Boron Products

Türkiye holds 72% of the world's proven boron reserves. Global Trading sits at the source.

Seven Eti Maden boron products — boric acid, borax pentahydrate (Etibor-68), borax decahydrate (Etibor-48), boron oxide, ground colemanite, ground ulexite, and disodium octaborate (Solubor) — supplied from Istanbul with full production-batch COA, MSDS, certificate of origin, and REACH registration documentation. Direct Turkish-origin supply eliminates the European redistribution layer that most buyers unknowingly pay.

The Turkish boron supply chain — and where Global Trading sits within it

Origin-priced supply · Zero redistribution margin

Eti Maden İşletmeleri Genel Müdürlüğü — the Turkish state mining enterprise — is the world's largest producer of refined boron products, operating four mine sites and five processing facilities across western Anatolia. Eti Maden's international sales reach buyers through its Geneva-based subsidiary Etimine SA (Europe and global) and through Etimine USA. Buyers who do not meet minimum direct tonnage thresholds purchase from distributors who have acquired material from Etimine — adding a redistribution margin, additional transit handling, and extended lead time to every tonne they buy. As an Istanbul-based company with a direct Eti Maden supply relationship, Global Trading removes that redistribution layer entirely, providing industrial manufacturers with access to origin-priced material, same-week indicative pricing, and flexible FCL or LCL supply from Turkish export ports.

Compared with approximately 11% in the USA (Boron, CA) and 9% in Russia. The structural supply advantage is permanent — it is geology, not policy.
