Important Notice on Korean Market

WARNING: Some Korean companies import inferior and non-KC certified products into Korea using our KC certificates.

It has come to our attention that some Korean companies are importing inferior and non-KC certified products into Korea using our KC certificates. RHY, the leading manufacturer and exporter of power tool batteries in China, wishes to address this issue promptly.


Recently, we received a notification from the KTC organization regarding the cancellation of one of our KC certificates due to a product failing market sampling inspection tests. Upon investigation, we confirmed that the non-compliant product was not manufactured or supplied by RHY.

After a thorough inquiry, it was discovered that a Korean company misused our KC number to import substandard products from other Chinese manufacturers that lacked KC certification. These products were subjected to Korean market inspections and were found to be non-compliant, posing significant risks due to the absence of essential safety features.

About KC certification

The KC certificate is a prerequisite for electronic products to enter the Korean market. It is one of the most stringent certification standards in the world, and products certified by KC usually use better materials and have superior quality.

Unfortunately, some unscrupulous Korean companies use our KC certificate to import cheaper and inferior products that are not KC certified. These products lack the basic protection circuit module (PCM) to protect the battery from overcharge, over-discharge, overload, overtemperature, short circuit, etc., which has great risks of fire and explosion.
