HS Code for Seaweed ash

Seaweed ash, also known as kelp ash, is classified under HS code 2621.90. This classification falls within Chapter 26, which covers ores, slag, and ash. Heading 2621 is a broad category for \"Other slag and ash, including seaweed ash (kelp).\" The classification is based on the product being a residue of the incineration of vegetable matter. Seaweed ash is produced by burning dried seaweed to recover mineral salts, particularly iodine and potash. Unlike raw or dried seaweed, which is an organic plant product, seaweed ash is an inorganic residue consisting of the mineral components of the plant. Under the General Rules of Interpretation, the specific mention of seaweed ash in the Explanatory Notes for 2621 confirms its placement here. It is treated as a mineral-rich industrial raw material rather than a botanical product.

Products Included

• Incinerated kelp residue

Common Misclassification

Seaweed ash is often confused with raw or dried seaweed, which is classified under 1212.21 (for human consumption) or 1212.29 (for other uses). The key distinction is the process of incineration; if the seaweed has not been burned to ash, it cannot be in Chapter 26. It is also sometimes misclassified as a fertilizer under 3104 (potassic fertilizers). While seaweed ash contains potash, it is considered a raw material residue rather than a manufactured fertilizer unless it has been further processed or chemically treated.
