It is you and your buyer who agree on which levels in your product hierarchy that need quality assurance. Validoo quality-assures the levels you make a booking for. Physical product samples that weigh more than 15 kg can not be received, and therefore it is not possible to book quality assurance of measurements for example a pallet.
In general, it is a good idea to quality-assure the orderable level in the trade item hierarchy and all levels below.
For example: You are supplying cartons with juice to your customers, and each carton contains a certain number of three-packs with juice. For complete quality assurance of the trade item information, you need to place orders on the carton (provided it does not weigh more than 15 kg), the three-pack and the consumer packaging.
