Abstract: An identification example of imported lead alloy was presented in thispaper. The physical and chemical characteristics, polluting properties and the generation of the sample were analyzed, and then the properties of the sample were identified according to a great deal of experimental data. The results showedthat the sample of imported lead alloy might be smelted products from a wasted lead-acid battery, not metal. The lead metal had been concentrated to a certainextent, butlarge amounts of impurities were still contained in it, which might cause environmental pollution during the production process. According to the Guideline of Solid Waste Identification, the sample of imported lead alloy was identified finally to be solid waste. This conclusion provided basic information for the customs management in China.
