Yes. Silver powder — including fine-particle grades used in conductive pastes for photovoltaic cells — falls under the semimanufactured or powder heading (68114). Importers sourcing silver paste precursors for solar manufacturing should confirm the exact particle size and purity specifications with their supplier, as these affect both classification and end-use documentation.

Standard commercial entry documents apply: a commercial invoice stating the silver content and purity, a packing list, and a bill of lading or airway bill. For large-value precious-metals shipments, CBP may require additional valuation documentation. If the silver originates from a country subject to trade-remedy measures, a certificate of origin is essential to establish the correct duty treatment.
