Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity below 94% by weight
Dipentaerythritol under 94% purity falls into the residual 'other' subheading within the same ether-alcohols category.
If pre-polymerized into alkyd resin
Polymerized forms exceed Chapter 29 scope and classify as synthetic resins in Chapter 39.
If imported as prepared additive mixture for paints
Mixtures exceeding 70% active ingredient classify as chemical preparations, not pure compounds.

Import Tips & Compliance
• Verify purity certificate from supplier showing ≥94% by weight to confirm HTS 2909.49.30.00 classification; lower purity shifts to 2909.49.40
• Include SDS and chemical analysis reports in documentation for CBP review to avoid reclassification
• Ensure proper UN packaging for Group III chemical (non-hazardous) to prevent transport delays
