| Base stainless steel grade | AISI 304 / EN 1.4301 is a common general-purpose food-contact choice. Typical chemistry is approximately 17.5–20% chromium and 8–10.5% nickel; confirm the exact grade with a material certificate. | Bare stainless steel should satisfy applicable food-contact and sanitary-use requirements. A generic “FDA certificate” is not automatically created by using grade 304. | Assess the material under Article 3 of Regulation (EC) No. 1935/2004 and applicable national requirements because there is no single EU-wide specific measure covering every stainless steel article. | Assess against Sections 30 and 31 of the German Food and Feed Code (LFGB), together with the intended-use test program and applicable German guidance. | Require a heat or batch certificate identifying the steel grade, chemical composition, and traceability reference. |
| Higher corrosion-resistance option | AISI 316 / EN 1.4401 or 1.4404 typically contains about 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. The molybdenum content can improve resistance to chloride-containing foods. | 316 is not automatically “more FDA compliant”; it is a material-selection option with potentially better corrosion resistance in demanding conditions. | Use the same food-contact assessment principles. The grade does not replace migration, sensory, or manufacturing documentation where required. | Use the same LFGB assessment principles. Confirm that all food-contact components, not only the bowl body, are covered. | Consider 316 for frequent contact with salty, acidic, or chloride-rich foods; do not use the grade as the only compliance claim. |
| Surface condition | Food-contact surfaces should be smooth, continuous, cleanable, non-absorbent, and free from pits, flaking, sharp burrs, embedded iron, and visible corrosion. | The FDA Food Code uses performance terms such as smooth, durable, corrosion-resistant, nonabsorbent, and easily cleanable for food-contact surfaces. It is a model code rather than a universal product certificate. | Article 3 requires that materials not transfer constituents in quantities that could endanger health, create unacceptable compositional changes, or cause deterioration of organoleptic properties. | Surface condition should support hygienic use and prevent unacceptable transfer of substances or sensory effects under the intended conditions. | Inspect the rim, base, inner wall, welds, and folded edges under bright light. Reject pitting, rough grinding marks, exposed weld defects, or metallic flakes. |
| Polishing and passivation | Mechanical polishing and, where appropriate, controlled passivation can improve surface cleanliness and corrosion resistance. Passivation is not a substitute for cleaning or testing. | Keep records of the process chemicals, rinsing, drying, and final inspection. Any residual process chemicals must not create a food-contact concern. | Manufacturing should follow documented good manufacturing practices under Regulation (EC) No. 2023/2006. | Document chemicals, process controls, rinsing, and verification of the finished food-contact surface. | Request a process specification and visual inspection report; verify that no acid residue, abrasive residue, or free-iron contamination remains. |
| Welded joints and seams | Welds should be continuous where needed, properly finished, free from cracks and crevices, and resistant to corrosion. Internal crevices can retain food soil. | Evaluate the finished surface against applicable sanitary-use requirements rather than relying only on the welding method. | Include weld zones in the Article 3 risk assessment and any migration or corrosion evaluation. | Include weld zones in LFGB testing or technical evaluation when they are part of the food-contact surface. | Check weld uniformity, smoothness, discoloration, pinholes, sharp edges, and cleanability after repeated washing. |
| Rim, rolled edge, and base | The rim should be smooth and safe to handle. A sealed or hygienically designed base should prevent water and food residue from becoming trapped. | Food-contact and user-safety evaluation should cover the complete finished article, including folded edges and attached bases. | All permanently attached parts must be included in the overall compliance assessment and traceability system. | All food-contact parts and possible extractable substances must be considered under the intended-use assessment. | Run edge-pressure, cut-risk, cleanability, and water-retention checks on production samples. |
| Coatings, markings, and decorative layers | Prefer uncoated stainless steel on the food-contact side. If coatings, printing, labels, or colored interiors are used, they require separate food-contact evaluation. | Do not extend a bare-metal claim to coatings, inks, adhesives, or painted surfaces. Each food-contact component needs its own regulatory basis. | Coatings and printed layers must comply with Article 3 and be manufactured under Regulation (EC) No. 2023/2006; supplier declarations and test evidence should be available. | Coatings, inks, adhesives, and decorative layers should be included in the LFGB assessment and sensory testing where relevant. | Request a component list showing every food-contact and potentially migrating material, including adhesive labels and printed graduations. |
| Silicone or plastic accessories | Lids, seals, non-slip rings, handles, and spatulas are separate food-contact materials and may be more critical than the steel bowl. | Request the applicable FDA regulatory basis for each polymer or elastomer component; do not accept a steel-only declaration for the complete set. | Assess each material and its intended temperature, food type, and contact time under the applicable EU framework. | Include each accessory in the LFGB test scope, especially silicone seals and soft-touch components. | Match the declaration, test report, material, color, and production version to the actual supplied accessories. |
| Overall food-contact safety principle | Food-contact safety is a finished-product assessment involving composition, surface condition, manufacturing, use conditions, and foreseeable misuse. | There is no single FDA approval number that universally certifies every stainless steel bowl set. Product-specific evidence and applicable U.S. requirements should be identified. | Article 3 of Regulation (EC) No. 1935/2004 prohibits harmful transfer and unacceptable changes to food; Article 17 addresses traceability. | LFGB Sections 30 and 31 address health protection and the transfer of substances to food; the test scope should reflect actual use. | Reject documents that only state “food grade” without naming the product, materials, test conditions, and applicable regulations. |
| Migration and release testing | Use a competent laboratory to select test media, temperature, and contact time that represent the intended foods and use. Test stainless steel and non-metal components separately when appropriate. | Testing should support the specific U.S. compliance rationale and intended-use conditions; a generic migration report may not cover coatings or accessories. | Use a documented risk-based test plan addressing metal release, possible non-metal migration, and sensory effects where relevant. | Request testing appropriate to LFGB expectations, including sensory evaluation when required by the material and intended use. | The report should identify sample code, material, food simulant or test medium, temperature, duration, laboratory accreditation, and pass/fail criteria. |
| Heavy metals and restricted substances | Evaluate possible release of nickel, chromium, iron, and other relevant constituents based on grade, surface condition, food type, and contact conditions. | Use a product-specific assessment; “stainless steel” does not mean that release is impossible under every condition. | Consider substances that could transfer in quantities affecting health or food quality under Article 3. | Include relevant elemental release and sensory risks in the LFGB test program. | Ask for a laboratory report tied to the actual bowl set, not only a raw-material declaration. |
| Acidic and salty food suitability | 304 is generally suitable for ordinary food use when properly manufactured, but prolonged exposure to concentrated salt, acidic marinades, or aggressive cleaners can increase corrosion risk. 316 may provide a wider corrosion margin. | Intended-use conditions must be stated; compliance should not be interpreted as unlimited resistance to corrosion or chemical attack. | Assess foreseeable use, including food type, temperature, duration, and cleaning conditions. | Use conditions should be reflected in the LFGB evaluation and consumer instructions. | Provide care instructions: do not store concentrated salt or acidic food for extended periods; rinse promptly after use. |
| Dishwasher and heat claims | “Dishwasher safe” and temperature limits should be supported by repeated-cycle testing on the complete set, including lids, seals, coatings, and labels. | Do not treat a dishwasher claim as an FDA compliance claim. Validate the actual cleaning process and component durability. | Document foreseeable cleaning conditions under the GMP and product risk assessment. | Check that repeated washing does not create unacceptable migration, odor, discoloration, cracking, or flaking. | Request a cycle count, detergent type, water temperature, drying conditions, and post-test inspection results. |
| Traceability and declarations | Maintain records linking finished goods to material batches, suppliers, production dates, inspection results, and test samples. | Keep the applicable U.S. compliance statement and supporting technical records for each food-contact component. | Regulation (EC) No. 1935/2004 requires traceability through the relevant stages of manufacture and distribution. | Maintain supplier declarations, test reports, production records, and product identification for market surveillance. | Require a dated declaration with product code, material list, intended use, limitations, and document revision number. |
| Minimum document package for global purchasing | Material certificate; component list; food-contact declaration; migration or release test report; coating and accessory evidence; manufacturing and inspection records; care instructions. | Product-specific evidence required | Framework + GMP + risk-based evidence | LFGB-specific test scope recommended | Documents must match the supplied dimensions, grade, finish, color, accessories, packaging, and intended market. |
| Recommended purchasing decision | Choose a set with verified 304 or 316 stainless steel, smooth food-contact surfaces, corrosion-resistant construction, no unverified food-contact coating, and complete documentation. | Use a clear U.S. compliance rationale instead of an unsupported “FDA approved” marketing phrase. | Confirm compliance with Regulation (EC) No. 1935/2004 and manufacturing under Regulation (EC) No. 2023/2006, plus applicable national requirements. | Confirm that the actual set and accessories are covered by the LFGB assessment and supporting laboratory reports. | Preferred: traceable material + complete finished-product test file |
