Hi there!
I understand you’d like the shipping method to automatically switch to a higher class when the total weight of items in the cart exceeds the allowed limit for the cheaper shipping class.
By default, WooCommerce doesn’t include a feature that automatically moves an order to a different shipping class based on the combined weight of products. The built-in shipping classes only help you assign different rates to products but don’t dynamically reassign them during checkout.
To achieve this behavior, you’d need to either:
- Use a weight-based shipping plugin that can automatically apply the correct rate depending on the total cart weight, or
- Implement a custom code snippet to dynamically adjust the shipping class or method at checkout.
Since custom coding falls outside our support scope, I recommend checking plugin like:
These plugins allow you to define shipping rules based on total cart weight and automatically apply the appropriate shipping method.
I hope this helps.
It’s been a while since we heard back from you for this reason we are closing this thread.
