International Clients

The United States will observe the New Year holiday on Monday, Jan. 1. On this day, Mayo Clinic Laboratories will be open; however, sample shipments and deliveries to our laboratories will not be made by the carriers.

To safeguard your samples, we strongly recommend the following guidelines for international shipments except for clients in Saudi Arabia:

• For shipments with a one-day transit time, do not ship on Saturday, Dec. 30 or Sunday Dec. 31.
• For shipments with two or three-day transit times, do not ship on Thursday, Dec. 28 or Friday, Dec. 29, as these shipments could incur potential delays per U.S. Customs and operations. They may not be delivered until Wednesday, Jan. 3 or later. Please hold irretrievable samples in stability.
