With the “Printify Shipping Calculator” you don't need to do anything. New shipping rates will be integrated automatically so the changes will be reflected.

In order to edit custom shipping rates in Shopify, please visit your “Shopify Shipping Settings” and choose the shipping zone you would like to edit from the “Shipping rates at checkout” list. Afterwards, please edit “Weight/Price based” rates, depending which you already set up.
