Hey, what kind of equipment is it? Cars? I recently had to ship spare parts for laboratory equipment from Singapore to New Jersey. First, I checked which international carriers were available, then I read everything I could find. Gettransport
https://gettransport.com/shipping/from-singapore-to-united-states did a great job of explaining how long you'll have to wait for the different shipping methods. If your customer is in a hurry, it's better to splurge on air shipping. Also, if the equipment is specific, it's better to check Singapore's customs rules, prohibited items, etc. , so there are no surprises.
