within a shipping rate allow you to describe what conditions must be met for the shipping rate to show at checkout.
Keep in mind:
This restriction has everything to do with the total cost of the order.† Here you can define the minimum amount, maximum amount, or both to create a price range an order must meet in order for this rate to show at checkout.
† cost before any discounts, coupons, or taxes
Similar to value restrictions, weight restrictions allow you to control how much the order must weigh in order for the shipping rate to be shown at checkout.
Some shipping rates should only apply to a specific set of products. That is what product restrictions are for. Here you define what products (by SKU, type, tag, collection, or vendor) must - or must not - be present in the order for this shipping rate to show. These conditions come in two varieties: Product is and product is not.
Product is: All items in the order must match this list. If any products are ordered that are not on the list, this rate will not show
Product is not: Any combination of products may be ordered, but if even one of them match your product is not restriction, this rate will not show
Important note: If you are interested in creating a rate that shows as long as one of a specific product is in the order, please see our Price product restriction
