SD Eastern Bhutan Ferro Silicon Private Limited

What SD Eastern Bhutan Ferro Silicon Private Limited does

SD Eastern Bhutan Ferro Silicon Private Limited (SDEBFSPL) is a Bhutan-based ferroalloy manufacturer incorporated on 5 May 2004 under the Companies Act of the Kingdom of Bhutan, headquartered in Samdrup Jongkhar with production at the Motanga Industrial Estate. The company operates 2x9MVA submerged-arc furnace capacity and produces three related product lines: standard Ferro Silicon across multiple grades (45-50%, 70%, 72%, and 75% minimum silicon content), Ferro Silicon Magnesium master alloys launched commercially in May 2019, and Inoculants for grey and S.G. iron foundries. Manufacturing emphasizes low impurity levels (low carbon, calcium, and aluminum) achieved through careful raw material screening and washing, with downstream products relying on in-house produced low-impurity FeSi as feedstock — a vertical integration that supports quality control and is verified through an XRF laboratory installed in April 2019.

The company serves a B2B industrial customer base consisting of iron and steel manufacturers (which use FeSi in high-quality steel and special alloy production) and foundries producing S.G. (ductile) iron, with products customized across grades, sizes, and packing formats to customer specifications. Pricing is not publicly disclosed and is handled via direct quote, consistent with a relationship-driven, specification-based industrial sales model. Geographic reach is anchored by India as the primary export market since incorporation, with additional sales to other Asian countries and emerging inroads into European markets. The company holds ISO 9001, ISO 14001, and ISO Health and Safety Working Environment certifications, and is operated as a privately held entity majority owned by Chairman Sonam Dukpa.

Commercial reach is conducted through direct enterprise sales rather than formal distributor or channel partnerships, with the corporate website (sdbhutan.com) functioning as the primary digital presence. Bank of Bhutan Limited is the only identified financial counterpart. No M&A, institutional funding rounds, subsidiaries, or public capital markets activity are referenced in the available material, and the company's reported headcount of 8 appears inconsistent with the operational footprint implied by two 9MVA furnaces — suggesting either outsourced labor, automation-heavy operations, or an undercounted workforce.

Core offering

SD Eastern Bhutan Ferro Silicon Private Limited manufactures and exports ferro silicon, ferro silicon magnesium, and ferro silicon-based inoculants from its plant in Samdrup Jongkhar, Bhutan. Products are sold in multiple grades, sizes, and packing configurations directly to iron and steel manufacturers and foundries across India, other Asian countries, and Europe.

Product overview

S.D Eastern Bhutan Ferro Silicon Private Limited is a ferroalloy manufacturing company producing three related product lines. Ferro Silicon serves as the foundational product, an iron-silicon alloy available in multiple grades (45-50%, 70%, 72%, 75% silicon content) used in iron and steel production. Ferro Silicon Magnesium is a master alloy adding magnesium to enhance graphite structure and tensile strength in S.G. (Spheroidal Graphite) Iron. Inoculants are specialized ferro-silicon based alloys that control matrix structure and prevent casting defects in grey and S.G. Iron. All three products are manufactured at the company's plant in Samdrup Jongkhar, Bhutan, using 2x9MVA furnace capacity with in-house produced low-impurity ferro silicon as raw material for downstream products.

Products and services

• Ferro Silicon Ferro silicon is a ferroalloy composed of iron and silicon, available in grades 45-50% Si, 70% min Si, 72% min Si, and 75% min Si, with very low carbon, calcium, and aluminum impurities. Sizes available are 3mm-10mm, 10mm-40mm, and 10mm-50mm, with packing in 40kg gunny bags with HDPE inner bags or 1000kg jumbo bags. Intended for iron and steel manufacturers producing high-quality steel and special alloys.
• Ferro Silicon Magnesium Ferro silicon magnesium is a master alloy of magnesium with iron and silicon, where magnesium produces the required graphite structure that imparts tensile strength and elongation to S.G. Iron (ductile iron). Available in various combinations of Magnesium, Calcium, and Rare Earth to suit foundry process needs, in sizes 2mm-10mm, 2mm-15mm, 5mm-20mm, 5mm-25mm, and 5mm-32mm, with packing options of 25kg, 500kg, and 1000kg. Intended for foundries producing S.G. Iron castings.
• Inoculants Inoculants are ferro silicon-based highly potent alloys used to inoculate grey and S.G. Iron to control matrix structure and avoid casting defects. Different inoculant types are available for different bearings, produced with low-impurity ferro silicon. The product stabilizes nuclei for longer periods, prevents chill problems, and reduces shrinkage in castings. Sizes available are 0.2mm-0.7mm, 1mm-3mm, and 2mm-6mm, with packing in 25kg, 500kg, and 1000kg options. Intended for foundries inoculating grey and S.G. Iron.
