The fastest I've heard of a China copy being made was a Golf club (Driver) by (I think) Callaway.
Released in US, flown overnight to China, copied and made and a few copies returned to the US within 3-5 days. The company couldn't believe how quickly the fakes hit the market.
The speed the Chinese can make samples is unbelievable.
