Market
Amorphous silicon dioxide (INS 551 / E551) is permitted under Singapore’s Food Regulations as a food additive and is commonly used for technological functions in dry food applications. Singapore primarily functions as an import-dependent ingredient market, supplying local food and supplement manufacturers and distributors. Market access is driven by strict compliance with SFA’s permitted additive listing and conditions of use, supported by supplier documentation and batch testing where appropriate. Imports must follow Singapore Customs permit and tax requirements, and SFA oversight includes regulatory limits and compliance monitoring for foods sold in Singapore.
Market RoleImport-dependent ingredient market and regional distribution hub
Domestic RoleRegulated processing aid/food additive input for imported and locally manufactured foods sold in Singapore, especially dry mixes where anti-caking performance is needed
Risks
Regulatory Compliance HighIf amorphous silicon dioxide (INS 551) is used outside SFA’s permitted additive framework (e.g., not permitted for the intended product category, or not meeting applicable conditions/maximum levels under the Food Regulations), the affected food products may be blocked from import/sale and trigger enforcement actions or recalls.Verify INS 551 is permitted for the intended use via SFA resources, align formulation to the Food Regulations, and maintain a defensible compliance file (specification, CoA, and change-control records).
Food Safety MediumNon-conformance to recognized specifications (identity/purity/impurity controls) can create contamination risk and lead to rejections, withdrawals, or customer audit failures in Singapore’s compliance-focused market.Require supplier CoA against JECFA specifications, conduct periodic third-party testing for key impurities, and qualify suppliers with robust quality systems.
Documentation Gap MediumIncorrect HS classification or permit declaration errors can delay clearance and may trigger penalties under Singapore’s import control framework.Pre-validate HS code/permit requirements, use a standardized import document checklist, and apply internal review for first-time suppliers and new SKUs.
Logistics LowShort-notice production or shipping disruptions can interrupt supply for just-in-time manufacturers, especially when urgent replenishment shifts from sea freight to higher-cost air freight.Maintain safety stock for critical formulations and dual-source approved suppliers where feasible.
Sustainability- Upstream industrial mineral/chemical footprint is largely offshore (silica raw materials and energy-intensive processing); downstream buyers may request ESG and responsible sourcing documentation for supplier qualification.
Labor & Social- Powder handling worker-safety controls (dust management, PPE, and safe handling procedures) across manufacturing, warehousing, and downstream blending operations.
Standards- HACCP (supplier facility and/or downstream manufacturer)
- GMP (supplier facility and/or downstream manufacturer)
FAQ
Is amorphous silicon dioxide (INS 551 / E551) permitted for use in foods sold in Singapore?Yes. SFA’s published guidance list of food additives permitted under the Singapore Food Regulations includes INS 551 (Silicon dioxide, amorphous). You should still verify the intended use conditions and any applicable maximum levels under the Food Regulations using SFA’s resources.
What does silicon dioxide (INS 551) do in food products?Codex GSFA lists amorphous silicon dioxide (INS 551) as functioning as an anti-caking agent, antifoaming agent, and carrier, with provisions across multiple dry and powdered food categories.
What are the main import-compliance checkpoints in Singapore for food ingredients/additives like INS 551?Key checkpoints include: ensuring the additive is permitted and used within SFA’s Food Regulations; preparing documentation such as invoices/packing lists and quality specifications/CoA for buyer and regulator expectations; and obtaining the required Singapore Customs import permit and accounting for GST/duty as applicable.
