Where these two actually differ

  • We flag Iron leaching into food and Rust and surface degradation on the Coconut Oil and not on the Coconut Oil.
  • We flag Thermal degradation and oxidation products, Heavy metals (arsenic, cadmium, lead) in plant material, Pesticide residues and Rancidity and mold if stored improperly on the Coconut Oil and not on the Coconut Oil.
  • The Coconut Oil is cast iron, bare or seasoned with coconut oil where the Coconut Oil is Refined coconut oil, edible liquid, which is most of the difference in these two grades.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
