Products classified under HTS 2933.49.10.00
Ethoxyquin Antioxidant Powder
Pure ethoxyquin (1,2-Dihydro-6-ethoxy-2,2,4-trimethylquinoline) in powder form used primarily as a synthetic antioxidant to prevent oxidation in animal feeds and pet foods. This chemically defined heterocyclic compound with a quinoline ring system falls under HTS 2933.49.10.00 as it matches the specific legal description. It is imported as a separate organic compound for industrial formulation into feed preservatives.
Ethoxyquin 66% Liquid Premix
Ethoxyquin diluted in propylene glycol to 66% concentration, supplied as a liquid premix for easy incorporation into poultry and swine feeds as an oxidation inhibitor. Classified under HTS 2933.49.10.00 per Chapter 29 note (e) as solvent dissolution is necessary for safe transport without rendering it suitable for specific use. The core active remains the chemically defined quinoline compound.
Ethoxyquin Technical Grade Flakes
Technical grade ethoxyquin in flake form (90% minimum purity) for manufacturing animal feed antioxidants and rubber stabilizers. This specific quinoline derivative is explicitly named in HTS 2933.49.10.00 as a separate chemically defined organic compound. Flake form facilitates industrial handling while maintaining chemical identity.
Ethoxyquin with Stabilizer Beads
Ethoxyquin beads containing added anticaking stabilizer (per Chapter 29 note f) for preservation during transport in animal nutrition applications. Remains classified under HTS 2933.49.10.00 as the stabilizer is necessary for the pure compound's stability. Used in pet food and aquaculture feeds.
Ethoxyquin Aquaculture Preservative Solution
33% ethoxyquin solution in vegetable oil for fish feed preservation, preventing fat oxidation in salmon and trout formulations. Chapter 29 note (e) allows solvent use for safety; classified HTS 2933.49.10.00 as the quinoline compound remains principal. Widely used in seafood processing plants.
Ethoxyquin Pet Food Stabilizer Granules
Granulated ethoxyquin (with anti-dusting agent per note g) for dry pet food manufacturing to extend shelf life. Specific quinoline structure qualifies for HTS 2933.49.10.00 despite minor safety additions. Used by major pet food brands like Purina and Mars.
High-Purity Ethoxyquin USP Grade
Pharmaceutical-grade ethoxyquin (>98% purity) meeting USP standards for use as reference standard and research chemical. As a chemically pure quinoline compound, classified HTS 2933.49.10.00 regardless of high purity. Used in analytical labs and veterinary research.
Ethoxyquin Rubber Antioxidant Pellets
Ethoxyquin pellets for synthetic rubber compounding, providing thermal oxidation protection during tire manufacturing. Despite rubber end-use, remains HTS 2933.49.10.00 as separate defined organic compound imported for chemical reaction. Used by Goodyear, Michelin tire producers.
Ethoxyquin Feed Grade 95% Crystals
95% purity ethoxyquin crystals for direct addition to animal feed premixes, meeting EU and FDA maximum residue limits. Explicitly HTS 2933.49.10.00 as the named quinoline compound in crystalline form. Primary use prevents vitamin destruction in feeds.
