olá colega, veja por favor os dois links que lhe enviei, uma vez que não consegui "copiar" a informação do segundo... espero que lhe tenha ajudado!

What is the difference between a commercial and an exhibit batch?
A commercial batch is formulated or say manufactured at the production plant then what about the exhibit batch?

4. It is not mandatory to manufacture the Exhibit batch in the Production plant, but you must use identical/or essentially similar equipment. And this includes manufacturing vessel, transfer lines, filters, filling lines/needles, and so.
Regarding Scale-up/Exhibit batch, it is obvious that you cannot go ahead with an Exhibit batch until the Scale-up batch (including preliminary stabily) has been successful.
In relation to Exhibit/Commercial, and as mentioned before, Exhibit is the batch you will use to generate your stability data for submission and approval purposes, but please, do not intend to market this... Moreover, before you have 3 or 6-month stability data, and you have received approval, 2 years may have lapsed, so your product will be gone (assuming an initial 2-year shelf-life granted)...
This would be the main reason for not wasting material, money and time in doing a Commercial batch (x10 the size of an Exhibit), if this has to end in the bin...

5. • Exhibit batch is typically used to generate ICH stability data to submit your ANDA package, whereas commercial batches (it start with 3 validation batches) are followed later which are used to validate the process and you can sell FP from validation batches once ANDA application is approved.
