Subheadings
Products classified under HTS 2821.10.00
Ferric Hydroxide Precipitate
Precipitated ferric hydroxide (Fe(OH)3) used in water treatment, pharmaceuticals, and as pigment intermediate. Classified under 2821.10.00 for iron hydroxides with >70% iron as Fe2O3 equivalent. High purity for industrial purification processes.
Synthetic Yellow Iron Oxide for Concrete
Synthetic yellow iron oxide pigment optimized for coloring concrete blocks and pavers. Falls under 2821.10.00 as iron oxide >70% Fe2O3, alkali-resistant for cement mixes. Standard in construction coloration.
Granular Black Iron Oxide for Ferrites
Granular Fe3O4 iron oxide precursor for manufacturing soft ferrites in transformers. HTS 2821.10.00 for pure iron oxides used in electronics. Calcined to precise stoichiometry.
Synthetic Red Iron Oxide Pigment
A high-purity synthetic iron oxide (Fe2O3) pigment used in paints, coatings, and plastics for red coloration. It falls under HTS 2821.10.00 as it is a chemically defined iron oxide containing over 70% combined iron evaluated as Fe2O3. This subheading covers both synthetic and natural iron oxides and hydroxides used primarily as colorants.
Yellow Iron Oxide Hydroxide (Goethite)
Synthetic yellow iron oxide hydroxide (FeOOH), known as goethite, used for pigmentation in construction materials and cosmetics. Classified in 2821.10.00 due to its high iron content (>70% as Fe2O3 equivalent) and status as an iron hydroxide. Essential for tinting cements and primers.
Black Iron Oxide (Magnetite) Powder
Micronized black iron oxide (Fe3O4, magnetite) powder for magnetic inks, ferrites, and industrial pigments. HTS 2821.10.00 applies as a chemically defined iron oxide with >70% combined iron as Fe2O3. Widely used in electronics and ceramics.
Natural Red Ochre Iron Oxide
Naturally occurring red ochre, a calcined iron oxide earth color with ≥70% Fe2O3, used in artist paints and traditional pigments. Fits 2821.10.00 as an earth color meeting the iron content threshold from Chapter 28 notes. Preferred for historical restoration work.
Micaceous Iron Oxide
Flaky micaceous iron oxide (MIO) for anti-corrosive primers and protective coatings. HTS 2821.10.00 covers this lamellar iron oxide variant with ≥70% Fe2O3. Provides barrier protection in marine paints.
