Quality is Central to the YKK’s Group’s Management and Business Activities

Ever since its founding, quality has been central to the YKK Group’s management, and all of its business activities therefore revolve around the assurance of quality. Maintaining stable and constant quality has become one of the key concerns for many global manufacturers, and in order to support these companies, YKK has established YKK Fastening Standards (YFS) to provide products of the same quality level, wherever and whenever they are manufactured. Each YKK production site conducts various quality tests and reports the results to our headquarters in Japan on a regular basis in order to maintain and assure a consistent quality level.

YKK Quality Management

YKK Worldwide Network

Many manufacturers are now producing in multiple locations around the world as the globalization of manufacturing continues to expand.

YKK Group – 73 countries/regions, 111 companies (Mar. 2018)

YKK also abides by laws and regulations around the world concerning safety, environmental, and social issues to meet customer requests from various regions. We have been reinforcing our quality management system, and in some cases, have developed specific products to meet certain laws and regulations.

Laws and Regulations

YKK has always made safety and quality our top priorities and has thus been investing its resources to ensure that products manufactured by YKK meet all applicable standards. Below are descriptions of some of those key laws.

United States

Consumer Products Safety Improvement Act of 2008 (CPSIA)

The CPSIA was signed into law in August 2008, amending the provisions of the Consumer Product Safety Act. The main objectives of the CPSIA are to (a) strengthen consumer product safety standards, (b) increase safety requirements for children’s products and (c) revitalize the Consumer Product Safety Commission. YKK does not make consumer products. However, its components are used in consumer products. Major requirements of the 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 PROSEAL® airtight/watertight zippers and zippers with lead crystals/rhinestones, does not exceed the lead content requirements of the CPSIA, as confirmed through internal testing.

2) Phthalates

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





Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) is the European Community Regulation of the safe use of chemicals and deals with registration, evaluation, authorization and restriction of chemical substances. Major requirements of the law that can potentially be related to fastening products are listed below:

1) SVHC (Substances of Very High Concern)

None of the 174 substances listed in the candidate list of SVHC (as of July 2017) are found in YKK’s major products in a concentration of more than 0.1% (w/w), except Rail Seal Fasteners with PVC materials, PROSEAL® airtight/watertight zippers, and flame retardant zippers with Conex® and Nomex® tape.

2) European Nickel Restriction (part of Annex XVII)

All YKK products indicated as “N-ANTI” meet the above mentioned nickel restriction: Metal zippers using nickel material, such as 3YN, 3MN, 4MN, 5RN, 5RNM etc., metal finishes using nickel material, such as NP, NS, HP etc.
