If you've worked around hazardous chemicals for any length of time, you've likely come across MSDS labels on containers, storage cabinets, or binder spines in the back office. These labels were once the backbone of chemical hazard communication in workplaces across the United States, helping employees quickly identify what they were handling and what risks came with it.
But here's where things get confusing. OSHA officially transitioned from the MSDS format to the globally harmonized SDS system back in 2012, and full compliance has been required since 2016. So why are people still searching for MSDS labels? Because plenty of workplaces still have legacy chemicals, older inventory, or internal systems that reference the old format. And some facilities simply need clarity on what's still required versus what's been replaced.
This article breaks down what MSDS labels are, how they differ from current SDS and GHS labels, and when you might still need them. At Safety Decals, we've spent years helping businesses across manufacturing, construction, and transportation get their safety labeling right, whether that means custom hazard labels, regulatory-compliant decals, or guidance on which standards actually apply to your operation.
Why MSDS labels still show up in 2026
Despite the regulatory shift that happened over a decade ago, MSDS labels continue to appear in workplaces across the country. The reason isn't that companies are ignoring the rules. It's that hazardous chemicals have long shelf lives, and products purchased before the 2016 compliance deadline often carry original labeling that hasn't been replaced, relabeled, or even reviewed since they arrived on site.
If you find legacy MSDS documentation in your facility, pull the current SDS from the manufacturer to confirm the hazard information is still accurate and complete.
Legacy inventory and long shelf-life chemicals
Some chemicals, including industrial solvents, lubricants, and specialty coatings, can sit in storage for years before anyone uses them. Drums, tanks, and containers purchased before 2016 may still carry MSDS-formatted labeling from the original manufacturer. Finding these products in your facility isn't automatically a compliance violation, but it does require your attention before someone on your team picks up that container.
Reviewing legacy inventory and comparing old labels against current SDS documents is the right move. Many safety managers work through this during annual audits rather than replacing everything at once, which is a practical approach for large facilities with substantial stock on hand.
International suppliers and imported products
Not every country adopted the GHS framework on the same timeline. Suppliers operating outside the United States may still ship products with documentation that references the legacy MSDS format rather than the current SDS standard. Your receiving team might accept imported chemicals, components, or materials that carry labels not aligned with what OSHA now requires for domestic workplaces.
Requesting updated SDS documentation from foreign suppliers is a straightforward and necessary step when this happens. If the supplier cannot provide current documentation, you may need to create a compliant secondary label before the product enters your workflow.
MSDS vs SDS and GHS labels: what changed
The move from MSDS to SDS wasn't simply a name change. OSHA aligned with the Globally Harmonized System of Classification and Labelling of Chemicals, known as GHS, to create a consistent standard for how workplaces communicate chemical hazards across industries and borders.
What GHS standardized on labels
Before GHS, hazard labels varied significantly between manufacturers. GHS labels now require six specific elements: a signal word, hazard statements, precautionary statements, pictograms, the product identifier, and supplier contact information. This structure lets workers read and interpret labels quickly, regardless of who produced the chemical.
If a label on your container is missing any of these six elements, it does not meet current OSHA HazCom 2012 requirements.
What stayed the same
The core goal behind MSDS labels and their current SDS replacements is identical: give workers accurate hazard information before they handle a chemical. The underlying safety data didn't change. What changed was the format, the organization, and the visual consistency that GHS introduced.
Your team's existing knowledge of chemical hazards carries over directly. Reading an SDS is straightforward once you understand the standardized 16-section format that replaced the variable structure of the old MSDS.
When you still need MSDS labels at work
Even with OSHA's full compliance deadline years behind us, there are real situations where MSDS labels remain relevant to your daily operations. Understanding when they still apply helps you avoid gaps in your hazard communication program rather than assuming everything has been automatically updated across your entire facility.
During chemical inventory reviews
When you conduct a thorough audit of your storage areas, you may find containers with MSDS labels that predate the GHS transition. Your obligation is to verify that the hazard information on those old labels still accurately reflects the chemical's current classification. If the SDS from the manufacturer confirms the hazard data matches, you can treat the product as compliant while you work through relabeling at a practical pace.
Prioritize relabeling any MSDS-labeled containers that workers handle daily before addressing slower-moving inventory in storage.
When onboarding new employees
New hires may encounter legacy-labeled containers before you've completed a full relabeling cycle. Your training program should cover both formats so workers understand what MSDS documentation communicates and how it relates to the current SDS standard. Covering both formats prevents confusion on the floor and removes the need to halt operations for an immediate full-scale replacement.
What an MSDS or SDS label must include
Whether you're reviewing current SDS-formatted containers or working through older MSDS labels still in circulation, knowing what a compliant label must contain keeps your team protected and your facility aligned with OSHA requirements. HazCom 2012, aligned with GHS, defines exactly what needs to appear on every hazardous chemical container.
The six required GHS label elements
Current SDS labels must carry six specific elements to meet OSHA's requirements. Each element serves a distinct purpose in communicating hazard information quickly and consistently across your workforce.
- Product identifier: the name or code matching the SDS
- Signal word: either "Danger" or "Warning" based on severity
- Hazard statements: describe the nature of the hazard
- Precautionary statements: cover handling, storage, and emergency response
- GHS pictograms: standardized symbols indicating hazard type
- Supplier information: name, address, and phone number
A label missing any of these six elements does not comply with OSHA HazCom 2012, regardless of how thorough the rest of the label appears.
What older MSDS labels covered
Older MSDS labels carried much of the same core hazard information but in a far less standardized format. Manufacturers organized data differently, which made quick interpretation harder for workers unfamiliar with a specific product's layout.
Comparing an old MSDS label against the current SDS for the same product confirms whether the hazard information still accurately reflects the chemical's classification before workers handle it.
How to choose and apply compliant labels
Replacing outdated MSDS labels or adding new compliant labels to your chemical containers requires two decisions: the right material and the right application method. Getting both right determines whether your labels stay readable through the full life of the chemical in your facility.
Selecting the right label material
Label durability depends heavily on where the container lives and what it contacts. A label inside a climate-controlled storage room faces far less stress than one on a drum sitting in an outdoor yard or near a wash-down area. Match your material to your environment before ordering.
For containers exposed to chemicals, solvents, or moisture, choose a polyester or vinyl label stock rather than standard paper, which deteriorates quickly and creates a compliance gap.
Applying labels correctly
Clean and dry the container surface before applying any label. Grease, dust, or moisture underneath a label causes edges to peel, which can obscure critical hazard information within weeks of application.
Position your new GHS-compliant label so it faces outward and remains fully visible when the container is in its normal storage position. Covering any of the six required elements with tape, secondary packaging, or another label creates the same compliance problem as leaving the element off entirely.
Next steps
Now that you understand where msds labels fit within the current regulatory landscape, the practical move is to walk your facility and identify what's still out there. Check your storage areas, production floors, and receiving docks for any containers carrying the old format, then cross-reference the hazard information against the current SDS from each manufacturer.
Replacing outdated labels with GHS-compliant versions protects your workers and keeps your facility in line with OSHA HazCom 2012. Material selection matters, so match your label stock to the conditions the container actually faces, whether that's chemical exposure, moisture, or outdoor storage.
Getting the labels right is not complicated when you work with people who understand the standards. Safety Decals has helped businesses across manufacturing, transportation, and construction get their chemical labeling in order using durable, accurate materials built for real workplace conditions. Request custom safety labels for your facility and get labeling that holds up where it matters.
