Market
In Switzerland, aluminium-silicate-type food additives are governed by the Swiss positive list system under the Zusatzstoffverordnung (ZuV), where only listed additives may be used and must follow the application list and purity rules. As of the BLV ZuV Annex 1a (in force 1 July 2025), sodium aluminium silicate (E 554) and potassium aluminium silicate (E 555) are listed as permitted additives, while aluminium silicate (kaolin, E 559) is not listed. The Swiss application list (ZuV Annex 3B, in force 1 July 2025) shows a specific permitted case for E 554 in cooking salt used for surface treatment of ripened cheese, with a maximum expressed as aluminium. Market access therefore depends critically on the exact E-number identity (e.g., E 554 vs. E 559) and the intended Swiss food-category use conditions.
Market RoleImport-dependent regulatory end-use market (food manufacturing ingredient market; authorization depends on Swiss positive lists)
Domestic RoleSpecialty food-manufacturing input used in narrowly defined applications under Swiss additive rules
Risks
Regulatory Compliance HighMisclassification or mislabeling of the aluminium-silicate ingredient can block Swiss market access: aluminium silicate (kaolin, E 559) is not listed in the Swiss BLV ZuV Annex 1a (in force 1 July 2025), while E 554/E 555 are listed, and EU rules deleted E 559 from the Union list after 31 January 2014—creating a high risk of non-compliance if the product is supplied/marketed as E 559 for food-additive use.Confirm the exact additive identity and intended technological function (e.g., E 554 vs. E 555 vs. E 559), map to the Swiss ZuV positive list and Annex 3B use conditions before contracting, and seek FSVO/BLV clarification/authorization route if not listed.
Regulatory Compliance MediumEven when E 554 is used, Swiss permissions can be narrowly defined by food category and expression basis (e.g., a limit calculated as aluminium and framed as residual content in cheese for a specific cheese-related salt application), increasing the risk of non-compliant downstream use outside the allowed scenario.Contractually restrict use to the Swiss-permitted food category/use case, and verify customer formulations and labeling against ZuV Annex 3B conditions and expression basis (calculated as aluminium).
Food Safety MediumAluminium exposure from aluminium-containing additives is a recognized regulatory concern in Europe; EFSA exposure work includes aluminium-containing additives such as E 554, and EFSA’s re-evaluation of E 554/E 555 identified potential exceedance of the tolerable weekly intake for aluminium in exposure scenarios and noted data gaps for safety assessment, which can drive tighter controls or buyer restrictions.Provide robust compositional characterization and batch testing (including aluminium-related metrics and relevant contaminants), and monitor EU/Swiss updates that may change permitted uses or maximum levels.
Logistics MediumAs a landlocked market, Switzerland is exposed to disruptions in European port-to-inland corridors (rail/truck capacity, strikes, border congestion), which can delay delivery of bulk mineral additive inputs and disrupt manufacturing schedules.Hold safety stock in-region (EU/CH) and use dual logistics routings (alternate ports/corridors) for continuity.
Sustainability- Upstream mineral extraction/processing impacts (energy, land disturbance) occur largely outside Switzerland; Swiss buyers may require supplier due diligence for responsible sourcing.
Labor & Social- Upstream mining and mineral processing labor conditions are a supplier-country risk rather than Switzerland-specific; Swiss importers may need due diligence documentation depending on buyer requirements.
FAQ
Is aluminium silicate (kaolin, E 559) permitted as a food additive in Switzerland?Not as a listed food additive in the Swiss BLV ZuV Annex 1a (in force 1 July 2025): the annex lists E 554 (sodium aluminium silicate) and E 555 (potassium aluminium silicate), but does not list E 559 (aluminium silicate/kaolin). In the EU, E 559 was also deleted from the Union list after 31 January 2014.
What is one documented Swiss permitted use case for sodium aluminium silicate (E 554)?In the Swiss BLV ZuV Annex 3B application list (in force 1 July 2025), E 554 is permitted for cooking salt used for the surface treatment of ripened cheese (food category 01.7.2), with a maximum of 20 mg/kg (or mg/l) calculated as aluminium, expressed as residual content in cheese.
Do food imports into Switzerland require certification by default?The FSVO/BLV states that foodstuffs may be imported into Switzerland without certification, while importers must ensure compliance with Swiss food law through self-inspection; special provisions apply for certain categories (notably foods of animal origin from third countries) and specific cases.
