Trace minerals RFQ
Request a trace mineral quote — sulphates, oxides, hydroxy and chelates
Trace mineral offers are frequently compared on the wrong basis — price per tonne of salt rather than cost per unit of element delivered, with different bioavailability and contaminant limits behind each. Tell us the elements, source forms and volumes you need and we issue a structured RFQ with assay, heavy-metal limits and analytical method fixed in advance.
- Zn, Cu, Mn, Fe, Se, I, Co and Cr
- Sulphate, oxide, hydroxy and chelated forms
- Cost per unit of element, delivered
- Heavy-metal and dioxin limits fixed in the RFQ
What a complete trace minerals RFQ must contain
- Element list with annual and per-shipment tonnage
- Source form and guaranteed element assay per line
- Heavy-metal, dioxin and particle-size limits
- Analytical method used to verify assay
- Packaging, pallet configuration and moisture protection
- Incoterm, destination and required certification scope
Frequently asked questions
How should trace mineral offers be compared?
Always on delivered cost per unit of the element itself, not per tonne of salt. Divide the landed cost by the guaranteed element assay, then apply the inclusion rate your formulation requires. Zinc sulphate monohydrate at roughly 35% Zn and zinc oxide at roughly 72% Zn look very different per tonne and can be identical per unit of zinc.
Are hydroxy or chelated trace minerals worth the premium?
They can be where bioavailability, antagonism in the premix or reduced excretion matters, and where regulatory limits force lower inclusion. Quantify it: compare the delivered cost per unit of element multiplied by the inclusion rate each form actually needs in your matrix, rather than accepting a bioavailability claim without supporting data.
Which contaminant limits should I write into the RFQ?
For EU destinations, the maximum levels of Directive 2002/32/EC for lead, cadmium, arsenic, mercury, fluorine and dioxins apply and should be stated explicitly, along with the analytical method. Mineral sources are the highest-risk category for heavy metals, so require a recent third-party certificate of analysis and reserve the right to independent sampling on arrival.
Can I buy several elements from one supplier?
Often yes, and consolidating elements into one shipment reduces freight and documentation cost. Suppliers quoting through FeedMatch price each element line separately so you can still award line by line if a mixed award is cheaper overall.
