The American Herbal Products Association (AHPA) has published slack-fill guidance to help the regulated supplement industry inform consumers and comply with all relevant federal requirements.

The difference between the capacity of a container and the volume of product inside is known as "slack-fill." The Food and Drug Administration (FDA) regulates how food (including dietary supplement) containers are filled to packaging that could mislead consumers about the quantity of a product they are purchasing.

AHPA's guidance provides best practices for industry to help companies ensure that packaging accurately informs consumers about the quantity of product in containers and comply with relevant federal regulations. The guidance provides an overview of slack-fill laws and regulations, a discussion of practical considerations and exemptions for packagers of food and dietary supplement products, and answers basic questions about compliance with federal slack-fill regulations.

Among other topics, the guidance explores:

  • When slack-fill is "misleading?"
  • How much empty space is too much?
  • Use of transparent panels and windows
  • Functional slack fill exemptions
  • Unavoidable product settling during shipping and handling

"A number of factors, often outside a company's control, can cause a gap between a package's capacity and the actual amount of the product inside," said AHPA President Michael McGuffin. "It is important for companies to understand these factors and what they can do to mitigate them so customers know how much product they are purchasing."

The book is available in hardback print and online formats.

Some of these relate to its operation, as it allows subscribers to search for keywords and botanical names and easily access the information they use most by saving personalized lists of entries. Perhaps more importantly, the online version will be updated regularly with new research, and subscribers will be notified of updates to provide immediate access to the most current information. The standard retail cost for either version is $119.95 (one-time cost in print; a renewable annual subscription online). We are discounting the cost for our members and would be happy to offer a discount to other organizations. A free preview of several entries are available online:
