Supplier Won't Provide an SDS? Your OSHA Duty (+ a Request Letter)

A drum, a pail, or a case of product lands on the jobsite — and there's no Safety Data Sheet in the box, no link in the email, and the supplier has gone quiet. This is one of the most common ways an otherwise-solid HazCom program develops a hole. The good news: the law is clearly on your side, and getting the sheet is a short, documentable process.

(If the chemical is already on site and in use — a gap you found in the library rather than a delivery that arrived empty-handed — the triage and inspection-day playbook is in Missing an SDS: how to close the gaps in your library.)

At a glance: Under 29 CFR 1910.1200(g)(6), the manufacturer, importer, or distributor must provide an SDS with the first shipment and again on request — and you, the employer, must obtain the SDS for every hazardous chemical you use as soon as possible if it wasn't provided. Put the request in writing, keep a copy as proof of reasonable diligence, and if the supplier still won't respond, contact your nearest OSHA office — OSHA can compel them. If a supplier won't provide a Safety Data Sheet, OSHA 29 CFR 1910.1200(g)(6) requires the manufacturer or importer to provide one on request, and requires the employer to obtain it as soon as possible; document a written request, and escalate to your nearest OSHA office if the supplier does not respond.

Whose Duty Is It? (Both of You)

HazCom splits the obligation, and knowing which half is whose is what makes your request land:

• The supplier's duty. The chemical manufacturer or importer must develop or obtain an SDS for each hazardous chemical and provide it to distributors and employers with the first shipment (1910.1200(g)(6)(i)). Distributors must pass it down the chain. And on top of that, they "shall also provide distributors or employers with a safety data sheet upon request" (1910.1200(g)(6)(iv)). There is no "we don't do SDSs" — providing one is a legal condition of selling a hazardous chemical.
• Your duty. As the employer you must have an SDS for each hazardous chemical you use (1910.1200(g)(1)), and if one wasn't provided you "shall obtain one from the chemical manufacturer or importer as soon as possible" (1910.1200(g)(6)(iii)). You don't get to shrug and blame the vendor — but a documented, good-faith effort is exactly what OSHA expects and what protects you.

The Step-by-Step

1. Confirm you actually need one. If the product is a hazardous chemical employees may be exposed to, you need the SDS. Genuinely exempt items — consumer products used no more than a consumer would (1910.1200(b)(6)(ix)), "articles," and food/drugs/cosmetics for personal consumption — don't require one. When in doubt, pursue the sheet.
2. Check the obvious sources first. The manufacturer's website, the product page, or the distributor's portal often has the current SDS as a PDF. Match the product identifier on the container exactly — a different formulation or concentration has a different sheet.
3. Send a written request to the manufacturer, importer, or distributor — citing their duty under 1910.1200(g)(6)(iv). Use the template below. Email is fine; the point is a dated record.
4. Set a short deadline and keep the record. Ask for the SDS within a few business days. Save the request and any reply. This is your reasonable-diligence file.
5. Bridge the gap safely. While you wait, get the hazard information another way (a manufacturer sheet for the identical product, or a reputable SDS database) so workers aren't handling an unknown. Note that a substitute sheet is a stopgap, not your compliant copy.
6. Escalate to OSHA if ignored. If the supplier still won't provide the SDS, OSHA's guidance is to contact your nearest OSHA area office. OSHA can require the manufacturer to furnish it. Your documented requests show you did your part.

What if the manufacturer is out of business?

Sometimes there is no one left to ask — the product is discontinued or the maker has folded. OSHA still expects you to have the hazard information; you just get it from the best available source and document why the original isn't obtainable. Pull the SDS for an identical or equivalent product from another manufacturer or a reputable SDS database, keep a note that the original supplier is defunct (with your search trail), and — if you still can't establish the hazards with confidence — stop using the product until you can, or substitute one you are able to document. A chemical you can't characterize is one you can't train on, label, or protect against.

Copy-Paste: SDS Request Letter

Keep a copy of the sent letter and any response in your HazCom file. If you send it by email, that timestamp is your record; if by mail, use a method with delivery confirmation.

What Not to Do

• Don't just leave the chemical unlabeled and unsheeted in use. That's the citation an inspector writes on sight.
• Don't file an SDS for a different product because the names are close. Match the product identifier exactly.
• Don't treat "the vendor never sent it" as a defense. The duty to obtain it is also yours (1910.1200(g)(6)(iii)) — but a documented request trail turns a missing sheet into a defensible good-faith effort.
• Don't stop at an outdated sheet. Use it as a stopgap while you pursue the current one (1910.1200(g)(5)).
