Energy Balancing in A3

Hello

I am modelling the manufacture of a ceramic product where some of the raw materials (e.g. coke) is fully combusted in A3. I believe this is a raw material (as opposed to ancillary material) as it is physically incorporated within the product. Regarding energy balancing, would I be correct to manually balance this in A3? It seems illogical that this combustible material should be balanced in End of Life as per the standard balancing guidance.

Thank you.
