Trademark class finder
Describe what you sell in your own words. You get the trademark classes your products fall into, the words that put them there, and what the filing costs at $350 a class.
Product nouns work best. Two lines is plenty.

What a trademark class is
A trademark class is the category your goods or services sit in. The United States uses the Nice Classification, and the edition in force since January 1, 2026 is the 13th edition, version 2026. It has 45 classes: goods are classified in classes 1 to 34, services in classes 35 to 45. Every US application filed since September 1, 1973 has been classified this way.
Two things follow from the goods and services you identify. First, they state what the registration covers. Class numbers organize those goods and services, but they do not define whether two products are related. Second, the USPTO charges by the class, at $350 each, so the class list is also the invoice.
Each class comes with a heading, and the headings are the part that trips people up. USPTO describes them as general indications of the fields the goods or services belong to, which is another way of saying they are labels for a category rather than a description of your products. Most terms drawn straight from the classification are too indefinite to serve as a US identification, so the heading tells you where you are and not what to type into the application.
Which classes brands actually file together
Brands most often file one class. When they file two, the pairs are lopsided: bags pull clothing, jewelry pulls clothing, software pulls hosted services. We parse the USPTO's daily trademark application file. In the file for August 17, 2026, 7,934 applications named at least one class and 1,386 of them, 17.5%, named more than one. The common case is one class. The question is what the other 17.5% put next to it.
Bags are the clearest example. Of the 141 applications naming class 18 in that file, 62 named a second class, and 47 of those 62, 76%, also named class 25 for clothing. Jewelry behaves the same way: 62% of the multi-class class 14 applications carried class 25. Software is the other pole. Class 9 and class 42 appeared together 265 times, more than any other pair, because a brand that ships an app and hosts a service is genuinely in both.

Clothing is the class everything else pairs with, and it rarely pairs back. Class 25 appeared in 844 applications in that file, and three in four named class 25 alone. When a class 25 filing did carry a second class, retail services in class 35 was the most common partner, in 35% of them.
Class 25 and class 35, the e-commerce question
Class 25 is clothing, footwear and headwear. Class 35 is advertising, business management and office functions, and the piece ecommerce founders reach for is retail store services. In the USPTO file summarized above, only 74 of 844 class 25 applications also named class 35, or 8.8%. A website does not turn every goods brand into a class 35 filer.
Under TMEP 1402.11, "sales" is not acceptable service wording. Retail store activities are different: current USPTO guidance recognizes an online retail store featuring the applicant's own goods as a service when the store gives shoppers a place to find, examine and buy a variety of goods. The identification still has to state the activity and the field: online retail store services featuring clothing, not "retail services".
The same test settles the other common pairs. A candle brand selling candles and mugs needs class 4 and class 21 for those goods. A separately identified retail store service may add class 35, but the website alone does not. A software brand shipping a downloadable app and a hosted platform really is in class 9 and class 42. USPTO publishes a map of coordinated classes, the classes it treats as closely related for searching, and the finder shows them on every result. Classification has no bearing on likelihood of confusion in the first place.
What each extra class costs
The base application fee is $350 per class, fee code 7017 on the USPTO fee schedule. USPTO states the point plainly on its own goods and services page: your filing fee is based on the total number of international classes. Three classes is $1,050 before anything else happens.
Two surcharges ride on top, and both are per class. Writing your own goods wording instead of picking pre-approved text adds $200 per class, fee code 7019, and every extra 1,000 characters of that wording adds another $200 per affected class under code 7020. Leaving required fields out adds $100 per class under code 7018. A three-class application written in your own words is $1,650. Four classes on pre-approved wording is $1,400.

Top figure is the base fee. Second figure adds the $200 per class surcharge for writing your own goods wording.
Maintenance filings between years five and six and again between years nine and ten are charged per class too. Price the whole filing before you send it. That calculator runs the full fee schedule against your class count.
From class to filable wording
A class is not an identification. The application asks what you sell, and TMEP 1402.01 wants that answer specific, definite, clear, accurate and concise. Wording broad enough to span more than one class is indefinite by definition. This is where the USPTO ID Manual earns its place: it is USPTO's own list of pre-approved identifications, already classified, and picking from it keeps you at $350 a class.

Filed, and narrowable only
Get it right before you send it, because the edit only runs one way. After filing you may clarify or limit the identification, never broaden it, so "candles" can become "scented soy candles" and it can never become "candles and mugs". A class you left off is a new application at the current fee, with today's filing date rather than the one you already have.
Vague wording is expensive in a second way. USPTO warns that an identification that is too vague may lead to denial of a filing date, and the filing date is the thing you were buying. Take the matched nouns the finder gives you, search each one in the ID Manual, and file the entry that comes back.

After the class is chosen
A pending application is enough for Amazon Brand Registry. You do not have to wait for registration to enroll. The Brand Registry checker tests your filing against all five requirements. The guide on what Brand Registry asks for before you can enroll sits behind it.
Once it registers, watch the goods and services you filed and the related fields customers may expect from the same source. A US trademark watch on your brand names reads new USPTO applications every day and emails you when one reads close to yours. When somebody is trading on your name rather than filing on it, what a trademark demand letter can and cannot do is the next thing to read, and a free scan of your storefront shows whether your product photos are already on somebody else's listings.
Common questions about trademark classes
What is a class in a trademark search? +
A class is the category your goods or services sit in under the Nice Classification. There are 45 of them: classes 1 to 34 for goods, classes 35 to 45 for services. The goods and services you identify set the registration's scope; the classes organize them and set the price at $350 each. Classification has no bearing on whether two marks are confusingly similar.
What are the 45 classes of trademarks? +
Classes 1 to 34 cover goods and classes 35 to 45 cover services. The ones consumer brands use most are 3 cosmetics, 4 candles, 5 supplements, 9 electronics and software, 14 jewelry, 16 stickers and stationery, 18 bags, 21 mugs, 24 bedding, 25 clothing, 28 toys, 35 retail, 41 courses and 42 hosted software. The full list is above.
What is class 25 and 35 in trademarks? +
Class 25 is clothing, footwear and headwear. Class 35 is advertising and business services, including retail store services. They are not a default pair. Merely selling a shirt does not add a service, but a distinct online retail store service can qualify even when the store features your own goods. File only the goods and services your mark actually identifies.
Can I do a trademark search myself? +
Yes. Classification, the USPTO ID Manual and the trademark search system are public and free, and this page runs the classification half in your browser. What you cannot skip is reading the results: a knockout search that finds nothing is not a clearance opinion.
Can I add a class later? +
Not to the same application. After filing you may clarify or limit the goods you listed, never broaden them, so a class you left out means a new application with its own $350 per class fee and its own filing date. Get the class set right before you file.
