Working with chapter 28

Chapter 28 of the Harmonized System covers inorganic chemicals, rare-earth compounds. It is organised into 50 four-digit headings and 180 six-digit subheadings, and national tariffs extend those to eight or ten digits. Because the six-digit level is shared worldwide, it is the right level for comparing trade between countries, while the national digits matter for duty rates and licensing.

On EximTradeIntel each subheading opens a table of actual shipments, 2019-2026, so you can see how goods in this chapter are described on real declarations, what they are worth per unit, which ports they move through and which companies are trading them. That makes the chapter useful for classification checks, for pricing a tender, and for building buyer or supplier lists inside a narrow product family. Searching is free, and only exports use credits. See the full chapter index for neighbouring categories.
