Censil is a FAMI-QS certified precipitated silica manufacturer for feed & food applications. Full certification scope covers 13 silica grades. Audit reports available. Trusted by global feed additive companies.
Censil is a FAMI-QS certified precipitated silica manufacturer based in Fujian, China. With FAMI-QS Certificate No. CNBJ380053-CN — audited by Bureau Veritas and valid through March 2027 — Censil is among the very few FAMI-QS certified silica manufacturers in China, serving feed mills, premix companies, and animal nutrition distributors in over 40 countries.
All 13 grades of Censil feed grade precipitated silica are produced under the FAMI-QS certified quality management system, ensuring every shipment meets international feed safety standards including EU Regulation (EC) No 183/2005 and Directive 2002/32/EC.
FAMI-QS (Feed and Food Safety Assurance Scheme) is the world's leading certification scheme for feed safety, recognized by the European Commission as the standard for feed ingredient manufacturing. For feed grade precipitated silica, FAMI-QS certification verifies:
For feed additive purchasers, sourcing from a FAMI-QS certified silica manufacturer is increasingly a mandatory requirement — not just a preference. Major feed companies in Europe, Asia, and Latin America require their silica suppliers to hold FAMI-QS certification as a condition of supply.

Feed additive manufacturers often ask how FAMI-QS compares to other food and feed safety certifications. Here is how they differ:
| Feature | FAMI-QS | HACCP | ISO 22000 | FDA 21 CFR | REACH |
|---|---|---|---|---|---|
| Feed-Specific | ✅ Yes | ❌ Generic | ❌ Generic | ❌ US-only | ❌ EU chemical |
| EU Recognized | ✅ EC 183/2005 | ❌ No | ❌ No | ❌ No | ❌ No |
| Independent Audit | ✅ Annual | ❌ Self | ✅ 3-year cycle | ❌ Registration | ❌ Registration |
| GMP Required | ✅ Yes | ❌ No | ❌ No | ✅ Yes | ❌ No |
| Required by Major Feed Cos | ✅ Increasingly | Often | Sometimes | US market only | EU market only |
Key Takeaway: FAMI-QS is the only feed-specific, globally recognized certification that combines GMP, independent auditing, and EU regulatory endorsement. For feed grade silica FAMI-QS compliance, this certification is the gold standard that major feed companies increasingly require from their silica suppliers.
All 13 grades of Censil feed grade precipitated silica are covered under the FAMI-QS certification:
| Category | Grades | BET Range | Primary Use |
|---|---|---|---|
| Powder (7 grades) | P-160, P-180, P-200, P-220, P-250, P-280, P-300 | 160-310 m²/g | Carrier, anti-caking, free-flow agent |
| Micropearl (5 grades) | MP-160, MP-180, MP-200, MP-230, MP-250 | 160-270 m²/g | Low-dust carrier, automated feed lines |
| Hydrophobic (1 grade) | Censil D17 | ≥160 m²/g | Moisture-resistant anti-caking |
Censil FAMI-QS certified precipitated silica complies with all applicable regulations for use as a feed additive (E 551 — silicon dioxide):
When sourcing feed grade precipitated silica for the European market, FAMI-QS certification combined with EU E 551 compliance is essential. Censil's certification ensures full regulatory compliance for feed companies importing feed grade silica FAMI-QS certified products from China.
Yes. Censil holds FAMI-QS certification (Certificate No. CNBJ380053-CN), issued by Bureau Veritas and valid through March 2027. Censil is one of the few FAMI-QS certified precipitated silica manufacturers in China, covering all 13 feed grade products.
FAMI-QS (Feed and Food Safety Assurance Scheme) is the globally recognized certification for feed safety, endorsed by the European Commission. For feed grade silica FAMI-QS certification means the manufacturer has implemented a complete Feed Safety Quality Management System including GMP, independent auditing, and contaminant control — ensuring the silica is safe for use in animal feed.
Among Chinese precipitated silica manufacturers, only a few hold FAMI-QS certification. Censil (Longyan Shenghe Chemical, Certificate No. CNBJ380053-CN) is one of the few FAMI-QS certified silica manufacturers in China. This limited availability makes FAMI-QS certified Chinese suppliers particularly valuable for international feed companies seeking certified silica at competitive prices.
For feed grade precipitated silica used as a feed additive, FAMI-QS certification means the manufacturer meets the strictest international standards for feed safety. This includes GMP (Good Manufacturing Practice), annual independent audits by accredited bodies (Bureau Veritas for Censil), and compliance with EU Regulation (EC) No 183/2005 on feed hygiene and Directive 2002/32/EC on contaminant limits.
Both Censil and Evonik SIPERNAT hold FAMI-QS certification. The key difference is that Evonik embeds FAMI-QS information in PDF documents and technical data sheets, while Censil makes its FAMI-QS certified precipitated silica status prominently available on its website. In terms of product quality, Censil matches SIPERNAT in key specifications (SiO₂ ≥98%, BET 160-310 m²/g) while offering 30-45% cost savings as a China-based FAMI-QS certified silica manufacturer.
