9902.14.89 - Silver in semimanufactured form, containing by weight 87 to 89 percent of silver, 11 to 13 percent of tin and 0.1 to 0.7 percent of copper oxide, presented in the form of strip and certified by the importer as suitable for use in electrical contact systems intended for the manufacture of switches and relays (provided for in subheading 7106.92.50)

This HTS category, 9902.14.89, specifically covers silver in a semimanufactured form, characterized by its precise composition of 87% to 89% silver, 11% to 13% tin, and 0.1% to 0.7% copper oxide. The physical form is limited to strip. Crucially, this material must be certified by the importer as being suitable for use in electrical contact systems destined for the manufacture of switches and relays. This certification is a key differentiator, indicating a specific industrial application and quality standard.

While the broader HTS system classifies a vast array of goods, this particular category exists within Chapter 99, which is reserved for temporary legislation, trade agreement modifications, and special import restrictions. Therefore, it is distinct from the general commodity classifications found in earlier chapters. Its placement under Chapter 99 signifies that its coverage and tariff treatment are subject to specific, time-limited provisions rather than standard, long-term tariff structures.

As this is a leaf node within the HTS, there are no further subcategories to detail. The classification is highly specific and does not break down into more granular levels. The unique combination of material composition, physical form, and certified end-use for electrical contact systems in switches and relays defines the entirety of what falls under HTS code 9902.14.89.
