Uncompromising Product Quality Control

Policy

Uncompromising Product Quality Standards

JINS always strives for “Zero Compromise” to improve product quality. This is to enrich its customers’ lives through JINS products. JINS’s product quality standards conform not only to ISO standards (ISO 12870 and others) used by eyewear manufacturers around the world, and to the former JIS (Japanese Industrial Standards) in Japan, but also to JINS own internal standards and up to 20 inspections and visual inspections by humans in the final stage. JINS also uses Europe’s EN Standard that is widely used around the world for calculating blue-light blocking percentage. JINS takes pride in making world-class products that meet strict international standards.

Systems

Quality Control Systems

JINS has created the JINS Quality Control Systems (JQCS) to confirm that the quality assurance system conforms to and maintains the requirements for product realization and quality assurance.

・Scope of control
All products and daily operations handled by the quality assurance team are subject to control, and all operations are carried out in accordance with JQCS.

・Manager and subject of management of JQCS
The manager of JQCS is the quality assurance team leader, and all members of the quality assurance team work under the direction of the quality assurance team leader to structure the operations of JQCS.

・Division of roles in quality control
Based on the “flowchart of quality assurance operations” (control number: JQCS-1-02), the roles of the quality assurance team, related departments, and manufacturing factories from product planning to after-sales service are clearly defined. In addition, the roles of each member of the quality assurance team are clearly defined based on the “organization chart of the quality assurance team” (control number: JQCS-1-03).

・Quality policy
Based on the “Corporate Policy” and “Operations Department Policy,” the quality assurance team has established the “quality policy for the term.” Each member of the team carries out business activities using the PDCA method to achieve the team quality policy.

・Revision of JQCS
In order to optimize the operations of the quality assurance team, JQCS is periodically inspected and revised as necessary. All members of the quality assurance team are also obliged to promptly propose revisions to JQCS and optimize the contents of each document, rather than making personal improvements to JQCS when they recognize the need to improve operations or increase efficiency.

Initiatives for Quality Control

Quality Safety Confirmation by Third-Party Organizations

In order to further improve quality, JINS conducts quality safety confirmation by a third-party organization such as a global research organization for quality assurance. By conducting quality assurance by a third party, we are striving to improve the safety of our products and the reliability of our manufacturing process.

Pre-Shipment Inspection of Finished Products and Its Audit

JINS inspects the products manufactured in accordance with the JINS Quality Control Standards at the factory before shipment, and the Quality Assurance Department determines whether the required quality is met, thereby guaranteeing the quality assurance of the products. In addition to appointing a manager responsible for inspection from among the members of the quality assurance team to supervise incoming inspection operations, we have established a management system to ensure that outsourced inspectors fully understand JQCS and JQRS before engaging in outsourced incoming inspections.

Emergency Measures

Measures in Case of a Voluntary Product Recall

When a product defect is discovered, the quality assurance team compiles the number of inquiries from customers, the number of registered defects at stores, and the number of inquiries from various organizations, and calculates the expected frequency of occurrence and the expected degree of harm, which are quantitative evaluation criteria. The Risk Committee then approves the validity of the quantitative evaluation criteria, and the final decision is made according to the following procedures A through C.

A) Decision by the officer in charge
The decision made by the Risk Committee shall be approved and submitted to the Management Committee after considering factors to be considered in management decisions on recalls.

B) Second opinions from third-party experts (lawyers, academics, consumer groups, etc.) and third-party opinions on the appropriateness of JINS’s “implementation criteria for product recalls,” “quantitative evaluation criteria for product recalls,” etc., the appropriateness of the evaluation of the case at hand, and the appropriateness of the decision on the merits and content of the recall shall be obtained.

C) Management’s final decision
The final decision shall be made based on the above second opinion of a third party.
