2621
Other slag and ash, including seaweed ash (kelp); ash and residues from the incineration of municipal waste
Analysis
Heading 2621 of the Harmonized Tariff Schedule covers other slag and ash, including seaweed ash (kelp); ash and residues from the incineration of municipal waste. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 2 ten-digit statistical suffixes below them.
Every one of its 2 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.
The largest subheadings are 2621.10 (unnamed, 1 line) and 2621.90 (unnamed, 1 line).
Its median rate of duty-free sits at the 49th percentile of the headings in chapter 26.
The heading text decides whether a product belongs here at all (General Rule of Interpretation 1); the subheadings and lines below it only apply once that is settled. Section and chapter notes can override the heading wording, so read them for borderline goods.
