Who Needs Elemental Impurities Testing

USP <232> applies to all new pharmaceutical drug products. ICH Q3D defines PDEs for 24 elemental impurities across oral, parenteral, and inhalation routes. Compliance is required for FDA and ICH market submissions.

💊

Drug Product Release

Finished drug products must demonstrate that elemental impurities — from manufacturing equipment, excipients, and water — do not exceed ICH Q3D PDEs.

🌿

Natural Source Ingredients

Botanical and mineral-derived ingredients often carry elevated background metals from soil and processing. ICP-MS verifies levels against route-specific limits.

🏭

Manufacturing Equipment

Metal leaching from reactors, columns, and filtration equipment must be assessed as part of the elemental impurity risk assessment (EIRA).

💧

Water & Excipients

Purified water, WFI, and excipients used in sterile manufacturing require elemental testing under the Option 1 or Option 2 compliance pathway.

🔬

API Characterization

New chemical entities must include an elemental impurities risk assessment in IND and NDA filings, with speciated ICP-MS data for Class 1 and 2A elements.

🧴

Dietary Supplements

USP <2232> extends the elemental impurities concept to dietary supplements. Major retailers increasingly require ICP-MS COA for Pb, Cd, As, and Hg.
