N.J. Stat. Ann. § 56:3-13.9a

12. The secretary shall by regulation establish a classification of goods and services for convenience of administration of this act, but which shall not limit or extend the applicant's or registrant's rights, and a single application for registration of a mark may include any or all goods or services on or in connection 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 which fall within multiple classes, the secretary shall require payment of a fee for each class. The classification of goods and services shall conform to the classification adopted by the United States Patent and Trademark Office pursuant to 15 U.S.C. s.1112.
