For companies engaged in food packaging, a common confusion arises: customers require compliance with national standards, but there are so many standard documents available—GB, GB/T, industry standards, and enterprise standards. Which one takes precedence? In reality, the food packaging standard system is not as complicated as it seems. It resembles a three-tier pyramid: national standards at the top, industry standards in the middle, and enterprise standards at the bottom. The hierarchy is clear, and they complement each other. Understanding this system not only helps you confidently handle factory audits but also enables you to quickly determine whether adjustments are needed when standards are updated. This article starts by explaining the structure of the system, helping you clearly understand the logic of the food packaging standard system all at once.
National Standard, Industry Standard, Corporate Standard: The Relationship Between the Three Levels
The first level of the food packaging standard system is the national standard, denoted by GB (compulsory) and GB/T (recommended). Compulsory national standards are the baseline; non-compliance is illegal, such as safety limit standards for materials in contact with food. Recommended national standards summarize industry best practices and are voluntary for enterprises to adopt. However, once declared on a contract or packaging, they must be followed. The second level is industry standards, denoted by codes such as QB (light industry), BB (packaging), and SN (inspection and quarantine), established by various ministries. These standards elaborate and supplement national standards, such as specific testing methods for certain types of packaging containers. The third level is enterprise standards, denoted by Q/, formulated by enterprises themselves. These standards must be at least equal to or stricter than national and industry standards. Once registered, enterprise standards have legal effect.
The relationship among the three can be summarized as follows: national standards provide the baseline, industry standards elaborate on it, and enterprise standards are stricter. When a customer says the product meets national standards, it means the minimum requirement is to satisfy mandatory national standards. If they say it meets industry standards, it means it satisfies specific technical requirements of a particular industry on top of national standards. Large brand customers often require your enterprise standards to be stricter than national standards, which is the common concept of internal control standards during factory audits. Understanding this hierarchical relationship will help you know which direction to prepare your documentation.
Food Contact Materials Key National Standards: GB 4806 and GB 9685
In the food packaging standard system, there are two national standards that are indispensable—constitutional-level documents. The first is the GB 4806 series, which outlines the general safety requirements for food contact materials and articles, including sensory requirements, physicochemical indicators, and migration test methods. It serves as the overall framework for food packaging compliance. The second is GB 9685, which regulates what additives can be used and in what quantities—namely, the list of permitted additives and their usage limits for food contact materials. Every substance in plasticizers, antioxidants, and color concentrates must be found in GB 9685 to be legally used.
Many factories, when asked for the first time by customers whether they comply with GB 4806, mistakenly believe that submitting a sample for testing and obtaining a report is sufficient for compliance. In reality, these two standards are dynamically updated. The list of additives in GB 9685 is continuously expanded based on risk assessment results, and the GB 4806 series is also under ongoing revision. Compliance is not a one-time report matter; it involves continuous management throughout the entire chain, including raw material acceptance, production formulation, and finished product testing.

What standards should be considered for export markets?
If your product is exported, the food packaging standard system must switch from the domestic version to the international version. Major markets such as the US, EU, Japan, etc., each have their own regulatory systems: exporting to the US requires compliance with FDA 21 CFR, and food contact materials must meet migration limit requirements; exporting to the EU requires compliance with EU 10/2011 regulations and EFSA’s assessment opinions; exports to EU countries such as Germany often require LFGB certification; exports to Japan must comply with the container and packaging specifications under Japan’s Food Sanitation Law. These regulations and national standards follow a similar logic—list plus limit management—but the specific substance lists and limit values differ significantly, and domestic test reports cannot be directly applied.
In practice, the safest approach for export companies is dual compliance: domestic sales products are managed according to GB 4806 and GB 9685, while export products are tested according to the target market regulations in addition to national standards. This ensures the stability of the domestic market and avoids the risk of last-minute testing and delivery delays when exporting.

How to build a standard system for a company
After understanding the three levels and core standards, how can enterprises implement them? It is recommended to follow four steps: first, compile applicable standards, listing all mandatory national standards and relevant industry standards related to the company’s products, and forming a standard inventory; second, establish internal control standards, developing stricter enterprise standards based on national standards and customer requirements, to serve as the basis for procurement, production, and inspection; third, implement raw material control, conveying the requirements of GB 9685 on additives to suppliers, and requiring each batch of raw materials to provide a compliance declaration; fourth, plan testing procedures, arranging factory inspections and type tests according to the required items and frequency specified by the standards, and keeping complete test records.
The greatest benefit of this system is not just to pass inspections, but to make quality costs predictable. With raw materials compliant, the pass rate of finished products naturally improves; with clear standard records, clients no longer panic during factory audits; with complete inspection records, quality disputes can be traced back. In the end, the food packaging standard system is not just a document on the wall, but a management tool that runs through the entire process of procurement, production, and inspection.
Summary and Recommendations
The food packaging standard system can be summarized as a three-tier structure: national standards as the foundation, industry standards for detailed specifications, and enterprise standards with stricter requirements. At its core are the two national standards, GB 4806 and GB 9685. For export markets, additional requirements from the target country’s regulations must also be considered. For packaging buyers, choosing a supplier with comprehensive standard management capabilities is far more important than simply comparing prices—because compliance capability directly determines product market access and brand safety.
