HS Code for Ionones

Ionones are a series of closely related chemical substances that are part of the ketone family, widely used in the fragrance and flavor industries for their distinct violet-like scent. They are classified under HS code 2914.23. Chapter 29 covers organic chemicals, and heading 2914 specifically addresses ketones and quinones. Subheading 2914.23 is dedicated to ionones and methylionones. These are cyclenic ketones that do not contain other oxygen functions (such as alcohol or aldehyde groups). The classification is based on the molecular structure of the compound. Even though ionones are often derived from citral through chemical synthesis, their final structure as a cyclic ketone dictates their placement in this specific category. This code covers both the alpha and beta isomers, which are the most common forms found in industrial trade.

Products Included

• Alpha-ionone
• Beta-ionone
• Gamma-ionone
• Methylionones
• Pseudo-ionone
• Commercial ionone mixtures

Common Misclassification

Ionones are frequently misclassified under HS code 3302.90, which covers mixtures of odoriferous substances used as raw materials in industry. While ionones are odoriferous, heading 2914 takes precedence if the product is a separate chemically defined organic compound. They may also be confused with 2914.29 (other cyclanic ketones), but 2914.23 is the specific sub-heading that must be used for ionones.

FAQ

What is the HS code for ionones?

The HS code for ionones and methylionones is 2914.23.

Are ionones classified differently if used in food?

No, even when used as flavoring agents in the food industry, separate chemically defined ionones remain classified under 2914.23 based on their chemical structure.
