Manufacturer SDS vs Authored SDS: Which Do You Need?

Scope: United States, OSHA Hazard Communication Standard. Reviewed 2026-08-23.

Short answer

Manufacturer SDS vs authored SDS: start with the exact, current manufacturer or supplier document. If it exists and matches the product as sold, there is no reason to commission a replacement solely for marketplace submission.

Paid authoring is justified only when no correct exact-product document exists and the preparation duty belongs to you. Your brand, SKU, packaging, or a marketplace rejection does not decide that duty by itself.

Keep three questions separate. Legal duty under the U.S. Hazard Communication Standard, factual product-to-document match, and marketplace acceptance are different tests. Platform acceptance alone does not establish HCS compliance, and platform refusal alone does not establish a violation.

What counts as an exact manufacturer SDS

A manufacturer or supplier SDS is usable only when it genuinely describes the product you sell:

The product identifier matches. OSHA requires the identifier on the label and in Section 1 of the SDS to correspond. If a product code is used as the identifier, it must match too. See OSHA’s 19 June 2015 interpretation.
The formulation is the same as the formulation covered by the document.
The structure is complete. The SDS follows the sixteen-section order required by 29 CFR 1910.1200(g)(2), with mandatory content described in Appendix D.
The content is accurate. Under 29 CFR 1910.1200(g)(5), the preparer is responsible for ensuring that the SDS reflects the scientific evidence used for the hazard classification.

A recognisable trade name may appear on both the label and SDS when it still allows downstream users to identify the same company. Branding alone does not disqualify the manufacturer’s document. See OSHA’s 22 March 2013 interpretation.

Use this decision tree

Establish your HCS role. “Marketplace seller” is not a role in the standard. Duties attach to chemical manufacturers, importers, distributors, and employers.
Does a current exact-product SDS exist? If yes and the identity and content match, use it.
Is the current copy simply missing? Request it from the manufacturer, importer, or supplier.
Does the correct document contain an administrative or supported content defect? Ask the responsible party to correct it.
Has significant hazard or protective information changed? The responsible party may need to revise the SDS.
Does no correct document exist, and are you the party that owes one? New authoring may be justified.
If a contractor writes it, responsibility does not move to the contractor.

Start hereUse the existing SDSWhen an exact, current document already covers the product as sold.

Missing copyRequest the current SDSWhen the document exists but is not in your files or you cannot confirm the version.

Document issueCorrect or reviseWhen the responsible party needs to fix supported content or add new significant hazard information.

Narrow paid routeCommission authoringWhen no correct document exists and your actual HCS role requires you to prepare one.

When to use or request the manufacturer SDS

If the exact document exists but is not in your files, the route is a request, not a purchase:

29 CFR 1910.1200(g)(6)(iv) directs a chemical manufacturer or importer to provide distributors or employers with an SDS upon request.
If a shipment arrives labelled as hazardous without an SDS, (g)(6)(iii) directs a distributor or employer to obtain one from the manufacturer or importer as soon as possible.
Paragraph (g)(7) places the downstream transmission duty on distributors for initial shipments and the first shipment after an update.

OSHA has confirmed that an employer may request an updated SDS for a product ordered previously and that (g)(6)(iv) requires the manufacturer or importer to provide it. See the 27 July 2015 interpretation.

Include the label’s exact product identifier and enough detail to distinguish the formulation and package you sell.

When correction or revision is enough

A document may need a correction without needing to be replaced. Examples include a missing Section 1 item, a missing preparation or revision date in Section 16, headings out of order, or a blank required subheading where the preparer should state that no applicable information was found.

The responsible party should make that correction. Do not rewrite technical classifications or hazard statements merely to pass a platform review.

Revision is triggered by information, not by the calendar. If the manufacturer, importer, or employer preparing the SDS becomes newly aware of significant information about a chemical’s hazards or ways to protect against those hazards, 29 CFR 1910.1200(g)(5) gives the preparer three months to add it.

The HCS does not set a universal calendar expiration date for SDSs. A brand, packaging, contact-detail, or SKU change does not start the three-month clock by itself. A formulation change still matters when it changes the scientific evidence or classification that the SDS is expected to reflect accurately.

When a newly authored SDS is justified

Authoring from scratch fits a small set of situations:

You produce, blend, or repackage the product

The standard defines “produce” broadly. It includes manufacturing, processing, formulating, blending, extracting, generating, emitting, and repackaging. OSHA has treated a distributor that repackages or blends as a manufacturer. Its 15 July 1996 interpretation also describes an alternative where a repackager that does not change the hazard information obtains the original manufacturer’s consent for the manufacturer to remain the designated responsible party on both the SDS and label.

You import and receive no compliant U.S. document

The first U.S. business to receive an imported chemical is the importer and responsible party. If the foreign supplier does not provide an HCS-compliant SDS, OSHA says the importer must create one. Section 1 must include the importer’s U.S. address, while a foreign manufacturer’s address may be supplemental. See the 18 September 2018 interpretation.

You alter required information or voluntarily adopt a replacement

A distributor that changes required label or SDS information assumes responsibility for the changed content. If a manufacturer has gone out of business, OSHA says an employer should maintain the most recent SDS it received; the employer is not required to create a replacement. If it voluntarily prepares one, it becomes responsible for that document. See OSHA’s 31 January 2013 interpretation.

Who stays responsible when a contractor writes it

Responsibility cannot be contracted out. A specialist may draft the SDS or serve as a contact for additional or emergency information, but OSHA states that the manufacturer or importer retains ultimate responsibility for HCS compliance.

OSHA’s 30 January 1997 interpretation says responsibility for SDS distribution and information quality remains with the manufacturer, importer, or distributor. The 2018 interpretation adds that a contracted author may be listed as a contact, but does not take over the underlying duty.

Manufacturer, revised, and authored SDS compared

Question	Exact manufacturer SDS	Corrected or revised SDS	Newly authored SDS
What is it?	The maker’s existing document for the exact product.	An update to an existing document by the responsible party.	A document prepared where no correct exact-product SDS exists.
When does it fit?	The document is current and identity, formulation, and content match.	The existing document has a supported defect or requires an event-driven update.	Your actual HCS role requires a document and no correct one can be obtained.
Who is responsible?	The manufacturer, importer, or other responsible party named for it.	The responsible party that prepares or adopts the revision.	The manufacturer, importer, employer, or other responsible party that prepares or adopts it; a contractor may draft but does not take over the underlying duty.
What does it solve?	Exact-product sourcing without an unnecessary authoring purchase.	Accuracy and currency without unnecessary re-authoring.	Creates a defensible document where none exists.
What does it not solve?	A mismatch in formulation or identity.	A situation where no exact-product basis exists.	It does not guarantee marketplace acceptance or transfer legal responsibility.

What private label, a new SKU, or rejection do not prove

Private label or a new brand. Branding alone does not determine who produced, imported, or altered the product. OSHA has not published an interpretation that resolves every private-label or contract-manufacturing arrangement by name. Where the specification owner and physical producer differ, establish the parties’ actual roles instead of relying on the brand printed on the package.

A new SKU or product code. The decisive point is whether the identifier still cross-references the label and SDS and whether the document covers the same formulation.

A packaging change. Packaging alone is not the (g)(5) trigger. Repackaging can, however, affect your role under the definition of “produce.”

A marketplace rejection. It proves that the platform refused a file; it does not establish a federal violation or a duty to buy a new document.

Platform rules are a separate check

This section describes TikTok Shop US policy, not U.S. law. The federal duties come from the Hazard Communication Standard and depend on role. Platform rules govern whether a marketplace accepts a submission.

TikTok Shop US says its SDS submissions should match the exact formulation, SKU, and packaging, use a sixteen-section GHS format, and identify the product consistently with the listing and label. Its guidance rejects generic, self-made, and similar-product documents. That policy pushes sellers toward the exact manufacturer or supplier SDS when one exists.

TikTok also describes a 90-day grace period for an already-listed product that the platform later identifies as a dangerous good. Confirm the deadline shown in your own Seller Center; do not assume it applies to a new blocked listing or every rejected file.

For a platform-specific diagnosis, see TikTok Shop US: SDS required or rejected.

Current HCS transition dates

As of 2026-08-23: for substances, the manufacturer/importer/distributor date of 19 May 2026 has passed, while employers have until 20 November 2026. For mixtures, manufacturers, importers, and distributors have until 19 November 2027, and employers until 19 May 2028. Until the applicable date, covered parties may follow the previous standard, the updated standard, or both. See OSHA’s compliance-date extension.

A supplier may reissue an SDS during this transition. That does not mean a seller should commission a separate document.

Common mistakes

“My brand is on it, so I have to author one.” Branding alone does not create the duty. Producing, blending, repackaging, or importing can.
“The SDS is five years old, so it expired.” The HCS has no universal calendar expiration date. Ask whether the document is still accurate and current for the product.
“I need lab testing before anyone can write it.” The HCS does not impose a general testing requirement for classification. Certain physical-hazard criteria in Appendix B specify test or calculation methods.
“The authoring service becomes responsible.” A contractor may draft or serve as a contact; the underlying HCS duty remains with the responsible party.
“TikTok rejected it, so it is not compliant.” Marketplace acceptance and federal compliance are separate tests.

Questions sellers ask

Can I use my supplier’s SDS when my brand is on the product?

Possibly. The exact-product match, formulation, product identifier, and the parties’ real HCS roles matter more than branding alone. Confirm that the document covers the product as sold.

Can I ask the manufacturer for the current document?

Yes. 29 CFR 1910.1200(g)(6)(iv) requires a manufacturer or importer to provide an SDS to distributors or employers on request. Use the exact identifier from the label.

My contract manufacturer uses my recipe. Who authors the SDS?

That depends on who actually produces, imports, repackages, or adopts the document. OSHA’s published interpretations do not resolve every contract-manufacturing arrangement as a category. Get qualified advice if the allocation is unclear.

The manufacturer changed the formula. Do I need a new SDS?

Accuracy remains the responsible party’s duty. A revision may be enough. The three-month rule applies when the preparer becomes newly aware of significant hazard or protective information.

Does buying an authored SDS make the product compliant?

No. It creates a document. Compliance depends on role, accurate classification and content, and the duties that accompany the product. Marketplace acceptance also remains a separate decision.
