Products classified under Tariff item 2909.50.00.00
4-Ethylguaiacol 99%+ USP Grade
Ultra-pure 4-Ethylguaiacol meeting USP standards for pharmaceutical intermediate use. High purity does not change classification; it remains a separate chemically defined ether-phenol under tariff item 2909.50.00.
2909.50.004-Ethylguaiacol Bulk Drum Pack
4-Ethylguaiacol packaged in 200L steel drums for industrial users. The packaging does not alter the chemical identity of the compound, which remains a separate chemically defined ether-phenol under tariff item 2909.50.00.
2909.50.004-Ethylguaiacol Flavor Intermediate
High-purity 4-Ethylguaiacol designated as an intermediate for clove-like flavor synthesis in the food industry. Despite its intended use, it remains a separate chemically defined ether-phenol compound, classifiable under tariff item 2909.50.00.
2909.50.004-Ethylguaiacol Perfume Base Material
4-Ethylguaiacol serving as a spicy-woody base note in fine fragrance formulations. As a pure, chemically defined ether-phenol, it falls under tariff item 2909.50.00, regardless of its use in perfumery.
2909.50.004-Ethylguaiacol Pharmaceutical Precursor
4-Ethylguaiacol for synthesis of pharmaceutical intermediates. It is a chemically defined ether-phenol compound, classifiable under tariff item 2909.50.00, even though it is intended for pharmaceutical research.
2909.50.004-Ethylguaiacol Pure Compound
4-Ethylguaiacol as a pure, chemically defined ether-phenol compound with molecular formula C9H12O2. It features a guaiacol structure with an ethyl substituent at the 4-position, falling under tariff item 2909.50.00.
2909.50.004-Ethylguaiacol Research Grade
Small quantity 4-Ethylguaiacol packaged for laboratory research (<1L). The packaging size does not affect classification; it remains a pure, chemically defined ether-phenol under tariff item 2909.50.00.
2909.50.004-Ethylguaiacol Stabilized for Transport
4-Ethylguaiacol with added polymerization inhibitor (BHT <0.1%) for safe transport, allowed under Chapter 29 note (f). The stabilizer is necessary for preservation or transport and does not render the product for specific use, so it remains under tariff item 2909.50.00.
2909.50.004-Ethylguaiacol Technical Grade
Technical grade 4-Ethylguaiacol with 95-98% purity and minor impurities. It still qualifies as a separate chemically defined compound per Chapter 29 note (a), classifiable under tariff item 2909.50.00.
2909.50.004-Ethylguaiacol with Anti-Dusting Agent
4-Ethylguaiacol in fine powder form treated with a minimal anti-dusting agent (<0.5%) for safe handling. The anti-dusting agent does not render the product particularly suitable for a specific use, so it remains a separate chemically defined ether-phenol under Chapter 29.
2909.50.004-Ethylguaiacol with Emetic Additive
4-Ethylguaiacol with a trace emetic additive for safety identification, permitted by Chapter 29 note (g). The emetic does not make the product particularly suitable for a specific use, so it remains classified as an ether-phenol under tariff item 2909.50.00.
2909.50.004-Methylguaiacol (Creosol)
4-Methylguaiacol (creosol), a guaiacol derivative obtained from guaiacum resin or wood creosote, used in organic synthesis and as a disinfectant. It is a chemically defined ether-phenol, classifiable under tariff item 2909.50.00.
2909.50.00Guaiacol (Methoxyphenol)
Guaiacol (2-methoxyphenol), a naturally occurring organic compound found in wood smoke and creosote, used as a precursor in pharmaceutical synthesis and as an expectorant. It is a chemically defined ether-phenol, classifiable under tariff item 2909.50.00.
2909.50.00Isoeugenol (2-Methoxy-4-(1-propenyl)phenol)
Isoeugenol (2-methoxy-4-(1-propenyl)phenol), an unsaturated guaiacol derivative used in perfumery and as a vanillin precursor. Its ether-phenol structure maintains classification under tariff item 2909.50.00.
2909.50.00Methylguaiacol (2-Methoxy-4-methylphenol)
Methylguaiacol (2-methoxy-4-methylphenol), a positional isomer derivative of guaiacol used in flavor chemistry and as a synthetic intermediate. It qualifies as a chemically defined ether-phenol under tariff item 2909.50.00.
