Last updated: August 2026 dataHydrated forms of disodium tetraborate — commonly known as borax — are a foundational boron source for glass fiber, ceramics, and agricultural micronutrient applications. Turkey dominates global supply of this mineral, reflecting its vast borate ore reserves, with Guatemala and Italy also among the leading US import sources. Classified under a single 10-digit line (2840190000), the heading excludes anhydrous disodium tetraborate, making the hydration state the critical classification distinction at entry.

The key is water of crystallization: hydrated forms (e.g., borax decahydrate and pentahydrate) fall under 284019, while the anhydrous form is classified separately. Importers should confirm the product's water content via the supplier's certificate of analysis before filing entry.
Turkey holds some of the world's largest commercially exploitable borate ore deposits, giving Turkish producers a significant cost and volume advantage. This concentration means US buyers in glass fiber and ceramics industries closely monitor Turkish export policy and logistics disruptions.
