Products classified under HTS 1518.00.20.00
Boiled Linseed Oil
Boiled linseed oil is produced by heating and oxidizing linseed oil to accelerate drying for use as a wood finish and protective coating. It falls under HTS 1518.00.20.00 as a chemically modified vegetable oil from linseed (flaxseed), specifically boiled or oxidized, excluding those in heading 1516.
Polymerized Linseed Oil
Polymerized linseed oil undergoes heat treatment in vacuum or inert gas to increase viscosity for use in alkyd resins and industrial coatings. Classified in HTS 1518.00.20.00 for chemically modified linseed oil fractions, polymerized by heat as specified in the heading.
Blown Linseed Oil
Blown linseed oil is air-oxidized under pressure to create a thick, tacky product used in putties, sealants, and printing inks. It is included in HTS 1518.00.20.00 as linseed oil 'otherwise chemically modified,' specifically blown.
Oxidized Linseed Oil Stand Oil
Stand oil is linseed oil heated and oxidized to form a high-viscosity binder for artists' paints and varnishes. HTS 1518.00.20.00 covers this as oxidized linseed oil, chemically modified for industrial non-food applications.
Sulfurized Linseed Oil
Sulfurized linseed oil is chemically treated with sulfur to enhance extreme pressure properties for industrial lubricants and metalworking fluids. It qualifies under HTS 1518.00.20.00 as sulfurized linseed oil, a specified chemical modification.
Dehydrated Linseed Oil
Dehydrated linseed oil has water and impurities removed for faster-drying paints and enamels. Classified in HTS 1518.00.20.00 as chemically modified (dehydrated) linseed oil for industrial use.
Heat-Polymerized Linseed Oil for Alkyds
This linseed oil is polymerized by heat in inert gas for short-oil alkyd resin production in paints. HTS 1518.00.20.00 applies to linseed-specific chemically modified oils via heat polymerization.
Industrial Linseed Oil Putty Base
Thickened linseed oil base (blown/oxidized) for manufacturing glazing putties and caulks. Falls under HTS 1518.00.20.00 as modified linseed oil, prior to putty formulation.
