What products fall under HS-4 2911?

HS-4 2911 includes acetals and hemiacetals, along with their halogenated, sulphonated, nitrated, or nitrosated derivatives.

How do I know if my product is an acetal or hemiacetal?

An acetal has two alkoxy groups attached to the same carbon, while a hemiacetal has one alkoxy and one hydroxyl group. Check your product's chemical structure to determine its classification.

Are there any specific import regulations for halogenated acetals?

Yes, halogenated acetals may be subject to additional regulations due to environmental concerns. Always check local regulations before importing.

Can I use HS-4 2911 for mixed products?

Yes, as long as the product contains acetals or hemiacetals, even if mixed with other oxygen functions, it can be classified under HS-4 2911.

What should I do if I'm unsure about the HS code?

Consult with a customs broker or refer to the Harmonized System guidelines for assistance in determining the correct HS code for your product.

HS-4 · Heading

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

Chapter 29: Organic chemicals

Plain-language overview

Use HS-4 2911 when importing acetals and hemiacetals, such as butylidene diacetate, which may be used in chemical synthesis or as solvents. This heading covers products that contain these compounds, whether they are pure or mixed with other oxygen functions.

When deciding between HS-6 291100, consider whether your product is a pure acetal or hemiacetal or if it includes additional oxygen functions. For example, if your shipment consists of a halogenated acetal, it still falls under this classification, but you should be aware of any specific regulations regarding halogenated compounds.

If you are unsure whether your product fits under this heading or a neighboring one, check the specific chemical structure. For example, if your product is a simple acetal without any additional functional groups, it clearly belongs to HS-6 291100. However, if it has been chemically modified, you may need to look at other classifications.
