Market
Calcium aluminium silicate (INS 556) is a mineral-based anti-caking agent used to keep powder products free-flowing in industrial food manufacturing. In Vietnam, market access is driven primarily by regulatory permissibility and compliance with the Ministry of Health framework for food additives (notably Circular 24/2019/TT-BYT) and product declaration rules under Decree 15/2018/ND-CP. It is typically procured B2B by importers and ingredient distributors supplying domestic processors that manufacture dry mixes such as food-grade salt and seasoning powders. Codex references identify the additive and its function, but Codex GSFA online indicates there are no Codex GSFA provisions for INS 556, increasing the importance of verifying Vietnam’s permitted-list and use-level conditions case-by-case.
Market RoleImport-dependent food additive/ingredient market serving domestic food processing
Domestic RoleIndustrial anti-caking agent input used by domestic manufacturers of dry powder foods (e.g., salt and seasoning blends) subject to Vietnam food additive controls
Risks
Regulatory Compliance HighMarket access can be blocked if the additive is not confirmed as permitted for the intended food group/use conditions under Vietnam’s food additive framework (Circular 24/2019/TT-BYT), or if a required declaration-registration route is missed for additives not on the permitted list; this can trigger suspension from circulation or mandatory corrective actions.Before shipment, map the intended end-use food group(s) to Circular 24/2019 appendices and confirm whether self-declaration is sufficient or whether declaration registration with the Vietnam Food Administration is required; align contracts to include compliance documentation deliverables.
Documentation Gap MediumProduct declaration in Vietnam can fail or be delayed if the dossier lacks valid food-safety test results/data sheets (within the required timeframe and from an appropriate laboratory), or if supporting documents do not match product identity/labeling.Prepare the Decree 15/2018/ND-CP self-declaration package early, ensure test reports are within the validity window, and run a pre-import document reconciliation (name, INS/CAS identifiers, lot numbers, pack sizes).
Food Safety MediumAs a mineral-derived additive, quality risk is concentrated in contamination controls (e.g., heavy metals) and supplier-specification integrity; downstream buyers may reject lots that fail internal specifications or regulatory expectations.Require lot-specific COA aligned to a recognized specification basis, and validate via independent testing when onboarding suppliers or when risk flags arise.
Public Health MediumBuyer and regulator scrutiny can increase for aluminium-containing additive families due to dietary aluminium exposure concerns; risk management expectations may tighten even when the additive is technically permitted.Minimize use to the technically necessary level, document functional need, and ensure exposure management aligns with buyer requirements and relevant safety evaluations for aluminium in foods.
Logistics LowMoisture ingress during ocean transport or warehouse storage can degrade performance (caking, loss of flowability) and lead to downstream processing issues or claims.Use moisture-barrier packaging, desiccants where appropriate, and humidity-controlled storage with FIFO and seal-integrity checks at receipt.
FAQ
What is the international identification number for calcium aluminium silicate used as a food additive?It is listed as INS 556 (calcium aluminium silicate / calcium aluminosilicate) in the WHO JECFA food additives database.
What is the primary technical function of calcium aluminium silicate in foods?It is used as an anti-caking agent to help powdered products remain free-flowing, as reflected in Codex/FAO and WHO/JECFA additive listings.
Which Vietnam legal instruments are central for placing a food additive like calcium aluminium silicate on the Vietnamese market?Vietnam’s Ministry of Health Circular 24/2019/TT-BYT provides the framework for permitted food additives and their management, and Decree 15/2018/ND-CP sets out product self-declaration procedures that apply to food additives before market circulation.
If the additive is repacked or portioned in Vietnam, is there a specific compliance point to watch?Yes. Circular 24/2019/TT-BYT includes specific requirements for portioning/repacking, including obtaining written consent from the producer or responsible entity and ensuring labeling reflects the repacking/portioning date when applicable.
