Did i buy the Wrong Plywood?

I am starting the construction of modular kitchen, two wardrobes and a TV cabinet soon.

I talked to my Carpenter for the list of items to be bought.

He said to buy BWP ply 12mm and bwp blockboard 19mm. Upon asking him about Brands he said Gattani is good, century and greenply cost more as they have "brand" cost included, so we decided to buy Gattani (he didn't suggest us any shop, neither he accompanied us to the shop)

I went to a largest shop in town where the salesman took me to their warehouse for choosing and inspection of material to be bought.

He said they had two grades of ply and blackboards; namely BWP and Commercial (MR)

So as decided earlier we got the delivery of Gattani BWP Ply and Blockboards. 19mm Blockboard costed 110/sq feet and 12mm ply 78/sq feet. (Shop quoted Century 19mm for 140/sq feet)

Now upon inspection at my home is see that:

The 19mm Blockboard has printed on it

IS:1659 Type:COM Grade:BWP and also (E1 grade resin, termite resistant, borer proof, glp inside etc)

The 12mm Plywood says

IS:303 Type:AA Grade:BWP (etc same as 19mm)

Now my question is I saw somewhere and also Gpt said that "True BWP" is actually IS:710....I also remember youtube video recommending Sainik710.

So did i not purchase the correct ply for kitchen areas?

Is Gattani selling selling lower quality material but tagging them as BWP?
