2909.49.30.00 - Dipentaerythritol having a purity of 94 percent or more by weight

This HTS classification, 2909.49.30.00, specifically covers dipentaerythritol when it possesses a purity of 94 percent or more by weight. Dipentaerythritol is a polyhydric alcohol, a complex organic compound derived from pentaerythritol through ether linkages. Its primary applications lie in the production of alkyd resins, synthetic lubricants, plasticizers, and as a component in explosives and printing inks, where its high degree of etherification and hydroxyl groups contribute to desirable properties.

This specific entry is distinguished from its sibling categories primarily by the chemical identity and purity of the alcohol. While 2909.49.20.00 covers glycerol ethers, this classification focuses solely on dipentaerythritol, a distinct and more complex polyol. The sibling 2909.49.60.00, "Other," serves as a residual category for ether-alcohols not specifically enumerated elsewhere within the "Other" subheadings. The crucial classification criterion here is the 94% purity threshold, ensuring that only high-grade dipentaerythritol is captured under this specific code.

As a leaf node, there are no further subcategories beneath 2909.49.30.00. Therefore, classification at this level is definitive and relies on verifying the chemical identity as dipentaerythritol and confirming its purity meets or exceeds the stipulated 94 percent by weight, as evidenced by appropriate analytical documentation.
