HS Code for Methylionones

Methylionones are classified under HS code 2914.23. These substances are organic chemical compounds that fall under the category of cyclanic, cyclenic, or cycloterpenic ketones without other oxygen functions. Methylionones are vital components in the fragrance and flavor industry, known for their violet-like and woody aromas. The classification is based on the chemical structure of the ionone skeleton with an additional methyl group. Under the General Rules for the Interpretation of the Harmonized System (GRI), specifically defined organic compounds like methylionones are classified in Chapter 29, even if they are intended for use as perfumery molecules, provided they are not yet mixed with other substances.

Products Included

• Alpha-Methylionone
• Beta-Methylionone
• Gamma-Methylionone (Isomethylionone)
• Delta-Methylionone
• Commercial mixtures of methylionone isomers

Common Misclassification

Methylionones are frequently misclassified under HS code 3302.90, which covers mixtures of odoriferous substances used as raw materials in industry. While methylionones are used in perfumery, a pure chemical isomer or a mixture of isomers of the same chemical compound remains in Chapter 29. Another common error is confusing them with Ionones (unmethylated), which are classified under the same sub-heading 2914.23 but must be distinguished in laboratory analysis. They should also not be confused with acyclic ketones found in 2914.19.

FAQ

What is the HS code for Methylionones?

Methylionones are classified under HS code 2914.23, which also includes standard ionones.

Are Methylionones considered essential oils?

No, methylionones are synthetic or isolated aromatic ketones and are classified as organic chemicals in Chapter 29, not as essential oils in Chapter 33.
