Subheadings
Products classified under Tariff item 2811.19.00
33% Hydrobromic Acid in Acetic Acid
A 33% hydrobromic acid solution in glacial acetic acid is a chemically defined inorganic acid, but the solvent is not water. Under Chapter Note 1(c), it qualifies if the acetic acid is a normal and necessary method of putting up for safety or transport and does not render the product suitable for specific use.
48% Hydrobromic Acid Solution
A 48% aqueous solution of hydrogen bromide gas (HBr) is a chemically defined inorganic acid in water. It is classified under this tariff item as an other inorganic acid of a non-metal, per Chapter Note 1(b).
Anhydrous Hydrobromic Acid Gas Cylinder
Anhydrous HBr gas in steel cylinders is a chemically defined inorganic acid in gaseous form. It is classified under this tariff item as an other inorganic acid of a non-metal, as it is not excluded by Chapter Notes.
Arsenic Acid Anhydride Powder
Anhydrous arsenic acid powder, also known as arsenic pentoxide when dehydrated, is a chemically defined inorganic compound used in electronics etching. It is classified as an inorganic acid of a non-metal under Chapter 28, meeting the criteria of Note 1(a) to Chapter 28.
Arsenic Acid for Flame Retardant Synthesis
Purified arsenic acid used for synthesizing flame retardants in plastics is a chemically defined inorganic acid. It is not a finished flame retardant product, so it falls under this tariff item as an other inorganic acid of a non-metal.
Arsenic Acid H3AsO4 (99% Purity)
Arsenic acid (H3AsO4) at 99% purity is a colorless to white crystalline solid used in chemical synthesis and as a reagent. It is a separate chemically defined compound of a non-metal, qualifying under this tariff item.
Arsenic Pentoxide Solution (50% Aqueous)
An aqueous solution of arsenic pentoxide (As2O5), equivalent to arsenic acid, is used in glass manufacturing and wood preservation. As a solution of a chemically defined inorganic compound in water, it falls under this tariff item per Chapter Note 1(b).
Battery-Grade Arsenic Acid Electrolyte
Ultra-pure arsenic acid for specialty battery electrolytes is a chemically defined inorganic acid. It is not a finished electrolyte, so it is classified under this tariff item as an other inorganic acid.
Fuming Hydrobromic Acid 55%
Fuming 55% hydrobromic acid that emits HBr vapors is a chemically defined inorganic acid. It is classified under this tariff item as an other inorganic acid, provided it is in aqueous solution.
High-Purity Arsenic Acid for Glass Production
High-purity H3AsO4 used as a fining agent in optical glass manufacturing is a chemically defined inorganic acid. It is not excluded by Chapter Note 3(d) as it is not a luminophore, so it falls under this tariff item.
Hydrobromic Acid 47-52% Semiconductor Grade
Ultra-pure hydrobromic acid (47-52% assay) for semiconductor manufacturing is a chemically defined inorganic acid in aqueous solution. It is classified under this tariff item as an other inorganic acid.
Industrial Arsenic Acid 75% Solution
A 75% aqueous industrial arsenic acid solution for wood treatment and textile dyeing processes is a chemically defined inorganic acid in water. It qualifies under this tariff item as an other inorganic acid of a non-metal.
Laboratory Reagent Arsenic Acid (ACS Grade)
ACS-grade arsenic acid for analytical chemistry and lab research meets high purity standards as a chemically defined inorganic acid. It is not an organo-inorganic compound, so it falls under this tariff item.
Meta-Arsenic Acid Flakes
Meta-arsenic acid (HAsO2) flakes, a polymeric form used in pharmaceutical intermediates, is a chemically defined inorganic acid. It is classified under this tariff item as an other inorganic acid of a non-metal.
Technical Grade Arsenic Acid Crystals
Technical grade arsenic acid (H3AsO4) crystals for industrial applications like pesticide intermediates and flame retardants is a chemically defined inorganic acid. It qualifies under this tariff item as an other inorganic acid.
