Certification test for needle marks

Because of poor management in the production process, there are often broken needles (including sewing needles, pins, etc.) in quilted products such as garments.

In the 80s of last century, there were frequent incidents of consumer injuries caused by broken needles in clothing. This prompted the Japanese government to enact laws and regulations to protect consumer rights and interests in order to strengthen the control of residual needles.

According to the laws of Japan, if the products produced or sold are broken, the producers and sellers will be severely punished. If consumers are injured, they will be compensated.

In order to avoid economic losses caused by broken needles, Japanese clothing importers not only require manufacturers to inspect needles before they are manufactured, but also set up inspection factories for needle checking.

For the products qualified by the needle, hang or attach the needle marks.
