Why This Article Exists
If you’re sourcing feed-grade gluconate from China for animal nutrition formulations, you’ve probably noticed two things. First, almost every supplier advertises ISO 22000 or HACCP and calls it a day. Second, when you ask specifically about FAMI-QS — the European feed industry’s dedicated certification scheme — most suppliers either go quiet or claim it without documentation. This article is written by a Shandong-based gluconate manufacturer that is currently in the FAMI-QS application process, and we explain exactly what feed buyers should expect, ask, and verify when sourcing from Chinese producers.
The article is organized in two halves. The first half is for procurement: specifications, packaging, MOQ, shipping. The second half is for compliance and quality assurance: FAMI-QS application status, supply chain transparency, audit readiness, and what FEFAC’s framework actually requires.
The Feed-Grade Gluconate Landscape, Briefly
Gluconate-family compounds — sodium gluconate, calcium gluconate, ferrous gluconate, zinc gluconate, magnesium gluconate, potassium gluconate, and copper gluconate — are widely used in animal feed for three primary functions: chelated mineral supplementation (improving bioavailability of zinc, iron, copper, and other trace elements), pH and buffering control in feed processing, and palatability enhancement in pet food and aquaculture feeds.
The global feed additives market is increasingly bifurcated. On one side, European and North American buyers are tightening compliance requirements as EU Regulation 183/2005 on feed hygiene is enforced more rigorously and as customers downstream (pet food brands, aquaculture operators, integrators) demand documented traceability. On the other side, the majority of low-cost suppliers in Asia continue to operate without specialty feed-grade certifications, relying on general ISO 9001 quality management as a proxy.
This gap creates a real procurement problem. Feed-grade gluconate from a non-certified supplier is technically usable, but it may fail your customer’s audit, fail import-country compliance review, or — worse — introduce contamination risk that ISO 9001 alone is not designed to catch.
Part 1: What Procurement Should Know
Product Family and Grade Specifications
WIS Biotech (Shandong Wisdomesty Biotech Co., Ltd.) manufactures the following feed-grade gluconate products at its Shanghe County, Jinan facility:
| Product | CAS No. | Typical Assay | Primary Feed Function |

All products are white to off-white powders, water-soluble, with specifications aligned to EU feed additive purity requirements. Detailed Certificates of Analysis (COA), Material Safety Data Sheets (MSDS), and Technical Data Sheets are available on request via the individual product pages linked above.
Packaging and Logistics
Standard packaging is 25 kg PE-lined kraft paper bags, palletized for ocean freight. Custom packaging (drums, super sacks, branded bags) is available for orders meeting minimum quantity thresholds.
For international orders, the manufacturing facility produces under WIS Biotech, while export documentation, contract execution, and shipping are handled by the group’s international trading entity, Definly Chemicals (registered legal name: Shandong Definly Chemical Co., Ltd.). This arrangement is detailed in our group structure page. The practical effect for buyers: a single commercial counterparty (Definly Chemicals) handles invoicing, payment terms, and shipping coordination, while production accountability remains with the WIS Biotech facility under direct factory oversight.
MOQ and Pricing Notes
Minimum order quantity for individual gluconate products is typically 1 metric ton per grade, with mixed-product 20′ container orders accommodating smaller per-item quantities. Pricing is quoted FOB Qingdao for most destinations, with CIF options available for India (Nhava Sheva, Mundra), Southeast Asia, and select European ports. Form E (China-ASEAN preferential origin certification) is provided for Southeast Asian shipments where applicable.
Combined gluconate production capacity at the Shanghe facility is approximately 60,000 metric tons per year across the full product family, which allows us to accept both spot orders and annual contract volumes for established customers.
Part 2: What Compliance and QA Should Know
The FAMI-QS Application: Where We Stand
WIS Biotech is currently in the documentation preparation phase of FAMI-QS application, with audit conducted under the framework of the European Feed Manufacturers’ Federation (FEFAC) — the organization that owns and maintains the FAMI-QS certification scheme. Our target timeline is full certification within six months from the date of this article.
We disclose application status rather than waiting for the certificate because we believe transparency is more valuable than a marketing-friendly silence. Three reasons:
- Buyers conducting due diligence ask the question directly. Telling you we are in application is verifiable; claiming certification we do not hold is not.
- FAMI-QS application is not trivial. The documentation phase requires HACCP analysis specific to feed safety, Feed Fraud Prevention and Defence procedures (mandatory since FAMI-QS Version 6, 2018), supplier qualification systems, and traceability protocols. We have been preparing this documentation since early 2026 and welcome procurement audits of our current state.
- Procurement timelines align. If you are evaluating suppliers for 2026 H2 or 2027 contracts, our certification will be in place before your shipment date. Including a “FAMI-QS by Q4 2026” supplier in your sourcing pool today is a reasonable risk position.
What FAMI-QS Actually Requires
FAMI-QS is the only globally recognized certification scheme designed specifically for specialty feed ingredients and their mixtures. It is built on:
- EU Regulation 183/2005 on feed hygiene (the legal foundation for feed safety in the European Union)
- HACCP principles (Hazard Analysis and Critical Control Points)
- Codex Alimentarius standards for food safety, adapted to feed
- Feed Fraud Prevention and Defence requirements (mandatory module since 2018)
The certification covers the full chain: raw material qualification, production, processing, storage, transportation, and trading. Audits are conducted by FAMI-QS-authorized third-party certification bodies (commonly LRQA, SGS, Bureau Veritas, DNV, or Cotecna). Initial certification is valid for three years, with annual surveillance audits and at least one unannounced audit during the validity period.
Critically, FAMI-QS is not interchangeable with general food safety certifications like ISO 22000 or FSSC 22000. While there is overlap, FAMI-QS includes feed-industry-specific requirements (cross-contamination protocols for medicated vs. non-medicated feed handling, undesirable substance limits per EU 2002/32/EC, carryover thresholds) that ISO 22000 does not cover in depth.
Our Current Compliance Stack
While FAMI-QS is in application, WIS Biotech and its group partner Definly Chemicals already maintain the following certifications. The split between manufacturing-side and trade-side certifications reflects the group’s two-entity structure:
| Certification | Held By | Status | Relevance to Feed Buyers |
|---|---|---|---|
| FAMI-QS | WIS Biotech (factory) | In application (FEFAC-administered scheme) | Target certification; expected within 6 months |
| FSSC 22000 | WIS Biotech (factory) | In application | Food safety baseline; required by many premium feed buyers |
| ISO 9001 | Definly Chemicals (export entity) | Certified | Quality management system covering trade and documentation |
| ISO 14001 | Definly Chemicals | Certified | Environmental management; relevant for ESG-focused buyers |
| ISO 45001 | Definly Chemicals | Certified | Occupational health & safety management |
| EcoVadis Silver | Definly Chemicals | Awarded (top 25% globally) | ESG rating; required by many EU enterprise procurement |
| REACH Registration | Definly Chemicals | Registered | EU chemical compliance for import legality |
| Halal (IFANCA, USA) | Definly Chemicals | Certified | Halal-compliant feed production |
| Kosher (Orthodox Union / OU) | Definly Chemicals | Certified | Kosher-compliant feed production |
| Greenhouse Gas Verification | Definly Chemicals | Verified | Carbon accounting; aligned with EU CBAM |
Cross-Contamination and Feed Safety Protocols
Our Shanghe facility is dedicated to gluconate and mineral salt production. We do not manufacture medicated feed additives, antibiotics, or veterinary pharmaceuticals on the same premises. This eliminates the most common cross-contamination concern in shared-facility feed production. Production lines for different gluconate grades are separated by cleaning protocols compliant with ISO 22002-1:2009 Clause 10 (prerequisite programs for food safety, applicable to feed under the FAMI-QS framework).
We do not produce or claim pharmaceutical grade, GMP-certified, FDA-registered, GRAS, or USP/BP/FCC grade gluconate. Our scope is strictly food-grade and feed-grade, which is reflected in our compliance strategy and certifications targeted.
Supply Chain Transparency
Raw materials for gluconate production are sourced from qualified suppliers within China, with full traceability from raw material lot to finished product batch. Glucose feedstock is sourced from corn starch processors with relevant food-grade certifications. Each finished product batch carries a unique COA referencing input lot numbers, production date, and analytical results.
For audit-grade documentation, we provide:
- Batch-specific Certificates of Analysis (COA) with full analytical results
- Material Safety Data Sheets (MSDS) compliant with REACH
- Specification sheets aligned with EU feed additive purity criteria
- Production process flow documentation under NDA
- Facility audit access (advance arrangement required)
Frequently Asked Questions
Is feed-grade gluconate the same as food-grade gluconate?
Chemically the two grades can be identical in purity and form. The difference lies in production controls, documentation, and intended use. Feed-grade gluconate is produced under feed safety management systems such as FAMI-QS, with traceability and cross-contamination controls specifically designed for the animal feed supply chain. Food-grade gluconate follows food-industry frameworks like FSSC 22000 or HACCP. A supplier producing both grades on the same line must demonstrate clear segregation protocols.
What is FAMI-QS and why does it matter for feed buyers?
FAMI-QS (Feed Additive and Pre Mixture Quality System) is a certification scheme established under the framework of EU Regulation 183/2005 on feed hygiene, owned and administered by the European Feed Manufacturers’ Federation (FEFAC). It is the only globally recognized certification specifically targeting specialty feed ingredients and premixtures. For feed buyers, FAMI-QS certification of a supplier provides documented assurance of HACCP-based hazard analysis, feed fraud prevention, supply chain traceability, and ongoing audit oversight. Over 1,000 facilities in more than 50 countries are FAMI-QS certified.
Does WIS Biotech currently hold FAMI-QS certification?
No. WIS Biotech is currently in the documentation preparation phase of FAMI-QS application, with a target completion timeline of approximately six months from May 2026. We disclose application status transparently because we believe transparent communication of compliance posture is more valuable to buyers than ambiguity. Audit-ready documentation, current compliance certifications (ISO 9001/14001/45001, EcoVadis Silver, Halal, Kosher, REACH), and facility access are available for buyer due diligence today.
Which entity will hold the FAMI-QS certificate — WIS Biotech or Definly Chemicals?
FAMI-QS is a production-side certification and will be held by Shandong Wisdomesty Biotech Co., Ltd. (the manufacturing entity at the Shanghe facility), not by Definly Chemicals (the export and trading entity). This reflects the group’s structure: production-side certifications belong to the factory, while trade-side certifications such as ISO 9001, EcoVadis, REACH, Halal, and Kosher are held by Definly Chemicals. Buyers receive integrated commercial documentation from Definly Chemicals while production accountability remains with the WIS Biotech facility.
What gluconate products are available in feed-grade specification?
WIS Biotech manufactures feed-grade calcium gluconate, ferrous gluconate, zinc gluconate, magnesium gluconate, potassium gluconate, and copper gluconate at the Shanghe County facility in Shandong, China. Sodium gluconate is available in industrial and food grades but not in feed grade. Combined gluconate production capacity is approximately 60,000 metric tons per year.
What is the minimum order quantity for feed-grade gluconate?
Minimum order quantity for individual feed-grade gluconate products is typically 1 metric ton per grade. Mixed-product 20-foot container orders are accommodated for smaller per-item quantities. For trial samples, we can arrange smaller shipments under specific conditions. Contract pricing for annual volumes is available for qualified buyers.
Can you ship to the European Union, and what compliance documentation is included?
Yes. Definly Chemicals, the group’s export entity, is REACH registered for relevant chemical products and provides EU-compliant import documentation. Standard documentation includes Certificate of Analysis, Material Safety Data Sheet (REACH-compliant), commercial invoice, packing list, certificate of origin, and Bill of Lading. Additional documentation such as health certificates can be arranged based on destination requirements.
How can I verify your facility before placing an order?
Several verification options are available. Site visits to the Shanghe County facility can be arranged in advance. Facility photographs and operational details are published on wis-biotech.com. Documentation packages for buyer due diligence, including current certifications and FAMI-QS application status, are available under NDA. Commercial references from existing customers can be provided on request. The facility address is publicly listed at No. 1226, Yuhuang West Road, Yuhuangmiao Town, Shanghe County, Jinan, Shandong, China.
How is your supplier different from a trading company on Alibaba or Made-in-China?
WIS Biotech is the manufacturer, not a re-seller or trading company. Production occurs at our owned facility in Shanghe County. International commercial functions are handled by our group’s export entity, Definly Chemicals, registered in Jinan, Shandong. This two-entity structure is standard in Chinese chemical exports and is documented on our group structure page. Buyers contracting with Definly Chemicals contract with a single commercial counterparty backed by direct production capacity.
When you say “FAMI-QS in application,” what is the actual current status?
We are in the documentation preparation phase, which involves completing HACCP analysis specific to feed safety, Feed Fraud Prevention and Defence procedures, supplier qualification documentation, and traceability protocols. The next phase will be application submission to the FAMI-QS Secretariat, followed by certification body audit (initial certification audit). Total timeline from initial application submission to certificate issuance typically takes three to six months for a well-prepared facility, depending on certification body scheduling. Our target is full certification within six months of this article’s publication date.
