There is no single worldwide rule saying every MSDS expires after three or five years. Update it when product composition, supplier details, hazard evidence, exposure limits, classification or applicable requirements change. Buyers may also apply their own document-age policy.
Does an MSDS have a fixed expiry date?
No single expiry period applies everywhere. An SDS can remain current until its information is superseded, but the applicable law, buyer, marketplace or internal EHS system may require periodic review.
An OSHA interpretation on SDS accuracy and dates explains that the document remains valid until its information is superseded. A preparation or revision date is still important because users need to judge whether the information reflects current knowledge.
Which changes require an SDS review?
| Change | Why review is needed |
|---|---|
| Formulation or concentration | The hazard classification or disclosed ingredients may change. |
| New hazard evidence | Health, physical or environmental conclusions may no longer be current. |
| Physical-property change | Flash point, pH, viscosity or physical state may affect precautions or transport review. |
| New supplier identity | Section 1 and emergency contact information may need revision. |
| New intended market | Language and jurisdiction-specific requirements may differ. |
| New package or product form | An aerosol, refill, concentrate or two-part kit may present a different scope. |
| Regulatory change | Classification criteria, exposure limits or required wording may be updated. |
Do all countries use the same SDS update period?
No. For example, current U.S. OSHA enforcement guidance states that manufacturers or importers who learn significant new hazard information must update the SDS within three months. Canadian WHMIS supplier guidance uses its own significant-new-data requirements and update periods.
These examples should not be copied as a blanket Indian expiry rule. The destination market and specific product obligations must be checked.
How can you tell whether an old MSDS needs correction?
- The product or manufacturer name no longer matches the label.
- The document does not use a recognisable 16-section structure.
- Composition ranges conflict with current formulation records.
- Critical properties are missing, unsupported or copied from ingredients.
- Section 14 contradicts the product data or shipment documents.
- The revision date is old and there is no change history.
- The buyer asks for a different language or market version.
Use MSDS Rectification when the existing file has factual or structural errors.
What should a clear revision record contain?
Section 16 should identify the preparation or revision date and can summarise important changes. Keep the earlier file, product evidence and reason for revision in the internal record so the business can explain what changed.
Can a buyer reject an SDS only because it is old?
Yes, a buyer or platform may apply a document-age policy even when no universal expiry rule exists. Ask whether the concern is simply the date or whether the reviewer found a mismatch, missing section or outdated classification. Updating only the printed date without reviewing the data is not a valid correction.

Frequently Asked Questions
No. Three years is not a universal global expiry rule. Review requirements depend on the applicable jurisdiction and requesting party.
No. A revised date should follow a real review of the product data, hazards and applicable requirements.
Review it before the changed product is supplied. A composition change can affect several sections and possibly the classification.
Usually yes for product and supplier identification, even when the formulation is unchanged.
Yes. Rectification can preserve useful information while correcting unsupported, inconsistent or outdated sections.
