How to Add Weight-Based Extra Fees in WooCommerce for Heavy Orders

Shipping heavy items can quietly eat into your margins. This use case helps you set up a smart fee rule that automatically adds a charge when an order’s weight crosses a limit.

Overview

You can charge extra fees for orders over a set weight (like 10kg). This helps you recover shipping costs and maintain profitability. (Plugin feature: Weight-Based Fees)

Business Impact Example: If you're losing $8 per order on oversized items, adding a surcharge ensures you cover that cost, without manual adjustments or cutting into your profit.

Preconditions

• Extra Fees plugin is installed and activated.
• Product weights must be defined in WooCommerce

Steps (Basic Flow)

1. Go to WooCommerce > Extra Fees
2. Click Add New Fee
3. Set the Fee Name: Heavy Order Fees
4. Choose Fee Type per kg
5. Set the Amount: $15

6. Under Conditions, add a Weight rule — greater than 10kg

   

7. Click Save Fees

8. At checkout, customers with carts over 10kg will see the extra fee added automatically

   

Alternate Flow

• If the order is below the weight threshold, no fee is applied.

Expected Outcome

• You protect your margins on heavy shipments
• Customers see a fair, automated surcharge instead of unclear shipping fees
