We Can Assist You In Testing For These Regulations

Each company’s quality assurance program has to ensure the identity, purity, quality, strength, and composition of their products. The deadline for compliance is based on company size with all companies complying by July 2010.

USP <2232>/ USP <233>
The objective of this general chapter <2232> is to limit the amounts of elemental contaminants in finished dietary supplement dosage forms labeled as conforming to USP or NF standards. The extent of testing can be determined using a risk-based approach considering the likelihood of contamination.

California Proposition 65
The State requires that no person in the course of doing business shall introduce any CA resident to a chemical known to the State to cause cancer or reproductive toxicity without first giving a clear and reasonable warning. A list of those substances and their safe harbor levels is provided annually by the state.

USP Methodology
USP Elemental Contaminants in Dietary Supplements has been proposed and will replace USP Heavy Metals Limits Test when it is published in the Pharmacopeia Formulary (PF) and then in the National Formulary (NF). This is a proposed regulation.
