Currently, many of YKK’s production locations have been certified with ISO 9001, ISO 14001, ISO/TS 16949, OEKO-TEX® STANDARD 100, bluesign® system, JISHA OSHMS, JISHA OHSAS, Global Recycled Standard (GRS), and Science Based Targets. Below is a more detailed description of each certification.

ISO 9001

ISO 9001 provides standardized requirements for a best-in-class quality management system, regardless of the products or services the organization produces or its size.
The ISO 9001 standard provides a proven framework for managing quality that leads to the production of consistently higher-quality products. ISO 9001, as well as other ISO standards, have been developed by the International Organization for Standardization (ISO), the world’s largest developer and publisher of international standards.

YKK has acquired ISO 9001 certification in 51 locations as of July 2017.

ISO 14001

ISO 14001 provides the requirements for environmental management systems (EMS).
An EMS that meets the ISO 14001 requirements provides management tools necessary to:
– identify and control the environmental impact of a company’s activities, products or services
– continually improve environmental performance
– implement a systematic approach to setting environmental objectives, achieving those objectives, and demonstrating that those objectives have been achieved

YKK has acquired ISO 14001 certification in 52 locations as of July 2017.

ISO/TS 16949

ISO/TS 16949, in conjunction with ISO 9001, lays out the quality management system requirements for the design, development, production and, when relevant, installation and service of automotive-related products.


YKK has acquired ISO/TS 16949 in 4 locations.


The OEKO-TEX® STANDARD 100 is a globally uniform testing and certification system for textile raw materials, intermediate products and final products at all stages of production.
The certification confirms compliance with laws that control or prohibit certain substances and chemicals.
For details of certification, please contact the YKK company from which you have purchased products.

YKK has acquired OEKO-TEX® STANDARD 100 Product Class I certification in 40 locations as of November 2016.

bluesign® system


The bluesign® system is a solution for the sustainable production of textiles, accessories and trims. It eliminates harmful substances right from the beginning of the manufacturing process and sets and controls standards for environmentally-friendly and safe production. This not only ensures that the final product meets very stringent consumer safety requirements worldwide, but also reassures the consumer that they have secured a sustainable product.

YKK is a bluesign® system partner and has bluesign® Approved products, which require the most stringent standards in the world. Below are some of our bluesign® Approved products.

bluesign® Approved products require certain conditions to be met.
Please contact your nearest YKK office for inquiries relating to bluesign® Approved products.

YKK is a bluesign® system partner in 17 locations as of July 2017.


The Occupational Safety and Health Management System (OSHMS) promotes a safe and healthy working environment by providing a framework for managers to consistently identify and eliminate health and safety risks, reduce the potential for accidents, aid legal compliance and improve overall performance.
There are several standards for OSHMS. In many of its locations, YKK has obtained certificates of compliance under the following major OSHMS standards:

1. OHSAS (Occupational Health and Safety Assessment Series) 18001

OHSAS 18001 is the internationally recognized assessment specification for OSHMS. It was developed by leading trade, international standards and certification groups. Main issues addressed by OHSAS 18001 are (a) hazard identification, (b) risk assessment, (c) risk control, (d) OHSAS management programs, (e) training awareness and competence and (f) performance measuring, monitoring and improvement.

2. JISHA OSHMS Standards

JISHA OSHMS standards were established by the Japan Industrial Safety and Health Association (JISHA) and conform to the guidelines for OSHMS of the Ministry of Health, Labor and Welfare of Japan. These standards are adapted for real life safety and health management situations as well as specific safety and health activities at Japanese companies.

YKK has acquired OHSAS 18001 certification in 27 locations and JISHA OSHMS certification in 6 locations as of July 2017.

Consumer Product Safety Improvement Act (CPSIA)

In the United States, YKK’s products meet the standards set by the Consumer Product Safety Improvement Act (CPSIA).

CPSIA was signed into law in August 2008, amending the provisions of the Consumer Product Safety Act. YKK does not make consumer products. However, its components are used in consumer products. Major requirements of CPSIA impacting our customers’ products and YKK’s commitments are described below:

1) Lead content in surface coating and substrates

Lead content in products manufactured by YKK, except TZN airtight/watertight zippers and zippers with lead crystals/rhinestones, does not exceed the lead content requirements of CPSIA, as confirmed through internal testing.

2) Phthalates

Products manufactured by YKK, except TZN airtight/watertight fasteners and Rail Seal Fasteners with PVC materials, do not exceed CPSIA phthalate limitations, as confirmed through internal testing.


Conflict Minerals

In addition to requiring that our suppliers comply with the above fair business practices, if our suppliers use 3TG metals (tin, tungsten, tantalum and gold – metals defined by U.S. law as conflict minerals that are mined in the Democratic Republic of the Congo, a country in which armed conflict and human rights abuses occur) in their products, we require that they provide us with satisfactory confirmation that they have conducted a “reasonable country of origin inquiry” to determine that their 3TG metals are not originally sourced from the DRC or adjoining countries or regions of conflict.

This requirement is derived from Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which requires that companies that make products that require 3TG metals to be produced or function must assess supply chains and publicly report on the source of these materials if they are sourced from regions of conflict in and around the DRC. YKK will not source 3TG containing raw materials from any supplier that is not able to provide us with satisfactory confirmation that they have conducted a “reasonable country of origin inquiry” to determine that their 3TG metals are not originally sourced from the DRC or adjoining countries.


What we Expect from our Suppliers

Fair business practices are the foundation of YKK’s business activities. Thus, we insist that our suppliers likewise engage in fair business practices.

In carrying out our business activities, the YKK Group is expected to undertake corporate social responsibility throughout its supply chain. To achieve this goal, we require the help of our trading partners and ask that they comply with the following fair business practices.

  • We require that our suppliers comply with applicable laws and regulations in their business activities as well as with social norms and implement fair and ethical business practices.
  • We require that our suppliers ensure that they do not use forced labor or child labor. We also require that they provide wages and other conditions of employment as well as maintain health and safety standards that comply with the laws of the countries and regions in which they do business.
  • We request that our suppliers promote the preservation of the global environment as well as engage in procurement activities that are in accordance with our Green Procurement Policy. This policy is based upon our corporate philosophy, the Cycle of Goodness, which states that an enterprise is an important member of society that must coexist with other elements of society and that the value of its existence will be recognized by the benefits it shares with society. The belief behind this is that nobody prospers without rendering benefit to others. We carry out business activities with the aim of ensuring mutual prosperity, and our belief is that innovative ideas and inventions results in business expansion for the YKK Group, which in turn brings prosperity to customers and trading partners and therefore benefits all of society.
  • We require that our suppliers also establish a quality assurance system for their products as well as ensure the quality and safety of products as required by the YKK Group.
  • We request that our suppliers build an appropriate information security system and manage their information resources appropriately.
