Frequently asked questions

Buy genuine at official points

The branch and dealers are on the map.

Where to buy
Where is KORTEX made?

All current products are made at a partner plant in South Korea; the label says MADE IN KOREA.

Company
What does the QR code on the label open?

KORTEX's official Instagram page (@kortex_oil). If the QR leads to another site, the product is suspicious.

Is there a check code under the cap?

Not yet. Checking by a unique code is planned. Until then, rely on the label marks and an official seller.

What is the batch number for?

It is printed on every can and shows which batch the product comes from. Do not buy a can without a number or with a rubbed-off one.

What if I bought a fake?

Do not use it. Send photos of the label, the batch number and where you bought it on Telegram; we will check and tell you what to do next.
