Xu Heyu, General Manager of a Hong Kong-invested porcelain development company in southern China, was always confident of the quality of his products. Now he is more than a little puzzled, facing a stockpile of more than 170,000 pots that no one wants. Xu"s company produces about 500,000 porcelain pots every year, mostly for export, which had been popular in the Japanese mar- ket until Japanese media reported in May, that file products might contain quantities of lead higher than the safety standards.
