Low-Acid and Acidified Canned Foods: FDA FCE and SID Registration Requirements

Low-acid canned foods (LACF) and acidified foods (AF) face a separate layer of FDA requirements on top of standard food facility registration. Producers of canned coconut milk, curry paste, canned soups, canned vegetables, hot sauces, pickled vegetables, and similar products must complete Food Canning Establishment (FCE) registration and file Scheduled Process Identifiers (SID) for each product before any shipment enters the United States. These obligations come from 21 CFR Part 113 (LACF) and 21 CFR Part 114 (AF) — regulations specifically designed to control Clostridium botulinum, a heat-resistant spore-forming bacterium that thrives in the anaerobic, low-acid environment inside a sealed can.

What qualifies as a low-acid or acidified canned food

Low-acid canned foods are thermally processed in hermetically sealed containers where the equilibrium pH is above 4.6 and the water activity is above 0.85. Common LACF products include canned vegetables, canned meat and fish products, canned soups and stews, canned legumes, and canned dairy products. Acidified foods start with a water activity above 0.85 but are brought to a final equilibrium pH of 4.6 or below through the addition of an acidifying agent — vinegar, citric acid, or another food-grade acidulant. Products in this category include salsa, hot sauce, pickled vegetables, relishes, and canned beans in acidified brine. The distinction matters because the applicable regulations differ, and the scheduled process for each product type must reflect which category it falls under.

The FCE registration: what it is and what it covers

The Food Canning Establishment number is the facility-level registration that authorizes a plant to manufacture LACF or AF products for the US market. FCE registration is filed through the FDA's LACF Online Registration System and is separate from the general food facility registration required under the Bioterrorism Act. The FCE number identifies the physical production site — a single company with multiple manufacturing locations must obtain an FCE number for each site. FCE registration has no expiration date but must be updated whenever the facility's legal name, address, or ownership changes. A facility that holds a standard food facility registration but lacks an FCE number cannot legally ship LACF or AF products to the United States, regardless of how long the facility has been registered in the general system.

The SID filing: scheduled processes for each product

Each individual LACF or AF product must have a separate Scheduled Process Identifier on file with the FDA before it can be shipped to the US. The SID filing describes the scheduled process — the scientifically validated combination of time, temperature, pH, water activity, and other critical factors that the facility will use to destroy Clostridium botulinum spores in that specific product. The scheduled process must be developed and validated by a process authority: a qualified food scientist or engineer with documented expertise in thermal processing and the applicable FDA regulations. The FDA does not itself validate or approve the scheduled process, but inspectors review the SID record and may request access to the underlying validation data. A missing, incomplete, or scientifically unsupported SID is a direct ground for shipment refusal.

Process authority: the bottleneck most exporters discover late

A process authority is a person or organization — typically a food science laboratory, university extension program, or specialized consulting firm — with documented expertise in thermal processing and familiarity with 21 CFR Parts 113 and 114. The process authority establishes or reviews the scheduled process, conducts or oversees the required validation studies (inoculated pack studies or thermal process calculations), and issues a process authority letter that supports the SID filing. Finding a qualified process authority, commissioning the validation studies, and completing the SID filing can take several months for a new product. Most foreign manufacturers discover this requirement only after a US importer or buyer asks for the SID number — at which point the validation work has not yet begun and the commercial timeline has already slipped.

How FDABridge handles FCE and SID registration

FDABridge manages both the general food facility registration and the FCE/SID filing process for foreign LACF and AF producers. We handle the FCE registration submission, coordinate with process authority resources to develop or validate the scheduled process, and file the SID records for each product.
