HTS US: 2621.XX.XXXX
Description
Heading 2621 encompasses a variety of non-metallic by-products primarily consisting of slags, ashes, and residues. This includes ash derived from seaweed (commonly referred to as kelp ash) as well as ash and residues generated through the incineration of municipal waste. These materials are generally used in industrial applications such as construction, agriculture, or waste management.
The heading is divided into two main categories:
- Ash and residues from the incineration of municipal waste: These are the leftover solid materials after municipal garbage has been burned at waste treatment facilities. They often contain various minerals and non-combustible components.
- Other slags and ashes (including seaweed ash): This includes ashes not derived from municipal waste, such as those produced by burning seaweed (kelp), as well as other miscellaneous slags and ashes.

Detailed Breakdown of Subheadings
The 4-digit HS heading 2621 is broken down into specific 6-digit and 10-digit US HTS codes that distinguish between ash and residues from municipal waste incineration and other types of ash and slag including seaweed ash.
| HTS Code | Description | Examples & Notes |
|---|---|---|
| 2621.10.00.00 | Ash and residues from the incineration of municipal waste | Includes bottom ash, fly ash and other solid residues left after burning municipal solid waste; used in landfill cover, cement production, or stabilization. |
| 2621.90.00.00 | Other | Includes seaweed (kelp) ash and other slags and ashes not resulting from municipal waste incineration. |
What is NOT Classified Here?
Items excluded from this heading include:
- Metallic slags specifically derived from metal smelting processes are classified under other specific headings.
- Coal ash and related residues are classified separately under Chapter 27.
- Other types of waste residues not resulting from municipal waste incineration or seaweed burning.
Notes
- Environmental Regulations: Disposal and use of ashes and residues from municipal waste incineration are subject to strict environmental regulations in the United States to prevent contamination and ensure safe reuse.
- Industrial Uses: Seaweed ash is commonly used as a fertilizer or soil conditioner due to its mineral content, while municipal incineration ash can be used in construction materials.
- Import Restrictions: Importers should check local regulations regarding the import and use of such ashes and residues due to potential hazardous components.
