This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used in paint/varnish production and imported as such a preparation
Paints and varnishes containing the solvent are classified in Chapter 32 by end use, not individual chemicals.
If when sold as a formulated industrial chemical mixture
Non-specific chemical mixtures for industrial use fall under 3824 rather than pure compounds of Chapter 29.
If considered primarily an alcohol rather than ether-alcohol
Principal function determines classification; alcohol-dominant compounds go to heading 2905.

Import Tips & Compliance
• Submit NMR or GC test results to verify chemical purity and monoalkyl ether structure during customs valuation
• Classify as hazardous material (UN 2709); ensure proper UN-certified packaging to prevent import rejections
• Avoid bulk imports mixed with water beyond note (d) limits, as excess solvent may trigger mixture classification
