U.S. imports of high-purity silicon (99.99% or greater) (HS 280461) totaled $6.1M in April 2026, traded with 12 countries.
At 99.99% purity or above, silicon qualifies as electronic-grade or semiconductor-grade material, the foundational substrate for integrated circuits, solar wafers, and photovoltaic cells — making 2804610000 one of the most strategically watched lines in the chemicals schedule. Malaysia leads US import supply, followed by Germany and Taiwan, reflecting the geographic concentration of polysilicon and wafer production capacity in Southeast and East Asia. Importers should monitor Section 301 exposure for shipments originating from China, as supply-chain tracing through intermediate processing countries is a recurring compliance concern.

The dividing line is 99.99% silicon content by weight. Material at or above that threshold falls under 280461 (tariff line 2804610000) and is generally electronic or solar grade. Material below 99.99% falls under 280469, which is further split between 99–99.99% purity and below 99% purity, the latter being metallurgical-grade silicon used in aluminum alloys and chemical synthesis.
Malaysia is the top supplier, followed by Germany and Taiwan. Japan and Laos also appear among notable sources. Given the global polysilicon supply chain's complexity, importers often need to document the country of origin carefully to assess Section 301 tariff applicability.
