Vanadium Ash from Boiler Combustion
Ash residue from industrial boiler combustion of heavy fuel oils, bearing vanadium oxides and minor metals, unprocessed. Fits HTS 2620.99.7520 as other vanadium bearing residues not advanced in condition or value, suitable for metal extraction. Excludes municipal waste incineration ash.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from municipal waste incineration
Ash/residues from household waste burning are specifically excluded from 2620 and classified separately.
If from iron or steel manufacture
Heading 2620 excludes slag/ash from iron/steel production, directing to 2620.19 instead.
If chemically processed for compounds
If advanced beyond residue state for chemical manufacture, it may classify as chemical preparations.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Submit detailed chemical analysis reports showing vanadium predominance and low Cu/Pb/Zn levels
• Ensure documentation distinguishes from iron/steel slag to prevent Chapter 72 misclassification
• Label residues clearly as 'not advanced in value' to comply with subheading criteria
