How much would it cost to send a 10kg suitcase from Beijing to the UK?

Jemma,

I calculated it on the China Post website. It costs around CNY 852. The wrapping fee and other minimum cost are not included. This is just for your reference.

I think you can visit local China Post offices in Beijing and the staff there can figure out accurately how much money you will pay for your suitcase. The fee should be the same if you send it in Beijing.

Thanks for your reply. Is this service via air? Thanks

Yes, the cost is calculated based on the transport means of plane.
