The Quality Supervision Bureau of Guangzhou carried out the spot check of quality supervision on leather products, with a sampling of 80 batches of products, batch passing rate of 86%, within the range of the city. 　　

According to the news from the Quality Supervision Bureau of Guangzhou on Aug. 1st, in the second quarter of 2008, the result of the quality supervision spot check on the leather products conducted by the Quality Supervision Bureau of Guangzhou indicates that the batch pass rate is up to 86% in a total sample of 80 batches of the products produced in the city. Among them, the 11 batches of substandard products are all due to free formaldehyde exceeding index. 　　

One of the main reasons for the failure of passing the inspection is that part of the leather manufacturers use formaldehyde solution for the preservation of raw hides and skins. Without strictly controlled process, it can result in finished leather goods containing excess formaldehyde; another reason is that the dyes and adhesives used in the production process of leather may also bring toxic and hazardous substances into the products.
