How Many Trademark Classes Do You Need, and What If You Pick the Wrong Ones?

Our main copyright and trademark law page explains what a federal registration protects; this page is about drawing its edges. Two parts of the application do that work. The class number is the USPTO's filing category, and it sets the fee. The identification, the plain-English list of goods and services, is what your rights actually cover. Get the classes wrong and you pay for the wrong things. Get the identification wrong and you can end up with a registration that misses the product you care about, or one that lists products you will later have to defend or delete.

How to Choose Your Classes, Step by Step

1. List what the mark is on. Every product and service you sell under it now, and those you genuinely plan to offer.
2. Find each item in the ID Manual. The USPTO's Trademark ID Manual gives pre-approved wording and the class for each entry.
3. Group items by class. Each different class number is one class fee (37 CFR 2.86(a)(2)).
4. Cut anything speculative. Each item needs current use or a bona fide intent to use; the USPTO says you must have one or the other for all the goods and services you list.
5. Decide on one application or several. One multiple-class application gets one certificate (37 CFR 2.86(f)); separate applications let each class move on its own schedule.
6. Budget per class. Filing, any statement of use and extensions, and every maintenance filing are charged per class.

What Is the Difference Between a Class and the Identification?

There are 45 international classes, 34 for goods and 11 for services, set out in 37 CFR 6.1. The USPTO describes them as a way to organize applications, assess fees and aid in searching, and notes that goods and services are never in the same class. Class 25, for example, is "Clothing, footwear, headwear," and Class 41 is "Education; providing of training; entertainment; sporting and cultural activities."

The identification is what defines your rights. The examination manual explains that because the filing date becomes nationwide constructive use once the mark registers, the identification "defines the scope of those rights" (TMEP 1402.06). To decide what an identification covers, the USPTO reads the ordinary meaning of the words apart from the class number, and the class number does not limit the scope of permissible amendments (TMEP 1402.07(a)). And copying a class heading does not claim everything in the class. The manual says the headings use wording that is "indefinite and/or too broad" to identify particular goods (TMEP 1401.08), so a bare heading such as "clothing" can draw a requirement to name the actual items.

Classes also do not decide who conflicts with whom. The USPTO says related goods "don't have to be in the same international class." Our page on checking whether a trademark is available explains why a search should cover coordinated classes too.

What Does Each Class Cost?

The base application fee is $350 per class, and a multiple-class application must pay it for each class (37 CFR 2.86(a)(2)). The USPTO's own example: golf shirts, dress shirts and T-shirts all fall in one class, so the fee is $350; add custom T-shirt printing services and you have goods and services in two classes, $700. Writing your own description instead of choosing ID Manual entries adds $200 per class, and each extra 1,000 characters of free-form text adds $200 per affected class.

The per-class math repeats later. An intent-to-use applicant pays $150 per class for the statement of use and $125 per class for each extension, and the Section 8 declaration and the ten-year renewal are also charged per class. Our page on what a federal trademark costs, from filing to renewal totals those fees over ten years.

Which Classes Do Creators and Small Brands Usually Need?

Start with what earns the money. For a performer, that is usually entertainment services in Class 41. Recorded music sold or distributed as downloads is a product, and the ID Manual places "Downloadable music files" and "Musical sound recordings" in Class 9. Merchandise is where classes multiply: shirts and hoodies are Class 25, mugs Class 21, stickers Class 16, and tote bags Class 18. Our page on trademarking a band or artist name covers the extra hurdles for performers' names. For channel and brand names, see our guide to trademark protection for content creators and influencers.

Merchandise also raises a question classes cannot answer. A name printed large across the front of a shirt can be refused as ornamental rather than a source indicator, whatever the class. Our page on trademark classes for merchandise explains that refusal and how licensing fits in.

Classes also change. The 13th edition of the international classification took effect January 1, 2026, and among other changes moved sunglasses, eyeglasses and contact lenses from Class 9 to Class 10 (TMEP 1401.16(a)); the ID Manual now lists the old Class 9 "Sunglasses" entry as deleted. A further rule effective January 1, 2027 changes only wording in the Class 6 and Class 9 headings. Check the ID Manual on the day you file.

What Goes Wrong If You List Too Much?

Every item needs a real basis. The USPTO's applicant guide says that for use-based items you must be using the mark on all of them, and for intent-to-use items you must have a good faith intent to use it on all of them. Padding the list has several costs:

• Fees for classes you never use. Each class is $350 at filing and repeats at each maintenance filing.
• A stalled statement of use. You cannot file one until the mark is in use on everything for which you seek registration in that application, unless you delete the rest or divide them out (37 CFR 2.88(a)(2)).
• Specimens for each class. Every class claimed on use needs its own specimen (37 CFR 2.86(a)(3)); our page on what to do when a specimen is refused covers that step.
• Audits after registration. The USPTO randomly audits registrations with one class of four or more items, or two classes with two or more items each, and asks for proof of use on more items. Deleting goods during the audit costs $250 for each class with deletions.
• Challenges for nonuse. A third party can petition to expunge goods or services on which a registered mark was never used, at $400 per class, and the USPTO will delete them if the petition succeeds. Our page on losing a trademark through nonuse covers the wider risk.

What If You Left Something Out or Picked the Wrong Class?

It depends on which mistake. If you listed the right item but under the wrong class number, the fix is usually simple. The examiner must require either payment for the extra class or an amendment limiting the application to the classes already paid for (TMEP 1401.04(b)), and because the class number does not limit the identification, the item can move to its proper class.

If you left the item out entirely, you cannot add it. Under 37 CFR 2.71(a), an applicant may amend the identification "to clarify or limit, but not to broaden" it. An item you expressly delete cannot be put back in a later amendment (TMEP 1402.06(a)). The answer is a new application for the missing goods, with its own fee and its own, later filing date, which matters if someone else files in between.

When Does Dividing an Application Help?

A request to divide splits one application into two or more, so classes ready to register are not held back by classes that are not (37 CFR 2.87). The fee is $100 for each new application created when you divide out entire classes; splitting some goods out of a class also requires a new application filing fee for each new application. You can divide any time before approval for publication, with a statement of use, or, in an application with mixed filing bases, between the notice of allowance and the statement of use. The USPTO's wait times page lists an average of 138 days to process a division, so build that into any launch plan.

What Changes the Answer

• Your filing basis per class. Use-based classes need dates and a specimen now; intent-to-use classes need a bona fide intent (37 CFR 2.86(a)(3)). Our page on filing as in use or intent to use explains the choice.
• A Madrid filing. In a Section 66(a) application, the classification cannot be changed and classes cannot be added (TMEP 1401.04).
• Classification updates. New editions of the international classification apply to applications filed on or after their effective date (TMEP 1401.16).
• Licensing plans. A licensee selling goods in a class you did not claim leaves those goods unregistered.
• Budget. Every class multiplies the ten-year government cost, so a class you will not use for years may be better filed later.

A Worked Example

Common Mistakes

• Copying the class heading. Headings are too broad to identify goods and do not cover the whole class (TMEP 1401.08).
• Filing in every class "just in case." Each needs a real basis, and unused items invite audits and expungement.
• Leaving out a core product to save a fee. You cannot add it later (37 CFR 2.71(a)).
• Using free-form wording without need. It costs $200 per class extra.
• Relying on an old class list. Sunglasses moved to Class 10 on January 1, 2026 (TMEP 1401.16(a)).
• Searching only your own class. Conflicts turn on related goods, not class numbers.

What to Do This Week

1. Write down every product and service the mark is on, and those planned in the next few years.
2. Look up each one in the ID Manual and note the class and exact wording.
3. Mark each item as in use or planned, and collect specimens for the ones in use.
4. Drop items you cannot honestly say you use or intend to use.
5. Run a search that covers related classes.
6. Build a per-class budget for filing and the first ten years.

Frequently Asked Questions

Is There a Limit on How Many Items You Can List in One Class?

The fees are charged per class, not per item, but free-form descriptions over 1,000 characters carry a $200 surcharge per extra 1,000 characters per class. More items in a class also make a random post-registration audit possible once a class has four or more.

Does One Class Protect Against Use in Other Classes?

Registration covers the listed goods, but infringement turns on likelihood of confusion, which looks at related goods regardless of class. A registration for clothing can still matter against a similar mark on closely related goods.

Can You Add a Class After Filing?

Only for items already within your identification that belong in another class; you pay the extra class fee (TMEP 1401.04(b)). New goods need a new application.

Should Each Class Be a Separate Application?

It can be. One multiple-class application gets one certificate (37 CFR 2.86(f)), but a delay or refusal in one class can hold up the rest unless you divide. Separate applications cost the same per class and move independently.

What If the ID Manual Has No Entry for Your Product?

You can write your own description for the $200 per class surcharge, or suggest a new entry; the USPTO says suggestions are reviewed and not added automatically.

How Long Does Registration Take With Several Classes?

The examination runs on the same timeline, but an intent-to-use class can hold up the others at the statement of use stage. Our page on how long trademark registration takes covers each stage.
