I'm sure there are many options as far as shipping companies. Don't rule out Hong Kong based companies as they speak English and can help with the customs issues.
Beware of sending them direct via the manufacturer. I bought a pair of Vandersteen's direct from Vandersteen and they were sent through China Eastern cargo and it was a mess for me. They wanted me to send them back to America and then re-ship them via a different carrier. "China customs issues". Ask about customs issues with the importers. Luckily my wife is a Chinese government official and we resolved the problem with a bottle of Scotch and a carton of cigarettes.
Good Luck
