Import Tips & Compliance

Provide battery precursor end-use statement for potential duty exemptions under clean energy programs

Ultra-high purity requires third-party assay certificates to prevent 3824 downgrade

Avoid classifying NMC precursors as mixtures (3824) by confirming single-compound status
