Product-specific quantity range based shipping charges
This feature is used to add the quantity range of specific products, category or variable products.
If we want to check that the special product's quantity range comes between two quantities then add a special shipping charge.
For eg, If the customer buys a Music category product and quantity between 1 to 10 then apply the flat $15 shipping charges.
Let's see the above example with a configured screenshot to get a better idea about it.

So in the above case, if in the cart Music products quantity is 6 and Clothes products are 5 then it will still consider the quantity range between 1 to 10 and will add the Flat $15 charge.
