HS Code 2914.23 – Ketones; cyclanic, cyclenic or cycloterpenic, without other oxygen function, ionones and methylionones

HS code 2914.23 is the 6-digit subheading for ketones, cyclanic, cyclenic or cycloterpenic, without other oxygen function, ionones and methylionones. It is used for alpha-Ionone, beta-Ionone, gamma-Ionone, methylionone and iso-Methylionone.

What HS 2914.23 covers

Ionones and methylionones are highly valued fragrance and flavor chemicals, crucial for the perfumery, cosmetics, and food industries. These compounds are known for their violet-like and woody scents, and their role in creating complex aroma profiles. International trade involves specialized fine chemical and fragrance houses exporting these high-purity ingredients to manufacturers of perfumes, soaps, detergents, and food products globally. Importers are typically formulators and producers in the consumer goods sector. The trade often involves smaller, high-value quantities, with emphasis on purity, specific isomer composition, and sensory characteristics. Key considerations include compliance with food and cosmetic safety regulations (e.g., IFRA standards, FDA regulations), as well as intellectual property surrounding specific fragrance formulations. The market is driven by consumer trends in personal care and food & beverage sectors.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
