Products classified under HTS 2909.50.40.50
Guaiacol
Guaiacol is a naturally occurring organic compound with the formula C6H4(OH)OCH3, classified as an ether-phenol used primarily as an odoriferous compound due to its smoky, phenolic aroma. It falls under HTS 2909.50.4050 as an other odoriferous ether-phenol compound not specifically excluded by chapter notes. Commonly extracted from wood creosote, it's employed in flavorings and fragrances.
Anethole
Anethole (trans-anethole) is a phenylpropanoid ether-phenol compound responsible for the licorice flavor in anise and fennel, chemically defined as C6H4(OCH3)(CH=CHCH3). It qualifies under HTS 2909.50.4050 as an other odoriferous ether-phenol derivative used in flavorings. Synthetic or natural forms are imported for food and fragrance industries.
Eugenol
Eugenol is an allyl chain-substituted guaiacol (ether-phenol) with formula C10H12O2, prized for its clove-like odor and flavor profile. Classified under HTS 2909.50.4050 as an other odoriferous ether-phenol compound per Chapter 29 definitions. Widely imported from clove oil distillation for perfumery and dental applications.
Vanillin
Vanillin is a phenolic aldehyde with methoxy ether substitution (4-hydroxy-3-methoxybenzaldehyde), valued for vanilla flavor and odor. Technically an ether-phenol derivative under HTS 2909.50.4050 when imported as odoriferous compound, though aldehyde function noted. Synthetic vanillin dominates global imports.
Ethyl Vanillin
Ethyl vanillin is a synthetic ether-phenol analog of vanillin with ethoxy substitution, offering intensified vanilla odor and flavor. Classified under HTS 2909.50.4050 as other odoriferous ether-phenol compound consistent with Chapter 29 definitions. Preferred in confectionery for cost-effective vanilla profile.
Methyl Eugenol
Methyl eugenol is an allylbenzene ether compound with phenolic methoxy group, used for spicy-floral odor in perfumery. Falls under HTS 2909.50.4050 as chemically defined odoriferous ether-phenol derivative per Chapter 29. Subject to regulatory scrutiny due to safety concerns.
Piperonal
Piperonal (heliotropin) is a benzodioxole ether-phenol derivative with intense floral-vanilla odor used in lily-of-the-valley perfumes. Classifies under HTS 2909.50.4050 as odoriferous ether-phenol per Chapter 29 heterocyclic provisions. Key synthetic fragrance intermediate.
Safrole
Safrole is a phenylpropanoid ether compound with methylenedioxy phenol functionality, historically used for root beer/sassafras flavor. Now strictly regulated, imports under HTS 2909.50.4050 as odoriferous ether-phenol for permitted industrial uses. DEA-watchlisted substance.
Isoeugenol
Isoeugenol, an isomer of eugenol, features a propenyl side chain on the ether-phenol core, used for its rose-like, spicy odor in carnation perfumes. Falls under HTS 2909.50.4050 as other odoriferous ether-phenol per Chapter 29 scope for chemically defined compounds. Imported as fragrance intermediate.
Chavicol
Chavicol (4-allylphenol) is a simple ether-phenol with allyl substitution, contributing herbal-spicy odor in basil and betel flavors. Imported under HTS 2909.50.4050 as other odoriferous ether-phenol compound. Used in natural fragrance compositions.
