Seafood is FDA's highest-scrutiny food category — and the one category where the standard FSVP playbook doesn't actually apply. This guide walks foreign processors and US importers through registration, Seafood HACCP importer verification, prior notice, and labeling for the 2026 import season.
Most FDA-regulated foods route through the standard Foreign Supplier Verification Program. Seafood is one of only two food categories (juice is the other) with its own dedicated HACCP regulation that replaces FSVP outright. Get this distinction wrong and you'll build compliance paperwork for a program that doesn't apply to you — while missing the one that does.
Fish and fishery products processed in compliance with the Seafood HACCP regulation (21 CFR Part 123) are exempt from standard FSVP. Instead, importers must satisfy the importer-verification requirement at 21 CFR 123.12 — either by sourcing from a country with an active FDA equivalency agreement, or by taking documented "affirmative steps": obtaining the foreign processor's HACCP and sanitation records, a compliance certificate, on-site inspection, or periodic product testing. It looks like FSVP, functions like FSVP, but it is a separate rule with separate paperwork — see our seafood HACCP importer-verification guide for the full breakdown.
The same five checkpoints apply to every product we cover — the substance of each step changes for seafood.
Every foreign processor, repacker, and cold-storage facility handling seafood destined for the US needs FDA Food Facility Registration and a US Agent, renewed on the biennial window.
FDA requirements →Not FSVP — a written Seafood HACCP importer-verification program under 21 CFR 123.12, tied to species-specific hazards like histamine and parasites.
Verification guide →Filed before every shipment arrives — 8 hours by water, 4 by air or rail, 2 by road — with product, processor, and origin details matched exactly to the entry.
Prior notice guide →Correct market name from the Seafood List, allergen declaration (fish and shellfish are major allergens), and accurate fresh/frozen/processed claims.
Label requirements →Facility registration renews on FDA's shared biennial calendar — same window as every other food category we cover.
Renewal hub →Verified against FDA's Fish and Fishery Products Hazards and Controls Guidance and current import alert data — not generic "food safety" boilerplate.
Tuna, mahi-mahi, and other scombrotoxin-forming species can develop histamine after death if time-and-temperature control lapses. FDA's updated thresholds: 35 ppm or more is treated as evidence of decomposition; 200 ppm or more as an injurious deleterious substance. Once formed, histamine survives cooking and freezing.
Controlled via CGMP + HACCP cold chainSpecies intended for raw or undercooked consumption (sushi-grade fin fish in particular) require documented freezing treatments to kill parasites, per FDA's Fish and Fishery Products Hazards and Controls Guidance, Chapter 5.
Freezing log is part of the HACCP recordBeyond histamine-forming species, general decomposition from poor handling is independently actionable under FDA's companion compliance policy guide for non-scombrotoxin fish and fishery products.
Sensory + lab evidence both usedThe core label elements (market name, net weight, ingredient list, allergen statement, distributor info) apply to every form — but a few requirements shift depending on how the product is presented at retail.
| Requirement | Fresh (whole / fillet) | Frozen | Processed / value-added |
|---|---|---|---|
| Market name | Must match FDA's Seafood List acceptable market name — no invented or aspirational species names | Same Seafood List name required | Name must reflect what's actually in the package (e.g. "imitation crab" if surimi-based) |
| "Previously frozen" disclosure | Required if thawed before sale | Not applicable — sold frozen | Required if a frozen component was thawed during processing |
| Allergen statement | Required — fish and shellfish are both major food allergens | Required | Required, plus any allergens introduced by added ingredients (soy, egg, wheat in coatings) |
| Net weight basis | As-packed weight, drained if packed in liquid | Frozen weight, glaze excluded from declared net weight | Finished product weight including coating/sauce |
| Country of origin | Required at retail under separate COOL rules | Required | Required for the last substantial transformation country |
| Nutrition Facts | Required unless a specific small-business or raw single-ingredient exemption applies | Required | Required, reflecting the finished, as-sold product |
Seafood follows the same Prior Notice timing as every other imported food under 21 CFR Part 1, Subpart I — the seafood-specific risk is in what has to match, not when it's filed.
Timing: at least 8 hours before arrival by water, 4 hours by air or rail, 2 hours by road — measured from FDA's confirmation of the submission, not the moment you file.
What gets shipments detained: processing facility name mismatched to the registration on file, incorrect or missing FDA product code, and omitted allergen information. Because fish and shellfish are major allergens, an incomplete allergen field on the Prior Notice is treated the same as a mislabeled product.
Filing mechanics, the PN Confirmation Number, and what to do when shipment details change after confirmation.

Read the guide →Timing, required fields, and the most common causes of port detention.
Read the guide →Market names, allergen declarations, and fresh/frozen/processed differences.
Read the guide →What the US-side importer of record is legally responsible for, end to end.
Read the guide →No. Seafood processed in compliance with 21 CFR Part 123 is exempt from standard FSVP. Importers instead follow the importer-verification requirement in 21 CFR 123.12.
FDA's current compliance policy treats 35 ppm or more as evidence of decomposition, and 200 ppm or more as a deleterious substance that can render the fish injurious to health.
The same Prior Notice windows as other imported foods: at least 8 hours before arrival by water, 4 hours by air or rail, and 2 hours by road, from the time FDA confirms the submission.
