Your rules

Conditions and shipping classes

Match rules by weight, number of items or subtotal, and by shipping class.

The When, From, To and Shipping class columns decide whether a rule matches an order.

Conditions

When	Measures	Example
Always	Nothing: the rule matches every order (that fits its shipping class)	A catch-all last rule
Weight	The order's weight, in your store's unit: each product's weight × its quantity, added up	0–5 lbs, 5–20 lbs, over 20 lbs
Number of items	The quantities in the cart, added up	1–3 items, 4 or more
Subtotal	The line totals after coupons, including tax when your store shows prices with tax	Over $150

From and To are both included, and either can be empty:

From empty, To 5: 5 or less
From 5, To 20: 5 up to and including 20
From 20, To empty: 20 or more

Decimals can use a comma or a point. Only items that need shipping count: virtual products are left out.

Note

Bands that share an end, like 0–5 and 5–20, are fine: an order of exactly 5 matches the first, because it's higher in the table.

Shipping classes

Shipping classes are WooCommerce's way to group products that ship alike: "Bulky", "Fragile", "Small parcel". Create them under WooCommerce → Settings → Shipping → Classes and set one on each product's Shipping tab.

A rule's Shipping class column can be:

Any: the class doesn't matter.
No shipping class: the order has at least one item without a class.
A class: the order has at least one item of that class.

The rule's cost is for the whole order. So a rule for "Bulky" at the top of the table prices every order with a bulky item, bulky or not:

When	Shipping class	Cost	Label
Always	Bulky	49	Freight delivery
Weight up to 5	Any	6.95
Weight 5–20	Any	9.95 + 0.50 per lb

An order with a sofa and a mug ships by freight for $49; an order with only mugs ships by weight.

Tip

Pricing each class on its own and adding the costs up ("$49 for the sofa, plus $6.95 for the mugs") is what Per shipping class in Rateline Pro does.
