A number of postal services has stop accepting packages containing LiPo in them, including HK-post. Thus hobbyking is unable to send packages containing LiPo directly from HK. To work around that, hobbyking managed to arrange with Swisspost to process the shipment.

So, packages that contains above a certain limit of lipo (in terms of mah), will be sent via swisspost. They does that by doing a freight transhipment to the swisspost branch in Singapore. And from singapore it is freight to Switzerland, before it is sorted and redistributed accordingly to the destination.

For certain destinations, hobbyking uses SingPost transhipment IWC service. Same, frieght to singapore, than it is resorted and ship out.

Both services are not the usual quick and direct "ems" service. it is usually accumulated to a certain volume passing the boxes to the shipping company, swisspost/singpost
