Trademark Class 1: Chemicals — What It Covers, With a Live Count
Short answer
Trademark class 1 covers industrial chemicals, unprocessed plastics and resins, fertilizers, adhesives for industry, and chemicals used in science, photography, agriculture, and manufacturing. It is a goods class, and as of September 14, 2026 it holds 83,557 live US marks, 1.7% of the register, ranking 19 of 45 by size. A registration in class 1 protects the name only for these goods; the same name can be, and often is, registered by an unrelated business in another class.
Class 1 is a mid-sized class, with 83,557 live marks out of 4,796,936 across all 45 classes. A live mark is one that is registered or pending; the count is computed from USPTO bulk data by each mark's primary class and refreshed daily.
Class 1 is the raw-material class: the chemical before it becomes a product. The moment a chemical is packaged for a consumer use it usually moves — cleaning products to 3, supplements to 5, fuel to 4. A fertilizer sold to farmers stays in 1; a lawn treatment sold to homeowners is often still 1, but a weed killer is 5.
What files in class 1
| Typically in class 1 | Examples of businesses |
|---|---|
| industrial chemicals | chemical manufacturers |
| fertilizers and soil amendments | agricultural input suppliers |
| unprocessed artificial resins and plastics | biotech reagent companies |
| adhesives for industrial use | industrial adhesive makers |
| chemicals for photography and film processing | |
| water treatment chemicals | |
| laboratory reagents |
The USPTO's ID Manual lists the accepted descriptions for class 1. Choosing one of them keeps the filing fee at $350 per class; a custom description costs $550. See what a trademark costs.
What is not in class 1
| Looks like class 1, but is | Class |
|---|---|
| household cleaning products | 3 |
| pharmaceuticals and supplements | 5 |
| paints and varnishes | 2 |
| fuels and lubricants | 4 |
| finished plastic goods | 17 |
The class follows the product, not the industry. A business in this field will often need one of the classes above as well as class 1; the second class is a second filing fee, and a registration in one does not cover the other.
Coordinated classes
The USPTO searches class 1 together with these classes when it examines an application, because confusion between them is common. A live mark in a coordinated class can block a class 1 application, and a class 1 mark can block one of these.
A near match in a coordinated class is worth reading closely. A near match anywhere else on the register is usually not. See is my name trademarked for how to read one.
How crowded class 1 is
| Live marks in class 1 | 83,557 |
| Share of the 45-class register | 1.7% |
| Rank by size | 19 of 45 |
| As of | September 14, 2026 |
A smaller class means fewer near matches, and a name that is clear here tends to stay clear. It is still worth searching the coordinated classes, since that is where a conflict for a class 1 mark most often comes from.
Before you file in class 1
- Confirm the goods are actually class 1 against the USPTO ID Manual, not against the industry the business is in.
- Check the neighbouring classes in the table above for anything the business also sells or does.
- Search the name on Silvol and read every live match by class: class 1 and its coordinated classes matter; others usually do not.
- Budget per class. Each class is $350 to file and $650 every ten years to maintain.
