3-A Sanitary Certification
3-A Sanitary Standards are voluntary requirements for equipment and components used in food, dairy, beverage, and other hygienic processing environments.
They address material suitability, equipment design, surface condition, cleanability, and areas where residue or microorganisms may collect.
Food and dairy manufacturers use 3-A documentation to review equipment, seals, replacement components, and product-contact materials.
A 3-A authorization applies only to the products, compounds, manufacturing scope, and conditions identified in the official documentation. It should not be treated as approval for every silicone product made by a manufacturer.
3-A Sanitary Standards provide recognized criteria for materials and equipment used in hygienic food, dairy, and beverage processing.
Elastostar Rubber Corporation manufactures custom silicone gaskets, seals, tubing, O-rings, and extruded profiles for sanitary processing equipment.
Our 3-A documentation helps food processors, dairy manufacturers, equipment builders, and procurement teams verify certification status for covered silicone products.
Customers can also request supporting material and quality documentation for equipment design, supplier approval, and product qualification.

3-A Sanitary Standards vs FDA Food-Contact Requirements
3-A focuses on sanitary requirements for hygienic processing equipment.
FDA 21 CFR 177.2600 applies to rubber articles for applicable repeated-use food contact.
Each requirement should be verified separately for the specific material and application.
3-A Sanitary Certification FAQs
3-A sanitary certification confirms that specified products, materials, or equipment fall within an authorized scope based on recognized hygienic design and material requirements. It is commonly reviewed for dairy , food, and beverage-processing applications.
Coverage is limited to the silicone compounds, product forms, and manufacturing scope listed in Elastostar’s current 3-A certificate or authorization. Customers should review the certificate or request confirmation for a specific part before placing an order.
No, The certification applies only to the products and materials identified in the official authorization. Other silicone grades or custom components may meet different specifications without being covered by the 3-A certificate.
