With the spread of the pneumonia epidemic, many dealers asked A to "plan to sell masks." Masks that are not certified by KF are not important. Because the shape of the mask is not much different from the KF certified mask. A company said that it bought a customized mask of A at a price of 312 won each and signed a contract of 2 million, but other companies that recently exported masks to mainland China said that they would increase the price at a price of 900 won each. 3 times. In the end, A decided to bear liquidated damages and transfer the goods to a higher price enterprise.

Regarding the worry about the production of masks that he not passed the quality certification, the company said that "Although they he not obtained the KF certification of masks issued by the Korean Food and Drug Safety Agency, there is no problem in selling them as industrial products." "As far as I know, they We want to sell these products to mainland China, but sales are the responsibility of distributors, and we don’t care about it."

The Korean Food and Drug Safety Agency will check the "leakage rate" of this mask, the "inspiratory resistance" for measuring the breathing volume of the mask, and the strength of the rope, and issue KF certification. If a mask cannot be certified as a health mask, it cannot be sold as a medical product, but can only be sold as an "industrial product" for cold protection and other purposes.

However, with the spread of the pneumonia epidemic, masks are out of stock, and "industrial" masks that he not been certified by KF are disguised as health masks for sale. Because of the same appearance, it is difficult to distinguish with the naked eye. Some companies say on packaging or advertisements: ‘We he obtained KF certification’ to sell fake health masks.

The reporter saw on the streets of Myeongdong in Seoul on the 12th that some stall owners disguised industrial masks as "KF94" masks. After hearing the news of a shortage of masks in the Myeongdong pharmacy frequented by foreign tourists, they found uncertified masks for sale. They raised the price of industrial masks to 2,000 won and sold them. Some companies also openly claimed that they distribute "KF94" masks, which can be said to be a "partial trick" used to induce consumers to buy cheap industrial masks in private.
