Nippon Light Metal Holdings Company, Ltd. announced today that Nikkei Extrusions Company, Ltd.,a subsidiary, received notice from the Japan Quality Assurance Organization (JQA) concerning
temporary suspension of its JIS certification effective June 30, 2021 regarding JIS-marked products
manufactured at its Okayama Plant, on the grounds that the standards specified in the Ministerial
Ordinance on Certification of Conformity to Japanese Industrial Standards relating to mineral andindustrial products and their processing technologies are not satisfied.
The Nippon Light Metal Group sincerely apologizes for the great inconvenience and concern caused
to customers and other stakeholders from this disposition handed down by the JQA for inadequate
quality control systems, which follows the disposition concerning the Nippon Light Metal Nagoya
Plant.
We reported the improper conduct that led to the temporary suspension of JIS certification to theSpecial Investigation Committee established on June 9, 2021, which is made up of three attorneys andtwo outside directors of the company.
We take the disposition imposed by the JQA very seriously and will conduct an extensive review ofGroup quality control systems, make every effort to restore trust, and work to have the temporary
suspension lifted and regain trust as soon as possible.
Details
1. Background to the Temporary Suspension
Nikkei Extrusions acquired JIS certification of its Okayama Plant, but it also manufactures non-JISmarked products (“Non-JIS-Marked Products”). Following the update of the computer-based
production control system on December 1, 2020, improper conduct occurred whereby identification
tags displaying JIS marks were attached to some Non-JIS-Marked Products at the time of shipment
and the products were shipped in that state. This was not noticed, and the shipments continued until
March 11, 2021.
Nikkei Extrusions reported this improper conduct to JQA on May 18, 2021 and was subject to a
provisional certification maintenance inspection. This inspection determined that there wereinadequacies in the quality control system including improper conduct, and the company was subject
to a temporary suspension of its JIS certification effective June 30, 2021. Since May 19, 2021, Nikkei
Extrusions has not displayed JIS marks on some products produced at the Okayama Plant that had
displayed the mark until then (JIS H 4040, JIS H 4080, and JIS H 4100).
2. Details of the Disposition
Details of disposition:
Temporary suspension of JIS certification
Reasons for disposition: (1) Products were shipped without displaying the labeling mattersspecified in the JIS standards;(2) Products were shipped with labeling of quality classifications not
specified by the JIS standards;(3) Products outside the scope of certification were shipped with JIS
