Products classified under HTS 1518.00.40.00
Epoxidized Soybean Oil
Epoxidized soybean oil is produced by chemically modifying soybean oil through epoxidation, converting double bonds into epoxide groups for enhanced stability. It falls under HTS 1518.00.40.00 as a chemically modified vegetable oil fraction used primarily as a plasticizer and stabilizer in PVC production, not for human consumption.
Blown Linseed Oil
Blown linseed oil is linseed oil that has been oxidized by blowing air through it at elevated temperatures, increasing viscosity for use in paints and varnishes. Classified under HTS 1518.00.40.00 as an oxidized (chemically modified) vegetable oil unsuitable for food use.
Polymerized Castor Oil
Polymerized castor oil undergoes heat treatment in vacuum to form high-viscosity polymers used in lubricants and coatings. It qualifies for HTS 1518.00.40.00 as a heat-polymerized vegetable oil fraction, inedible for industrial applications.
Sulfurized Mineral-Lard Oil Blend
This inedible preparation combines sulfurized lard oil with mineral oil for extreme pressure metalworking lubricants. HTS 1518.00.40.00 covers such mixtures of chemically modified animal/vegetable fats not elsewhere specified.
Dehydrated Tallow Fatty Acids
Dehydrated tallow fatty acids result from water removal and distillation of animal tallow, used in soap noodles and rubber processing. Classified in HTS 1518.00.40.00 as chemically modified (dehydrated) animal fat fractions.
Oxidized Fish Oil
Oxidized fish oil is chemically modified by controlled oxidation to raise peroxide value for leather tanning and printing inks. HTS 1518.00.40.00 includes such inedible modified marine oils.
Heat-Polymerized Coconut Oil
Heat-polymerized coconut oil is vacuum-heated to dimerize fatty acids, creating viscous products for cosmetics and polishes. Falls under HTS 1518.00.40.00 as polymerized by heat in vacuum vegetable oil.
Sulfurized Sperm Whale Oil Substitute
Synthetic blend mimicking sulfurized sperm whale oil for marine gear lubricants, using vegetable triglycerides. HTS 1518.00.40.00 covers sulfurized inedible fat/oil mixtures.
Boiled Tung Oil
Boiled tung oil is polymerized by heating with metallic driers, used in traditional wood finishing. Classified under HTS 1518.00.40.00 as heat-polymerized vegetable oil.
Microbial Oil Fatty Acid Esters
Fatty acid esters from fermentation-derived microbial oils, chemically modified for biolubricants. HTS 1518.00.40.00 includes modified microbial fats explicitly.
