When you think about trademarks, chemicals might not be the first thing that comes to mind. Yet for many businesses, protecting their chemical products is critical to safeguarding their brand and reputation. If your company manufactures or sells chemicals for industrial, agricultural, or scientific purposes, you’ll need to understand International Trademark Class 1. Registering your mark under the correct class is essential for securing broad protection—and avoiding costly disputes down the line.
Let’s walk through exactly what Class 1 covers, explore real-world examples, and discuss practical tips for businesses considering registration.
What Is International Trademark Class 1?
International Trademark Class 1 is part of the Nice Classification system, which standardizes how goods and services are categorized for trademark purposes worldwide.
Class 1 includes:
- Chemicals used in industry, science, and photography
- Chemicals used in agriculture, horticulture, and forestry
- Unprocessed plastics
- Fertilizers
- Fire extinguishing compositions
- Tempering and soldering preparations
- Chemical substances for preserving foodstuffs
- Tanning substances
- Industrial adhesives
In essence, if you sell raw chemical compounds intended for industrial or commercial use—not finished consumer goods—your products likely belong in Class 1.
Examples of Products in Class 1
- Industrial adhesives for construction and manufacturing
- Agricultural fertilizers
- Fire-retardant chemical sprays
- Photographic developing chemicals
- Unprocessed synthetic resins for plastics manufacturing
- Water treatment chemicals for industrial facilities
It’s important to note: if a chemical is packaged and sold directly to consumers (such as a cleaning spray), it may fall under a different class, like Class 3.
Why Proper Classification Matters for Chemical Businesses
Choosing the right class isn’t just a formality—it can be the difference between a strong trademark and one that’s difficult (or impossible) to enforce.
Chemical businesses face particular risks because their goods can overlap with multiple classes. Filing mistakes can:
- Result in USPTO Office Actions that delay registration.
- Leave brands vulnerable to infringement from improperly categorized competitors.
- Limit the scope of enforceable trademark rights.
Real-world example: Eastman Chemical Company v. Eastman Outdoors, Inc. saw a global chemical manufacturer oppose a consumer cooking products brand. Although Eastman Chemical registered primarily in Class 1, they struggled to enforce against consumer goods outside their chemical portfolio. Proper, strategic filing across classes could have strengthened their position.

Real-World Examples: Class 1 in Action
Several major companies rely on Class 1 registrations to protect their chemical brands:
- BASF SE: Covers a wide array of industrial chemicals and unprocessed plastics.
- Dow Chemical Company: Protects adhesives, agricultural chemicals, and raw resins.
- 3M Company: Separates industrial adhesives (Class 1) from consumer products like tapes (Class 16) and cleaners (Class 3).
- DuPont: Owns Class 1 trademarks for materials like TYVEK®, used in construction and industrial applications.
Meanwhile, even global brands make mistakes: Nestlé sought to register “milk proteins” in Class 1. The USPTO and TTAB ruled that because the proteins were food ingredients, they belonged in Class 29, not Class 1. Misclassification delayed Nestlé’s registration.
How to Draft Goods Descriptions Properly
Getting your goods description right can make or break your application.
USPTO trends show that applications using vague descriptions like “chemicals for industrial purposes” often receive Office Actions demanding clarification. Instead, applicants should:
- Specify the industry: “chemicals for use in the construction industry”
- Specify the application: “adhesives for use in automobile manufacturing”
- Specify the form: “unprocessed synthetic resins in pellet form”
Precise descriptions not only speed up examination but also strengthen your mark’s enforceability.
When Filing in Multiple Classes Is Necessary
Your chemical product might fit into more than just Class 1.
For example:
- An industrial adhesive (Class 1) packaged for retail as a consumer glue (Class 16)
- A raw disinfecting chemical (Class 1) marketed as a household cleaner (Class 3)
- An agricultural chemical that doubles as a veterinary treatment (requiring Class 5)
Filing in multiple classes ensures broader protection across all of your product’s potential uses. Learn more about trademark clearance and multi-class filing.
Conclusion: Protect Your Chemical Brand with Confidence
International Trademark Class 1 may seem specialized, but it’s critical for businesses operating in chemical, agricultural, and scientific industries. Getting your trademark filing right—with a clear understanding of your goods, careful drafting, and strategic multi-class planning—can be the foundation of your brand’s success.
Key takeaways:
- Class 1 covers chemicals used in industry, agriculture, and science.
- Precision matters: Avoid vague goods descriptions.
- Filing across multiple classes may be necessary to fully protect your brand.
