Silver Nitrate

Silver nitrate is a foundational inorganic silver compound with broad commercial use in photographic chemicals, medical antimicrobial preparations, mirror silvering, and analytical chemistry reagents. Classified entirely within a single 10-digit line (2843210000), it is distinguished from other silver compounds — which fall under heading 284329 — by its nitrate anion and its distinct reactivity profile. The United Kingdom and Poland are the leading US import sources, with China, Canada, and South Korea also supplying the market. Importers should note that silver nitrate used in pharmaceutical or medical device applications may be subject to FDA oversight depending on its intended end use.
