Natural Graphite in Powder or Flakes

Crystalline flake graphite and graphite powder have become strategically critical inputs for lithium-ion battery anodes, making supply-chain origin a top concern for energy-storage manufacturers. The US schedule distinguishes crystalline flake graphite (excluding flake dust) at 2504101000 from other powder and flake forms at 2504105000, with classification hinging on particle morphology and processing state. Indonesia and Madagascar lead US import supply, with Canada and China also significant sources. Natural graphite in powder or flake form is subject to Section 301 tariffs when originating from China, adding a cost layer that has accelerated sourcing diversification.
