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.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-formulated as pharmaceutical preparation rather than bulk chemical
Medicinal preparations exclude bulk organic chemicals; Chapter 29 applies only to separate compounds.
If with pharmaceutical excipients beyond stabilization allowances
Exceeds Chapter 29(g) limits for identification additives; becomes prepared mixture.

Import Tips & Compliance
• Include USP/EP certificate and endotoxin testing results to differentiate from industrial grades
• Declare as 'bulk active pharmaceutical ingredient intermediate' with DMF reference if applicable
• Ensure packaging prevents moisture absorption to maintain diol classification vs hydrated forms

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.
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.
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.
