Shipment rules based on weight and price. Override rule?

Topic summary

A merchant is struggling with Shopify’s checkout system when offering free shipping thresholds based on order value. The core issue: price-based free shipping rules don’t account for product weight.

The Problem:

  • Free shipping triggers above a certain order amount
  • Heavy items (like sofas/furniture) qualify for free shipping based on price, but are too expensive to ship for free
  • Light, high-value items (jewelry) can reach the threshold easily and ship economically

Desired Solution:
The merchant wants a weight-based override that prevents free shipping from applying when items exceed a certain weight, even if the order value qualifies.

Status: The question remains unanswered—seeking guidance on whether Shopify’s native shipping rules support weight-based exceptions to price thresholds, or if alternative solutions (apps, custom logic) are needed.

I am experiencing an annoying situation with Shopify checkout system.

website: www.cphagen.com

In countries where I offer free shipping about a certain amount, I would love the system to take in consideration the weight of the purchased good.

Ex: the sofa in the screenshot below is above the “free shipping rate” based on the price BUT it’s way too heavy to actually be delivered for free!

Is there a way I could say to the system: weight override price limit?

Problem is that someone could purchase plenty of, exemple, nice jewels and reaching very high amounts.
But that is light and easy to ship.

Same can’t be said for big and heavy furniture.

I hope I have been clear.

Thank you very much for your help!
