9902.14.91 - Clad strips of silver, further worked than semimanufactured, each containing 54 percent or more but not over 56 percent by weight of silver; having three layers with one layer containing 87 percent or more but not over 89 percent by weight of silver and 11 percent or more but not over 3 percent of tin, a second layer containing 99.9 percent or more by weight of silver, and a third layer containing 14.5 percent or more but not over 15.5 percent by weight of silver, 79 percent or more but not over 81 percent of copper and 4.8 percent or more but not over 5.2 percent of phosphorus; measuring 15.65 mm in width and 0.95 mm in thickness, presented in coils (provided for in subheading 7115.90.40)

This HTS category, 9902.14.91, is highly specific, covering clad strips of silver that have undergone further processing beyond a semimanufactured state. The core characteristic is their silver content, which must be between 54% and 56% by weight. These strips are distinguished by a complex three-layer construction. The first layer contains 87% to 89% silver and 3% to 11% tin. The second layer is pure silver (99.9% or more), and the third layer comprises 14.5% to 15.5% silver, 79% to 81% copper, and 4.8% to 5.2% phosphorus. Further defining criteria include precise dimensions of 15.65 mm in width and 0.95 mm in thickness, and their presentation in coils.

Given that this is a leaf node within Chapter 99, it does not have subcategories. Its parent context, Section XXII and Chapter 99, signifies that this classification falls under temporary legislation, modifications proclaimed pursuant to trade agreements, or additional import restrictions. This contrasts significantly with the general commodity classifications found in other sibling categories at the root level (e.g., live animals in Chapter 01), highlighting its specialized nature as a controlled or restricted import item rather than a standard trade good. The detailed material composition and physical attributes are the primary classification determinants, overriding general classifications of precious metals or metal articles.
