Buyer intent coverage
Sodium selenite (feed grade) — what it is, where it is used, how it is chosen
Sodium selenite is the classical inorganic selenium source and is handled almost exclusively as a diluted premix because the inclusion rate in finished feed is measured in grams per tonne. Canadian buying sits with the Prairie and Ontario premix and micro-ingredient blenders who serve poultry, swine and ruminant mills, and selenium is a regulated micro-ingredient, so the maximum permitted level in the finished feed is a regulatory question the buyer confirms for their jurisdiction and species.
Primary uses
- Supplying selenium in vitamin and trace mineral premixes
- Selenium supplementation programmes in ruminant and monogastric feeds
- Manufacture of diluted selenium premixes for safe mill handling
Applications
- Premix and micro-ingredient blending
- Mineral supplement manufacture
- Complete feed production through a premix route
Advantages
- Low cost per unit of selenium delivered
- Long-established analytical and regulatory position
- Available as a dilution designed for safe mill handling
Limitations to consider
- Toxic at low multiples of the nutritional level, so accuracy is critical
- Handling the concentrated form requires strict controls
- Inorganic selenium is not equivalent to selenium yeast in tissue deposition claims
How to choose the right grade
- Decide whether you are buying the pure salt or a declared dilution
- Confirm the permitted selenium level for the species and jurisdiction
- Verify mixer accuracy and validation at the intended inclusion
- Buyers searching for an alternative or second-source supplier should state the incumbent specification they are matching, because a like-for-like comparison depends on declared content, physical form and documentation rather than on the material name alone.
Typical grades
- Sodium selenite pure feed grade
- 1% selenium diluted premix

Procurement coverage
How to specify, order and receive Sodium selenite (feed grade)
Written for procurement, quality and technical buyers in Canada and the United States. No numeric price, MOQ, stock or lead-time value is published — those are confirmed per shipment in the quotation and against the confirmed batch.
How buyers specify at RFQ
- Declared element content and the assay method
- Particle size and dustiness for premix blending
- Heavy metal, dioxin and contaminant limits for feed use
- Carrier or dilution basis where the material is sold diluted
- Whether the pure salt or a stated dilution is required
Packaging options (industry-standard)
- 25 kg bag or fibre drum — the usual micro-ingredient format
- Foil-lined or moisture-barrier packaging for hygroscopic and oxidation-sensitive actives
- Carton or pail for very low-inclusion actives handled by hand
- Packaging options and available pack sizes are confirmed with each quotation.
Storage & handling
- Store sealed, dry and under controlled access as a potent micro-ingredient
- Use dedicated scoops, scales and mixing equipment with documented cleaning
- Record batch numbers and inclusion checks for every blend
Documentation available
- Technical data sheet (TDS) for the exact feed grade offered
- Safety data sheet (SDS) in the format required for Canadian import
- Certificate of analysis (COA) against the confirmed production batch
- Feed-ingredient declaration and label statements the receiving mill needs
- Documentation is confirmed per batch at quotation; availability depends on the grade and supplier offered.

Technical & procurement detail
Functional role of sodium selenite in feed+
Selenium is a component of glutathione peroxidase and works with vitamin E in antioxidant defence. It is required in microgram quantities and is toxic at modest multiples of the requirement, which is why it is traded as a standardised carrier dilution rather than as the pure salt.
Specifying the grade+
State the declared selenium concentration and carrier your matrix assumes, and the maximum permitted dietary selenium for the species and jurisdiction you are formulating for. Dosing accuracy and mixer homogeneity are part of the specification for this material.
Documentation and specification+
Feed grade material is quoted against the specification your mill or premix formulation requires. Allzone confirms grade, declared content, physical form and any carrier or coating with the supplier before quoting, and shares the technical data sheet and safety data sheet for the exact material offered.
Frequently asked questions
Why is selenium supplied as a dilution?+
The margin between requirement and excess is narrow, so a standardised carrier dilution is used for safe and accurate dosing.
Is this quoted as feed grade material?+
Yes. Feed grade is quoted as a separate specification from food or technical grade, with its own documentation for the exact material offered.
What packaging is available?+
Packaging is confirmed with the supplier at quotation for the grade and quantity discussed.
Can you deliver to feed mills across Canada?+
Yes. LTL and FTL freight is arranged across Ontario, Quebec and Western Canada, with container-direct supply for repeat volumes.
