HS Code 2821
Iron Oxides, Hydroxides, and Earth Colours
HS code 2821 covers synthetic iron oxides and hydroxides, plus earth colours with over 70% iron content, used as pigments for construction and paints.
HS Code 2821 — Iron Oxides, Hydroxides, and Earth Colours
This code covers synthetic iron oxides and hydroxides used as pigments and in magnetic recording media. Crucially, it also includes 'earth colours' (like ochre or sienna) provided they contain 70% or more iron by weight. They are the most common inorganic pigments for construction, coatings, and plastics.
What's included
- Ferric oxide
- Ferrous hydroxide
- Synthetic ochre
- Iron oxide red/yellow/black
What's excluded
- Natural iron ores → use
2601(Unprocessed ores belong in Chapter 26.) - Earth colours with < 70% iron → use
2530(Lower iron content earths are treated as mineral substances.)
Common examples
- Iron oxide red 130
- Yellow iron oxide pigment for pavers
- Micaceous iron oxide
- Synthetic ferric hydroxide
Frequently asked questions
What determines if an earth colour is in 2530 or 2821?
The threshold is 70% iron content (calculated as Fe2O3). Below this, it remains a mineral (2530); at or above, it is a chemical pigment (2821).
Trade & shipping notes
- Typical duty range: 0% - 3%
- Documentation: Test reports verifying iron content as Fe2O3 percentage are essential for earth colours.
- Typical shipping mode: FCL
- Top exporters: China, Germany, Italy
- Top importers: United States, India, United Kingdom

Key takeaway
Always verify the iron percentage for earth-based pigments to ensure correct chapter classification.
