Let's break it down.
What is an SDS (Safety Data Sheet)?
A Safety Data Sheet is a regulatory document required by law under OSHA's Hazard Communication Standard (HazCom 2012) and aligned with the Globally Harmonized System (GHS). It communicates the hazards of a chemical product and provides critical safety information to anyone who handles, stores, transports, or is exposed to it.
What an SDS contains (16 standardized sections)
- •Hazard identification
- •Composition / ingredients
- •First-aid measures
- •Firefighting measures
- •Accidental release measures
- •Handling and storage
- •Exposure controls / personal protection
- •Toxicological information
- •Regulatory information
- •Transport information
Bottom line: The SDS is about safety and compliance. It's legally required for hazardous chemicals and must be accessible to employees.
What is a TDS (Technical Data Sheet)?
A Technical Data Sheet is a product performance document. It's created by the manufacturer to communicate the technical specifications of a product think of it as the product's r e9sum e9.
What a TDS typically includes
- •Physical properties (viscosity, density, pH, color)
- •Application instructions
- •Recommended usage and dosage
- •Performance data (cure time, tensile strength, shelf life)
- •Storage and handling recommendations (performance-focused)
Bottom line: The TDS is about how the product works. It's a technical + sales tool not a regulatory requirement.
Key differences at a glance
| Feature | SDS | TDS |
|---|---|---|
| Purpose | Safety & hazard communication | Product performance & specs |
| Required by law? | Yes (OSHA/GHS) | No |
| Audience | Workers, safety teams, regulators | Formulators, engineers, buyers |
| Format | Standardized (16 sections) | Varies |
| Covers hazards? | Yes detailed | Minimal |
| Covers performance? | Minimal | Yes detailed |
Why the confusion matters
Here's where it gets real: using a TDS in place of an SDS can put your business at serious legal and safety risk.
Regulatory audits
OSHA inspectors look for SDS documents not TDS. If you can't produce them, you're looking at citations and fines.
Workplace safety
Employees need to know what PPE to wear, what to do in a spill, and how to handle exposure. That information lives on the SDS, not the TDS.
Product liability
If an incident occurs and you only have a TDS on file, you may face liability for inadequate hazard communication.
On the flip side, relying solely on an SDS when you need technical performance data can lead to formulation errors, misapplication, and wasted product.
Do you need both?
Usually, yes. If you manufacture, distribute, or use chemical products:
SDS
Keeps you compliant and your people safe.
TDS
Helps your team (and your customers) use the product correctly.
