If you plan to sell products in China, you need to understand GB standards. You must meet relevant GB standards to legally sell many products in China. These national rules set requirements for safety, quality, and performance across many industries.

GB stands for Guobiao, meaning national standard. China issues these standards through government bodies. Some are mandatory, while others are voluntary. Mandatory GB rules link to safety laws, and authorities can block or recall products that fail to comply.

Many products must pass testing and show proof of compliance before entering the market. Some goods also require China Compulsory Certification (CCC), which works alongside certain GB standards. Knowing which rules apply helps you avoid delays, fines, and rejected shipments.

Key Takeaways

• GB standards are China’s national rules for product safety and quality.
• Many products need testing and approval before sale in China.
• Some goods also require CCC in addition to GB compliance.

Overview of GB Standards

GB standards set the legal and technical baseline for products sold in China. They define rules for safety, quality, and performance that affect design, testing, labeling, and market access. If you sell products in China, you must understand how these standards work and who enforces them.

Definition and Purpose of GB Standards

GB standards, short for Guobiao, are Chinese national standards that govern product compliance across many industries. They apply to consumer goods, industrial equipment, food, electronics, and more. You must follow the relevant GB standard before placing a product on the Chinese market.

These standards protect user safety, product quality, and public health. They also support fair trade by setting clear technical rules. Many Chinese GB standards align with international standards, but China often adapts them to local needs and policies.

GB standards form the foundation of China’s national standardization system and support other compliance programs, such as China Compulsory Certification (CCC).

Types of GB Standards: Mandatory vs. Recommended

Chinese GB standards fall into two main types. You must know the difference because the legal impact is not the same.

• GB (Mandatory standards)
  These standards carry legal force. If a product falls under a mandatory GB standard, you must comply. Authorities can block sales, issue fines, or recall products if you do not meet the rules.
  
  
• GB/T (Recommended standards)
  These standards are voluntary. You do not have to follow them by law, but many buyers and regulators expect compliance. GB/T standards often show accepted industry practice.
  
  

Mandatory standards usually focus on safety, health, and environmental risks. Recommended standards often cover performance, testing methods, and quality benchmarks.

Key Organizations and Regulatory Bodies

Several government bodies manage and enforce Chinese GB standards. Each plays a specific role in national standardization.

Handled quality and inspection duties before merging into SAMR

SAC issues GB and GB/T standards, often together with other ministries. SAMR enforces compliance through inspections, testing, and penalties. You must monitor updates from these bodies because Chinese national standards change often.

Understanding broader compliance frameworks helps you navigate GB standards effectively. Read our guide: 10 Laws in China That Impact International Business for key legal requirements affecting product compliance.

Hierarchy and Categories of Chinese Standards

Chinese standards follow a clear order of authority. National rules sit at the top, while other standards fill gaps for sectors, regions, and companies. You need to know which level applies to your product and which rules override others.

National Standards (GB, GB/T, GB/Z)

National standards form the legal base for product compliance in China. You will see three main codes: GB, GB/T, and GB/Z.

• GB (mandatory): You must meet these standards to sell or import products. A small share of GB standards are compulsory, but they carry legal force.
• GB/T (recommended): You should follow these to show quality and good practice. Many buyers and regulators expect compliance.
• GB/Z (guidance): These offer technical guidance and trial methods. They do not create legal duties.

The Standardization Administration of China (SAC) issues these standards, often with the State Administration for Market Regulation. Some areas involve other bodies, such as the Ministry of Ecology and Environment for pollution and emissions rules.

Industry, Local, and Association Standards

Industry standards apply when no national standard exists or when a sector needs detail. Ministries such as MIIT issue many of these for electronics, telecom, and machinery. You must follow them if your product falls within that regulated scope.

Local standards come from provinces or cities. They address regional needs like climate, safety, or local resources. These standards cannot conflict with national rules.

Association standards come from trade groups. They reflect shared practices within an industry. While not mandatory, buyers often use them as benchmarks.

• National standards always take priority.
• Industry and local standards fill gaps, not replace GB rules.
• Association standards shape market access and tenders.

Enterprise Standards and T Standards

Enterprise standards are rules set by individual companies. You must publish them and ensure they meet or exceed mandatory national standards. Many firms use them to define product quality, testing, and internal control.

T standards are a newer form tied to market-driven innovation. Companies, research groups, and associations develop them together. They move faster than traditional standards and suit new technology.

You should use enterprise and T standards to show control and consistency. Regulators still check them against GB and industry standards. If conflicts arise, higher-level standards prevail.

Manufacturing compliance extends beyond GB standards to include facility-specific regulations. Explore our article, Manufacturing in China: Understanding Industry-Specific Regulations for sector-specific compliance challenges.

Product Compliance Requirements under GB Standards

You must understand how GB standards, also called Guobiao standards, apply to your product, your industry, and your route to market. These rules define when testing is required, which standards apply, and how Chinese authorities judge compliance.

Scope of Products and Industry Applications

Chinese GB standards apply to both imported and locally made products. You must meet the same rules regardless of where you manufacture. These standards support product safety, quality, and performance across many sectors.

Industries most affected include consumer goods, electronics, textiles, toys, machinery, and chemicals. Each industry uses its own set of Chinese GB standards that define test methods, labeling rules, and safety limits.

Some standards apply broadly, while others target a specific use case. For example, GB 18401 sets mandatory safety rules for textile products that touch human skin. If your product falls under a regulated category, customs or market regulators can block sales until you prove compliance.

Mandatory vs. Voluntary Compliance Scenarios

You must follow mandatory GB standards when they protect health, safety, or the environment. These standards use the prefix GB without “/T” and have legal force. Authorities enforce them during customs clearance, inspections, and market checks.

Voluntary standards use the GB/T prefix. You may choose to follow them, but regulators do not require them by law. Many companies still adopt GB/T standards to meet buyer demands or show quality control.

Commonly Applied Product Categories

Some product groups face higher enforcement and stricter testing. You should review these areas early in product development.

High-focus categories include:

• Textiles and apparel: GB 18401 for chemical safety and labeling
• Electrical products: Safety, EMC, and performance GB standards
• Toys and childcare items: Mechanical, chemical, and flammability limits
• Food-contact materials: Migration limits and material restrictions

If your product fits more than one category, you must meet all applicable GB standards. Regulators expect clear test reports, correct labels, and consistent product quality across shipments.

Quality control issues often stem from misunderstanding Chinese compliance requirements. Check out our guide, China Factory Quality Issues: Prevention and Resolution Strategies for methods to resolve manufacturing defects.

Testing, Certification, and Marking Processes

You must complete formal testing, conformity checks, and product marking before you can sell regulated products in China. These steps link GB standards to legal market access and help show that your product meets safety and quality rules.

Role of CNAS-Accredited Laboratories

You must test products against GB standards in laboratories approved by the China National Accreditation Service for Conformity Assessment (CNAS). CNAS checks that labs follow strict rules for staff skills, equipment, and test methods.

For products under the CCC system, you must use labs designated by the certification authorities. Some foreign labs also hold approval for limited product scopes.

• CNAS accreditation confirms test results are valid in China.
• Testing often includes safety, performance, and reliability checks.
• Retesting may apply after design changes or standard updates.

Testing timelines vary by product type. Complex products may need several test cycles.

Conformity Assessment and Documentation

You must complete conformity assessment before certification or customs clearance. This process confirms that your product matches applicable GB standards and related rules set by CNCA.

You need to prepare clear and accurate documents, such as:

• Test reports from CNAS-accredited labs
• Technical files, drawings, and specifications
• Factory inspection records for CCC products

For CCC-listed products, authorities also review your factory’s quality system and may conduct on-site audits.

Incomplete or incorrect documents often cause delays. You reduce risk by keeping records consistent and up to date.

Labeling and Product Marking Rules

You must label and mark products according to GB standards and certification rules. Labels must use simplified Chinese and be easy to read.

Common labeling requirements include:

• Product name and model
• Manufacturer and address
• Safety warnings and usage limits

If your product falls under the CCC catalog, you must apply the CCC mark only after approval. The mark must be the correct size and in the right location.

Incorrect marking can lead to product recalls, fines, or blocked imports.

Legal disputes can arise when products fail to meet GB standards or certification requirements. Review our article, How to Handle Business Disputes in China: Contracts, Arbitration, and Law, covering dispute resolution strategies.

China Compulsory Certification (CCC) and Its Relationship with GB Standards

China requires CCC certification for many regulated products before import, sale, or use in the local market. CCC is linked to GB standards, which define safety and quality rules under CNCA oversight.

Scope of CCC and Product Categories

China Compulsory Certification applies to products listed in the official CCC Catalogue. If your product is on this list, you must obtain CCC certification before customs clearance or sale.

Common covered categories include:

• Electrical and electronic products
• Automotive parts and vehicles
• Power tools and cables
• Household appliances and lighting

CCC uses mandatory GB standards. These standards define test methods, safety limits, labeling rules, and key components. If no GB standard applies, related industry standards may be used.

Selling a non-certified product within scope can lead to shipment holds, fines, or recalls.

Application Procedure and Test Requirements

You apply for China Compulsory Certification through a CNCA-designated certification body. The process has fixed steps and does not allow shortcuts.

Key steps include:

1. Application submission with product details and technical files
2. Type testing at an approved Chinese lab using GB standards
3. Factory inspection to review quality systems and consistency
4. Certificate issuance after all results meet requirements

Testing covers safety, EMC, and performance based on the relevant GB rules. You must submit samples that match your final product.

If you change parts, suppliers, or designs, you may need re-testing. Testing and inspections can take several months, so plan timelines carefully.

CCC Mark and Post-Certification Obligations

After approval, you must apply the CCC mark to each certified product. You can print the mark on the product, nameplate, or approved packaging, following CNCA rules.

After certification, you must:

• Maintain product consistency with tested samples
• Accept annual factory audits by the certification body
• Report changes that affect safety or compliance
• Keep technical records available for review

CNCA supervises enforcement and can suspend or cancel certificates if you fail audits. You are responsible for compliance throughout the product life cycle.

Operating within China's legal framework requires understanding multiple compliance layers beyond product standards. See our article: China's Legal Framework for Foreign Business Operations, explaining how regulations interact.

Comparison of GB Standards with International Standards

GB standards often relate to international standards, but they do not always match. You need to know where they align and where they differ, especially if you sell products in multiple markets.

Alignment and Differences with ISO, IEC, and ASTM

Many GB standards are based on ISO and IEC standards. China uses these references to support global trade and technical consistency. In some cases, GB standards match the international version with minor edits.

Key differences remain. GB standards may change test methods, limit values, or labeling rules. Some GB standards are mandatory, while ISO, IEC, and ASTM standards are usually voluntary.

Common differences include:

• Stricter safety limits for electrical and consumer products
• China-specific testing conditions, such as voltage or climate factors
• Local language requirements for markings and instructions

ASTM standards are less commonly adopted. Extra testing may be needed if ASTM is your main reference.

Impact on Importers and Multinational Manufacturers

If you import or manufacture for China, GB standards affect your product design and approval process. International compliance alone is not enough, even if your product meets ISO or IEC rules.

Mandatory GB standards often support CCC certification. You must pass local testing at approved Chinese labs. This step adds time, cost, and planning.

You should plan for:

• Early gap analysis between your international standard and GB requirements
• Design changes to meet mandatory GB limits
• Separate documentation for Chinese regulators

Aligning GB and international standards early helps reduce rework and avoid delays at customs or during certification.

Supply chain management becomes critical when ensuring GB standard compliance across your vendor network. Read our guide: What To Do When a Supplier in China Won't Fix Defects for quality dispute solutions.
