A trademark classification is a way the trademark examiners and applicants' trademark attorneys arrange documents, such as trademark and service mark applications, according to the description and scope of the types of goods or services to which the marks apply. The same trademark or service may be (or in many cases MUST be) classified in several classes, and some countries permit several classes to be registered in the same document. There are fees ordinarily associated with each classification, whether for initial application or later renewal.
