Common rejection causes include incorrect supplier details, a product mismatch, missing sections, unsupported physical data, inconsistent transport information, an old revision, unreadable files or missing supporting documents. Start with the reviewer’s exact comment before changing anything.
What should you do immediately after an MSDS rejection?
Ask for the exact rejection message, checklist or marked document. “MSDS not accepted” is not enough to diagnose the problem. Confirm who rejected it, which product and shipment were reviewed, and whether the reviewer wanted an SDS, a transport declaration, a UN 38.3 test summary, a CoA or another document.
Which problems commonly cause an SDS rejection?
| Problem | What the reviewer sees | Likely correction |
|---|---|---|
| Product mismatch | The label, model, grade or formulation differs from the SDS. | Prepare or revise the document for the exact supplied product. |
| Missing supplier identity | Section 1 lacks usable manufacturer or supplier information. | Verify the responsible party and contact details. |
| Incomplete sections | Required headings or subheadings are blank or absent. | Use the applicable 16-section structure and state when information is unavailable. |
| Unsupported values | Flash point, pH or density conflicts with other records. | Resolve the evidence instead of copying a convenient number. |
| Old revision | The file predates the current product or market requirement. | Review the complete SDS and record the real revision. |
| Poor file quality | The PDF is cropped, password-locked, unreadable or missing pages. | Submit one complete, searchable and legible file. |
Why may a courier reject an SDS even when all 16 sections are present?
A courier uses the SDS as one input in its transport review. Section 14 does not replace the shipper’s responsibility to classify the material, choose compliant packaging and provide any required declaration, test summary or approval.
Transport rejection can arise when the product name differs across documents, a battery lacks supporting UN 38.3 information, flash point evidence is missing, or the declared DG/Non-DG status conflicts with the formulation.
Why may a buyer or marketplace request a different document?
Some reviewers use “MSDS” as a broad label for product-compliance evidence. A marketplace may actually need an ingredient statement, product label, test report or battery document. A buyer may require a local-language SDS or its own supplier details. Confirm the requested outcome before rewriting the file.
How can you audit the rejected SDS section by section?
- Sections 1–3: confirm product identity, responsible supplier, classification and composition.
- Sections 4–8: check that emergency, handling, storage and PPE guidance matches the hazards.
- Sections 9–11: verify physical, stability and toxicology information against reliable evidence.
- Sections 12–15: review environmental, disposal, transport and regulatory statements for the intended market.
- Section 16: confirm revision date, change record and document scope.
OSHA Appendix D requires specified SDS information and says unavailable information should be identified rather than silently omitted.
When should you rectify the SDS instead of preparing a new one?
Rectification is appropriate when the existing document belongs to the correct product but contains missing, inconsistent or outdated content. Prepare a new SDS when the formulation, component, product form or responsible supplier is materially different.
Use the MSDS Rectification service and submit the rejected file together with the reviewer’s message.
An old revision is only one possible reason for rejection. Use the separate guide on MSDS validity and update triggers before changing the document date.

The rules quoted below belong to their respective jurisdictions. They explain the cited principle and should not be treated as one universal requirement for every product or country.

Frequently Asked Questions
Possibly, but ask for the exact policy. A stamp alone does not correct product, classification or supporting-document problems.
Not without evidence. Transport information must be reviewed from the actual product, test data and applicable rules.
Yes. Missing and inconsistent sections can often be rectified when reliable product information is available.
The marketplace may need a different document, local supplier details, a newer revision or evidence beyond the SDS.
Send the rejected SDS, reviewer message, current product label, formulation and supporting technical documents.
