Do I Need a New SDS?

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

Short answer

If you are asking do I need a new SDS, start with your role under the U.S. Hazard Communication Standard, 29 CFR 1910.1200. A new Safety Data Sheet is one possible outcome, not the default. Your brand, SKU, or a marketplace message does not determine your HCS role.

Work through it in this order:

  1. Identify your role under the standard.
  2. Use the correct existing document if you have one.
  3. Request the current copy if you do not.
  4. Have the responsible party fix a file or administrative defect.
  5. Have the responsible party issue a justified revision.
  6. Commission new authoring only where no compliant document exists for the product as sold.
  7. Add testing or calculation only where the evidence for classification is genuinely missing, or where a specific physical-hazard method calls for it.

Identify your HCS role first

“Marketplace seller” is not a role under the Hazard Communication Standard. The standard assigns duties to four roles, defined in 29 CFR 1910.1200(c):

  • Chemical manufacturer — an employer with a workplace where chemicals are produced for use or distribution. “Produce” is defined broadly: to manufacture, process, formulate, blend, extract, generate, emit, or repackage.
  • Importer — the first business with employees inside the U.S. Customs Territory that receives hazardous chemicals produced in other countries in order to supply them to distributors or employers in the United States.
  • Distributor — a business other than a manufacturer or importer that supplies hazardous chemicals to other distributors or to employers.
  • Employer — a person engaged in a business where chemicals are used, distributed, or produced for use or distribution.

The duty follows from that role:

  • Manufacturers and importers classify the hazards of what they produce or import and must obtain or develop an SDS for each hazardous chemical under 29 CFR 1910.1200(d)(1) and (g)(1).
  • A business acting only as a distributor has document-transmission duties under (g)(7). A business that also produces, imports, repackages, or prepares an SDS may have additional duties in that other role.
  • Employers must have an SDS in the workplace for each hazardous chemical they use under 29 CFR 1910.1200(g)(1).

One threshold question sits above all of this. The standard applies to a hazardous chemical known to be present in the workplace in a way that employees may be exposed under normal conditions of use or in a foreseeable emergency ((b)(2)), and it carries scope limits and exemptions in (b)(5) and (b)(6) — articles, certain consumer products used at consumer-level duration and frequency, FDA-regulated drugs and cosmetics in final form, food and alcohol, and others. Those limits are conditional and fact-specific, so treat them as a question for a qualified party rather than a conclusion you reach from a product category alone.

When the existing SDS is enough

If you are a distributor or an employer and the document you already hold is the correct one for the product, no new document is needed. “Correct” means:

  • It describes the product you are actually selling — same formulation and identity.
  • The product identifier links the label and the SDS. OSHA’s position is that the product name on the label and the SDS should match; product codes carried only as supplemental information do not all have to be identical as long as cross-referencing holds (Letter of Interpretation, 19 June 2015).
  • The content is accurate and reflects the scientific evidence used in the hazard classification ((g)(5)).
  • The structure follows the standard: the sixteen numbered sections in order, with mandatory content for Sections 1–11 and 16 under Appendix D. Sections 12–15 remain part of the ordered format, but OSHA has stated it will not enforce the information requirements in those four (Note 2 to (g)(2)).

A brand name on the packaging does not change this. Where a company’s trade name is recognisable to downstream users, that name can appear on the label and the SDS (Letter of Interpretation, 22 March 2013) — the responsible party is unchanged.

When to request the current copy

If you are a distributor or employer and the document is missing, stale, or you cannot confirm it is current, the route is a request, not a purchase.

  • A chemical manufacturer or importer must provide an SDS with the initial shipment, with the first shipment after a document is updated, and on request to distributors or employers under 29 CFR 1910.1200(g)(6)(i)–(iv).
  • Distributors carry the downstream transmission duty stated in 29 CFR 1910.1200(g)(7)(i)–(ii).
  • A retail distributor selling a hazardous chemical to an employer holding a commercial account must provide the SDS on request, and must post a sign or otherwise inform such employers that one is available under 29 CFR 1910.1200(g)(7)(iii).
  • Where an employer without a commercial account buys a hazardous chemical from a retail distributor that is not required to keep SDSs on file, that retailer must, on request, provide the name, address and telephone number of the manufacturer, importer or distributor from which the document can be obtained under 29 CFR 1910.1200(g)(7)(v). In that situation the retailer owes contact details, not the document itself.

OSHA has also confirmed that an employer may contact a manufacturer or distributor to request an updated SDS for a product ordered previously, and that under (g)(6)(iv) it must be provided (Letter of Interpretation, 27 July 2015).

If the manufacturer has gone out of business and you still hold stock, an employer’s job is to maintain the document it already has — not to author a replacement (Letter of Interpretation, 31 January 2013).

When a correction is enough

Some problems are defects in the document rather than reasons to replace it. Typical examples: a required Section 1 element missing, no date of preparation or last revision in Section 16, headings out of order, or a blank subheading where the standard requires the preparer to mark that no applicable information was found ((g)(3)).

The correction belongs to the party that prepared the document — the manufacturer, importer, or other responsible party. Ask them for a corrected export. Do not edit technical content yourself to make a document pass a review: altering classification or hazard statements without the underlying evidence creates a conflict with the label and the transport paperwork, and the accuracy duty in (g)(5) still sits with the preparer.

The HCS does not set a universal calendar-based expiration period. Section 16 requires the date of preparation or last revision under 29 CFR 1910.1200(g)(2)(xvi) and Appendix D. That is a dating requirement, not a review schedule; no mandatory review frequency appears in the HCS text reviewed for this page.

When a revision is required

A revision is triggered by information, not by the calendar and not by paperwork changes.

The rule is precise: where the manufacturer, importer or employer preparing the SDS becomes newly aware of significant information regarding the hazards of a chemical, or ways to protect against those hazards, that information must be added to the document within three months under 29 CFR 1910.1200(g)(5).

That three-month clock does not attach to:

  • a change of brand, trade name, or packaging;
  • a change of contact details;
  • a new SKU;
  • a formulation change by itself.

Formulation changes are governed by a different sentence in the same paragraph: the preparer must ensure the information provided accurately reflects the scientific evidence used in making the hazard classification under 29 CFR 1910.1200(g)(5), alongside the classification duties in (d). If a reformulation changes what the classification rests on, the document has to catch up to remain accurate; that does not create a separate universal deadline.

One more trigger is worth knowing but is easy to overstate. OSHA’s 2024 update to the standard phases in by material type and by role. As of 2026-08-23: manufacturers, importers and distributors evaluating substances were required to comply by 19 May 2026 — that date has passed. Employers have until 20 November 2026 for substances. For mixtures, manufacturers, importers and distributors have until 19 November 2027, and employers until 19 May 2028 — all three still ahead. Until the applicable date, covered parties may work to the previous standard, the updated one, or a combination ((j)(2)–(j)(4); OSHA compliance-date extension). If a supplier tells you a document is being revised for this reason, that is a normal transition update rather than a problem with your product.

When a genuinely new SDS is needed

Authoring from scratch is the right answer in a small number of cases.

You are the importer and received nothing compliant. The first U.S. business to import the chemical becomes the responsible party and takes on the standard’s duties, including classification. If the foreign supplier’s document does not meet the requirements, the importer is required to create one that does (Letter of Interpretation, 18 September 2018, Q2–Q4). That same letter is why a foreign-only contact block is a real defect for the U.S. market: Section 1 must carry a U.S. address and a domestic emergency telephone number, with any foreign address treated as supplemental.

You produce or repackage the product. “Produce” in the definitions includes repackaging and blending, and OSHA has treated a distributor who repackages or blends as a manufacturer (Letter of Interpretation, 15 July 1996). That letter also describes an alternative for a repackager who does not change the hazard information: obtaining the chemical manufacturer’s consent to be the designated responsible party for both the SDS and the shipping label.

No compliant document exists for the product as sold. If the only thing available is a document for a different product and no responsible party can supply the right one, formatting cannot close that gap.

Two boundaries around this branch:

  • Private label, rebranding and brand ownership do not by themselves make you the responsible party. The duty comes from what you actually do — produce, import, distribute, or employ — and from whether the standard applies at all.
  • The one-document allowance is narrow. The standard allows a single SDS for complex mixtures with similar hazards and contents, where the chemical ingredients are essentially the same and only the specific composition varies under 29 CFR 1910.1200(g)(4). It is not a rule that one document covers ordinary variants, separate SKUs, or private-label versions.

If you land here, our comparison of SDS authoring services sets out what each provider covers and where their documented limits are. One thing to understand before you buy: engaging an authoring service does not move the legal responsibility. A manufacturer or importer may list a contracted company on the label and SDS as the party to contact for additional or emergency information, but the manufacturer or importer remains the responsible party and keeps ultimate responsibility for compliance (Letter of Interpretation, 18 September 2018, Q8–Q9). OSHA has stated the same point directly — responsibility for distribution and for the quality of the information cannot be contracted out (Letter of Interpretation, 30 January 1997).

When testing or calculation enters the process

The standard does not make you send your product to a laboratory in order to classify it. The classification paragraph says there is no requirement to test the chemical to determine how to classify its hazards ((d)(2)), and Appendix A repeats that there is no requirement for testing chemicals. Classification draws on the full range of available scientific literature and other evidence.

That is not the same as “testing is never required.” Certain physical hazard determinations in Appendix B specify particular methods. Flammability of gases, for example, is determined by tests or by calculation under a named ISO standard; explosives are classified through a defined UN test-series procedure. Those are method requirements attached to specific hazard classes, and calculation or existing data may satisfy them without new laboratory work.

The practical reading: testing is a way to close a genuine evidence gap or to meet a specific method requirement — not a routine step, and not something to buy before you know which gap you are closing.

TikTok Shop acceptance is a separate check

This section is about platform policy, not U.S. law. Passing one does not settle the other.

TikTok Shop US publishes its own document rules. Its SDS guide states that sellers must submit the exact SDS for the specific product, matching the exact formulation, SKU and packaging, and that generic or self-made documents are not to be uploaded. It also expects the sixteen-section GHS format and the market’s official language. For products already listed that TikTok later identifies as dangerous goods, its dangerous-goods page describes a 90-day grace period to submit the requested document through Seller Center.

Two consequences follow. A document that satisfies the federal standard can still be refused by the platform, because the platform adds its own exact-match and file conditions. And acceptance by the platform does not establish compliance with the Hazard Communication Standard or with transport rules — it is a listing decision.

TikTok’s own material summarizes manufacturer duties broadly. Treat that wording as platform guidance rather than a statement of U.S. law: the federal duties are set by (g)(1), (g)(6), and (g)(7), and they differ by role.

If you are working through a specific request or refusal on that platform, see TikTok Shop US: SDS required or rejected.

Myths and common mistakes

“My brand is on it, so I am the manufacturer.” Branding alone does not create responsible-party status. Repackaging or blending can, because those fall inside the definition of “produce.”

“The formula changed, so the three-month clock started.” That clock runs from becoming newly aware of significant hazard or protective information. A reformulation still has to leave the document accurate against the scientific evidence behind the classification under 29 CFR 1910.1200(g)(5).

“An SDS expires after three or five years.” No universal calendar expiration appears in the text of the standard. Updates are event-driven.

“I have to get the product lab-tested.” Not for classification as a general matter, though specific physical-hazard criteria name test or calculation methods.

“One document covers all my variants.” Only for similar complex mixtures with essentially the same ingredients — not ordinary SKUs or private-label versions.

“The authoring service takes on the liability.” It can be the named contact. The manufacturer or importer remains responsible.

“The platform said it is legally required, so it is the law.” Platform policy and federal duties are separate questions.

Questions sellers ask

Do I need a new SDS just because I put my own brand on the product?

Not by itself. It depends on your role under the standard and on whether you produce or import the product. Branding alone does not make you the manufacturer.

The document looks old. Has it expired?

The standard’s text sets no calendar expiration. What matters is whether it is accurate and whether new significant hazard information has been added within three months of the preparer becoming aware of it.

The manufacturer changed the formula. How long do I have?

There is no universal deadline for formulation changes. 29 CFR 1910.1200(g)(5) requires the document to reflect the scientific evidence used in classification; its three-month rule applies to newly known significant hazard or protective information.

Can one document cover all my variants?

Only in the narrow case of complex mixtures with essentially the same ingredients. Not for ordinary SKUs or variants.

Do I have to lab-test my product?

Not to classify it as a general matter. Some physical-hazard determinations specify test or calculation methods.

The manufacturer is out of business. Do I have to write a replacement?

As an employer, maintain the most recent document you received. You do not have to author one in the situation OSHA addressed in its 31 January 2013 interpretation.

Does an authoring service become legally responsible?

No. It can be listed as the contact for additional or emergency information; the manufacturer or importer remains the responsible party.

TikTok rejected my document. Am I breaking federal law?

Not as a matter of course. Platform acceptance and legal sufficiency under the standard are separate checks.
