GHS Label Requirements: The 6 Required Elements (and What Isn't Required)

Pick up any container of a hazardous chemical that a manufacturer shipped to your business — a drum of solvent, a case of aerosol cleaner, a jug of degreaser — and look at the label. Under OSHA's Hazard Communication Standard, that label has to carry six specific pieces of information. Not five, not "whatever the manufacturer felt like including." Six required elements, spelled out in 29 CFR 1910.1200(f)(1):

1. Product identifier
2. Signal word
3. Hazard statement(s)
4. Pictogram(s)
5. Precautionary statement(s)
6. Name, U.S. address, and U.S. telephone number of the manufacturer, importer, or other responsible party

That's the whole list. Most small business owners never audit the labels coming through their door — they assume that because a big supplier printed it, the label must be compliant. Usually it is. But when a label is missing an element or carries the wrong one, the gap becomes your problem the moment an OSHA inspector walks the floor. This guide covers each of the six elements and where it comes from, the items people think are required but aren't, how the rules change for small containers and for the labels you make in-house, and a thirty-second check you can run at the receiving dock.

Two Kinds of Labels — Don't Confuse Them

Before the six elements, one distinction that trips people up constantly.

Shipped-container labels are the labels a chemical manufacturer, importer, or distributor puts on a container before it leaves their facility. These are the full GHS labels, and they must carry all six required elements. This is what 1910.1200(f)(1) governs, and it's what most of this article is about.

Workplace labels are the labels you apply to containers inside your own facility — usually when you pour a chemical into a secondary container. OSHA gives employers a choice here. Under 1910.1200(f)(6), your in-house label can either (i) reproduce the first five shipped-label elements — everything but the supplier block — or (ii) carry just the product identifier plus "words, pictures, symbols, or combination thereof" that give at least general information about the hazards, as long as your written program and SDS access fill in the specifics. That reduced option is why the secondary container labeling rules look so different from the six elements below.

The Six Required Label Elements

Here are the six elements every shipped GHS label must carry, in the order the standard lists them in (f)(1).

1. Product Identifier

The product identifier is the name or number used to identify the chemical. It's the anchor that ties the label to everything else — most importantly, it must match the product identifier on the corresponding Safety Data Sheet exactly. If the label says "Acetone, Technical Grade" and the SDS says something different, a worker can't reliably connect the container to its hazard information.

For a single-ingredient product this is usually the chemical name. For a mixture, it's typically the manufacturer's product name or code. The one rule that matters: label and SDS have to use the same identifier so anyone can move from the container to the full data sheet without guessing.

2. Signal Word

The signal word is a single word that tells you the relative severity of the hazard at a glance. OSHA's standard uses exactly two:

• "Danger" — used for the more severe hazard categories.
• "Warning" — used for the less severe categories.

Only one signal word appears on a label. When a product has multiple hazards that would call for different signal words, "Danger" always wins — Appendix C.2.1.1 says that if "Danger" is included, "Warning" shall not appear. If a product's hazards are all mild enough that no signal word is assigned, the label simply has none.

3. Hazard Statements

A hazard statement is a standardized phrase assigned to a specific hazard class and category that describes the nature of the hazard — for example, "Highly flammable liquid and vapor," "Causes serious eye damage," or "May cause cancer." These aren't free-form. The exact wording is dictated by the chemical's classification under Appendix C, so the same hazard produces the same statement on every compliant label, regardless of manufacturer.

A product with several hazards carries several hazard statements. All applicable hazards must be conveyed — Appendix C.2.2.1 lets a manufacturer combine statements "to reduce the information on the label and improve readability," but only "as long as all of the hazards are conveyed." A manufacturer can't cherry-pick the ones that sound less alarming.

4. Pictograms

Pictograms are the red-bordered diamond symbols that communicate hazard type without words. The GHS defines nine; OSHA requires eight of them — health hazard, flame, exclamation mark, gas cylinder, corrosion, exploding bomb, flame over circle, and skull and crossbones. The ninth, the environment symbol (dead tree and fish), is not required under the HCS because, in OSHA's own words, "environmental hazards are not within OSHA's jurisdiction."

Appendix C.2.3.1 fixes the format: "a square set at a point" with "a black hazard symbol on a white background with a red frame sufficiently wide to be clearly visible." Each pictogram appears once per label no matter how many hazard classes it covers, and C.2.3.2 is explicit that "a square red frame set at a point without a hazard symbol is not a pictogram and is not permitted on the label." For a plain-English walkthrough of what each symbol means and what to do when you see it, see GHS pictograms explained.

5. Precautionary Statements

Precautionary statements describe the measures to take to minimize or prevent harm from the chemical. They fall into four types: prevention (how to avoid exposure), response (what to do after exposure, spill, or fire), storage (how to store it safely), and disposal (how to get rid of it). Examples: "Keep away from heat, sparks, open flames," "IF IN EYES: Rinse cautiously with water for several minutes," "Store in a well-ventilated place."

Like hazard statements, these are standardized by classification. A fully loaded label can carry a long list of precautionary statements, and Appendix C.2.4.6 lets manufacturers combine or consolidate them "to save label space and improve readability" — but the core safety guidance has to be there.

6. Supplier Information

The label must include the name, U.S. address, and U.S. telephone number of the chemical manufacturer, importer, or other responsible party — that's (f)(1)(vi) verbatim. This is the accountability element: it tells you who classified the chemical and who to contact for more information or in an emergency. The "U.S." part matters. An imported chemical needs a domestic point of contact, not just a foreign manufacturer's address.

Which Label Elements Are NOT Required?

This is one of the most-searched GHS label questions — it shows up on training quizzes and certification exams — and the answer is simpler than the quiz-writers make it look. If it isn't one of the six elements in (f)(1), OSHA doesn't require it on a shipped label. The items people most often assume are required, but aren't:

• An expiration or "use by" date. Nothing in the HCS puts a date on the label. (Whether SDSs expire is a separate question with its own answer.)
• An NFPA 704 diamond or HMIS color bar. These are supplemental rating systems, allowed but never required, and they don't substitute for any of the six elements.
• The chemical's CAS number. A CAS number can be the product identifier if the manufacturer chooses, but the rule requires an identifier, not a CAS number specifically.
• First-aid instructions as a separate block. Response guidance lives inside the precautionary statements; there's no standalone first-aid element.
• A hazard rating number, route-of-entry list, or "target organ" section. Those belong to the SDS (Sections 2 and 11), not the label.
• The environmental pictogram. Required under the international GHS, not under OSHA's rule.
• The date the label was printed, a lot or batch number, or a barcode. Common, useful, supplemental.

The flip side matters too: a label that's missing any of the six — most often the U.S. address and phone number on an imported product, or a signal word dropped to save space — is non-compliant no matter how much supplemental detail it carries.

GHS Label Size Requirements and Small Containers

OSHA does not set a minimum label size, font size, or pictogram dimension. The standard's requirement is functional, not numeric: under (f)(2) the information must be "prominently displayed, and in English," and under (f)(10) workplace labels must be "legible." If a worker holding the container can read it, it's big enough.

What the standard does address is the container that's too small for a full label. The HazCom 2024 update added 1910.1200(f)(12), which works in tiers:

• First, try the full label anyway. Paragraph (f)(12) only applies where the manufacturer "can demonstrate that it is not feasible to use pull-out labels, fold-back labels, or tags containing the full label information." Booklet-style and fold-out labels are the expected solution before any reduction kicks in.
• Containers of 100 mL or less may carry a reduced label with, at minimum: the product identifier, pictogram(s), signal word, the manufacturer's name and phone number, and "a statement that the full label information for the hazardous chemical is provided on the immediate outer package."
• Containers of 3 mL or less, where any label would interfere with normal use, need no label at all — but the container "must bear, at a minimum, the product identifier."
• In both cases the outer package carries the full (f)(1) label for every chemical inside, plus a statement that the small containers "must be stored in the immediate outer package bearing the complete label when not in use."

For a small business this has a practical consequence: keep the box. If your supplier ships sample vials, dropper bottles, or cartridges under the small-container rule, the outer package is the compliant label, and the reduced-label vials are only compliant while that package is available. Throwing away the carton and storing loose vials in a drawer breaks the system the rule depends on.

When a Product Has Multiple Hazards

Real chemicals rarely have just one hazard. A common shop solvent might be flammable, an irritant, and a chronic health hazard all at once. Appendix C to 1910.1200 lays out precedence rules so that a multi-hazard label stays readable instead of contradicting itself:

• Signal word (C.2.1.1): if "Danger" applies to any hazard, only "Danger" appears — "Warning" is dropped.
• Skull and crossbones vs. exclamation mark (C.2.1.2): if the skull and crossbones is included, the exclamation mark "shall not appear where it is used for acute toxicity."
• Corrosion vs. exclamation mark (C.2.1.3): if the corrosive pictogram is included, the exclamation mark "shall not appear where it is used for skin or eye irritation."
• Health hazard vs. exclamation mark (C.2.1.4): if the health hazard pictogram is included for respiratory sensitization, the exclamation mark "shall not appear where it is used for skin sensitization or for skin or eye irritation."

These rules exist so the label leads with the most serious hazard rather than burying it under redundant lower-tier symbols. You don't have to memorize them — but knowing they exist explains why a chemical you know is an irritant might not show the exclamation mark: a more severe pictogram outranked it.

Supplemental Information Is Allowed — With a Catch

Manufacturers can add supplemental information to a label — batch numbers, fill dates, HMIS or NFPA rating blocks, extra handling notes. This is permitted, but Appendix C.3.1 draws the line: supplementary information "is limited to when it provides further detail and does not contradict or cast doubt on the validity of the standardized hazard information." An HMIS color bar, for instance, is supplemental — it does not replace the required pictograms, signal word, and hazard statements. If supplemental content makes the required elements harder to find or seems to soften them, that's a labeling problem.

What Changed Under HazCom 2024 — and the November 2026 Deadline

OSHA's 2024 update to the Hazard Communication Standard (aligning it with GHS Revision 7) kept the six required label elements intact but refined several labeling provisions. Three are worth knowing:

• Small-container labeling — the (f)(12) tiers described above are new in the 2024 rule.
• "Released for shipment." The rule now defines a chemical as released for shipment once it "has been packaged and labeled in the manner in which it will be distributed or sold," and (f)(11)(i) gives manufacturers, importers, distributors, and employers "the option not to relabel" containers that have been released for shipment and are awaiting future distribution when new hazard information surfaces. New information still has to reach labels on containers shipped after the six-month revision window — it just doesn't force a warehouse full of packaged product to be re-labeled.
• Label updates on new information — (f)(11)(i) keeps the long-standing duty to revise labels "within six months of becoming aware of the new information."

The compliance dates were extended in January 2026. The date that matters most for a typical small business is the employer deadline of November 20, 2026 for substances — by then your workplace labeling, written program, and training need to reflect the updated standard. The November 2026 HazCom deadline guide breaks down exactly what employers have to do and by when. One practical note: the manufacturer deadline for substances passed on May 19, 2026, so updated labels and SDSs for the chemicals you already buy exist now — if a supplier is still shipping you the old ones, ask.

How to Check the Labels Arriving at Your Business

You don't need to be a chemist to audit incoming labels. Walk through this quick sequence when a new chemical arrives:

1. Is there a full label at all? Every shipped hazardous chemical should arrive with a complete GHS label. A container with only a manufacturer's brand label and no hazard information is a red flag.
2. Does the product identifier match the SDS? Pull the Safety Data Sheet and confirm the name or number on the label matches Section 1 of the SDS. A mismatch breaks the link workers rely on.
3. Are all six elements present? Product identifier, signal word (if assigned), hazard statement(s), pictogram(s), precautionary statement(s), supplier name / U.S. address / U.S. phone.
4. Are the pictograms formatted correctly? Red diamond frame, black symbol, white background. No black frames, no empty diamonds.
5. If it's a small container, is the outer package labeled and kept? Under (f)(12) the carton carries the full label — it stays with the product.
6. Is the SDS on file? A compliant label is only half the system. If you can't produce the matching SDS, you have a HazCom gap regardless of how good the label looks.

If a label fails any of these checks, document it, keep using appropriate PPE in the meantime, and contact the supplier for corrected labeling. A manufacturer that shipped you a non-compliant label has a legal obligation to fix it. The HazCom self-audit checklist folds this receiving check into a whole-facility walk-through.

Where the Penalties Land

Labeling violations fall under the Hazard Communication Standard, which is consistently among OSHA's most-cited standards year after year. As of 2026, a serious violation carries a maximum penalty of $16,550 per violation, and willful or repeated violations can reach $165,514 (osha.gov/penalties, amounts effective after January 15, 2026). Because each improperly labeled container can be cited separately, a single walk-through that turns up a dozen problem containers can compound quickly.

The subtler risk is that labeling failures rarely travel alone. An inspector who finds a missing or non-compliant label will almost always check whether you have the matching SDS, whether your written program addresses labeling, and whether your employees were trained to read the labels. One bad label becomes a thread the inspector pulls on.

Keeping Labels and SDSs in Sync

The recurring theme in every one of these requirements is the link between the label and the Safety Data Sheet — the product identifier that has to match, the hazards that have to be consistent, the supplier you have to be able to reach. A label without its SDS, or an SDS with no way to find the product on the floor, defeats the whole purpose of the system.

This is exactly the gap SafeSheet is built to close. Every chemical in your inventory carries its SDS, its GHS classification, and a per-location QR code, so a worker who scans the code on a container pulls up the full hazard information in seconds — and when you need a compliant secondary-container label, SafeSheet generates it directly from the classification data you've already entered, with the correct pictograms, the stored signal word, and a matching product identifier. Expiration alerts keep the underlying SDSs current so your labels never reference stale hazard data. The result is a labeling system where the container, the label, and the data sheet always point at the same thing.

GHS Label Questions, Answered in One Line

How many elements are required on a GHS label? Six — product identifier, signal word, hazard statement(s), pictogram(s), precautionary statement(s), and supplier name / U.S. address / U.S. phone (1910.1200(f)(1)).

Which element is not required on a GHS label? Anything outside those six — expiration dates, NFPA/HMIS ratings, CAS numbers, lot numbers, and the environmental pictogram are all optional or supplemental.

Do workplace (secondary) labels need all six? No. Under (f)(6) they need either the first five elements, or the product identifier plus general hazard information backed by your written program and SDS access.

Does OSHA require the environmental pictogram? No — eight of the nine GHS pictograms are required; environmental hazards aren't in OSHA's jurisdiction.

Can pictogram borders be black? No. Red frames are required on shipped labels, domestic or international. An unused preprinted diamond may be fully blacked out; an empty red frame is not permitted.

Is there a minimum GHS label size? No numeric minimum. Labels must be prominently displayed and legible; containers of 100 mL or less may use the reduced (f)(12) label with the full label on the outer package.

Who is responsible for a non-compliant shipped label? The manufacturer, importer, or distributor who shipped it must fix it — but you must keep it intact and legible, and you can't put an unlabeled container into service.

The Bottom Line

A compliant shipped GHS label is not complicated once you know what to look for: product identifier, signal word, hazard statement(s), pictogram(s), precautionary statement(s), and supplier information — six elements, defined by the chemical's classification, tied to a matching SDS. Everything else on the label is supplemental. Manufacturers are responsible for getting the label right before it ships. You're responsible for keeping it legible, making sure your incoming chemicals actually carry it, and reproducing the essential information whenever you transfer a chemical into a container of your own.

Learn to run the six-element check in thirty seconds, build it into receiving, and you've closed one of the most commonly cited gaps in the entire standard — long before the November 20, 2026 employer deadline makes it urgent.
