The threshold applies on a per-dozen-pieces-or-parts basis to each distinct article type in the shipment. Importers must calculate the per-dozen value for each style or SKU separately rather than averaging across the entire shipment. If a single style's per-dozen value straddles the threshold, CBP will apply the classification corresponding to the actual per-dozen transaction value for that style. Accurate style-level pricing on the commercial invoice and packing list is therefore critical.

Silver jewelry must be marked with its country of origin in a conspicuous location that is legible and permanent, in accordance with 19 U.S.C. § 1304 and CBP regulations. For small items where direct marking is impractical, CBP may allow marking on a tag or container, but the importer must demonstrate that direct marking is not feasible. Pieces assembled or substantially transformed in a country other than where the silver was refined will take the origin of the country of last substantial transformation.
