Products classified under Tariff item 2917.11.00
Ammonium Oxalate
Ammonium oxalate, also known as diammonium oxalate, is a salt of oxalic acid used in textile dyeing and as an analytical reagent. As an inorganic salt of an organic acid, it is classified under tariff item 2917.11.00 per Chapter 29 Note 5(C)(1), which directs salts to the heading of the parent organic compound.
Calcium Oxalate
Calcium oxalate monohydrate is an insoluble white powder used in ceramics and as an analytical standard. As a salt of oxalic acid, it is classified under tariff item 2917.11.00 per Chapter 29 Note 5(C)(1), which keeps inorganic salts of organic acids with the parent acid heading.
Dibutyl Oxalate
Dibutyl oxalate is an ester of oxalic acid used as a plasticizer intermediate and solvent. Per Chapter 29 Note 5(A), esters of acid-function organic compounds are classified with the compound that occurs last in numerical order; since oxalic acid (2917) is the acid component, the ester falls under 2917.11.00.
Diethyl Oxalate
Diethyl oxalate is the ethyl ester of oxalic acid, used in pharmaceutical synthesis and dye manufacturing. As an ester of oxalic acid, it is classified under tariff item 2917.11.00 per Chapter 29 Note 5(A), which assigns esters to the heading of the acid component when it occurs last in numerical order.
Dimethyl Oxalate
Dimethyl oxalate is the dimethyl ester of oxalic acid, used as a solvent and chemical intermediate. It falls under tariff item 2917.11.00 as an ester of oxalic acid, per Chapter 29 Note 5(A) which classifies esters with the acid component's heading.
Dipotassium Oxalate
Dipotassium oxalate is a potassium salt of oxalic acid used in laboratory analysis and as a precipitating agent. As an inorganic salt of an organic acid, it is classified under tariff item 2917.11.00 per Chapter 29 Note 5(C)(1), which keeps salts with the parent acid heading.
Disodium Oxalate
Disodium oxalate is the anhydrous sodium salt of oxalic acid, used in water treatment and as a calibration standard. It is classified under tariff item 2917.11.00 per Chapter 29 Note 5(C)(1), which directs inorganic salts of organic acids to the heading of the parent acid.
Ethyl Methyl Oxalate
Ethyl methyl oxalate is a mixed ester of oxalic acid used as a specialty solvent and intermediate. As an ester of oxalic acid, it falls under tariff item 2917.11.00 per Chapter 29 Note 5(A), which classifies esters with the acid component's heading when it occurs last in numerical order.
Ferric Ammonium Oxalate
Ferric ammonium oxalate is a coordination compound of iron and oxalate, used in blueprint photography and iron analysis. Per Chapter 29 Note 5(C)(3), coordination compounds are classified by cleaving metal bonds; the resulting organic fragments are oxalate, so it falls under tariff item 2917.11.00.
Oxalic Acid 10% Solution
Oxalic acid 10% solution is an aqueous solution of oxalic acid used for rust removal and wood bleaching. Per Chapter 29 Note 1(d), products of chemically defined organic compounds dissolved in water are covered by the chapter, so it falls under tariff item 2917.11.00.
Oxalic Acid Dihydrate
Oxalic acid dihydrate is the crystalline form of oxalic acid, used in industrial cleaning and metal polishing. As a separate chemically defined acyclic polycarboxylic acid, it falls under tariff item 2917.11.00 per Chapter 29 Note 1(a).
Oxalic Acid Technical Grade
Technical grade oxalic acid dihydrate with 97-99% purity is used for industrial cleaning and metal treatment. Despite impurities, it remains a chemically defined organic compound per Chapter 29 Note 1(a), which allows for impurities, so it falls under tariff item 2917.11.00.
Oxalic Acid with Anti-Caking Agent
Oxalic acid with anti-caking agent is oxalic acid dihydrate mixed with less than 0.5% silicon dioxide to ensure free-flowing powder. Per Chapter 29 Note 1(f), products with added stabilizers necessary for preservation or transport are covered, so it falls under tariff item 2917.11.00.
Potassium Binoxalate
Potassium binoxalate, also known as potassium hydrogen oxalate, is an acid salt of oxalic acid used in photography and metal finishing. As an acid salt of an organic acid, it is classified under tariff item 2917.11.00 per Chapter 29 Note 5(C)(1), which keeps salts with the parent acid heading.
Sodium Oxalate
Sodium oxalate is the disodium salt of oxalic acid, used in analytical chemistry and textile processing. As an inorganic salt of an organic acid, it is classified under tariff item 2917.11.00 per Chapter 29 Note 5(C)(1), which directs salts to the heading of the parent acid.
