All such compounds enter under 2843290100, making precise product identification in commercial documentation essential for accurate classification. The United Kingdom and Japan are the leading US suppliers under this heading.

Silver nitrate is explicitly excluded and classified under 284321. Additionally, silver in colloidal form falls under 284310. Amalgams of silver are covered by 284390. Importers dealing in mixed or complex silver-containing materials should verify the primary chemical identity to confirm the correct heading.
CBP expects a certificate of analysis identifying the compound by chemical name and CAS number, the silver content by weight, and the manufacturing process. For novel or proprietary silver compounds, a binding ruling request may be advisable to lock in the correct 10-digit classification before commercial shipments begin.
