Published Date: 2/26/2026

This means Chinese companies will still pay extra fees to keep prices fair and protect American businesses from harm. The decision took effect on February 23, 2026, so importers should be ready for these ongoing costs.

Products Covered by the Order
The Order covers all electrolytic manganese dioxide (MnO2) manufactured by an electrolysis process in powder, chip, or plate form and is classified at HTSUS 2820.10.00.00. Natural manganese dioxide (NMD) and chemical manganese dioxide (CMD) are explicitly excluded.
