Feed Grade Magnesium Sulphate Lot Certified for Export

A Certified Lot for Feed Programmes

MgSO4 Group Limited has released a newly certified feed grade magnesium sulphate lot for export, with heavy-metal and assay documentation completed against feed-industry requirements. The release follows a full production and inspection cycle at our own plant.

Feed mills and premix houses need traceable lot identity, so each shipment carries a COA tied to a specific production batch rather than a generic specification sheet.

Use in MgSO4 Animal Feed

In MgSO4 animal feed applications, magnesium supports enzyme activity, bone mineralisation and nerve function across poultry, swine and ruminant rations. Soluble sulphate forms blend uniformly into premixes and contribute sulfur at the same time.

Inclusion rate should always be set by a nutritionist against the basal ration and drinking water analysis, since excess magnesium affects overall mineral balance.

What Feed Additive Certification Covers

feed additive certification for this lot covers assay, heavy-metal ceilings, moisture and particle characteristics, together with a documented chain from raw material intake to finished packing. Third-party inspection is available where destination authorities require it.

Buyers should request the certificate set at the order stage so that their own registration dossier can reference the exact lot before shipment.

Magnesium Sulphate Monohydrate Basis

The lot is based on magnesium sulphate monohydrate at approximately 20% MgO, a compact and stable source that gives predictable inclusion per kilogram of premix. Its lower water content improves storage behaviour compared with fully hydrated grades.

Confirm the particle size against your mixer, since a fine powder behaves differently from a granular grade in a high-speed premix line.

Heavy Metal Limits in Practice

heavy metal limits are the decisive specification for feed-grade material, and they must be stated as numeric ceilings rather than as a general compliance claim. Our COA reports the actual result for each listed element against the agreed limit.

Where a destination applies a tighter national threshold, declare it at enquiry stage so the lot can be selected or tested against the correct requirement.

As a Premix Magnesium Source

Used as a premix magnesium source, the material must disperse evenly to avoid hotspots in the final feed. We recommend validating mixing time and sequence in your own plant, then checking uniformity with a tracer or assay across several sample points.

A consistent particle-size distribution matters more here than a marginal difference in assay, because segregation undermines even a correctly calculated inclusion rate.

Sampling and Retention

Retain a sealed reference sample from each lot at both the supplying and receiving end. If a question arises about assay or flow, the retained material resolves it quickly and protects both parties.

Our packing list and lot marking are designed to make that retention straightforward, with the batch code visible on each bag.

Ordering and Documentation

Share your target inclusion rate, mixer type, packing format and destination requirements, and we will match the lot and document set accordingly. Samples are available for a plant trial before a full order is placed.

We also supply heptahydrate and magnesium oxide feed grades where a programme calls for a different magnesium concentration or particle form.
