Misbranded is the legal term for non compliant with FDA regulations.
A misbranded product could be detained by the FDA and U.S. Customs at any U.S. port or airport.
Your product may be detained because it appears to be:
■ adulterated – the product is contaminated, is not safe, or does not otherwise meet applicable standards
■ misbranded – the labels contain false or misleading information
■ an unapproved new drug
■ manufactured, processed, or packed under insanitary conditions
■ forbidden or restricted for sale in the country in which it was produced or from which it was exported.
