FDA vs LFGB for Food-Grade Silicone Molds

“FDA” and “LFGB” are often used as shorthand in silicone sourcing, but they do not mean the same thing and neither phrase should be treated as a generic factory certificate.

For a custom food-contact silicone mold, the practical question is:

What material or finished article was evaluated, under which rule or test method, for which use conditions, and does that evidence match the product you are buying?

That is more useful than asking whether a supplier is simply “FDA” or “LFGB.”

United States: 21 CFR 177.2600

In the United States, 21 CFR 177.2600 concerns rubber articles intended for repeated use.

For an applicable reusable silicone mold, a buyer may see this regulation referenced in material or finished-article documentation.

What to verify:

• the tested material/article identity;
• the applicant/manufacturer shown in the report;
• the test or extraction conditions;
• the result;
• whether the material/color/use you are buying is within scope.

A reference to 21 CFR 177.2600 is not the same thing as saying the factory is “FDA approved.”

European Union: Regulation (EC) No 1935/2004

Regulation (EC) No 1935/2004 provides the general EU framework for materials and articles intended to come into contact with food.

Among other requirements, food-contact materials/articles should not transfer constituents to food in quantities that could endanger health, cause an unacceptable change in food composition or deteriorate organoleptic characteristics under normal or foreseeable conditions of use.

For a silicone mold, the buyer still needs to identify the material/article-specific evidence relevant to the actual project.

A broad reference to the framework regulation is not a substitute for confirming the tested material or product.

Germany: LFGB and BfR Recommendation XV

German buyer conversations often use “LFGB” as a shorthand for food-contact testing or compliance.

For silicones, BfR Recommendation XV is an important technical/scientific reference.

Two points matter:

1. BfR Recommendation XV specifically addresses silicones.
2. BfR recommendations are not legally binding standards; BfR describes them as scientific guidance reflecting the state of science and technology.

Therefore, a supplier should not reduce the subject to a generic “LFGB certificate” badge.

Ask what the report actually tested and which recommendation/regulatory requirement it references.

Why One Report Does Not Automatically Cover Every Product

A report can be limited by:

• material grade;
• pigment/color;
• cure or formulation;
• tested specimen;
• food simulant/contact condition;
• temperature;
• contact duration;
• repeated-use condition;
• test date/method;
• market/customer requirement.

If you change the silicone formulation, pigment or use condition, do not assume the same document automatically answers the new question.

Raw-Material Report vs Finished-Article Evidence

A raw-material or compound report can be useful.

But some buyers, retailers or applications may require evidence relating to the finished article.

Ask:

• Is this report for the raw compound, a standard specimen, or the finished mold?
• Does the report cover the same color/formulation?
• Do we need finished-article testing for our customer or market?
• Does the stated use condition resemble our real process?

The correct answer is project-specific.

“Platinum-Cured” Is Not the Same as “Food-Contact Compliant”

Platinum addition-cure silicone is commonly considered for food-contact mold applications, but cure chemistry alone does not prove compliance.

You still need to verify:

• the exact silicone grade;
• additives/pigments where relevant;
• processing/cure conditions;
• report scope;
• intended food-contact use.

Do not select a material only because the quotation says “platinum silicone.”

Use Conditions Matter

When asking for food-contact evidence, tell the supplier:

• what food/formula contacts the mold;
• maximum and normal contact temperature;
• contact duration;
• repeated use;
• cleaning/sanitation method;
• color/pigment requirement;
• destination market.

For example, a mold used for room-temperature chocolate and a tray receiving a hot confectionery mass do not have identical use conditions.

The documentation review should start from the real use.

A Buyer Checklist for Reviewing a Report

Before accepting a report as project evidence, check:

1. report number;
2. laboratory;
3. report date;
4. applicant;
5. sample/material name;
6. test method/regulatory reference;
7. test conditions;
8. result/conclusion;
9. limitations/notes;
10. whether it matches your selected material/color/use.

If the connection between the report and the product is unclear, ask the supplier to explain it in writing.

What to Put in the RFQ

Instead of writing only:

> “Need FDA/LFGB silicone.”

Write:

> “This is a reusable silicone mold for [food]. It will contact the product at approximately [condition] for [duration], will be cleaned by [method], and will be sold/used in [market]. Please identify the proposed silicone grade and the food-contact documentation available for that material/article. Our customer also requires [specific report/declaration, if known].”

That gives the supplier a real specification to review.

Frequently Asked Questions

Is there an “FDA-approved silicone mold factory” certificate?

That is not an accurate way to describe food-contact evidence. Ask for the applicable material/article documentation.

Is LFGB the same as an EU-wide silicone certificate?

No. EU food-contact compliance sits within the applicable EU legal framework, while German requirements/guidance and test practices need to be understood in their proper scope.

Is BfR Recommendation XV law?

BfR states that its food-contact recommendations are not legally binding standards. They are scientific/technical guidance used in practice.

Does a platinum-cure report cover every pigment color?

Not automatically. Verify whether the tested material/formulation and the production color fall within the report scope.

Do we always need finished-article testing?

Not necessarily. The required evidence depends on the project, destination market and customer/retailer requirements.
