Multiple merchants are struggling with Shopify’s combined shipping rates when using multiple shipping profiles. The core issue: when customers order items from different profiles (e.g., value-based vs. weight-based, or different warehouse locations), Shopify automatically adds the shipping costs together rather than selecting the highest rate or charging a single consolidated fee.
Key Problems:
Heavy items mixed with light items result in double shipping charges
Merchants want to charge one shipping fee based on the largest/heaviest item or total order weight
Official Response:
Shopify support and community moderators confirm this is a platform limitation with no native solution. The only workarounds suggested are:
Using third-party apps (though original poster resists due to high app fees)
Consolidating everything into a single shipping profile (loses granular control)
Status: Unresolved. Multiple users continue seeking solutions, with some considering migration from other platforms (like Wix) where this isn’t an issue.

I have multiple shipping profiles under one warehouse.
I ship most of my orders based on order value, but some items are really heavy and I have created shipping profiles for those to be based off of weight and carrier rates. When an order contains items from different shipping profiles the shipping rates are combined, but I need it to just choose the highest shipping rate and not combine them.
How do I disable the shipping profiles being added? I am not interested in having to download another app to make something work. I am paying so much in app fees because Shopify does not have solutions for simple things.
When using multiple shipping profiles, if orders contain products from different profiles or locations, this will result in combined rates at the checkout. Unfortunately, the only available workaround would be to use an app to set up more specific shipping rules.
I need to ship from two locations without combining shipping. I want to use flat rate shipping fees and allow customers to add to their cart from both locations
Really struggling with this limitation on shopify!
Is there a fix for this yet. I dont have this problem on Wix but want to move to shopify. Some items are small and shipping only cost small amount, but if a customer buys a really big item then shipping is a lot more. Surely I can include the small items with the big item and only charge the one shipping profile fee of the larger item. At the moment if they buy a small and larger item they get charged two lots of shipping, crazy.. Any fix?
