Synthetic Yellow Iron Oxide Pigment
Synthetic yellow iron oxide (CI Pigment Yellow 42) is a goethite-based pigment with ≥70% Fe2O3 equivalent, engineered for construction materials and plastics coloration. Classified under HTS 2821.10.0040 as 'other' synthetic iron oxide pigments due to its artificial synthesis and high purity. It meets chapter requirements for chemically defined inorganic metal oxides.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for natural yellow earth colors like ochre
Naturally occurring mineral earth colors with ≥70% Fe2O3 are in 2530, excluding synthetic versions which stay in Chapter 28.
If dispersed in paint or varnish media
When iron oxide is incorporated into synthetic organic coloring matter or paints, it moves to Chapter 32 headings.
If as salts of inorganic acids rather than oxides
Ferric salts like ferric chloride derivatives may classify under complex salts if not meeting pure oxide criteria.

Import Tips & Compliance
• Confirm synthetic origin through production process documentation, as natural yellow ochres classify differently
• Test for heavy metal impurities to comply with REACH-like regulations and avoid dumping allegations
• Declare exact tint strength and oil absorption values on commercial invoice for accurate valuation
