Shipping weight [shipping_weight]

The shipping weight [shipping_weight] attribute lets you include the weight to use when calculating shipping costs through your Merchant Center settings. For example, you would submit the shipping weight attribute when using carrier-calculated rates.

When to use

Optional for each product

If you set your account shipping settings in Merchant Center based on weight, then use the shipping weight [shipping_weight] attribute to submit the weight for each product. Methods that calculate shipping using weight include carrier-calculated rates and shipping weight tables. If the weight for your product exceeds the supported value, use the shipping label [shipping_label] attribute instead to configure shipping rates. Learn more about shipping settings

Freight shipping, less than truckload shipping (LTL)
  • Use a shipping table to set up LTL shipping costs in your account shipping settings. Carrier-calculated rates don’t support LTL pricing for heavy or large products.
  • Submit the shipping label [shipping_label] attribute to assign a freight class to each product and define multiple shipping groups in Merchant Center. You can then create tables specific to each freight class.
  • Use the highest possible shipping cost a user might pay. If you have difficulties submitting accurate shipping costs (for example, due to real-time cost calculations at checkout), you should submit the highest possible shipping cost a user might pay.
