US Shipment

Samples collected for MBTs need to be shipped on ice (or blue ice) for next day delivery (See below for Saturday delivery instructions). If regular ice is used, the ice should be double bagged to ensure no sample contamination occurs. Please label each sample using a permanent marker and package firmly to prevent spillage or breakage.

Key Points to Remember When Sending Samples

  • Always package samples securely to prevent breakage/spillage
  • Always include enough ice to keep samples around 4°C (especially during summer months)
  • Please have a completed COC form with all the necessary information for both reporting & invoicing; if you are unsure of the analyses information please contact us.
  • Make sure all samples are labeled correctly and correspond with the COC form
  • Make sure if sending samples for Saturday delivery that they are FedEx marked for Saturday delivery, and shipped to the FedEx location at Murdock Rd, Knoxville, TN not our business address.

MI Sample Cancellation Policy

MI understands that on rare occasions our clients may want to cancel an order or individual samples.  However, because samples are processed promptly upon receipt the following cancellation surcharges will apply. If cancellation is within 24 hours of sample receipt there will be no charge. If cancellation is requested 24 hours up to 3 working days there will be a 50% surcharge to cover our processing to that point. After 3 working days the full charge will apply.
