Many Chinese dropshippers will have disclaimers on their websites about shipping time. The average time for dropshipping from China is about ten days, give or take. It all depends on the items you ordered, the size of the order and where you are shipping to.

Before committing to dropshipping with a company, I suggest you order a sample of whatever item you are going to be dropshipping. You will then be able to get the best estimate of the time it will take to dropship those items from China.
