The prices of raw materials do not fluctuate directly with the labour cost of producing them.

Costs of manufactured articles importantly depend on the cost of raw materials as well as labour.

We have to find alternative ways of producing our raw materials without asking nature to do it for us.

I come from a farming culture, where we valued raw materials above all.

If raw materials pick up again, of course we have to go back to product prices. But if raw material prices are stable we will not go through to our customer.

The right raw materials can... double or triple the protective power of the immune system.
