jovialz: here is the reply from my supplier. But before this reply, he said that the car seat is approved with the European Standard. For me to get the cert, I need to pay for $50. So I asked him whether we need to supply the cert to show traffic police or maybe the standard is printed in the car seat. Below is his reply:
It is Portable baby car seats, not real baby car seats. Portable baby car seats do not need certificate, because it is only as accessories to enhance security.
You can think, if parents do not use portable baby car seat, their baby or kids also can sit on car. But why when they use portable baby car seat, their baby or kids can sit on car when portable baby car seat has certificate ?
All in a word, portable baby car seats do not need certificate, because it only as accessories to enhance security. If parents do not think they are necessary, they can put their kids on car without it. But if without it, the security is lower.
I feel my explain is too confuse, hope you can understand and forgive my poor English.
Does it make sense? hahahaha. I'm confused myself...
