China Trademark Classification Strategy for Foreign Brands: A Complete Nice Class Filing Guide

Introduction

Registering a trademark in China is straightforward on paper. You file an application with the China National Intellectual Property Administration (CNIPA), wait for examination, and receive your registration certificate. The strategic challenge — and the reason many foreign brands lose protection — lies in selecting the right trademark classes.

China uses the Nice Classification system (45 classes: 34 for goods, 11 for services), the same international framework used in most countries. But the way CNIPA interprets class descriptions, examines applications, and treats “subclass” conflicts differs significantly from Western practice. A trademark registration that covers all the right classes in the United States or Europe may leave critical gaps in China.

This guide explains how to build a defensive trademark classification strategy in China, common mistakes foreign brands make, and how to structure your applications for maximum protection in the Chinese market.

How the Nice Classification Works in China

China adopted the Nice Classification and updates its official classification table with each new edition (currently the 12th edition). The 45 classes are organized as follows:

• Classes 1–34: Goods (chemical products, machinery, clothing, food, electronics, etc.)
• Classes 35–45: Services (advertising, insurance, telecommunications, education, legal services, etc.)

Each class contains a class heading (a general description) and thousands of specific goods or services items. When you file a trademark application in China, you must list the specific goods or services you want to cover, not just the class number. CNIPA examines each item individually against prior marks in the same subclass.

For example, “clothing” falls under Class 25, but within Class 25 you have subclass 2501 (garments), 2507 (footwear), 2508 (headwear), and 2509 (hosiery). A trademark registered for “clothing” in subclass 2501 will not automatically block a competitor from registering the same mark for “shoes” in subclass 2507 if the subclasses are deemed dissimilar.

The Chinese Subclass System: Why It Matters

This is where many foreign applicants go wrong. China divides each Nice class into subclasses — functional groupings of similar goods or services. CNIPA examiners evaluate conflicts at the subclass level, not the class level.

In trademark examination practice, goods or services within the same subclass are presumed to be similar, and goods or services in different subclasses are presumed dissimilar — unless there is evidence of cross-subclass similarity. This means:

• A prior registration covering subclass 2501 (garments) may not prevent registration of a similar mark in subclass 2507 (footwear), even though both are in Class 25.
• But if the goods are functionally related (e.g., “computer software” in Class 9 and “software design services” in Class 42), CNIPA may find a likelihood of confusion across classes.

The practical implication: you cannot simply file for “all goods in Class 25” or rely on a class-heading filing. You must identify and list the specific subclasses that cover your products. An experienced Chinese trademark agent will help you map your products to the correct subclass items using the official Chinese-language classification table.

The Chinese subclass numbering system uses a six-digit format: the first two digits are the class number, the last four identify the subclass within that class. For example, subclass 250101 is the first subclass within Class 25.

Core Classes Foreign Brands Always Need

Every foreign company selling products in China should secure at minimum the classes directly covering their goods or services. Here is a quick reference for common industries:

Defensive Class Filing Strategy

Beyond your core product or service classes, a defensive filing strategy protects your brand against unrelated third-party registration that could dilute your mark or confuse consumers. Consider registering in:

• Class 35 (Advertising and Business Management): Covers retail services, online sales platforms, import-export agency services, and business management. Even if you do not consider yourself a “retailer,” if you sell directly to Chinese consumers online, you need Class 35.
• Class 9 (Scientific and Electrical Apparatus): Covers downloadable software and mobile applications. If your brand has an app — even a free one — Class 9 is essential in the digital economy.
• Class 42 (Scientific and Technological Services): Covers software as a service, cloud computing, and industrial design. Relevant for any brand with a technology component.
• Class 16 (Paper Goods and Printed Matter): Covers packaging, instruction manuals, and promotional materials bearing your brand. Often overlooked but useful for consumer goods companies.
• Class 41 (Education and Entertainment): Covers training services, workshops, and online content. Relevant if you run brand events, training programs, or publish content.

The goal is to prevent a third party from registering your brand name in an adjacent class and benefiting from your reputation — a common tactic among Chinese trademark squatters.

The Retail and Wholesale Trap: Class 35

Class 35 is the most misunderstood class for foreign companies entering China. It covers “advertising; business management; business administration; office functions” — including retail and wholesale services.

Here is why it matters: in many Western jurisdictions, a trademark registration covering “clothing” (Class 25) is sufficient to cover both manufacturing and retail sale of clothing. China does not follow this logic. If you operate a branded retail store in Guangzhou or an online store on Tmall, you need a Class 35 registration covering “retail services for clothing” (or whichever goods you sell).

Without Class 35 protection, a third party could — in theory — register your brand in Class 35 and claim rights over retail services under your name. This has happened repeatedly: a foreign brand registers in its product class, opens a store in China, and discovers that a local entity has already registered the brand in Class 35.

The specific items to include in Class 35 for retail operations are:

• “Advertising”
• “Import-export agency services”
• “Sales promotion for others”
• “Provision of an online marketplace for buyers and sellers of goods and services”
• “Presentation of goods on communication media for retail purposes”
• The specific retail or wholesale service item that matches your product category (e.g., “retail services for clothing”)

Six Common Classification Mistakes by Foreign Brands

1. Filing only in the home-country equivalent class. A US trademark for “software” covers Class 9 internationally, but in China you may also need Class 42 for the SaaS platform and Class 35 for the online marketplace. Filing only Class 9 leaves major gaps.

2. Relying on a WIPO Madrid System designation. When a Madrid Protocol application designates China, CNIPA examines it under Chinese classification rules. If the goods and services description was drafted for the home jurisdiction, it may not map cleanly to Chinese subclasses, and CNIPA may issue an office action requiring translation and clarification.

3. Filing in Class 35 without specifying the type of retail service. A registration for the general class heading “advertising; business management; business administration” does not clearly cover retail services. You must list the specific retail service item, such as “retail services for pharmaceutical preparations” or “wholesale services for clothing.”

4. Using English-language descriptions in Chinese applications. CNIPA works exclusively in Chinese. All goods and services descriptions must be selected from the official Chinese-language classification table. A foreign agent who files English-language descriptions (even through the Madrid system) risks receiving office actions or having items rejected as non-standard.

5. Ignoring similar goods across classes. Some goods are functionally related across class boundaries. For example, “computer hardware” (Class 9) and “computer programming services” (Class 42) are considered similar by CNIPA in opposition and cancellation proceedings. A brand in the technology space should cover both.

6. Filing too broadly without subclass mapping. Covering 500 items across 10 classes sounds comprehensive, but if they are not mapped to the correct subclasses, gaps remain. Strategic filing means identifying the specific subclass codes that are most likely to be exploited by squatters and ensuring each is covered with at least one item.

Multi-Class vs. Single-Class Applications: Which to Use

China permits multi-class trademark applications — you can file one application covering multiple Nice classes. The filing fee is calculated per class (with a surcharge for each class beyond the first), so there is no significant cost disadvantage to multi-class filing.

The practical considerations are:

• Single-class applications: Each class is examined and registered independently. If one class faces an office action or opposition, the others proceed unaffected. This gives you more flexibility — you can appeal or amend one class without delaying the others.
• Multi-class applications: A single application covers all classes. If CNIPA issues an office action for any item in any class, the entire application is delayed. On the other hand, managing one application number is administratively simpler, and assignment or licensing of the mark across all classes at once is cleaner.

For foreign brands entering China for the first time, we generally recommend single-class applications. The extra administrative simplicity of a multi-class application is outweighed by the risk that one problematic class could hold up protection for all the others.

How Trademark Squatters Exploit Class Gaps

China operates on a first-to-file trademark system. The first person to file a trademark application in a given class and subclass generally obtains priority, regardless of prior use elsewhere in the world.

Squatters — known in Chinese as “trademark squatters” — systematically search for foreign brands that have registered in their core product class but left adjacent subclasses or related service classes unprotected. They then file in those gaps and either demand a buyout or use the registration to block the foreign brand’s expansion into those areas.

Real-world example: a European luxury clothing brand registered in Class 25 (subclasses 2501–2504 for garments) but did not cover subclass 2507 (footwear) or Class 18 (leather goods). A squatter registered the brand in those gaps and subsequently demanded payment when the brand sought to launch a shoe line in China.

The defense is straightforward: identify all subclasses and related classes that a competitor or squatter might target, and register in them before entering the market. This is significantly cheaper than litigating a bad-faith registration later.

Post-Registration: Expanding Class Coverage

If you registered your trademark in China five years ago and only covered your core product class, it is not too late to expand. You can file new applications in additional classes at any time.

However, be aware that a new application in a new class is a fresh examination. CNIPA will evaluate it against prior marks in that class as of the new filing date. If a squatter has already registered your brand in the class you want to add, you will need to oppose or cancel their registration first — which is a longer and more expensive process.

Timing matters. The best time to file defensive classes is before your brand achieves visibility in the Chinese market. Once your brand is known, squatters become more active.

Frequently Asked Questions

How many classes does a typical foreign brand need in China?
At minimum: the core product or service class, Class 35 (if selling retail or online), and any functionally related service class. For a consumer brand, three to six classes is common. For a diversified manufacturing company, the number can reach 10 or more.

Can I use my home-country trademark description in a Chinese application?
Technically yes through the Madrid System, but it is inadvisable. CNIPA will attempt to reclassify your description using a standard Chinese-language cross-reference table, and items without a corresponding Chinese entry will be rejected. Best practice is to engage a Chinese trademark agent to prepare the specification using the official Chinese classification table from the outset.

What if my trademark covers subclasses I will never use?
That is precisely the point of defensive filing. China has no use requirement during the first three years after registration. After that, a registration is vulnerable to cancellation for non-use. If you defensively filed in a class you do not currently use, be aware that after three years a third party could petition to cancel it. The solution: find a modest but genuine use within the three-year window — even a token product launch.

Is the Chinese classification table available in English?
The official classification table is in Chinese only. Several unofficial English translations exist, but they may not be current with CNIPA’s latest amendments. Work with a trademark agent who uses the current Chinese-language table directly.

How long does a multi-class application take to examine?
CNIPA’s average examination timeline is 4 to 6 months from filing, regardless of the number of classes. If no office action or opposition arises, a multi-class application proceeds to registration on roughly the same timeline as a single-class application.
