Recently, the leather safety boots exported to Spain by a shoe company in Yuyao, Ningbo, were notified by the European Union that the hexavalent chromium of the products exceeded the standard, and the excessive material involved upper leather. After investigation, the main reason is that the leather quality provided by the upstream leather supplier of the enterprise has problems, and the enterprise has not carried out the incoming inspection when purchasing
according to statistics, since the beginning of this year, the European Union’s rapid warning system for non food products (RApex) has issued a total of 11 notifications of leather products, including 10 notifications of excessive hexavalent chromium content in leather materials, 7 notifications of shoes and 3 notifications of gloves. The continuous occurrence of such incidents has sounded an alarm for leather export enterprises
hexavalent chromium is an extremely toxic substance for ingestion and inhalation, which can invade human body through digestion, respiratory tract, skin and mucous membrane. Skin contact can cause allergy. Once sensitized, the concentration of 3 mg / kg is enough to cause allergic reaction; More likely to cause genetic defects, inhalation may cause cancer, there is a lasting risk to the environment< 1t is reported that as early as December 2011, the European Commission for Standardization (CEN) passed the new version of safety shoes standard eniso20345:2011, which stipulates that the content of hexavalent chromium is not more than 3mg / kg, which has come into effect in June 2012. On March 26, 2014, the European Commission issued an official gazette to amend annex 17 of reach regulation and extend the hexavalent chromium restriction order for leather products, which requires that the hexavalent chromium content in leather products directly in contact with human skin shall not exceed 3mg / kg. For products containing leather parts, the content of hexavalent chromium in leather parts contacting with human body shall not exceed 3mg / kg. Those exceeding the limit shall not be put on the market, and the affected products include shoes, clothing, hats, wristbands and toys. The regulation will be formally implemented on May 1, 2015 to strengthen the control requirements of hexavalent chromium in leather and other products in EU will have a great impact on leather product manufacturers such as shoes and clothing. Therefore, the inspection and quarantine department suggests that relevant enterprises: first, they must clarify the limit requirements of hexavalent chromium in EU and establish the concept of green product production; The second is to strengthen the quality acceptance of raw and auxiliary materials, and test the content of hexavalent chromium in leather raw materials. Third, strictly monitor the storage and transportation environment of raw materials and finished products to avoid trivalent chromium being oxidized into hexavalent chromium.
