In Merriam-Webster dictionary, none of the meaning of 'slab' is 'range'. But slab is also used to mean range in India. For example, limit X1 for weight slab 10-20kg, limit X2 for slab 20-30 kg.

I've never heard slab used to convey range. Also, I would interpret "limit X1 for weight slab 10-20 kg* as meaning X1 is the limit for slabs weighing 10-20 kg." Do you have another example not involving weight?– Richard KayserCommented Jul 3, 2020 at 16:12

Freight charges X1 for transporting a box in a weight slab 100-200kg, X2 for transporting a box in a weight slab 200-300kg. Thank you– Amrit UpadhyayCommented Jul 7, 2020 at 3:03

I'm a native English speaker and not heard it used like this as far as I can remember but if I did hear someone use it like this I wouldn't find fault with it. I did some research on this and found it used in text describing "price slabs" which means "pricing ranges" e.g., $0-500: https://support.reportgarden.com/en/articles/2002057-about-slab-based-pricing#:~:text=Slabs%20are%20adspend%20(usage)%20ranges,the%20slab%20for%20each%20range.
I think "slab" is just a generic describer of a "large-piece" of anything. It sounds a bit slangy maybe? But I think should be fine to use it in any context.
I've seen "slab" used this way occasionally, kind of in the same metaphoric sense that "slice" might be used. It's not particularly idiomatic, though.
