There are too many ISO systems and it's confusing which one to choose? No worries! Today, we will explain one by one which type of system certification is most suitable for different enterprises.
1. ISO9001 Quality Management System
The ISO9001 standard is universally applicable. This doesn't mean that the 9001 standard is all-powerful, but because 9001 is a foundational standard, embodying the essence of Western quality management science. It applies to manufacturing enterprises as well as service industries, intermediary companies, sales companies, etc., because quality principles are universal.
Generally speaking, the ISO9001 standard is more suitable for manufacturing enterprises because the content of the standard corresponds well and the processes are clearer, giving a sense of fitting the right place.
Sales companies can be divided into two types: pure sales and manufacturing sales companies. If it is a pure sales company, its products are outsourced or procured, and its product is sales service rather than product manufacturing. Therefore, the planning process should consider the particularity of the product (sales process), which makes system planning easier. If it is a manufacturing sales company, including production in the middle, both production and sales processes should be planned. So when a sales company applies for ISO9001 certification, it should consider its own products and distinguish itself from manufacturing enterprises.
Overall, regardless of the size or industry of the enterprise, currently all enterprises are suitable for ISO9001 certification. Its scope is very broad, suitable for any industry, and it is the foundation and basis for all enterprises to grow and develop. For different industries, ISO9001 has derived various detailed standards, such as quality system standards for the automotive and medical industries.
2. ISO14001 Environmental Management System
ISO14001 environmental management system certification applies to any organization, including enterprises, institutions, and related government units. After certification, it can prove that the organization has reached an international level in environmental management, ensuring control of various pollutants in all processes, products, and activities of the enterprise, establishing a good social image for the enterprise.
Environmental protection issues have increasingly attracted attention. Since the International Organization for Standardization released the ISO14001 environmental management system standard and several related standards, it has received widespread response and attention worldwide. More and more environmentally conscious enterprises have voluntarily implemented the ISO14001 environmental management system.
Generally, enterprises implement the ISO14001 environmental management system in the following situations:
1. Emphasizing environmental protection, hoping to fundamentally achieve pollution prevention and continuous improvement through the implementation of the environmental management system, while promoting the development of clean products, adoption of clean processes, use of efficient equipment, and proper waste disposal.
2. Requirements from related parties. For example, suppliers, customers, bidding, and tendering require enterprises to provide ISO14001 environmental management system certification.
3. Improving enterprise management level and promoting transformation of management models. By controlling the consumption of various resources, comprehensively optimizing cost management.
In summary, ISO14001 environmental management system is a voluntary certification. Any enterprise with a need to improve can implement this certification to enhance its reputation and fundamentally improve management level.
3. ISO45001 Occupational Health and Safety Management System
ISO45001 is an international safety and health management system certification standard, the new version of the original Occupational Health and Safety Management System (OHSAS18001). Its purpose is to reduce and prevent losses of life, property, and time caused by accidents through management, as well as environmental damage.
ISO 45001 occupational health and safety management system applies to any organization's occupational health and safety management system standard. Its purpose is to reduce and prevent losses of life, property, and time caused by accidents through management, as well as environmental damage.
We usually refer to ISO9001, ISO14001, and ISO45001 together as the three systems (also called the three standards).
These three system standards apply to all industries, and some local governments even provide financial subsidies to certified enterprises.
4. GB/T50430 Construction Quality Management System
Any enterprise engaged in construction engineering, road and bridge engineering, equipment installation, and other related projects must have corresponding qualification certificates, including the GB/T50430 construction system.
In bidding activities, if you are an enterprise in the construction industry, you are likely familiar with GB/T50430 certification, especially since having three certificates can increase bid scores and improve the winning rate.
5. ISO27001 Information Security Management System
1. Industries that treat information as a lifeline:
1. Financial industry: banks, insurance, securities, funds, futures, etc.
2. Telecommunications industry: telecom, Netcom, mobile, Unicom, etc.
3. Shell companies: foreign trade, import and export, HR, headhunting, accounting firms, etc.
2. Industries highly dependent on information technology:
1. Steel, semiconductors, logistics
2. Electric power, energy
3. Outsourcing (ITO or BPO): IT, software, telecom IDC, call centers, data entry, data processing, etc.
3. Industries with high technical process requirements and coveted by competitors:
1. Pharmaceuticals, fine chemicals
Introducing an information security management system can coordinate information management in various aspects, making management more effective. Ensuring information security is not just about having a firewall or hiring a company that provides 24-hour information security services; it requires comprehensive integrated management.
6. ISO20000 Information Technology Service Management System
ISO20000 is the first international standard for IT service management system requirements. It adheres to the philosophy of "customer-oriented, process-centered" and emphasizes continuous improvement of IT services provided by organizations according to the PDCA (Deming quality) methodology. Its purpose is to provide a model for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving the IT service management system (ITSM).
ISO 20000 certification is suitable for IT service providers, which can be internal IT departments or external service providers, including (but not limited to) the following categories:
1. IT service outsourcing providers
2. IT system integrators and software developers
3. Internal IT service providers or IT operation support departments within enterprises
7. ISO22000 Food Safety Management System
ISO22000 Food Safety Management System Certificate is one of the essential certificates in the catering industry.
The ISO22000 system applies to all organizations throughout the entire food supply chain, including feed processing, primary product processing, food manufacturing, transportation and storage, as well as retailers and the food service industry.
It can also be used as a standard basis for organizations to conduct second-party audits of their suppliers, and of course, it can be used for third-party commercial certification.
8. HACCP Hazard Analysis and Critical Control Points System
The HACCP system is a preventive food safety control system that assesses potential hazards in food processing stages and then takes control measures.
This system mainly targets food production enterprises and focuses on the hygiene and safety of the entire production chain (responsible for consumer life safety).
Although both ISO22000 and HACCP systems belong to food safety management, they differ in scope: the ISO22000 system applies to various industries, while the HACCP system only applies to the food and related industries.
9. Product After-Sales Service Certification

Product After-Sales Service Certification GB/T27922 is a service certification category that issues a "Service Certification Certificate." Any legally operating enterprise within the People's Republic of China can apply for product after-sales service certification, including enterprises manufacturing tangible goods, selling tangible goods, and providing intangible goods (services).
Products are items entering the consumer field. Besides tangible products, products also include intangible services. Both industrial and consumer goods belong to products.
Tangible products have external forms and intrinsic quality as well as promotional components, such as quality, packaging, brand, shape, style, tone, culture, etc.
Intangible products include labor and technical services, such as financial services, accounting services, marketing planning, creative design, management consulting, legal consulting, programming, etc. Intangible products generally occur alongside tangible products and infrastructure, such as airline services, hotel services, beauty services, etc.
Therefore, any production, trade, or service enterprise with independent legal status can apply for product after-sales service certification.
10. Enterprise Credit Evaluation (AAA)
The enterprise credit evaluation standard GB/T 23794-2015 refers to an independent, neutral professional institution entrusted by the evaluation subject, which, based on the principles of "objective, fair, and scientific," uses standardized evaluation items and content as the basis, follows standardized procedures and scientific methods to investigate, audit, and comprehensively evaluate the behavior, ability, and trustworthiness of the evaluated subject in fulfilling corresponding economic commitments, and expresses the evaluation results with intuitive symbols.
Enterprise credit rating is the identity card for shaping the enterprise's credit image in market activities. It is an asset certificate for enhancing brand value and competitiveness, a reliable pass for obtaining government support, investment promotion, financing guarantees, and bank loans. Enterprise credit is not only a capital and resource but also a productivity factor. Without good credit construction, an enterprise may be vulnerable in market competition. Credit rating improves enterprise credit transparency, showcases the enterprise's integrity to society, establishes a good credit image, and enhances core competitiveness.
11. Enterprise Integrity Management System Certification
Enterprise Integrity Management System Certification is a certification service approved by the National Certification and Accreditation Administration, conducted by certification bodies based on the national standard: "GB/T31950-2015 Enterprise Integrity Management System," auditing the management technology, business operations, and related institutional arrangements for enterprise credit risk prevention, control, and transfer.
The qualification of Enterprise Integrity Management System Certification can serve as strong proof of enterprise credibility in government procurement, bidding, investment promotion, business cooperation, and other activities, helping to enhance market competitiveness and bidding ability. In some projects, enterprises holding the "Enterprise Integrity Management System Certificate" can receive direct bonus points during the bidding process.
12. Enterprise Social Responsibility Management System Certification
The Enterprise Social Responsibility Management System is certified based on the SA8000:2014 standard. The standard covers areas including child labor, occupational health and safety, freedom of association and collective bargaining, discrimination, punishment, working hours, remuneration, and management systems, aiming to protect labor environment and conditions, labor rights, etc., applicable to organizations of all industries and sizes.
SA8000 measures an organization's social performance in eight important aspects of workplace social responsibility, while using management system elements to promote continuous improvement of this standard in all aspects. The standard is strict, ensuring that supply chains meet the highest social responsibility requirements without affecting business interests, thus highly praised by leading brands and industry leaders. It has helped over two million workers obtain working conditions that meet ethical standards.
Implementing a social responsibility management system can improve enterprise management capabilities, enhance employee relations, effectively attract talent and enable high employee performance; improve corporate social image and gain competitive advantages in product sales; optimize relationships with corporate clients, stabilizing and sustaining business relationships; reduce risks of liability accidents, public exposure, and legal disputes, minimizing potential business risks such as work injuries or fatalities, lawsuits, or loss of orders.
