How should labeling change when a chemical is reformulated?

• A. Remove all hazard information to simplify labeling
• B. Retain existing labeling without changes
• C. Update hazard statements, safety data, and SDS, and re-certify labeling
• D. Delay labeling changes until the next regulatory audit

Answer: (C)

When a chemical is reformulated, the hazards associated with the product can change, so the labeling must be updated to reflect the new information. This means revising the hazard statements and precautionary statements on the label, adjusting any pictograms if needed, and ensuring the Safety Data Sheet (SDS) is aligned with the new formulation. Re-certifying the labeling also ensures that the updated label and SDS meet current regulatory requirements and internal quality standards before the product is released. Keeping old labeling, removing hazard information, or delaying updates would mislead users and create safety and compliance risks.
