When Do You Need to Update Your SDS? A Complete Guide

Your SDS isn't a one-time document. It's a living record of your product's hazards, and it needs to change when the product changes, when the science changes, or when the rules change. Here's how to know when an update is required, and when it's simply a smart idea.

When an update is legally required

Under OSHA's Hazard Communication Standard (29 CFR 1910.1200), you must update your SDS whenever new and significant information becomes available about the hazards of the chemical, or about the protective measures required to handle it safely. In practice, that means:

• A change to the formulation, including a new or removed ingredient, a supplier change, or a concentration change
• New hazard information, such as a newly identified health effect or a revised classification
• New protective measures or control recommendations
• A change in the regulatory status of an ingredient, including a new Prop 65 listing or a revised exposure limit
• Corrections to errors in the existing SDS

Manufacturers and importers are generally expected to act promptly, and many international frameworks (including the EU's REACH regulation) set a specific deadline, typically within three months of becoming aware of significant new information.

When an update is best practice, even if nothing changed

Even if your formulation and the science haven't changed, your SDS can drift out of date:

• The regulatory landscape shifts. Exposure limits, classification criteria, and warning requirements are updated regularly.
• Your markets change. An SDS built for the U.S. won't satisfy Canada, the EU, or the UK without adjustment.
• Your customers require it. Many distributors and platforms expect an SDS reviewed within the last three years, and some require annual confirmation.
• Your label changed. If the label and the SDS no longer agree on hazards, pictograms, or statements, one of them is wrong.

A practical rule of thumb: review at least every three years, and re-verify whenever anything about the product, the supply chain, or your target markets changes.

What a good update process looks like

1. Keep a current formulation and supplier record for every product.
2. Track regulatory changes in each market you sell into, including Prop 65, REACH, and state-level VOC rules.
3. Review the SDS whenever the label is revised, so the two stay aligned.
4. Date and version every revision so you can show a clear history.
5. Store the current SDS where employees and customers can actually find it.

The bottom line

The question isn't only "did something change?" It's "can I show that this document reflects my product as it is today, in the markets I sell into?" If the answer is anything other than a confident yes, it's time for a review.
