As we all know, the United States has very strict requirements for masks exported from China. Not long ago, the FDA cancelled the export qualifications of more than 60 companies, which was a hot topic. Recently, Canada followed suit and issued an official announcement, warning about the quality and safety of some imported masks and other epidemic prevention materials, and also announced 60 unqualified companies.
Canada announces 60 unqualified companies Recently, the Canadian government released a list of unqualified companies. The reason for the failure is that the filtration level of their masks is lower than 95%. Dozens of Chinese mask manufacturers have been included in this "blacklist"! The list released by Canada has also added a column that makes related mask companies worried - the recall of unqualified masks! Subsequently, the Ministry of Health has contacted importers and distributors, asking them to immediately stop sales and notify consumers, and change the labels to indicate that these masks may not meet the standards for use by frontline medical staff and can only be used when other filtration levels do not require 95%. The Ministry of Health’s announcement did not specify the number of masks in this batch, but the official website further pointed out that the masks involved failed to pass the National Practical Testing Laboratory (NPPTL) of the National Occupational Safety and Health (NIOSH) of the U.S. Centers for Disease Control and Prevention (CDC). CDC official website announces 77 unqualified businesses Yesterday (May 18), the official website of the US CDC listed a batch of masks and manufacturers that have been tested. Original article released by CDC According to the test results given in the report, if measured according to Canada's standard of "the minimum filtration rate cannot be lower than 95%", the masks produced by 86 of the 148 Chinese mask companies tested were unqualified. In other words, the pass rate of these masks from China is as low as 41%! Green: "The minimum filtration rate is not less than 95%" Gray: "Minimum filtration rate is less than 95%" PS: Manufacturers indicated by an asterisk (*) have informed NIOSH that the products evaluated are not manufactured by them and should be considered counterfeit and misuse of their company names. Previously, the Canadian Ministry of Health had approved the use of KN95 masks for medical purposes against the new coronavirus, and said that the standards of N95 and KN95 in terms of filtration, effect and material were similar. However, recent CDC tests showed that some KN95 masks did not meet the standards. A related report by the Associated Press pointed out that a batch of counterfeit masks attempted to imitate medical-grade N95 masks produced by Chinese manufacturers and had been distributed to front-line medical staff in some hospitals in the United States. The testing certification number TC84A-4329 granted by the CDC to a Shanghai manufacturer (Shanghai Dasheng Co.) was misappropriated by other Chinese mask manufacturers, who then sold unqualified products to the U.S. market. One obvious difference is that the counterfeit masks have ear loops, while the qualified masks have straps that tie to the head for a tighter fit. All masks with ear loops are considered fake. N95 masks that pass the test After testing, the US Centers for Disease Control and Prevention (CDC) has revoked the licenses of a number of Chinese manufacturers to sell in the United States, some of which have licenses from the Canadian Ministry of Health. According to reports, of the 11 masks tested by the CDC, only 4 met the standards. The stop-use order is not limited to the 7 masks that do not meet the standards, but also includes a batch of masks that have not yet been tested. Of the 80 Chinese mask manufacturers that were first approved by the United States, only 14 of them can still be used in the United States. It is worth mentioning that the quality of the Chinese masks tested varies greatly. N95 and KN95 masks should filter at least 95% of all particles with a diameter of 0.3 microns. The test showed that all 10 KN95 samples from a manufacturer in Guangdong passed, and 4 of them achieved a 100% filtration rate. All 10 samples from another company failed, with the highest filtration rate being only 76%. Among the 10 samples from another company, 5 had a filtration rate of 98% and 99%, and the other 5 had a filtration rate of only 24% to 26%. (Source : Foreign Shipping ) |
