Why the class you pick decides whether your registration is worth anything
A China trademark registration protects your mark only for the goods and services you actually listed. Nothing more. If you register in the wrong class, or in the right class but the wrong part of it, you can hold a perfectly valid certificate and still be unable to stop someone else from using your brand on the product you care about most.
This is where the majority of foreign applicants lose money. They copy the class they use at home, file in one class, and discover a year later that the registration does not cover the thing they sell.
The two-layer system you have to understand
China follows the Nice Classification — 45 classes, 1 to 34 for goods, 35 to 45 for services. That part is familiar.
What is not familiar is the second layer. CNIPA divides each of the 45 classes into subclasses, called similar goods groups. Each subclass carries a six-digit code. For example, within Class 25 the clothing items sit in one subclass, and footwear sits in another.
The practical consequence is blunt: CNIPA judges similarity mainly within a subclass. Two identical brand names in the same Nice class but different subclasses are often treated as non-conflicting. That cuts both ways — it means a prior mark in a different subclass may not block you, and it also means your registration may not block someone else.
This is why "I registered in Class 25 for clothing" is an incomplete answer. Clothing is not one block. T-shirts, trousers and jackets may sit in a different subclass from socks, and socks in a different one from swimwear.
What this looks like in practice
Think of it as rooms inside a building. The class number is the building. Registration in the building does not give you every room. You get the rooms you named.
An examiner comparing your mark to an earlier one will first ask whether the goods fall in the same subclass. If they do not, the conflict argument usually ends there. If they do, the examiner then runs the same visual, phonetic and conceptual similarity test used everywhere else.
Core classes by industry
These are the classes foreign applicants most often need. Treat this as a starting point, not a filing plan.
Clothing and fashion Class 25 covers clothing, footwear and headwear. Class 18 covers bags, leather goods and luggage — separate class, separate protection. Class 35 covers retail services for clothing. Class 24 covers textiles, towels and bed linen if a home line is planned.
Software and technology Class 9 covers downloadable software and mobile applications. Class 42 covers software as a service, cloud computing and software development. These are not interchangeable: a downloadable app sits in Class 9, a hosted platform sits in Class 42, and a brand with both needs both.
Food and beverage Class 29 covers meat, dairy and processed foods. Class 30 covers coffee, tea and confectionery. Class 32 covers beer and non-alcoholic drinks. Class 33 covers alcoholic beverages. Class 43 covers restaurant and catering services.
Cosmetics and personal care Class 3 covers cosmetics and toiletries. Class 21 covers cosmetic utensils and brushes. Class 44 covers beauty salon and hygiene services.
Manufacturing and machinery Class 7 covers machines and machine tools. Class 12 covers vehicles. Class 37 covers repair and installation services.
Professional services Class 35 covers advertising, business management and retail services. Class 41 covers training and education. Class 45 covers legal and personal services.
The Class 35 trap
Class 35 is the single most misunderstood class for foreign companies, and it deserves its own section.
In many countries, a registration covering "clothing" is enough to cover both making clothing and selling it. China does not work that way. Manufacturing and retail are different things, classified differently.
If you sell directly to Chinese consumers — through Tmall, JD.com, Douyin, WeChat or your own site — you need Class 35 covering retail services for your goods. Without it, a third party can register your brand in Class 35 and claim rights over retail sales conducted under your own name.
The Class 35 items that matter most for a brand selling online are advertising, sales promotion for others, import-export agency services, providing an online marketplace for buyers and sellers, and the specific retail service matching your product category.
A registration for the general class heading alone — "advertising; business management; business administration" — is not enough. The specification must name the retail service you actually operate.
Cross-class similarity
CNIPA will occasionally find two marks similar even in different classes, where the goods or services are closely related. Class 25 and Class 35 are the classic pair, since retail services for clothing are obviously tied to clothing. Class 9 and Class 42 behave the same way for technology brands.
The lesson is not to file blindly in more classes. It is to accept that the boundary is not purely mechanical, and that a search has to consider adjacencies rather than just your own class number.
Defensive filing — how much is enough
Defensive filing means registering in classes you do not yet use, so a third party cannot take your brand in an adjacent category and trade on your reputation.
The classes that most often repay defensive protection:
- Class 35 — retail and marketplace services, if you sell to consumers at all
- Class 9 — if your brand has an app, even a free one
- Class 42 — if there is any technology or software element
- Class 16 — packaging, printed materials and manuals carrying your brand
- Class 41 — if you run training, events or publish brand content
The judgment call is always cost against exposure. Every additional class carries its own official fee and its own examination risk, because a new class is a fresh opportunity to collide with a prior mark. For most small and mid-sized brands, the sensible sequence is: secure the classes you genuinely trade in first, then add the two or three defensive classes where squatting would hurt most.
Six mistakes foreign applicants make
Copying your home-country class. A US or EU registration for software may not capture the SaaS and marketplace layers, which sit in Classes 42 and 35 in China.
Assuming one class covers a product family. A Class 25 registration does not protect bags, which live in Class 18. Streetwear brands have found this out after a factory filed their mark on backpacks.
Filing a class heading instead of specific items. The heading is broad and vague. Examiners read specifications narrowly, and a vague specification can trigger a correction notice.
Assuming a Madrid designation solves classification. A Madrid designation of China is examined under Chinese classification rules. A specification drafted for your home jurisdiction may not map cleanly onto Chinese subclasses, and CNIPA can issue a provisional refusal requiring clarification.
Ignoring subclasses entirely. Two marks in the same class but different subclasses may coexist. If your protection is concentrated in the wrong subclass, you are effectively unregistered for the goods that matter.
Filing too many classes with a loose specification. Cost is not the main risk here. The risk is that a wide, imprecise specification multiplies the number of subclasses you touch, and therefore the number of prior marks you can collide with. A tight specification aimed at goods you actually sell is both cheaper and safer.
How to decide in four steps
Step one — name what you sell today. List the actual products or services, in ordinary words. Not the category, the products.
Step two — map each to a class and a subclass. This is the step that requires the Chinese classification manual, not just the Nice headings. It is also the step where non-specialists most often go wrong.
Step three — add adjacency. Ask which adjacent classes a competitor or squatter could use to confuse your customers. Retail and software are the two most common answers.
Step four — run the search before committing. Class and subclass decisions interact with what is already on the register. A subclass that looks ideal may be crowded with prior marks. Deciding the specification without searching first usually means filing into a wall.
Frequently asked questions
Does one trademark application cover multiple classes in China?
One application covers one mark. You can include multiple classes within a single application document, but each class is charged its own official fee and examined separately. The mark must be identical across the classes.
Does a Class 25 registration protect shoes and bags in China?
Footwear and headwear are in Class 25, but bags and leather goods are in Class 18, a separate class. A Class 25 registration does not protect bags. Brands that sell a full range usually need both.
Do I need Class 35 to sell on Tmall or JD.com?
In practice, yes. Selling through a Chinese e-commerce platform involves retail services, which sit in Class 35. Platforms commonly require a Class 35 registration covering the relevant retail service before allowing a flagship store.
What is the China subclass system?
Each of the 45 Nice classes is divided into subclasses, identified by six-digit similar goods group codes. CNIPA assesses similarity mainly within a subclass, so two marks in the same class but different subclasses may not be considered conflicting.
Can I register in a class I am not yet using?
Yes. China does not require use before filing, and defensive registration in unused classes is common and legitimate. However, a registration unused for three consecutive years can be cancelled by any third party, so defensive registrations need to be managed rather than simply parked.
How many classes should a small brand file in China?
Most small and mid-sized brands start with the classes covering goods they actually sell, plus Class 35 if they sell to consumers directly. Adding two or three defensive classes is worthwhile where squatting would be disruptive, but each class adds cost and a fresh examination risk.
What happens if I choose the wrong class?
You cannot amend an application to add a class. The usual fix is a fresh application in the correct class, which means a new filing date and a new examination. This is why classification decisions should be made before filing rather than corrected after.
