Hi mate,
Great items for sale there. No you're not breaking any rules.
One point though... I'd suggest trying to find an international shipping method. Our members map doesn't show anyone from China and I doubt there are many with shipping addresses there.
It works for US only and a bit less so for EU only and AU only as we have many members from there, but I doubt we have many from China.
PS: What customs policies? I bought dozens of knives from China (as well as tons of stuff you can bearly get out of other countries: computers, firecrackers, Lithium batteries, shivs, knuckles, automatic knives, various chemicals, live pets, tritium etc.)
