The classification of goods and services shall conform to the classifications adopted by the United States Patent and Trademark Office. A single application for registration of a mark may include any or all goods upon which, or services with which, the mark is actually being used indicating the appropriate class or classes of goods or services. When a single application includes goods or services that fall within multiple classes, the secretary may require payment of a fee for each class.

Section § 14235
This law states that when registering a trademark, you need to use the same categories for goods and services that the U.S. Patent and Trademark Office uses. You can register a mark for multiple products or services in one application, but if they belong to different categories, you might have to pay a fee for each category.
