Trademark Class 21: Housewares and kitchen — What It Covers, With a Live Count
Short answer
Trademark class 21 covers household and kitchen utensils and containers, cookware, glassware, porcelain, brushes, cleaning tools, and small non-electric appliances. It is a goods class, and as of September 14, 2026 it holds 171,893 live US marks, 3.6% of the register, ranking 8 of 45 by size. A registration in class 21 protects the name only for these goods; the same name can be, and often is, registered by an unrelated business in another class.
Class 21 is a large class, with 171,893 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 21 is the non-electric kitchen and the tools for cleaning a house. A blender is 7; a whisk is 21; a knife is 8; a cutting board is 21. Water bottles and insulated tumblers are the crowded corner of the class. Electric toothbrushes stay in 21 by convention, like electric razors in 8.
What files in class 21
| Typically in class 21 | Examples of businesses |
|---|---|
| cookware: pots, pans, bakeware | kitchenware brands |
| kitchen utensils and gadgets | drinkware companies |
| drinkware, mugs, and water bottles | home goods labels |
| dinnerware and glassware | cleaning tool makers |
| food storage containers | oral care brands (brushes) |
| cleaning tools: brushes, mops, sponges | |
| toothbrushes and combs | |
| plant pots and vases | |
| coolers and lunch boxes |
The USPTO's ID Manual lists the accepted descriptions for class 21. 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 21
| Looks like class 21, but is | Class |
|---|---|
| electric kitchen appliances | 7 |
| cutlery and knives | 8 |
| electric toothbrushes | 21 |
| cleaning chemicals | 3 |
| cooking, heating appliances | 11 |
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 21; the second class is a second filing fee, and a registration in one does not cover the other.
Coordinated classes
The USPTO searches class 21 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 21 application, and a class 21 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 21 is
| Live marks in class 21 | 171,893 |
| Share of the 45-class register | 3.6% |
| Rank by size | 8 of 45 |
| As of | September 14, 2026 |
A crowded class means more near matches to read through, and a higher chance that one of them is in your actual field. With this many live marks, a coined name of five or six letters will almost always have a neighbour somewhere in the class; the question is whether the goods overlap.
Before you file in class 21
- Confirm the goods are actually class 21 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 21 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.
