Thanks everyone for your replies!
I was actually wondering how the CFS would be used. So lets say I put the Device Model as brief description, slightly different from that shown on the product packaging and product catalog, excluding the REF no. Would that be okay?
eg: Instead of [Urine Bag 3L, 30cm, NRV Valve, Large Pack] I put [Urine Bag]
This is requested by Thai authorities. And I am not sure if they are going to cross check the exact description of the goods and REF no with the schedule listed on the CFS.
According to MHRA, the contents on listed on the Schedule is dependent on the requirements of the regulatory authorities to whom you are exporting to.
