HS Code for Anhydrous borax

Anhydrous borax, chemically known as disodium tetraborate, is classified under Harmonized System (HS) code 284011. This classification is highly specific, as the HS description for this subheading explicitly identifies "Borates; disodium tetraborate (refined borax), anhydrous." Anhydrous borax is a refined form of borax from which the water of crystallization has been removed, resulting in a dehydrated product. It is a significant inorganic chemical used in various industries, including glass manufacturing, ceramics, detergents, and metallurgy, due to its fluxing and buffering properties. Its precise classification under 284011 underscores its chemical identity as a refined, water-free borate compound.

Products Included

• Disodium tetraborate, anhydrous
• Refined borax, anhydrous
• Borax glass (a fused, anhydrous form)

Common Misclassification

A primary source of misclassification for anhydrous borax is with other forms of refined borax. Specifically, HS 284019 covers "Other disodium tetraborate (refined borax)," which includes hydrated forms such as borax decahydrate (Na₂B₄O₇·10H₂O) and borax pentahydrate (Na₂B₄O₇·5H₂O). The crucial differentiator is the presence or absence of water of crystallization. Anhydrous borax (284011) is explicitly water-free. Another potential confusion point is with HS 252800, which covers "Natural borates and concentrates thereof." Anhydrous borax (284011) is a *refined* chemical product, not a raw natural mineral, distinguishing it from unprocessed natural borates.

FAQ

What is the HS code for Anhydrous borax?

The HS code for Anhydrous borax is 284011. This code specifically covers disodium tetraborate (refined borax) in its anhydrous, or water-free, form.

How does anhydrous borax differ from other forms of refined borax in HS classification?

Anhydrous borax (284011) is the water-free form of disodium tetraborate. Other refined borax forms, such as borax decahydrate or pentahydrate, contain water of crystallization and are classified under HS 284019. The presence or absence of water is the defining characteristic for classification within these subheadings.
