Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2621.90.00Same rate: 35%

If derived from municipal waste incineration

Chapter Note excludes municipal waste ash from 2620, directing to 2621 for incineration residues.

2613.10.00Lower: 11.8% vs 35%

If primarily copper content with minor arsenic

Roasted copper ores/blends shift to Chapter 26 mineral products if not qualifying as extraction slag.

3824.99Lower: 15% vs 35%

If chemically processed for direct compound use

Advanced chemical treatment may classify as prepared chemical binders rather than raw residues.
