"For example, holders who only have a few pieces of poultry must also comply with requirements for I&R and there will also be obligations for holders of animal species for which no requirements currently exist, such as bees, bumble bees and camel-like animals. The Netherlands has argued against these requirements when drafting these new regulations, but received little support from other member states and the EC. The EC indicated that it can allow Member States to grant exceptions to these obligations."

That's exactly what I was saying with "and is currently trying to arrange for exceptions." The EC could allow exceptions, but they haven't yet actually allowed for them.
