U.S. imports of strontium carbonate (HS 283692) totaled $1.1M in June 2026, traded with 6 countries.
Importers of Strontium Carbonate paid $48K in duties in June 2026 — an effective duty rate of 4.3% on $1.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Strontium Carbonate imports of $1.1M in June 2026 ran 21% above the year-to-date monthly average of $917K.
Strontium carbonate is a niche industrial mineral used primarily in the manufacture of ferrite permanent magnets, color television faceplate glass (historically), and pyrotechnic red-flame compositions. Germany and Mexico are the leading US import sources under the single 10-digit line (2836920000). China is among the top five suppliers, and given that China dominates global strontite ore mining, importers sourcing from Chinese producers should assess Section 301 exposure. Demand patterns for this compound have shifted as CRT television production has declined, with ferrite magnet applications now driving the majority of consumption.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The decline of cathode-ray tube (CRT) television manufacturing — which required strontium carbonate in faceplate glass to block X-ray emissions — significantly reduced one major end use. Ferrite permanent magnet production for motors, speakers, and sensors has become the dominant application, and pyrotechnics remain a smaller but steady market.
Strontium carbonate from China may be subject to Section 301 tariffs. Importers should verify the current applicability of Section 301 lists and any product-specific exclusions against the 10-digit HTS code 2836920000 before finalizing sourcing decisions.
