As global supply chains place an unprecedented premium on critical and strategic minerals, antimony ore (Stibnite, Sb₂S₃) has emerged as one of the most vital raw materials in international metallurgy and advanced manufacturing. Pakistan possesses rich, high-grade geological reserves of antimony situated primarily across the mineral-rich belts of Balochistan (Qila Abdullah and surrounding districts) and northern mountainous reserves in Gilgit-Baltistan.
World Trade Management (WTM) operates as an established Pakistani mining representative and mineral exporter headquartered in DHA Karachi. WTM manages end-to-end extraction oversight, rigorous laboratory assay testing, customs processing, and containerized ocean export via Karachi Port (KICT/PICT/SAPT) to international smelters, chemical refineries, and industrial buyers worldwide.
Antimony (chemical symbol Sb, atomic number 51) is classified as a critical mineral by industrial economies across North America, the European Union, and East Asia due to tight global supply and lack of direct substitutes in essential sectors:
WTM supplies naturally occurring Stibnite ore processed to international smelter and processing standards. Each consignment is tested by accredited geochemical laboratories prior to dispatch:
| Technical Parameter | Specification / Guaranteed Range | Test Method |
|---|---|---|
| Mineral Form | Stibnite (Sb₂S₃) crystalline sulfide ore | XRD / Mineralogical Analysis |
| Antimony (Sb) Content | 20% to 55%+ Sb (Custom lots graded per buyer specification) | ICP-OES / Wet Chemical Titration |
| Moisture Content | Less than 3.0% Max at loading | Oven Dry Basis (105°C) |
| Physical Sizing | Lumps (10mm – 100mm) or Crushed Gravel (0mm – 25mm) | Screen Mechanical Analysis |
| Packaging | 1,000 kg Heavy-Duty UV-stabilized Woven Polypropylene Jumbo Bags | Standard Industrial Export Packaging |
| Minimum Order Quantity (MOQ) | 1 x 20ft FCL Container (~20 to 25 Metric Tons) | Ocean Container Freight |
| Delivery Terms | FOB Karachi Port / CFR or CIF Main World Ports (Incoterms 2020) | Containerized Liner Shipping |
WTM follows a transparent, internationally compliant export procedure to guarantee grade compliance and seamless delivery:
Step 1 — Requirement Specification & Assay Target
The buyer indicates desired Sb content (e.g., 30%, 45%, or 50%+ Sb), physical size requirements, destination port, and expected shipment volume.
Step 2 — Representative Sampling & Lab Assay
Representative samples are drawn from mine stockpiles and analyzed by recognized laboratories. Sealed samples and assay certificates are provided to the buyer for verification.
Step 3 — Commercial Contract & Payment Instrument
Mutually agreed sales contract executed with clear pricing based on dry metric ton units (DMTU) or flat MT pricing, backed by confirmed Letter of Credit (LC) or standard international wire terms.
Step 4 — Port Consolidation, Bagging & Pre-Shipment Inspection
Ore is transported to Karachi port staging warehouses, weighed, stuffed into 1MT jumbo bags, containerized, and made available for optional third-party surveyor verification (SGS / Alfred H Knight).
Step 5 — Customs Clearance & Shipping Documents Release
Full documentation set dispatched: Clean on Board Bill of Lading, Certificate of Origin (COO) issued by Karachi Chamber of Commerce (KCCI), Commercial Invoice, Packing List, and final Assays.
Antimony ore prices are benchmarked against international metal exchange quotations and calculated according to the net contained antimony percentage per metric ton. In 2026, typical pricing benchmarks for Pakistani origin ore range as follows:
In addition to antimony ore, WTM manages regular export shipments of Pakistani minerals through its dedicated raw materials division:
