An independent group comprised of individuals from organizations involved in the life science supply chain for temperature-sensitive products has partnered to develop and publish technical guidance that defines a representative standard and drives standardization for the advancement of the industry.  In 2018 the group completed a best practice guide on the use of reusable passive thermal packaging systems which was published as a USP stimuli article in March 2019.  The group has since been developing best practice guidance on the operational qualification (OQ) process of passive thermal packaging.  In this session the latest on the OQ best practice guidance will be presented and attendees will be asked to provide live feedback on the specifics.
