U.S. imports of alloy steel powders (HS 720521) totaled $7.1M in April 2026, traded with 15 countries.
Last updated: April 2026 dataAlloy steel powders are a critical input for metal injection molding, additive manufacturing (3D printing), and powder metallurgy components used in automotive and aerospace applications — sectors that demand tight compositional tolerances. The single US tariff line (7205210000) covers all alloy steel powder grades, meaning the alloying elements (chromium, nickel, molybdenum, etc.) that define performance must be documented in mill certificates but do not subdivide the HTS line. Sweden and Germany are leading suppliers alongside Canada, reflecting those countries' specialized atomization and high-alloy steel expertise. Section 232 tariffs apply to this product.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP may request a mill certificate or chemical analysis report confirming the presence and weight percentages of alloying elements (e.g., chromium, nickel, molybdenum). Alloy steel is defined under HTS Chapter 72 notes by minimum thresholds for specific elements; if those thresholds are not met, the product classifies as nonalloy steel powder under 7205.29.
Both countries host major producers with decades of investment in gas and water atomization technology capable of producing powders with the narrow particle-size distributions and low oxygen content required for additive manufacturing and high-performance sintered parts. This technical specialization creates a supply concentration that importers should factor into sourcing risk assessments.
