Trademarks - What does it mean?

Hello everybody.
I precise that we are trying to get a certification for a closure system for food packaging.

We have a little misunderstanding of the points where the BCR/IOP talks about trademark!

Can someone provide me an enlightment on the point 3.7.4:

trademarks for application on the packaging materials...

Do they mean the customer trademark that is printed on the packaging should be agreed with the customer
or
do they mean that when a product sell to the customer have a special trademark (for example a patent) and the customer wants/have to inform the final customer that they use this trademark (by printing the said trademark on the package) it should be agreed with the customer?
or both :)

and approximately the same for the points 4.10.3 and 4.10.4.

Thanks by advance for any help

Trademark is a kind of certification of product which has to be printed on product for its clarity of particular product. So before buying any product check its trademark whether it is there or not.
