***Cold Treatment Vessel Expiration Extension***

Due to continuing concerns with Covid-19 and available resources, APHIS-PPQ will extend certification expiration dates for all eligible cold treatment (CT) vessels. All vessels with certification expiration dates between March 17, 2020 and April 29, 2023 will now have a new expiration date of April 30, 2023. Vessels with expiration dates before March 17, 2020 will still require recertification to participate in U.S. in-transit break bulk cold treatment programs (at this time, recertifications services are only available in the U.S.). These changes will not affect vessels with expiration dates after April 30, 2023. Please send all questions to
