Consumables versus tools/working materials

Hello,

I have only just started, so everything is still a bit of a search. I have started as a manufacturer of imitation jewellery, from resin, among other materials.

I assume that goods such as resin, dyes, glitter, screws, etc. fall under ‘Trade Goods’. But what category do materials and tools that you reuse, such as silicone moulds, pliers, lamps, etc., fall under? These are small costs, so no investments for the time being.

Thanks in advance!
