Neopentyl Glycol for Polyurethane Production
Specialty grade neopentyl glycol used as chain extender in polyurethane elastomers and coatings. This pure acyclic diol falls squarely under 2905.39.20.00 as specified for neopentyl glycol, distinct from common diols like ethylene glycol.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nitrogen-functional derivatives present beyond trace impurities
Chapter notes exclude nitro/nitroso from nitrogen functions, but other N-derivatives shift classification.
If for cyclic ether derivatives rather than acyclic diol
Cyclization changes from acyclic alcohols (2905) to heterocyclic compounds (2932).

Import Tips & Compliance
• Batch certificates showing <0.1% water content prevent classification disputes over hydrated forms
• Use HTSUS Special Provision language for 'synthetic organic chemicals' to expedite release
• Pre-clear REACH/ TSCA compliance documentation as condition for chemical import release

Neopentyl Glycol (NPG) Flakes
Neopentyl glycol is a chemically defined acyclic diol (2,2-dimethyl-1,3-propanediol) used primarily in the production of polyester resins and plasticizers. This product is imported as white crystalline flakes, meeting Chapter 29 note (a) for separate chemically defined organic compounds. Classified under 2905.39.20.00 as a diol other than ethylene or propylene glycol.
Industrial Grade Neopentyl Glycol Powder
High-purity neopentyl glycol powder (>99.5%) used in manufacturing alkyd resins for paints and powder coatings. As a separate acyclic diol, it qualifies under heading 2905 per Chapter 29 notes (a) and (f) allowing stabilizers for transport. Specifically identified under 2905.39.20.00 as 'other' diols.
Pharmaceutical Grade Neopentyl Glycol USP
Ultra-pure neopentyl glycol meeting USP standards for use in pharmaceutical intermediate synthesis. As a chemically defined diol without excluded characteristics, properly classified under 2905.39.20.00 rather than medicinal preparations.
Neopentyl Glycol Stabilized for Transport
Neopentyl glycol with 0.05% anticaking agent added per Chapter 29 note (f) for safe bulk transport. Remains classified as pure diol under 2905.39.20.00 since stabilizer is necessary for preservation, not specific use.
High-Purity Neopentyl Glycol for Resins
Distilled neopentyl glycol (99.8% purity) specifically for unsaturated polyester resin production. Meets all Chapter 29 criteria as separate acyclic diol, subheading 2905.39.20.00.
