Full-Spectrum Transaction Coordinator
Iron Circle acts as transaction coordinator, intermediary, and principal across six commodity categories. In each, the role is the same — trusted intermediary, precise documentation, and execution that holds.
Gold & Precious Metals
London Good Delivery specification. 999.9 fine purity. LBMA-compliant documentation. Lot sizes from 1kg to metric-ton scale. Every transfer accompanied by full chain-of-custody documentation and independent assay certification.
Mine-to-refinery transaction coordination for Dore ore, nuggets, and pre-refined gold. Sourced at mine-gate through accredited partner refineries. Full provenance chain documented at each custody point to ensure conflict-mineral compliance.
Diamonds & Gemstones
Iron Circle facilitates certified diamond and gemstone transactions exclusively for qualified principals. All lots carry GIA or IGI grading certification. Kimberley Process compliance is non-negotiable. Vault-to-vault transfer logistics are arranged through vetted, insured secure-transport partners. Discretion is absolute.
Iron Ore
High-grade iron ore for steel production and industrial application. Fe 62–65% specification. Bulk cargo coordination via Capesize and Panamax vessels. SGS quantity and quality inspection at load port. Certificate of origin, export permits, and full port documentation included in every transaction package.
Coal
API2 and API4 benchmark thermal coal for power generation, cement production, and industrial application. Full mine-to-port documentation with SGS calorific value and quality certification.
Coking coal for steel production. Low-ash, low-sulphur specification. Supply chain coordination for integrated steel mills and mini-mills requiring reliable long-term off-take arrangements.
Copper
LME-grade copper cathodes and concentrates. Grade A cathode at 99.99% purity. Supply coordination for industrial manufacturers, wire rod producers, and commodity trading desks. LME-registered warrant eligibility maintained where applicable.
Fuel & Energy
EN 590:2013+A1 specification, 10ppm sulphur maximum. CIF Rotterdam or ASWP delivery. Full ICPO-to-BCL documentation workflow. SGS quantity and quality inspection confirmed at load port.
Virgin and non-virgin D6 residual fuel oil to Colonial pipeline specification. Power generation, bunkering, and downstream refinery application. Bulk cargo via VLCC and Aframax.
ASTM D1655 and DEF STAN 91-091 compliant aviation turbine fuel. Sourced from accredited refineries. Airport delivery, into-plane fueling, and bunkering coordination for commercial and charter principals.
Industrial & Specialty Minerals
High-calcium limestone for cement manufacturing, agricultural soil amendment, and industrial processing. Bulk cargo coordination with full chemical-analysis certification and SGS quality inspection at load port.
Premium-grade zircon sand and zircon flour for ceramics, refractories, and foundry applications. High ZrO₂ content specification. Full mineralogical certification and provenance documentation provided per lot.
Lead concentrates and refined lead ingot for battery manufacturing, radiation shielding, and specialty alloys. Sourced from regulated, permitted operations. Full environmental and export compliance documentation included.
Cassiterite concentrate and refined tin for electronics soldering, food-grade canning, and specialty alloy production. Conflict-mineral due diligence completed. ITRI iTSCi and equivalent chain-of-custody documentation available.
Ilmenite ore and concentrate for titanium dioxide pigment production and aerospace titanium sponge feedstock. Specified by TiO₂ content. SGS mineralogical analysis at load port. CIF and FOB terms structured to buyer requirements.
Zinc concentrates and refined zinc ingot for galvanizing, die-casting, and brass alloy production. LME-grade SHG zinc available. Supply coordination for steel galvanizers, die-casters, and chemical manufacturers requiring consistent off-take.
Natural rutile sand for high-TiO₂ pigment manufacturing and welding rod flux coating. Superior feedstock grade versus synthetic alternatives. Comprehensive mineralogical certification and provenance chain provided per shipment.
Niobium concentrate and ferroniobium for high-strength low-alloy steel production and aerospace superalloy applications. Full conflict-mineral due diligence and export documentation. Coordinates with certified processing facilities for FeNb conversion.
Gibbsite and boehmite bauxite for alumina refining, supporting downstream aluminum production for transport, construction, and packaging sectors. Bulk cargo coordination with SGS Al₂O₃ grade certification and full port documentation.
