Food-grade calcium sulfate (INS 516 / E516) is regulated in Vietnam as a food additive under the Ministry of Health’s food safety framework, including Circular 24/2019/TT-BYT and Decree 15/2018/ND-CP. Vietnam’s market role for this item is primarily demand-side, serving domestic food manufacturers that use permitted additives within specified food categories and GMP/max-level rules. The most material operational constraint for suppliers is regulatory compliance: ensuring the additive is permitted for intended foods and completing required product declaration/self-declaration documentation supported by up-to-date test results. As a bulky, low-value mineral powder, the supply route is typically sea-freight oriented and exposed to freight volatility and port delays.
Market RoleImport-dependent consumer market for food-grade calcium sulfate used by domestic food manufacturers
Domestic RoleInput additive for domestic food processing (e.g., flour-based products, dairy/cream products, and other permitted categories under Vietnam’s food additive rules)

Risks
Regulatory Compliance HighFailure to align calcium sulfate (INS 516) with Vietnam’s permitted additive rules and product declaration/self-declaration requirements (including current test documentation and Vietnamese-language compliance materials) can block lawful market distribution and trigger clearance delays, administrative enforcement, or product withdrawal.Confirm the intended use is permitted under Circular 24/2019/TT-BYT (as amended/consolidated where applicable), prepare the Decree 15/2018/ND-CP self-declaration/registration dossier, and ensure batch COA + compliant test results are available and consistent with the declared specification.
Food Safety MediumNon-food-grade or contaminated calcium sulfate (e.g., inappropriate gypsum sources) may fail impurity limits and purity specifications (e.g., heavy metals/fluoride controls), creating rejection, recall, or enforcement risk in Vietnam’s food safety system.Procure only food-grade material with COA aligned to JECFA specifications for calcium sulfate (INS 516) and verify via independent laboratory testing when onboarding suppliers or changing sources.
Logistics MediumAs a bulky, low-value powder typically moved by sea, supply is exposed to freight-rate volatility and shipping disruptions that can materially affect landed cost and production continuity for Vietnam-based food manufacturers.Use dual sourcing across origins, lock freight capacity where possible, and keep contingency inventory at importer warehouses for critical customers.
Regulatory Change MediumVietnam’s food safety and additive rules are periodically amended (including updates affecting Circular 24/2019/TT-BYT), which can change compliance expectations, documentation practice, or permitted-use conditions over time.Monitor Ministry of Health/Vietnam Food Administration updates and maintain a compliance change-log tied to product declarations and customer specifications.
Sustainability- Mineral sourcing transparency: ensure traceability to an appropriate food-grade supply chain (not construction/industrial gypsum streams) to reduce contamination and compliance risk.
- Waste and dust management at handling sites (ports/warehouses) due to fine powder characteristics.
FAQ
Is calcium sulfate (INS 516 / E516) a recognized food additive in Vietnam?Vietnam’s Ministry of Health regulates food additives through Circular 24/2019/TT-BYT, which issues the list of permitted food additives and rules for their use and management. Calcium sulfate is recognized internationally as INS 516 and is included in the permitted-additive framework that Vietnam aligns with under this circular.
What is a key Vietnam compliance step before a food additive like calcium sulfate can be sold on the market?Decree 15/2018/ND-CP establishes product self-declaration requirements for many pre-packaged foods and food additives. A typical dossier includes a self-declaration form and a food safety test result sheet issued within the required timeframe by a designated laboratory or a laboratory meeting ISO 17025 conditions, and the documentation must be suitable for submission and posting as required by the decree.
What specifications should buyers request for food-grade calcium sulfate used as a food additive?A practical baseline is conformance to the JECFA specification for calcium sulfate (INS 516), supported by a batch Certificate of Analysis. JECFA’s monograph describes the material and includes key purity expectations such as minimum assay after drying and limits for selected contaminants (e.g., lead and fluoride), which can be used as acceptance criteria.
