Operational depth
built for industrial scale.
Every process — from supply planning to port delivery — is documented, auditable, and designed for counterparties who require certainty.
Planned supply,
not reactive procurement.
Our supply planning model is built around your production schedule, not ours. We integrate directly with your procurement calendar to ensure zero unplanned stockouts.
Rolling 12-Month Forecast
We issue quarterly supply schedules 90 days in advance, aligned to your plant's production calendar and buffer stock targets.
Grade Certification
Each consignment ships with a Certificate of Analysis from an accredited third-party assay house. Typical Sb grade: 99.50–99.85%.
Inventory Buffering
We maintain bonded warehouse stock at Rotterdam, Antwerp, and Durban to protect against shipping delays.
Dedicated Account Management
A single point of contact for all scheduling, documentation, and escalation — accessible on a 24/5 basis.

Bonded stock at three
major port terminals.
We manage our own bonded warehouse positions at Rotterdam, Antwerp, and Durban. This eliminates origin-to-plant transit risk and enables rapid drawdown against confirmed orders.
| Origin | Destination | Transit Time | Incoterm | Mode |
|---|---|---|---|---|
| Dushanbe, Tajikistan | Rotterdam, NL | 28–35 days | CIF | Rail → Sea |
| Johannesburg, ZA | Antwerp, BE | 22–28 days | CIF | Road → Sea |
| Johannesburg, ZA | Shanghai, CN | 18–22 days | CFR | Road → Sea |
| Rotterdam, NL | Customer Plant | 2–5 days | DAP | Road (Bonded) |
Rotterdam
1,200 t
Primary European hub. Bonded under Dutch Customs Warehousing.
Antwerp
800 t
Secondary EU hub. Integrated with rail connections to Central Europe.
Durban
600 t
African origin hub. Direct pipeline from Johannesburg smelter.
Settlement Workflow
A structured, auditable process from discharge through assay to
final payment, ensuring transparency and contractual certainty at every stage.
Shipment Loading & Sealing
Material loaded at bonded warehouse or origin port under supervised conditions. Lot numbers recorded, containers sealed, and pre-shipment weight certificates issued. Bill of Lading prepared with full traceability documentation.
Arrival & Discharge
Cargo received at destination port and discharged under terminal supervision. Seal integrity verified. Outturn weights recorded and compared against shipping documentation. Any discrepancies documented immediately.
Sampling & Moisture Determination
Representative samples collected in accordance with agreed international sampling standards. Moisture content determined to establish dry metric tonnage (DMT). Split samples prepared and sealed for both parties.
Primary Assay
Primary laboratory conducts chemical analysis to determine payable antimony content and impurity levels. Results shared with both parties along with certified assay report.
Umpire Assay (If Required)
If assay variance exceeds contractual threshold, sealed umpire samples are submitted to a mutually agreed independent laboratory. Umpire results are final and binding for settlement purposes.
Final Settlement
Final payable metal calculated based on agreed pricing formula (e.g., LME reference or fixed pricing). Commercial invoice issued reflecting DMT, assay results, and contractual deductions. Payment executed under agreed terms (LC or TT).
Fixed-price structures available for contracts ≤12 months. Multi-year contracts may incorporate annual price reset mechanisms indexed to CPI or LME rolling averages.
Designed to slot into
your existing process.
We understand that changing feed supplier is operationally disruptive. Our onboarding process is structured to minimise that disruption — from technical qualification to first production run.
Pre-Shipment Inspection
Joint PSI with your nominated inspector (SGS, BV, Intertek). Results released within 5 days of inspection.
Umpire Assay Protocol
If CoA is disputed, a mutually agreed umpire assay house resolves within 10 business days. Cost split 50/50.
Material Safety Data Sheet
Full MSDS provided per REACH and GHS standards. Dangerous Goods Declaration included for all shipments.
Customs Clearance Support
Our freight partners handle import customs at Rotterdam, Antwerp, and Durban. HS Code 2812.90 standard.
Waste & Packaging Returns
Empty drum collection available for EU customers under Extended Producer Responsibility schemes.
Technical Liaison
Our metallurgical team is available for technical queries on alloy specification, charging practice, and yield optimisation.
