HS Code 2621Slag and ash n.e.c. in chapter 26; including seaweed ash (kelp) and ash and residues from the incineration of municipal waste
2 six-digit codes · Heading 21 of 21 in Chapter 26 · World Customs Organization Harmonized System
HS code 2621 is the catch-all heading for slag and ash that no other heading in Chapter 26 covers. It includes ash from burnt municipal waste and seaweed ash, also called kelp ash.
The WCO writes heading 2621 as a residual bucket: goods of Chapter 26that answer to “Slag and ash n.e.c. in chapter 26; including seaweed ash (kelp) and ash and residues from the incineration of municipal waste” and that no more specific heading in the chapter already claims. It still carries 2 six-digit codes, 262110 through 262190, so “other” is not the end of the classification here. The heading is number 21 of 21 in Chapter 26, Ores, slag and ash, which runs to 37 six-digit codes in all.
What HS code 2621 covers
Think of 2621 as the "other" drawer for slag and ash. Most of its headings name one ore, such as copper or tin. Headings near the end deal with slag and ash. If a waste material of this kind does not fit those specific headings, it lands here.
The label "n.e.c." means "not elsewhere classified". In plain words, it means "not named anywhere else in the chapter". The heading is part of the Harmonized System, the shared code list that customs offices around the world use. In India the same six digits are used as the HSN code 2621.
Two kinds of goods are named on purpose. One is ash and residues left after burning municipal waste. Both are mineral waste products or by-products rather than ores, which is why they sit in the slag and ash part of the chapter.
HS 262110 vs 262190: which code to use
Heading 2621 splits into two six-digit codes. The split is simple. One code is for ash from burnt municipal waste. The other code is for everything else.
Check the origin of the material first. Ask whether it came from burning municipal waste. If yes, it goes under the first code. If no, check whether it is any other slag or ash from Chapter 26, such as kelp ash.
- Goods people call incinerator bottom ash from a waste plant are the kind of thing this code is meant for.
- It includes seaweed ash (kelp) but leaves out ash and residues from municipal waste incineration.
How 2621 differs from other slag headings in Chapter 26
Four headings in the chapter deal with slag and ash. They are easy to mix up. The key question is where the material came from and what it contains.
HS 2618 is for granulated slag, also called slag sand, from making iron or steel. HS 2619 is for other slag and dross from iron or steel making, plus scalings and other waste from that work. So both of these are tied to the iron and steel industry.
It is about waste with metal content.
HS 2621 is the leftover heading. It catches slag and ash that is not iron or steel waste and is not metal-bearing residue, plus the two named cases of municipal waste ash and seaweed ash. If you are unsure, work through 2618, 2619 and 2620 first. If none fits, 2621 is likely right.
Duty depends on the national tariff line under 262110 or 262190, and each country sets its own. Use the HS code classifier to check a product before you ship.
