Sodium Butyrate for Feed: Assay, Coating and Supplier Checklist
Sodium Butyrate for Feed: Assay, Coating and Supplier Checklist
To compare sodium butyrate products for feed, buyers must understand what the assay represents, whether the product is coated or carried, which other components are present, and how the batch COA supports the declared composition. A quotation based only on price per tonne can be misleading because pure, uncoated, coated and carrier-based commercial products may deliver different quantities of declared sodium butyrate and may behave differently in storage, dosing and feed manufacture.
Confirm the chemical identity and the commercial product
Public chemical references identify sodium butyrate as CAS 156-54-7 with the formula C4H7NaO2. That chemical identity is only the starting point. A commercial feed product may be an uncoated powder, a coated or encapsulated product, or a preparation containing sodium butyrate with a carrier or coating material.
The buyer should ask the supplier to state the full commercial composition. “Sodium butyrate 70%,” for example, is incomplete unless the document explains the reporting basis and the remaining components. Do not assume that every number describes the same active basis or that every coating has the same purpose or release behavior.
The TDS, specification, COA, SDS, label and quotation should use consistent product identity and composition language. If the offered product is intended for feed, the supplier should describe only the animal categories and destination markets supported by the exact product’s current regulatory documentation.
Understand assay basis before comparing price
Ask how sodium butyrate content is determined and reported. Important questions include:
- Is the result stated as sodium butyrate itself, another chemical equivalent or a calculated active content?
- Is it reported on an as-is or dry basis?
- Does the stated percentage include or exclude a coating or carrier?
- Which method is used and what is its routine precision?
- Is every batch tested, or is part of the result calculated from formulation and verified periodically?
The contract and COA should use the same basis. If two suppliers quote different assays or product formats, compare the cost per kilogram of verified declared sodium butyrate, then add freight, packaging, handling and process costs. This is still not a complete performance comparison; the buyer must also validate the product in the intended feed process.
Evaluate coated and uncoated products as different formulations
Coating can change physical handling and release characteristics, but the word “coated” does not define a standard performance. Ask the supplier to identify:
- coating or carrier type and declared proportion, where disclosable and required;
- particle-size or granule information relevant to mixing;
- dust, flow and caking controls;
- stability data and storage conditions for the exact product;
- method used to support any release or protection claim;
- manufacturing consistency and change-notification process.
Do not publish claims such as “targeted intestinal release,” “repair rate” or a numerical antimicrobial effect without a clearly identified product, test method, conditions, independent review and applicable legal basis. A laboratory result, if valid, should not be presented as a guaranteed animal outcome.
The feed mill should select product format with its qualified nutrition, quality and production teams. Consider the premix or feed matrix, mixing sequence, conditioning or pelleting conditions, dosing equipment and the destination market’s rules.
Build a product-specific COA checklist
The buyer’s agreed release fields may include the following, depending on the actual product:
- product/grade name and batch number;
- sodium butyrate assay with reporting basis;
- moisture or loss on drying;
- free acid, alkalinity or related control where relevant;
- coating or carrier declaration for a formulated product;
- physical form, particle-size range or bulk density where controlled;
- relevant contaminants or microbiological fields required by the agreed feed specification;
- release date, shelf-life basis and authorization.
This is a checklist, not an ADDEASY specification. The actual fields and limits must be taken from the approved current product documents. A feed buyer should also confirm that analytical units and methods are consistent and that the COA belongs to the lot received.
Qualify handling and feed-mill fit
A plant trial should check receiving, storage, dust control, flow, dosing, mixing and any heat-processing step relevant to the site. Record the product lot, process conditions and acceptance criteria. If the supplier makes a stability or release claim, ask for product-specific evidence and decide whether the buyer needs independent verification.
The current SDS and site risk assessment should guide worker protection and spill response. Odor, dust and hygroscopic behavior, where relevant to the exact commercial product, should be assessed in real packaging and plant conditions rather than assumed from a pure-substance description.
Avoid universal inclusion rates. The appropriate use level depends on the exact product composition, authorized conditions, animal species/category, feed matrix and professional formulation decision.
Check regulatory and documentation status
A substance being known in animal nutrition does not mean every commercial grade can be sold for feed in every country. Ask for the destination-specific product status, label information and documents. The importer should verify registration, authorization, claims, maximum or minimum conditions where applicable and establishment requirements.
Request the current TDS/specification, SDS, representative COA and applicable trade documents. Additional certificates should be listed only if they are current, valid and linked to the relevant site and product.
Compare packaging and delivered cost
Ask for the actual bag or package material, liner, net weight, palletization, lot coding and container-loading plan. Consider moisture protection, seal integrity and storage conditions. For delivered-cost comparison, use the same declared-content basis and include freight, payload, packaging, quality testing and loss or handling risk.
For a trial, define whether the sample is representative of routine production and whether the commercial shipment will use the same product code, composition and manufacturing site. A small sample in a different package should not be treated as proof of full-scale logistics performance.
Use a sodium butyrate supplier checklist
Before approval, confirm:
- exact chemical and commercial product identity;
- coated/uncoated status and full declared composition;
- assay and reporting basis;
- current specification and batch COA fields;
- feed and destination-market document status;
- plant handling and trial results;
- packaging, shelf-life and storage basis;
- traceability and change notification;
- Incoterm, destination, quantity and delivery assumptions;
- complaint, deviation and corrective-action process.
Request Exact Product Composition: review the ADDEASY sodium butyrate product page, then send the intended animals/application, destination, preferred product form, quantity, packaging and document needs through the contact form or to bageyi@addeasygroup.com.
Frequently asked questions
What is the difference between coated and uncoated sodium butyrate?
They are different commercial formats. Coating changes composition and may change handling or release behavior. Compare the exact formulation, assay basis and product-specific evidence.
How should I compare sodium butyrate prices?
First normalize the verified declared sodium butyrate content, then include packaging, freight, plant handling and qualification costs. Do not assume equal biological or process performance.
What belongs on a sodium butyrate COA?
The COA should identify the exact product and batch and report the agreed release fields, units and basis. Coated products need composition terminology consistent with the specification.
Can sodium butyrate feed products be marketed for human oral use?
Do not infer human-use suitability from a feed product or from assay alone. Human food, supplement or pharmaceutical uses have separate product and regulatory requirements.
Can a supplier guarantee animal performance?
A supplier may present appropriately supported product data, but animal outcomes depend on many conditions. Avoid unsupported or absolute performance guarantees.
