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.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with >10% stabilizers or solvents beyond Chapter 29 allowances
Mixtures of organic compounds with additives exceeding simple stabilization fall under prepared chemical mixtures, not pure compounds.
If imported as saturated fatty alcohol derivative for specific applications
Certain saturated acyclic alcohols classified by function may shift to oxygen-function compounds if not purely diols.
If supplied as sugar ethers/esters rather than simple diol
Sugar-derived derivatives fall under heading 2940, later in numerical order per classification note.

Import Tips & Compliance
• Provide Certificate of Analysis (COA) confirming purity >99% as neopentyl glycol to avoid reclassification as mixtures
• Ensure proper UN 3077 packaging for Environmentally Hazardous Substances and include SDS documentation
• Verify CAS number 126-30-7 on labeling to prevent customs holds for misidentified organic chemicals

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.
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.
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.
