Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when neutralized and packaged as household detergent
Neutralized forms in retail packs are classified as surface-active preparations in Chapter 34.
If it's the ethyl ester rather than acid or salt form
Ethyl esters of aromatic sulfo derivatives have specific statistical classification within the same heading group.

Import Tips & Compliance
• Include sulfonation process documentation and alkyl chain length specs to confirm classification as aromatic sulfo derivative
• Ensure product is not ethyl ester form, which has separate statistical breakout within the heading
• Test for halogenation; presence of halogens changes classification within 2904 subheadings
