8001.20.00.10 - Containing, by weight, 5 percent or less of lead

This HTS classification, 8001.20.00.10, specifically identifies unwrought tin in alloy form that contains a very low concentration of lead, defined as 5 percent or less by weight. These are essentially tin alloys where lead is present only as a minor impurity or intentionally added in minimal quantities, and the dominant metal is tin. Examples include certain specialized solders or master alloys where high purity tin is the primary constituent, and lead content is strictly controlled.

This category is distinguished from its siblings based on the precise percentage of lead by weight. 8001.20.00.50 covers tin alloys with a higher lead content, ranging from more than 5 percent up to 25 percent, while 8001.20.00.90 encompasses those with over 25 percent lead. Therefore, the key differentiator for 8001.20.00.10 is its adherence to the upper limit of 5 percent lead by weight.

As this is a leaf node in the HTS, there are no further subcategories. Classification at this level is determined solely by the composition, specifically the percentage of lead by weight within the unwrought tin alloy. Importers and exporters must ensure accurate quantitative analysis of the material to correctly assign it to this specific tariff line.
