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 the regulation.
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 not always, and 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 the six required elements of a manufacturer's GHS label, where each one comes from, how the rules differ for the labels you make in-house, and how to spot a non-compliant label before it costs you.
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 OSHA's 29 CFR 1910.1200(f)(1) governs, and it's what 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 more flexibility here. Under 1910.1200(f)(6), your in-house label needs only the product identifier plus words, pictures, or symbols that convey the general hazards — or you can simply reproduce the full shipped-container label. The reduced requirement is why the secondary container labeling rules look so different from the six elements below.
This post is about the full label — the one your suppliers are legally required to get right, and the one you're required to keep intact.
You are not allowed to remove or deface the manufacturer's label on an incoming container. 1910.1200(f)(4) requires employers to keep shipped-container labels legible and in place. If a label gets damaged or falls off, you have to replace it with one carrying the same information — you can't just toss the container into service unlabeled.
The Six Required Label Elements
Here are the six elements every shipped GHS label must carry, in the order the standard lists them.
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 — the label shows "Danger," not both. If a product's hazards are all mild enough that no signal word is assigned, the label simply has none.
3. Hazard Statement(s)
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, 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 statements must appear on the label — a manufacturer can't cherry-pick the ones that sound less alarming.
4. Pictogram(s)
Pictograms are the red-bordered diamond symbols that communicate hazard type without words. OSHA designates eight mandatory pictograms for workplace labels in the United States: health hazard, flame, exclamation mark, gas cylinder, corrosion, exploding bomb, flame over circle, and skull and crossbones. A ninth GHS pictogram — the environment symbol (dead tree and fish) — is part of the international system but is not required by OSHA, because environmental hazards fall under EPA jurisdiction rather than OSHA's.
Each pictogram appears only once per label, no matter how many hazard classes it covers, and each is a black symbol on a white background inside a red diamond frame. A blank red diamond with no symbol is not permitted — every pictogram on a label must correspond to an actual hazard. For a plain-English walkthrough of what each symbol means and what to do when you see it, see GHS pictograms explained.
The red border must be red — not black. Manufacturers occasionally ship labels with black-bordered diamonds to cut printing costs, and OSHA has explicitly stated that a black border does not comply. If you receive containers with black-bordered pictograms, that's a non-compliant label; document it and request corrected labeling from your supplier.
5. Precautionary Statement(s)
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 largely standardized based on classification. A fully loaded label can carry a long list of precautionary statements, and manufacturers are given some latitude to consolidate or prioritize them when a label would otherwise be overwhelmed — 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. 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.
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. OSHA's Appendix C to 1910.1200 ("Allocation of Label Elements") lays out precedence rules so that a multi-hazard label stays readable instead of contradicting itself:
- Signal word: if "Danger" applies to any hazard, only "Danger" appears — "Warning" is dropped.
- Skull and crossbones vs. exclamation mark: if the skull and crossbones applies, the exclamation mark is not shown for acute toxicity.
- Corrosion vs. exclamation mark: if the corrosion pictogram applies for skin or eye damage, the exclamation mark is not shown for skin or eye irritation.
- Health hazard vs. exclamation mark: if the health hazard pictogram applies for respiratory sensitization, the exclamation mark is not shown for that same effect.
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 OSHA draws a line: supplemental information can't contradict or cast doubt on the required GHS elements, and it can't be used to satisfy a required element. 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. Two are worth knowing:
- "Released for shipment" labeling. Manufacturers no longer have to re-label a container already packaged and awaiting shipment every time new hazard information surfaces — instead, new containers must reflect the updated information going forward, with the date-released tracked. This reduces churn but doesn't change what a compliant label contains.
- Small container relief. For containers too small to hold a full label (think 100 mL or less), the updated rule provides specific alternatives, such as pull-out or fold-back labels and reduced information on the immediate container with full information on the outer package.
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.
You are not responsible for authoring shipped-container labels — that's the manufacturer's job. But you are responsible for making sure incoming chemicals arrive properly labeled and stay that way in your facility. Build a 30-second label check into your receiving process: product identifier matches the SDS, pictograms have red borders, signal word and hazard statements are present. Catching a bad label at the dock is far cheaper than explaining it to an inspector.
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:
- 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.
- 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.
- 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.
- Are the pictograms formatted correctly? Red diamond border, black symbol, white background. No black borders, no blank diamonds.
- 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.
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. 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 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.
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. 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.
