Please find the attached comparison cost and transit time for the courier service from China to Korea for DHL; FedEx; UPS and Speed post. The most expensive is DHL, but it is fast and safety; the costs are acceptable for FedEx and UPS and the transit time is also ok for both couriers. Speed post is lower cost, but the transit time is so long. Please advise me your final decision, which courier you prefer use in the future.
