Subheadings
Products classified under Tariff item 2921.41
99.5% Pure Aniline Drums
Industrial aniline at 99.5% purity, a separate chemically defined aromatic monoamine (C6H5NH2). It is the base compound for dyes, pigments, and polyurethane precursors, and meets the chapter's criteria for a chemically defined organic compound.
2921.41.00Aniline 99.8% Low Impurity
Ultra-low impurity aniline at 99.8% purity, a chemically defined aromatic monoamine. Its high purity makes it suitable for sensitive pharmaceutical and agrochemical synthesis, but it remains the same base compound under this tariff item.
2921.41.00Aniline Base 99.95% Spectro Grade
Spectroscopy-grade aniline at 99.95% purity for analytical and research use. It is a separate chemically defined compound, and its high purity does not change its classification as aniline.
2921.41.00Aniline (CAS 62-53-3)
Aniline (CAS 62-53-3), a primary aromatic amine with the formula C6H5NH2. It is a fundamental building block for dyes, pharmaceuticals, and rubber chemicals, and is a chemically defined compound under this tariff item.
2921.41.00Aniline for Dye Intermediates
High-purity aniline for azo dye production, classified as the base aromatic monoamine. It is not a finished dye, so it falls under this tariff item rather than dye headings.
2921.41.00Aniline Technical Grade 99.9%
Technical grade aniline at 99.9% purity, the industrial standard for MDI production and antioxidants. It is a chemically defined aromatic monoamine, meeting the chapter's requirements.
2921.41.00Aniline USP Grade
Aniline meeting USP pharmacopeia standards, a high-purity aromatic monoamine for drug intermediate synthesis. It is a chemically defined compound, and its pharmaceutical grade does not alter classification.
2921.41.00Aniline with Emetic Additive
Aniline with a trace emetic additive for safety identification, permitted under chapter note (g). The additive does not make the product suitable for a specific use, so it remains classified as aniline.
2921.41.00Aniline with Stabilizer (0.1% diphenylamine)
Aniline stabilized with 0.1% diphenylamine to prevent oxidation, allowed under chapter note (f) as necessary for preservation. The stabilizer does not alter the product's classification as aniline.
2921.41.00Bulk Aniline Railcar Import
Aniline imported in bulk railcars for industrial use, a pure chemically defined compound. The mode of transport does not affect classification, and it remains aniline under this tariff item.
2921.41.00High-Purity Aniline for MDI Production
Aniline refined for MDI synthesis, classified as pure aniline before the reaction. It is a chemically defined aromatic monoamine, and its intended use does not change classification.
2921.41.00Molten Aniline (heated transport)
Aniline shipped in molten form at elevated temperatures to prevent solidification. It remains a pure aromatic monoamine, and the physical state does not affect classification.
2921.41.00Pharma-Grade Aniline BP
Aniline complying with British Pharmacopoeia standards, a pure aromatic monoamine for pharmaceutical synthesis. It is a chemically defined compound, and its pharmacopeia grade does not change classification.
2921.41.00Redistilled Aniline
Redistilled aniline purified via fractional distillation to remove impurities. It remains a separate chemically defined aromatic monoamine, and the purification process does not alter classification.
2921.41.00Stabilized Aniline in ISO Tanks
Aniline with minimal stabilizer transported in ISO tanks, qualifying under chapter note (f) as a preserved aromatic monoamine. It is for large-scale polyurethane production.
