o-Anisidine
o-Anisidine (2-methoxyaniline) is a chemically defined organic compound with an amino group and an ether oxygen function on a benzene ring. It falls under this tariff item as an oxygen-function amino-compound, per Chapter 29 note (a). It is used in dye and pharmaceutical synthesis.
o-Anisidine Hydrochloride
The hydrochloride salt of o-Anisidine is classified with the parent organic compound under Chapter 29 note 5(C)(1), which states inorganic salts of organic compounds are classified in the heading appropriate to the organic compound. The salt retains the oxygen-function amino-compound classification under this tariff item. It is used in analytical chemistry and dye coupling.
o-Anisidine Technical Grade 98%
Technical grade o-Anisidine at 98% purity qualifies as a chemically defined compound with impurities under Chapter 29 note (a). The impurities do not affect its classification as an oxygen-function amino-compound under this tariff item. It is used in bulk for industrial dye production.
o-Anisidine with Emetic Additive
o-Anisidine with a trace emetic additive is permitted under Chapter 29 note (g), which allows added substances for safety identification, provided they do not render the product suitable for a specific use. The product retains its classification as an oxygen-function amino-compound under this tariff item. It is used in industrial handling where poison prevention is required.
p-Anisidine
p-Anisidine (4-methoxyaniline) is a chemically defined organic compound with an amino group and a methoxy ether oxygen function. It falls under this tariff item as an oxygen-function amino-compound, per Chapter 29 note (a). It is primarily used in azo dye manufacturing and as a corrosion inhibitor.
p-Anisidine in Ethanol Solution 20%
A 20% solution of p-Anisidine in ethanol is classified under this tariff item per Chapter 29 note (e), which allows solutions in other solvents when the solvent is a normal and necessary method of putting up for safety or transport. The solution retains the classification of the oxygen-function amino-compound. It is used in laboratory reagent formulations.
p-Anisidine Stabilized with Antioxidant
p-Anisidine with an added antioxidant stabilizer is permitted under Chapter 29 note (f), which allows stabilizers necessary for preservation or transport. The product retains its classification as an oxygen-function amino-compound under this tariff item. It is used in rubber antioxidant testing, specifically for aniline value determination.
p-Phenetidine
p-Phenetidine (4-ethoxyaniline) is a chemically defined organic compound with an amino group and an ethoxy ether oxygen function. It falls under this tariff item as an oxygen-function amino-compound, per Chapter 29 note (a). It is used in pharmaceutical synthesis, such as phenacetin, and as a dye intermediate.
p-Phenetidine Acetate Ester
The acetate ester of p-Phenetidine is classified with the acid-function compound that occurs last in numerical order per Chapter 29 note 5(A). Since the base (p-Phenetidine) is classified in this heading and the ester is formed with an acid from a later sub-chapter, the ester is classified with the acid-function compound, but the base retains its classification under this tariff item as the principal component. It is a pharmaceutical intermediate.
p-Phenetidine for Dye Synthesis
High-purity p-Phenetidine designated for azo dye production is a chemically defined organic compound with an amino group and an ethoxy ether oxygen function. It falls under this tariff item as an oxygen-function amino-compound, per Chapter 29 note (a). It is not yet a colouring matter, as it is an intermediate, and is not excluded under Chapter 32.
