HS-4 · Heading
2621 — Slag and ash n.e.c. in chapter 26; including seaweed ash (kelp) and ash and residues from the incineration of municipal waste
Chapter 26: Ores, slag and ash
Plain-language overview
Use HS-4 2621 when importing slag and ash, including residues from municipal waste incineration. For example, if you're bringing in a shipment of ash generated from burning municipal solid waste, this code applies directly to your import.
When deciding between the two HS-6 lines under 2621, consider the source of the ash. HS-6 262110 is specific to ash and residues from municipal waste incineration, while HS-6 262190 covers other types of slag and ash, including seaweed ash, but excludes municipal waste residues.
If your shipment includes seaweed ash (kelp) or other non-municipal waste ashes, you should classify it under HS-6 262190. This distinction is crucial for compliance and duty assessment, as the two lines have different implications for import regulations.
