FDA vs LFGB Food-Grade Silicone — What Buyers Need to Know

Silicone kitchenware certification documents — FDA 21 CFR 177.2600 and LFGB Section 30/31 — side-by-side on a lab bench Certification

If you sell silicone kitchenware to retail — drying mats, drying racks, sink grids, baby bottle nipples, baking molds — you have probably been asked: “do you have FDA or LFGB certification?” The honest answer for most factories is “both, for any production run that needs it.” But the framing matters, because FDA and LFGB are not redundant — they test different things, and procurement managers should be specific about which one their program actually needs.

FDA 21 CFR 177.2600 and LFGB §30/31 are not interchangeable. FDA confirms the silicone formulation uses approved ingredients; LFGB tests the finished part for organic volatile release after thermal aging. US retail programs require FDA; EU retail programs require LFGB; serious silicone OEMs run both per production batch, not once-per-formulation.

This is the short version we wish someone had given us when we started running OEM silicone programs.

What is FDA 21 CFR 177.2600?

FDA 21 CFR 177.2600 is the United States Food and Drug Administration’s regulation for “Rubber Articles Intended for Repeated Use” — which is the category silicone kitchenware falls into. It sets out which raw materials are permitted in the silicone compound, and caps the amount of extractives that can leach when soaked in water and n-hexane under specific test conditions.

What it actually tests for: approved raw material list, total extractables in water, total extractables in n-hexane.

What it does not test for: what migrates into hot food, what comes out when the product is heated to cooking temperatures, behavior under fatty foods, PFAS / forever chemicals.

Pass / fail standard. There is no “grade A” vs “grade B” — a sample either passes or it doesn’t.

What is LFGB Section 30/31?

LFGB stands for Lebensmittel-, Bedarfsgegenstände- und Futtermittelgesetzbuch — Germany’s Food, Consumer Goods, and Feed Code. Section 30 governs materials that come into contact with food, and Annex 8 (often referenced together as “LFGB §30/31”) sets the test methodology for silicone and rubber.

What it actually tests for: organic volatile compounds released during simulated cooking — heating the silicone in distilled water, in citric acid solution, and in n-heptane (a stand-in for fatty foods). The compound count, total weight, and specific identified compounds are reported.

What it does not directly test: raw material composition (it tests output, not input).

A pass on LFGB implies a pass on FDA. Because LFGB is testing what comes out of the silicone during use — which is what FDA is trying to indirectly control via its composition rules — material that passes LFGB will essentially always pass FDA. The reverse is not guaranteed.

When you need which

MarketMinimum requiredStrongly recommended
US retail (Amazon, Target, Walmart)FDA 21 CFR 177.2600LFGB if premium positioning
US premium retail (Whole Foods, Williams Sonoma, Sur La Table)FDALFGB + PFAS-free
CanadaFDA (often referenced)LFGB
EU (Germany, Netherlands, France, Nordics)LFGB §30/31+ REACH
UK (post-Brexit)LFGB still de facto standard+ REACH-UK
JapanJapan Food Sanitation Law (MHLW)LFGB often satisfies importers
Australia / NZFDA or LFGB acceptedLFGB preferred

If you sell to both US and EU retail, default to LFGB. The marginal per-batch cost is small (~$200-$500 difference) and you avoid running two separate certifications.

What to demand from your silicone supplier

The way to tell a serious silicone factory from a trading company-fronting-as-a-factory is to ask for the test report — not the verbal claim, not a 5-year-old certificate from a different SKU. Specifically:

  1. Third-party lab report from SGS, Intertek, TÜV Rheinland, or Bureau Veritas. In-house lab reports are not credible to your retail buyer.
  2. Issued within 18 months of the order. Older reports may not reflect the current batch.
  3. References the specific master-batch lot going into your production run. A generic “our material passes FDA” report is not enough — production batches use different master-batch lots, and contamination can occur in mixing.
  4. References the certification standard explicitly — “FDA 21 CFR 177.2600” or “LFGB §30/31 Annex 8” should appear in the report header.
  5. Per production run for premium retail (Whole Foods, Williams Sonoma). A single annual report does not satisfy their procurement audit.

If a supplier hesitates on any of these, that is a red flag.

A word on PFAS

PFAS — per- and polyfluoroalkyl substances, the “forever chemicals” — are not part of FDA or LFGB testing. They became a concern for silicone kitchenware because some peroxide-cured silicone formulations historically used PFAS-containing process aids during curing.

Platinum-cured silicone does not need PFAS-based process aids and is intrinsically PFAS-free. Peroxide-cured silicone can be PFAS-free if the supplier specifies PFAS-free process aids — but this is not the default for low-cost peroxide compounds.

If your retail buyer asks “are these PFAS-free?”, the safe answer is to spec platinum-cured silicone and ask your supplier for an independent non-detect test report. We do this routinely for premium kitchenware programs.

The bottom line

If you are sourcing silicone kitchenware for any program above commodity tier, the minimum spec is:

  • Material: food-grade silicone, ideally platinum-cured for premium SKUs
  • Certification: FDA 21 CFR 177.2600 for US-only; LFGB §30/31 for EU or US-EU dual; both for global programs
  • PFAS-free test report if your buyer is in the premium retail orbit
  • Per-batch third-party test report referencing your master-batch lot, issued within 18 months

Suppliers who routinely deliver this paperwork — without making it a separate negotiation — are the factories that have been doing this for years. The ones who haggle on the testing report are the ones to walk away from.

FAQ

  • Is LFGB stricter than FDA for food-grade silicone?

    Yes. FDA 21 CFR 177.2600 tests the silicone material composition for permitted ingredients. LFGB Section 30/31 goes further — it tests organic volatiles released during simulated cooking (heat, oils, acids), measuring what actually migrates into food. A material that passes LFGB always passes FDA; the reverse is not guaranteed.

  • How much does FDA / LFGB certification cost as a buyer?

    If your supplier is already running food-grade silicone, the per-batch certification reporting cost ($300-$1,500) is absorbed in pricing. If your supplier doesn't have it set up, they will quote a tooling + first-test fee ($2,000-$5,000) for the program. Avoid the latter — it usually means they were running non-food-grade material before.

  • What test report should I demand from my silicone supplier?

    Ask for a third-party (SGS, Intertek, or TÜV) test report referencing your specific master-batch lot number, your product geometry, and the certification standard (FDA 21 CFR 177.2600 OR LFGB Section 30/31 — typically Annex 8 for kitchenware). Reports older than 18 months are stale; demand fresh testing per production run for premium retail programs.

  • Does food-grade also mean PFAS-free?

    No — these are separate concerns. FDA and LFGB do not currently test for PFAS / forever chemicals in silicone. If your buyer (Whole Foods, Target Good & Gather, Patagonia Provisions) requires PFAS-free, you need a separate non-detect test report. Reputable platinum-cured silicone suppliers can provide it; peroxide-cured grades sometimes cannot.

  • What certifications do US and EU retailers actually require for silicone kitchen products?

    US retail baseline is FDA 21 CFR 177.2600 — required by Target, Walmart, Costco, Home Depot, and most Tier 2 chains. EU retail baseline is LFGB §30/31 (typically Annex 8 for kitchenware) — required by Carrefour, Tesco, Sainsbury's, and most EU chains. Premium retailers in both regions (Whole Foods, Williams Sonoma, Patagonia Provisions, EU premium chains) increasingly require PFAS-free non-detect documentation on top of FDA/LFGB. Sink-brand OEM programs typically require all three: FDA + LFGB + PFAS-free, issued per production batch by an accredited third-party lab.
