Here’s a quick overview.

A Biological Material is a naturally occurring material containing genetic information and capable of reproducing itself or being produced within a biological system. This Special Condition addresses biological materials still in their original form, and not biobased chemical derivatives.

Biological materials are a Special Condition because they are complex mixtures of variable or unknown composition that cannot be broken down by CAS number but may have distinct hazard profiles.

The Special Conditions guidance identifies how to notate Biological Materials on an HPD using the term “SC:Bio,” and how to categorize each substance, such as Tree-based, Animal-based, Live microorganisms, and other options. Manufacturers completing HPDs for products containing Biological Materials may enter additional detailed information in the Notes.

This is just a summary; detailed information is available in HPDC’s Emerging Best Practices guidance.
