Importers of Silicon Carbide (Crude and Processed) paid $132K in duties in July 2026 — an effective duty rate of 1.6% on $8.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Silicon Carbide (Crude and Processed) imports of $19.8M in July 2026 ran 71% above the year-to-date monthly average of $11.6M.
Last updated: July 2026 dataSilicon carbide is a critical abrasive and refractory material widely used in grinding wheels, cutting tools, semiconductor substrates, and high-temperature industrial applications. The US tariff schedule distinguishes between crude silicon carbide (2849201000) and grain, ground, or refined forms (2849202000), with the processing grade determining end-use suitability. China dominates US supply by a wide margin, followed by Norway and Taiwan, making this heading a recurring focus of Section 301 trade-remedy exposure for importers sourcing from Chinese producers. Buyers should verify grit size, purity specifications, and origin documentation carefully, as crude and refined grades carry different classification and pricing implications.

HTS 2849201000 covers crude silicon carbide as produced directly from the furnace, while 2849202000 covers material that has been further processed into grain, ground, or refined forms. The distinction matters for duty calculation and end-use classification, particularly when the same shipment contains mixed particle sizes.
Yes. Silicon carbide imported from China is subject to Section 301 tariffs. Importers should confirm the applicable tariff action and any product-specific exclusions with a licensed customs broker before entry, as rates and exclusion lists have changed over time.
