Ho Ho, the old 3 Kg issue. It's not a Royal Mail problem, if you go to configuration > shipping and packaging > Package Tare, you'll find that by default ZC adds 3 lbs in weight to any parcel to account for "the envelope or cardboard box" what I normally recommend is that you set
Package Tare Small to Medium - added percentage:weight 10%:0
and
Larger packages - added packaging percentage:weight 8%:0
as a guideline, e.g. add 10% weight to your smaller packets and 8% for the bigger ones.
