A major class in trademark registration usually contains multiple subclasses. A major class is a broad classification of goods and services, while a subclass is more specific, breaking down various different types of goods or services.

Although the major categories cover a relatively broad range, not all subcategories are included. Each subclass describes a related group of goods or services to more accurately define the scope of use of the trademark.

When applying for trademark registration, the applicant needs to select one or more subcategories related to its goods or services to ensure that the trademark is protected within the appropriate scope.
