China Trademark Classification Search Guide for Brand Owners

If you are trying to protect a brand in China, the classification search is where your strategy either holds up or falls apart. Get it right, and your trademark blocks copycats before they start. Get it wrong, and you may find a near-identical mark sitting in a class you never thought to check — completely out of your control, and completely legal for someone else to use.

This guide walks brand owners through how China’s classification system works, what changed with the 2026 update, how to run a proper classification search, and how to build a class-selection strategy that protects your brand without wasting your registration budget.

What Is China Trademark Classification and Why Does It Matter?

The Nice Classification and CNIPA’s Subclass System

China’s trademark classification system is built on the Nice Classification, an international framework maintained by the World Intellectual Property Organization (WIPO) and used by roughly 150 trademark offices worldwide. The version currently in force is the 13th Edition (2026 Text), which the China National Intellectual Property Administration (CNIPA) adopted for all applications filed on or after January 1, 2026 [1][2].

The system divides every conceivable good or service into 45 classes. Classes 1 through 34 cover goods — physical products like cosmetics, machinery, or clothing. Classes 35 through 45 cover services — everything from advertising and retail to legal and scientific services.

China layers a domestic framework on top of the international system: the 《类似商品和服务区分表》 (Classification Table of Similar Goods and Services), published and maintained by the CNIPA Trademark Office. This table breaks each of the 45 classes down further into subclasses (类似群), identified by four-digit codes. Class 25 (clothing, footwear, headgear), for instance, splits into subclasses such as 2501 (clothing), 2502 (baby textiles), and 2507 (footwear).

Why Classification Determines the Scope of Your Protection

Here is the part brand owners underestimate most often: a Chinese trademark registration only protects the specific goods and services you actually list. It does not protect your brand name in general — it protects your brand name for the classes and items you filed.

If you skip a class that turns out to matter — a future product line, a licensing category, an e-commerce service — nothing stops a competitor from registering an identical or confusingly similar mark there. That gap can block your own expansion, create consumer confusion, or hand a bad-faith filer leverage over your brand in a market you have not even entered yet.

Trademark Law of the People’s Republic of China, Article 3: Registered trademarks approved by the Trademark Office enjoy exclusive rights protected by law, extending to goods trademarks, service marks, collective marks, and certification marks [4].

This is compounded by China’s first-to-file principle: rights go to whoever files first, not whoever used the mark first. YCIP has covered how this system reshapes strategy for foreign brands in our guide to China’s first-to-file system. Combined with a classification gap, first-to-file means the cost of an incomplete search is rarely just inconvenience — it can mean losing the class entirely to someone else.

Goods vs. Services: The Practical Distinction

For brand owners new to the system, the goods/services split (Classes 1–34 vs. 35–45) is the first fork in the road. A company that manufactures electronics needs Class 9. A company that also runs retail stores or an online shop selling those electronics may separately need Class 35. A company offering repair services for those same electronics may need Class 37. One product line can easily touch three or four classes once you account for how it is made, sold, and serviced.

How to Conduct a China Trademark Classification Search: Step-by-Step

Method 1: The Official CNIPA Channel

The single most authoritative source for classification data is CNIPA’s own Trademark Office portal. The official trademark search system is accessible at sbj.cnipa.gov.cn after account registration, and it is the only government-operated platform covering every pending, registered, opposed, and cancelled mark in China [3]. From the portal, applicants can navigate to the classification section and download the current 《类似商品和服务区分表——基于尼斯分类第十三版（2026文本）》.

The tradeoff is accessibility: the interface is Chinese-only, and self-service search without local-language fluency or a filing account is genuinely difficult for most overseas applicants. YCIP’s own walkthrough of the CNIPA search system covers the account setup and navigation in detail.

Method 2: Professional Platform Search

Professional IP platforms — including the tools YCIP uses for client searches — offer keyword-based classification matching. An applicant types in a product or service description, and the platform returns the likely class and subclass matches, cutting a process that can take hours of manual table-reading down to minutes.

Caution: Third-party platform data can lag behind official CNIPA updates, particularly during a classification transition year like 2026. Treat platform results as a starting point, not a final answer, and verify anything class-critical against the official table.

Method 3: Self-Guided Table Search

For brand owners who want to understand the underlying logic rather than just get an answer, the classification table follows two different sorting rules:

• Goods are classified primarily by function, purpose, or raw material.
• Services are classified by industry, service purpose, and target audience.

Search Principles That Actually Protect Your Brand

A classification search that only checks for identical, currently registered marks is not a real search. A complete search needs to cover:

• Valid registered trademarks
• Published pending applications
• Applications currently under examination
• Marks under opposition, cancellation, or invalidation proceedings
• Well-known trademarks, which can receive cross-class protection beyond their registered classes

Cross-class and cross-subclass searching matters just as much. Products in different classes can still be treated as similar if they share function, usage, distribution channels, or sales methods — Class 9 electronics and Class 35 e-commerce services frequently require a joint search, and antibacterial hand sanitizer in Class 5 needs cross-checking against hand cream in Class 3. Applicants planning a full filing strategy may also want to review YCIP’s broader complete guide to China trademark search for the mechanics of running these checks end to end.

The 2026 Classification Update: Key Changes You Must Know

Three Core Changes Behind the 2026 Text

Effective January 1, 2026, CNIPA implemented the 13th Edition of the Nice Classification (2026 Text) through its official Guidebook on Classification of Goods and Services [1]. The update introduces three structural changes that directly affect how brand owners should search and file:

1. Cross-class migration of goods and services — certain product and service categories have moved to different classes entirely
2. Addition of new economy categories — emerging technology and service categories now have dedicated classification coverage
3. Optimization of similar subclasses — the internal logic for determining what counts as “similar” within a class has been refined [1][6]

Reclassifications Brand Owners Are Most Likely to Hit

The table below summarizes the highest-impact changes for consumer and industrial brand owners:

The eyewear shift is a useful illustration of the transition’s mechanics: goods filed before January 1, 2026 remain valid under their original Class 9 registration, but any new filing for the same goods now falls under Class 10. Existing registrations are not automatically migrated to the new class [8].

What This Means for Your Search Process

Important: When searching in 2026 and beyond, check both old and new class records for any product that migrated. For eyewear, that means searching historical Class 9 filings alongside new Class 10 applications to see the full conflict picture. Skipping either side of that split search leaves a real blind spot.

This dual-class search obligation adds real cost and complexity to searches conducted during the transition period, and it is not optional — a search that only checks the new class will miss every pre-2026 registration still sitting in the old one [8]. Do not reuse a classification list from a prior filing round without re-verifying it against the 2026 table; a subclass code that was accurate in 2024 may no longer be current.

Strategic Class Selection: Protecting Your Brand the Right Way

The Tiered Approach to Class Selection

How many classes you need depends on where your business actually is, not where you hope it will be in five years. Industry practice generally follows a three-stage model:

The Subclass Coverage Rule

Within whichever classes you choose, coverage inside the class matters just as much as the class itself. CNIPA generally presumes goods or services within the same subclass are similar to one another — which means registering only one item in a subclass leaves every other item in that same subclass open to a competitor.

Practical rule: Select at least one item in every subclass relevant to your business within your target class. For Class 25 (clothing), that means covering 2501 (clothing), 2507 (footwear), and 2508 (hats) individually rather than assuming one filing protects the whole class.

The Broad-to-Narrow Filing Method

For the classes that matter most to your core business, a broad-to-narrow approach gets more protection per filing fee:

1. Start with the core, highest-priority goods or services
2. Add items using broad “upper-concept” descriptions that cover multiple specific products at once
3. For example, in Subclass 0306, filing under the umbrella term “cosmetics” already covers narrower items like lipstick, eyeshadow, and face cream

This method maximizes protection per class filed and gives you more room to demonstrate use later if a registration ever faces a non-use cancellation challenge — always prioritizing the classes tied directly to your core business before layering on adjacent or purely defensive categories. For brand owners weighing a defensive filing strategy on top of core coverage, YCIP’s guide to defensive trademark strategies in China goes deeper into where that budget is best spent.

The Class 35 Debate: Do You Really Need It?

What Class 35 Actually Covers

Class 35 is the single most argued-about class in Chinese trademark practice, and for good reason — it covers advertising, business management assistance, and the often-misunderstood service item “sales for others” (替他人推销). CNIPA addressed the confusion directly in its Guidance on the Application and Registration of Class 35 Service Trademarks, issued December 7, 2022 [9].

CNIPA Guidance on Class 35 (2022): The defining feature of Class 35 services is that they are provided “for others” rather than performed for the rights holder’s own business needs. A general goods-manufacturing enterprise that only produces or sells its own products does not need to register a trademark in Class 35, and using a brand name on a storefront to sell one’s own goods does not constitute use of “sales for others” services [9].

Two Schools of Thought

Chinese courts have not always agreed with the administrative reading. In one frequently cited Guangdong High People’s Court decision, the court found that retail activity conducted through stores or supermarkets could be treated as similar to the “sales for others” service item, based on how the relevant public actually perceives that activity [10]. The 2022 Guidance responded to this tension directly, but it did not eliminate it — enforcement outcomes still depend heavily on the specific evidence a rights holder can present.

Who Should Actually File in Class 35

In practice, Class 35 registration is genuinely useful for:

• Retail and franchise operators
• Businesses running their own online stores or e-commerce storefronts
• Brands engaged in licensing arrangements
• Companies offering commercial or marketing services to third parties

Many e-commerce platforms now require Class 35 registration simply to open an official brand store, independent of whether the underlying legal necessity applies to a given seller. For brand owners weighing this against China’s broader retail and marketplace requirements, YCIP’s guide on selling on Tmall covers the platform-side documentation implications in more detail.

Warning: Class 35 is not a universal defensive shield. A registration held but never actually used “for others” remains exposed to non-use cancellation after three years, regardless of how the mark is used elsewhere in the business.

YCIP’s recommendation: evaluate your actual business model rather than filing in Class 35 by default. Retail, franchise, and e-commerce operators generally benefit from the registration. Pure manufacturers selling only their own goods face a lower administrative necessity, though the class is still worth considering ahead of future expansion into services.

Common Classification Mistakes That Cost Brands Their Protection

Search and Data Mistakes

Searching only core classes, ignoring related classes. Cosmetics companies frequently register Class 3 and stop there, missing Class 5 (medicated cosmetic ingredients), Class 21 (cosmetic applicators), and Class 35 (retail services) — any of which a competitor can occupy.

Relying solely on third-party platforms. Platform data can lag behind official CNIPA updates, and a stale subclass code is functionally the same as no search at all if it misses a live conflict.

Intuitive classification without research. Filing on instinct tends to cover only the obvious product category while ignoring sales and packaging categories. Agricultural feed sits in Class 31, for example, but fresh produce retail sits in Class 35 — two classes a purely product-focused search would miss entirely.

Description and Filing Mistakes

Vague or non-standard item descriptions. CNIPA examiners expect standard terminology drawn directly from the Classification Table. A description that deviates from the approved wording risks outright rejection rather than simple clarification.

Reusing old registration lists after 2026. Given the scope of the 2026 reclassification, a project list built before January 1, 2026 may already be misaligned with current subclass codes — always re-verify against the current table before refiling.

Over-refining goods and services. Piling on excessive numbers of narrow, specific items inside a single subclass adds cost without adding protection — CNIPA does not expand the scope of protection based on item count within a subclass. If your search or filing strategy is turning up more open questions than answers, YCIP’s guide on common IP mistakes foreign businesses make in China covers the broader pattern these classification errors tend to fit into.

Legal Framework: Key Provisions Governing Trademark Classification in China

Primary Legislation

Trademark Law of the People’s Republic of China, Article 2: A trademark is a sign used to distinguish the source of goods or services, encompassing both goods trademarks and service marks; provisions governing goods trademarks apply equally to service marks [4].

Trademark Law of the People’s Republic of China, Article 8: Following the current amendment, mandatory registered-trademark use is limited to cigarettes, cigars, and packaged tobacco products. No service category — including Class 35 — carries a mandatory registration requirement [4].

Classification-Specific Regulations

Principles Every Applicant Should Internalize

• First-to-file: rights go to the first party to file, not the first to use the mark in commerce
• Search is not mandatory, but is strongly advisable: Chinese law does not require a pre-filing search, yet skipping one is the single most common cause of preventable rejections and disputes
• 10-year protection term: counted from the date of registration approval
• Non-use cancellation: any registered mark unused for three consecutive years can be cancelled on request by any party

China Trademark Statistics 2026: The Landscape at a Glance

Why Scale Changes Your Filing Calculus

CNIPA’s official mid-year data release for the first half of 2026 confirms what practitioners have felt for several years: China’s trademark register is enormous and still growing quickly [11]. With well over 50 million valid registered trademarks on record and hundreds of thousands of new applications filed every month, the odds of an unprotected class or subclass being claimed by someone else keep rising, not falling.

These figures come from CNIPA’s official statistical release for the first half of 2026 [11]; brand owners working with an agent should ask for the most current quarterly breakdown, since CNIPA publishes updated figures on a rolling basis.

What the 2026 Update Adds to the Landscape

Beyond the sheer registration volume, the 2026 classification changes introduced new coverage for emerging categories — including agricultural robotics and AI-as-a-service — alongside the cross-class migrations already discussed [1]. For brand owners in technology-adjacent industries, this means the classification search itself has grown more complex, not less, even as the underlying goal — comprehensive, gap-free protection — has not changed.

Frequently Asked Questions

What is the difference between the Nice Classification and China’s classification system?

China follows the international Nice Classification’s 45-class structure but layers its own 《类似商品和服务区分表》 on top, adding four-digit subclass codes, additional China-specific items marked “C,” and its own similarity presumptions within each subclass. Filing in China means working from the Chinese Classification Table, not the raw Nice Classification alone.

How many classes should I register my trademark in?

It depends on your business stage: 3–5 classes for a startup covering core operations, 10–15 for a growth-stage company covering its supply chain and near-term expansion, and full 45-class coverage only for mature brands prepared to manage the associated non-use cancellation risk.

What happens if I choose the wrong classification?

Consequences range from outright application rejection to registration gaps that leave your brand unprotected in classes competitors can freely claim, weakened enforcement options, blocked future expansion, and the added cost of refiling.

Can I register one trademark across all 45 classes in China?

Yes — China supports multi-class applications in a single filing. The tradeoffs are cost (official fees apply per class), longer examination timelines for large filings, and elevated non-use cancellation exposure if you cannot demonstrate genuine use across every class claimed.

Do I need to register in Class 35 if I only sell my own products?

Administratively, no — CNIPA’s 2022 Guidance states that manufacturers selling only their own goods do not need Class 35. Practically, many e-commerce platforms require it for store setup, and some courts have found retail activity similar enough to “sales for others” to matter in enforcement, so retail and franchise operators should still consider it.

How often does China update its trademark classification?

China updates its Classification Table annually in step with WIPO’s Nice Classification revisions, with new versions typically taking effect January 1. The most recent major update, the 13th Edition (2026 Text), took effect January 1, 2026.

What is a subclass (类似群) and why does it matter?

A subclass is a four-digit subdivision within each of the 45 classes. CNIPA generally presumes items within the same subclass are similar to one another, so comprehensive protection requires covering every relevant subclass within your target class — not just one item inside it.

How do I find the correct classification for my product or service?

Three approaches work best in combination: search the official CNIPA classification table directly, use a professional platform for fast keyword-based matching, and cross-verify anything class-critical against the official table before filing.

Are there new classes added in the 2026 update?

The 45-class structure itself is unchanged, but the 2026 update added new economy categories for emerging technologies, migrated roughly ten groups of high-frequency goods and services between classes, and introduced new subclasses such as Class 10’s Subclass 1011 for eyewear.

Conclusion: Get Your Classification Right the First Time

China’s trademark system rewards precision and punishes shortcuts. A classification search that misses a subclass, ignores the 2026 reclassification, or skips a related class isn’t a minor oversight — under a first-to-file system, it’s an open invitation for someone else to take what should have been yours.

The good news is that none of this requires guesswork. A properly scoped classification search, matched to a tiered filing strategy built around your actual business stage, closes the gaps that competitors and bad-faith filers look for. Whether you are filing your first mark in China or auditing an existing portfolio against the 2026 changes, getting the classification right at the outset is far cheaper than fixing it after a conflict has already surfaced.
