U.S. imports of high-purity bismuth and articles (over 99.99%) (HS 810610) totaled $2.4M in July 2026, traded with 5 countries.
High-Purity Bismuth and Articles (Over 99.99%) imports of $2.4M in July 2026 ran 198% above the year-to-date monthly average of $822K.
Last updated: July 2026 dataPurity above 99.99% by weight is the defining commercial specification here, positioning this bismuth grade for pharmaceutical synthesis, semiconductor dopants, and specialty low-melting alloys where trace impurities are unacceptable. South Korea and Japan are the leading US import sources under this heading, reflecting advanced refining infrastructure in Northeast Asia. Importers should note that bismuth's role as a lead substitute in certain applications has driven demand growth, and the single 10-digit line (8106100000) covers both the metal and articles made from it at this purity level.

The US schedule splits bismuth at the 99.99% purity level: material at or above this threshold classifies under 810610, while lower-purity bismuth and scrap fall under 810690. Purity is verified by the supplier's certified chemical analysis (typically ICP-OES or fire assay), which should accompany the commercial invoice. CBP may request laboratory testing if documentation is insufficient.
The primary end uses for 99.99%+ bismuth include pharmaceutical active ingredients (bismuth subsalicylate and related compounds), semiconductor manufacturing as a dopant, and specialty fusible alloys used in fire-suppression systems and precision casting. These applications require tight impurity controls that lower-grade bismuth cannot meet, which is why the purity distinction carries commercial and regulatory significance.
