The new and improved CCIA website will be launched on Tuesday, January 22nd! We hope you will find it easy to navigate and find the information needed. Once you login as a member the site will continue to look the same as it does now. That portion of the site will be updated later this year.

Certification and OECD Tag Requests

All tags for certified seed are now requested using an online tag request procedure that will provide most of the information about the seed lot. You will need to log in as a member to use this system.

Use this link for Tag requests

Tag request information:

  • Tag requests will be printed in the order they were received during the hours of 7:30 am to 3:00 pm, Monday thru Friday, unless otherwise notified.
  • Tag request turnaround time is between 24 to 48 business hours.  However, the CCIA strives to complete all tag requests on the same day received whenever possible.
  • Tag requests that contain inaccurate or incorrect information will cause delays!
  • Overnight orders cannot be guaranteed unless they have been submitted before noon the previous day.
  • Conditioners who wish to pick-up their tag orders in person will be notified by CCIA Staff when the tags are ready and available.  Please note that the 24 to 48 hour turnaround time applies for all pick-up orders as well.
