Detailed Explanation of the German LFGB Certification Report for Office Insulated Water Bottles
Office insulated water bottles, as typical double-walled food contact containers (the inner liner contacts drinking water/beverages, while the outer shell may come into contact with hands and desktops), fall under the core category regulated by LFGB. LFGB certification is a mandatory entry requirement for the German market; products that have not passed certification are prohibited from being sold in Germany.
I. Certification Standards and Regulatory Basis
| Item | Content | Key Requirements
| Regulatory Basis | LFGB §30/31 (Food, Consumer Goods and Feed Law) | Food contact materials must not endanger human health
| Testing Standards | BfR Recommendation (German Federal Institute for Risk Assessment) | Specific migration limits for various raw materials
| EU Framework | EU 10/2011 (Plastics for Food Contact) | General migration limit 60 mg/kg
| Special Requirements | Additional Clauses of German LFGB §31 | Stricter than the EU: Sensory testing is mandatory
II. Key Testing Items for Insulated Water Bottles
Insulated water bottles involve a combination of various materials and require separate testing for each:
1. Inner Liner (Stainless Steel, Vacuum Coating)
Lead (Pb), Cadmium (Cd), Chromium (Cr), Nickel (Ni) Migration
Stainless steel must be 304/316 food-grade (austenitic stainless steel)
Testing Conditions: 70°C × 2 hours, simulating hot beverage contact
2. Sealing rings/gaskets (silicone or rubber)
Volatile organic compounds (VOM) test
Formaldehyde and nitrosamine migration (essential for rubber)
Heavy metal (lead, cadmium, mercury, hexavalent chromium) leaching
3. Plastic/coated parts (e.g., cup lid, outer shell coating)
Heavy metals (lead, cadmium, mercury, hexavalent chromium)
Phytaldehyde esters (DBP, DEHP, BBP, DIBP)
Polycyclic aromatic hydrocarbons (PAHs) - common requirements for German GS certification
4. Printing/Logo inks
Heavy metal migration (lead, cadmium, barium, selenium, etc.)
Sensory testing (odor, transfer substances)
5. Welding/connection points
Heavy metal migration detection
Sealing test
III. Core differences between LFGB and ordinary EU food-grade testing
LFGB's unique sensory test is a crucial step often overlooked by companies:
Odor test: 60°C Soak in distilled water for 30 minutes and test for odor.
Odor Test: Compare soaking water with control water.
Appearance Test: Check for turbidity, sedimentation, and discoloration.
❌ Passing EU 10/2011 testing ≠ Passing LFGB certification.
✅ LFGB = EU testing + sensory testing + BfR specific requirements.
IV. Core Contents of the Test Report
A complete LFGB test report should include:
Report Number: LFGB-XXXX-XXXX
Applicant: XX Thermos Manufacturing Co., Ltd.
Product Name: Office Vacuum Insulated Water Bottle
Model/Specification: 500ml / 304 Stainless Steel
Testing Basis: LFGB §30/31, BfR Recommendation, EU 10/2011
Testing Items:
Heavy metal migration (lead, cadmium, nickel, chromium, etc.)
Sensory testing (odor, taste)
Specific migration (formaldehyde, nitrosamines, etc.)
Volatile organic compounds
Testing Conditions: Simulated operating temperature 70°C × 2 hours
Test Results: All tested items meet LFGB limits.
Testing Cycle: Typically 5-7 working days
Qualification Seals: CMA + CNAS (Dezewei Testing CNAS Registration No.: L8083)
V. Processing Procedure
| Steps | Content | Duration
| ① Initial Consultation | Provide product BOM, material specifications, and drawings
| ② Sample Preparation | Submit complete finished products for testing; 2-3 samples are recommended.
| ③ Laboratory Testing | Dezewei Testing CNAS Registration No.: L8083 | 5-7 days
| ④ Report Issuance | English/German report, including laboratory accreditation
| ⑤ Follow-up Services | Assistance with LFGB compliance declaration available. Long-term validity
VI. Key Considerations
Report Validity: Usually 1-2 years, but German customs and retailers tend to accept reports within 1 year.
Material Changes Require Retesting: If the stainless steel supplier, sealing ring material, or manufacturing process is changed, retesting is mandatory.
Packaging Labeling: The product packaging must declare "Für den Kontakt mit Lebensmitteln geeignet" (Suitable for food contact).
Common Risk Points for Exceeding Standards:
Inner liner stainless steel is not 304/316 food grade.
Sealing ring silicone contains excessive volatile substances.
Painted outer shell coating contains PAHs or heavy metals.
Welding points contain lead (rivets, solder).
Recommended to obtain simultaneously:
German LFGB (mandatory)
EU Declaration on Food Contact Materials
German GS Certification (enhances market competitiveness, required by retailers)
VII. Cost Reference
Routine Testing (Basic Items): Approximately RMB 800-2500
