Distilled Water USP Grade
USP-grade distilled water is highly purified water meeting United States Pharmacopeia standards for pharmaceutical use. It is classified under HTS 2853.90.90.90 as 'distilled or conductivity water and water of similar purity' within other inorganic compounds. Produced by distillation to remove impurities, ensuring <1 µS/cm conductivity.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not of 'similar purity' and intended for drinking
Ordinary drinking water falls in Chapter 22; only distilled/conductivity grades stay in 2853 per heading scope.
If modified with additives for diagnostic or lab reagents
Purified water as a reagent component shifts to 3822 for diagnostic/lab preparations.
If sold in sterile form as pharmaceutical diluent
Waters put up for pharmaceutical retail sale may classify under Chapter 30 as pharmaceutical goods.

Import Tips & Compliance
• Provide USP certificate of analysis for FDA entry; use sterile containers to maintain purity
• Avoid classification as beverages (Chapter 22) by proving pharmaceutical end-use
• Label conductivity specs clearly
