Try to import from USA within a container with partial shipment. It saves you from lots of expense. Singapore is one of the largest port in the world and they have a big infrastructure. If the shipper send with a forwarder , forwarder can rip you when they give you the bill of lading. So ask the shipper to learn every cost to you. Its hard , time consuming but cheap.
An Sax cost you to ship from China to Istanbul 125 dollars with UPS but shipment of a motorcycle from sea cost you 15 dollars.
