21 CFR Part 1271 Regulatory Education & Compliance Resource Center
This resource center provides structured educational materials describing the United States regulatory framework governing Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps) under 21 CFR Part 1271.
These materials are intended to support regulatory literacy for licensed healthcare professionals, institutional operators, compliance reviewers, and organizations evaluating regulatory classification within the HCT/P framework.
Topics covered include minimal manipulation (21 CFR 1271.3(f)), homologous use (21 CFR 1271.3(c)), donor eligibility determination (Subpart C), and current good tissue practice (Subpart D).
For a structured overview of the complete regulatory system governing HCT/Ps, begin with the primary framework page below.
Qualification under Section 361 requires satisfying regulatory criteria defined within 21 CFR 1271.10(a), while products that do not meet these criteria may be regulated under Section 351.
