At the SITC level, all nickel powders and flakes — regardless of particle size or shape — fall within 68323. However, at the HTS 10-digit level, distinctions may exist between alloy and non-alloy compositions, so importers should confirm the applicable tariff line based on alloy content rather than physical form. Particle size specifications are commercially critical but do not by themselves change the heading.

Nickel powder used in battery cathode precursors (NMC, NCA chemistries) is subject to growing scrutiny under US critical-minerals policy, and buyers should assess whether their supply chain may be affected by sourcing restrictions or incentive programs tied to domestic content requirements. Traceability documentation from mine to powder is increasingly requested by downstream battery manufacturers and may be required for compliance with applicable incentive frameworks.
