One material with multiple brands

Dear All,

We are in Gas industry, following is the scenario:

We purchase one material, same specifications but with multiple origins (brands), example:

1. High Pressure Gas Regulator 1/2 inch 40 bar (Brand is Rego)

2. High Pressure Gas Regulator 1/2 inch 40 bar (Brand is Cavania)

3. High Pressure Gas Regulator 1/2 inch 40 bar (Brand is Cotrako)

As we need to differentiate the quantity in warehouse & the price for each brand, our plan was to create a separate material code for each brand.

Is there another work around instead of creating multiple material codes ?

Appreciate your feedback.

Thanks in advance
