Trademark Class 21: Housewares and glass
Household and kitchen utensils, cookware, glassware, porcelain and earthenware.
What class 21 covers
Class 21 is one of the 45 international classes used by the USPTO and most trademark offices worldwide, under the Nice Classification. Classes 1 to 34 cover goods — physical products — and classes 35 to 45 cover services. Class 21 is a goods class.
You register a mark for particular goods or services, not in the abstract. That is why the same word can be owned by unrelated businesses in different classes, and why picking the right class matters as much as picking the right name.

Choosing the right class
Three mistakes cost applicants the most in this area:
- Filing in too few classes. If you sell a product and also provide a service around it, that is often two classes. Registering only one leaves the other unprotected.
- Filing in too many. Each class costs a separate fee, and the USPTO expects you to be using the mark, or to have a genuine intent to use it, for everything you list.
- Ignoring related classes. Examiners routinely treat certain classes as related — clothing and clothing retail, for instance, or food products and restaurant services. A conflict in a related class can block you just as effectively as one in your own.
Our search checks related classes automatically, so a conflict in an adjacent class shows up rather than being silently ignored.
