How much to ship a 25kg parcel from China to Sydney by surface mail?

Dave, each parcel should not weigh over 20kg. Maybe you need to divide the items into 2 packages and the fare for a 20kg parcel is CNY370 and a 5kg parcel is CNY150. If it cannot be separated, you should deliver it as a cargo and the cost for a 20GP container is CNY2,000 for your reference.
