High-Nickel Alloy Foundry Dust
Dust collected from foundries melting nickel alloys (>10% Ni by weight), suitable for nickel reclamation. Not from iron/steel making, thus under HTS 2620.99.30.00 for other metal-containing residues.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing over 10% chromium instead
Similar residues but chromium-dominant fall under separate subheading in 2620.99.
If remelted into nickel scrap form
Processed into usable nickel waste/scrap shifts to Chapter 75 nickel articles.
If from aluminum smelting with nickel
Alumina refinery residues classified in 2619, even with minor metals like nickel.

Import Tips & Compliance
• Include particle size and metal assay in import docs; reference statistical notes on quantity reporting
• Ensure not declared as finished alloy scrap (Chapter 72) to avoid duty shifts
• Partner with certified labs for pre-shipment testing to meet CBP residue classification
