Quick answer
A U.S. SDS does not have a blanket annual renewal date under federal OSHA. Significant new hazard or protective information must be added within three months of becoming known. Product changes, contact changes and regulatory transitions also need review. A customer’s document-age policy is a separate question; changing the printed date alone does not update the content.

How often do SDSs need to be updated in the US?
Use the product and new information to decide what needs reviewing. Federal OSHA does not require every SDS to be renewed annually merely because a year has passed. An old date is a reason to check the record, not proof that the product information is wrong or current.
A useful internal review asks whether the product, supplier details, evidence or applicable requirements changed. Keep the response and its basis with the product records. A periodic business review can help identify changes, but its chosen interval should not be presented as an OSHA-wide renewal period.
This guide concerns U.S. update decisions. The U.S. FAQ on yearly SDS renewal addresses the annual-renewal question without switching to another market’s pricing.
What does OSHA’s three-month SDS update rule mean?
Under 29 CFR 1910.1200(g)(5), the manufacturer, importer or employer preparing an SDS must add newly learned significant information about the chemical’s hazards or protective measures within three months. If the chemical is not currently produced or imported, the information must be added before it is introduced into the workplace again.
This is a specific update requirement. It is not a blanket allowance to supply a changed formulation with an inaccurate document for three months. Identify the changed product and the assessment needed before deciding whether the existing SDS still describes what you supply.
For the review brief, record when the information became known, its source and which product version it concerns. Ask the preparer to establish which entries are affected rather than assuming the change belongs in only one section.
Which changes should you bring for an SDS review?
| Trigger | Records to gather | Question to resolve |
|---|---|---|
| Ingredient or concentration changed | Old and revised formula references, supplier SDSs and relevant reports | Does the existing document describe the revised product? |
| New hazard or protective information | The new evidence, date received and affected product identifiers | Which conclusions or precautions need updating? |
| New name or responsible-party contact | Current label, company details and product-identity confirmation | Which identifiers or contacts need correction? |
| Supplier or raw-material grade changed | Replacement supplier records and substitution details | What evidence changed for the finished formulation? |
| Product form, use or market changed | New application, physical form and destination requirements | Is the earlier scope still suitable? |
| Buyer questions a file or its age | The submitted version and exact feedback | Is this a content issue or a recipient policy? |
These are review inputs, not automatic conclusions about classification. For brand changes, use the private-label review guide. For several grades, use the product-register guide to identify which versions are affected.
What if a customer asks for an SDS dated within the last year?
Ask whether the recipient applies a document-age policy or found outdated information. Keep their exact request. Review the current product records and provide the resulting document or clarification appropriate to that request.
If the formulation is unchanged, explain that fact to the reviewer and identify the evidence available. If information changed, keep it visible. Replacing the date on the old PDF without checking the contents gives neither the buyer nor the author a reliable review record.

Do HCS 2024 transition dates create a separate review need?
Yes. Regulatory transition work is distinct from learning new information about one product. As of 12 October 2026, OSHA’s federal HCS transition schedule is:
| Affected group | Federal compliance date |
|---|---|
| Manufacturers, importers and distributors evaluating substances | May 19, 2026 |
| Employers: necessary substance-related workplace label, program and training changes | November 20, 2026 |
| Manufacturers, importers and distributors evaluating mixtures | November 19, 2027 |
| Employers: necessary mixture-related workplace label, program and training changes | May 19, 2028 |
Check the OSHA extension notice and current standard’s dates before scheduling work. These are federal dates; confirm the applicable requirements for a workplace under an OSHA-approved State Plan. They are not recurring SDS expiry dates.
The ethanol supplier-change example connects a procurement substitution to affected formulation records.
How should you organize an SDS update?
- Identify the current file. Keep the SDS actually supplied, its revision date and the product code it covered.
- Describe the change. Record what changed, when it became known and who holds the supporting evidence.
- Compare the product versions. Distinguish a corrected identifier from a formulation or hazard-evidence change.
- Define the review scope. Confirm the products, sections and related label questions the work will address.
- Check the draft. Match the updated information to the actual product and confirm responsible-company details.
- Record the issue. Retain the revision, supporting records and recipients of the replacement version.
If a suitable finished-product SDS was never prepared, the work may be new authoring rather than an update. Follow the U.S. preparation workflow for that situation.
Example: the additive changed but the product name stayed the same
A lubricant supplier changes an additive package while keeping the same product name. The previous SDS remains in the customer portal. A review brief should identify the old and new formulation references, the updated supplier records and the affected grade.
The unchanged label does not settle whether the SDS needs revision. The assessment compares the revised product with the earlier evidence, identifies affected information and records the version issued. This is an illustrative change-management example, not a conclusion about the lubricant’s hazard class or transport status.
What should happen when the revised SDS is issued?
Make the revision date and product identity clear. Keep an internal change record connecting the reason for review, evidence used, reviewer and issued file. Distinguish the replacement from the earlier version so purchasing and customer-service teams can send the correct document.
Under the federal standard, suppliers must provide the appropriate updated SDS with the first shipment after an update, and the manufacturer or importer must also provide it on request. Coordinate that distribution with the businesses receiving the product.
Workplace access, labels and training may need attention separately. A corrected PDF in the author’s folder does not establish that the relevant users received it. The workplace-access questions help check the practical handoff.
What should you include in an SDS update enquiry?
Send the product name, current SDS version, your supply-chain role and a short change summary. Add the date the information became known, available record types, affected product count and deadline. Keep confidential formulations out of the public form.
For example: “We manufacture two lubricant grades. One additive supplier changed. We have the previous SDSs and new supplier records and need to assess which documents require revision.” The USA service guide explains how reviews and updates differ from new authoring.

Frequently asked questions
The rule concerns when the preparer becomes newly aware of significant hazard or protective information. Record when the information became known and what it concerns so the review can address the applicable requirement.
Do not treat the significant-new-information rule as a blanket grace period for reformulation. Assess whether the existing SDS describes the changed product and define the appropriate document before relying on it.
The federal rule requires the information to be added before the chemical is introduced into the workplace again. Keep the evidence and earlier document available so that review is not lost when supply stops.
No. The transition schedule concerns compliance with modified requirements for the affected groups. It is separate from product-specific update triggers and from a buyer’s document-age policy.
Identify the affected grade, its current SDS and the formulation or supplier change. List the unaffected grades separately and provide the supporting records so the review scope can be defined.

What is the SDS authoring starting price?
Standard English-language SDS authoring starts at USD $99 per defined product. Review, testing, translation, localization and complex or multi-product work require a confirmed scope and quote. For an unchanged purchased product, request its existing SDS from the supplier first; this is not a paid document-download service.
