HS Code 2911Acetals and hemiacetals; whether or not with other oxygen function, and their halogenated, sulphonated, nitrated or nitrostated derivatives

What HS code 2911 covers

Acetals and hemiacetals are organic compounds made from an aldehyde or a ketone and an alcohol. Customs offices group them in one place so that every country sorts them the same way. The heading belongs to the organic chemicals chapter of the Harmonized System.

The wording "other oxygen function" means the molecule may carry an extra oxygen group and still fit here. The heading also takes in derivatives of these goods. Those are versions where a halogen, a sulphonic group, a nitro group or a nitroso group has been added.

In short, if your product is an acetal or hemiacetal, or one of those derivatives, start your search at this heading. Some traders call it HSN 2911. The four digits are the same. The code 291100 is the number you will see on most forms and in most databases.

How 2911 differs from 2909, 2912 and 2940

Several nearby headings sound alike. The most common mix-up is between 2911 and 2909. Use the guide below to tell them apart.

• 2909: ethers and ether-alcohols, plus alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides and ketone peroxides. If the goods are a peroxide of an acetal, they go here and not under 2911.
• These are aldehydes, not acetals.
• Their key feature is a three-membered ring.
• A sugar acetal is sorted here, with a few listed exceptions.

Getting the classification right

Always read the full text of a heading, not only its short name. If two headings seem to fit, compare their wording side by side. Then check the notes in your own national tariff.

Countries add extra digits after the six-digit level, and each country sets its own duty and tax rates. This page does not quote any rates. Look them up in the tariff of the country you ship to or from.

If you are still unsure, try the HS code classifier. You can also browse the other families of organic chemicals in the chapter page, or look at the list of all HS code chapters to see how the whole system is laid out.

Find importers and suppliers of acetals

Once you know your goods fall under this heading, the next step is to see who trades them. A code is the easiest way into customs records.
