"In follow-up to the sold-out webinar we hosted on October 29^th, this one hour live question and answer session will address the volume and variety of questions we received not only during the event, but also in follow up from a large number of clients," noted Ronak Patel. "This open format event offers an opportunity to receive feedback from the CSA Team on anything related to the changes to the USP 661.1 / 661.2 chapters and how they will affect your current and future plastic-based package systems."

As a reminder, the changes to these chapters go into effect December 1, 2025. USP 661.1 is designed to characterize the materials of construction for a packaging system while the USP 661.2 chapter is specific to the actual plastic components used in the packaging system. During this open format Q&A Session, the following key topics will be covered:

• How USP 661.1 and 661.2 apply to packaging and container systems, including their plastic materials of construction
• Current challenges and practical approaches to overcome them
• Applicable tests and sample requirements for both material and system-level evaluations
• Responsibility for data generation - understanding who is responsible for obtaining and maintaining compliance data
• Any specific questions you may have related to your packaging system or plastic materials - whether it involves a common configuration, a novel system, or new materials of construction
