Other Minerals
The list above is where we operate most often. It is not a limit.
If you buy a mineral raw material that is not shown here, send us the specification and the volume you need. We will look for it and tell you honestly whether we can supply it.
The figures shown are typical values from the producers we work with. The binding specification for any shipment is the certificate of analysis issued for that lot, which travels with the goods.
Water Treatment
Filter Media for Iron and Manganese Removal
Our second line of business. Natural manganese dioxide (MnO2) is a filter medium widely used across Europe to remove iron and manganese from groundwater and drinking water. We supply it to water treatment companies, filter builders and distributors, with the same sourcing discipline and documentation as our feed range.
The media works by catalysis rather than by being consumed. Dissolved iron and manganese are oxidised at the grain surface and held back in the filter bed, which is then recovered by backwashing. Part of the arsenic, aluminium and hydrogen sulphide present in the raw water is removed along with them.
Natural manganese dioxide, filter media grade MnO₂ Data sheet
Crushed and graded natural ore, with nothing added to it. The 0.5 to 1.0 mm cut is the general purpose grain for iron and manganese removal beds. If your bed design calls for a different range, tell us the range with the enquiry.

Additives None
| Parameter | Typical specification |
|---|---|
| Manganese dioxide (MnO₂) | 78% |

Who We Are
Experience in Minerals, Based in Rotterdam
Most mineral raw materials used in European feed and water treatment are produced far from where they are used. Between the producer and your plant there is a specification to match, a certificate of analysis to check, a freight route, customs clearance and the paperwork for each step.
Tracer Gate manages that chain for you, with one point of contact in Europe.
Our team comes from the mineral industry and international trade. We know how these products are made, which parameters vary from lot to lot and which documents your quality department will ask for. If a specification or a delivery date is at risk, you hear it from us before the goods are shipped.
- Based in Rotterdam. Europe’s largest port and a main entry point for bulk minerals, in the same time zone and business culture as our clients.
- Producers we qualify ourselves. Before we offer a material we look at the plant, its quality system and real production data, not at a data sheet alone.
- Terms set per client. Volumes, packing, delivery schedule and incoterm follow your production plan.
We only confirm what we can deliver. If a specification, a volume or a date is out of reach, we
tell you before you place the order.
The Process
How an Order Works
From the first enquiry to delivery at your site, the same person at Tracer Gate follows your order.
Sourcing
We check your specification against producers we have qualified and confirm grade, availability and lead time.
Offer
You receive a written offer with price, incoterm, packing, lead time and the documents that travel with the goods.
Shipment
Freight is booked and the shipping documents are prepared in parallel, so the paperwork is ready before the goods arrive.
Delivery
Delivery at your port of discharge (CIF) or at your plant (DDP), with the certificate of analysis for the lot.
What We Do
What We Handle for You
Sourcing, quality documentation, logistics and commercial terms, handled by one team.
Sourcing and Supplier Qualification
We buy from producers we have assessed ourselves: the plant, the quality system and the consistency from lot to lot. Where a material allows it, we keep more than one qualified source, so a stoppage at one producer does not stop your production.
- Producers assessed before we make an offer
- Specification checked against real plant output
- More than one qualified source where possible
Quality and Compliance
Tracer Gate is GMP+ FSA certified for trade in feed materials and feed additives. Every lot ships with its certificate of analysis, and we provide the documents your quality department needs for supplier approval. We know the EU limits that apply to each trace element and species, and where a specification tends to fail.
Flexible Logistics
We deliver DDP to your plant across Europe, the USA and Canada, and CIF to the port you name anywhere else. Packing in big bags or as you specify, with the route chosen per shipment for cost and lead time.
Volumes and Commercial Terms
Spot purchases and recurring supply programmes are both possible. Volume, packing and delivery frequency are agreed per client, in line with how you plan production.
Incoterms
How We Deliver
Two standard ways to buy from us. Both are quoted with freight and documents included, so the price on the offer is the price at the agreed delivery point.
Delivered to Your Plant
Across the whole of Europe, the USA and Canada we sell DDP. We take the goods from the producer to your gate, and we carry the freight, the import clearance, the duties and the inland leg. You receive the material, check it against the certificate of analysis and nothing else has to be arranged on your side.
- Europe, including the European Union, the United Kingdom, Switzerland and Norway
- The United States and Canada
- Ocean freight, customs clearance, duties and inland transport in one price
- Delivery to the plant, to a warehouse or to a third party on your instruction
Landed at Your Port
To every other country we sell CIF. We arrange the ocean freight and the cargo insurance to the discharge port you name, and we hand over a clean set of shipping documents. Your own broker takes it from there, which is how most buyers outside Europe, the USA and Canada prefer to work.
- Any discharge port in any country we are able to ship to
- Ocean freight and cargo insurance included to the named port
- Full document set, including certificate of analysis and certificate of origin
- Other incoterms such as FOB or EXW quoted on request
Whichever term applies, the goods travel under our GMP+ Feed Safety Assurance scope and the documentation is prepared to the standard a European buyer expects.
Assurance
Certification
Tracer Gate operates under GMP+ Feed Safety Assurance. Copies of our certificate are available on request.
Scope and validity can be verified in the GMP+ International company database.
