If you are a wholesaler and would like to participate in the QS scheme, you can register via the QS database, where you can choose an approved certification body that will perform the audit on your premises. The same applies to agencies and packing stations.
After a successful audit, the certification body enters the result in the QS database. You will then be sent the QS scheme agreement for signing. Once the agreement has been signed, you are entitled to trading/handling QS goods.
