What Prior Notice is
Prior Notice is advance notification to FDA of an incoming food shipment, required under 21 CFR Part 1, Subpart I. It lets FDA target inspections at ports of entry and flag any credible risk before the shipment physically arrives. It applies to seafood the same way it applies to every other FDA-regulated food — there's no seafood-specific exemption from the filing requirement itself.
Timing requirements
| Mode of arrival | Minimum notice before arrival |
|---|---|
| By water | 8 hours |
| By air or rail | 4 hours |
| By road | 2 hours |
The clock starts when FDA confirms your submission for review — not when you hit submit. Build in buffer time, particularly around holidays or high-volume shipping windows when confirmation can take longer.
What has to match
The Prior Notice submission has to line up exactly with three other things: the processing facility's current FDA registration, the product code declared on the customs entry, and the label on the actual product. Where seafood differs from lower-risk categories is how strictly FDA checks that alignment — and how quickly a mismatch escalates to a hold.
- Processing facility name — must match the facility's active registration, not a former or informal name
- FDA product code — must correctly identify species and product form (fresh, frozen, canned, smoked, etc.)
- Allergen information — fish and shellfish are both major food allergens; an incomplete allergen field is treated the same as a mislabeled product
- Country of origin — including any country the shipment was previously refused entry from, if applicable
Where six-figure detention costs actually come from
The costliest Prior Notice errors for seafood importers aren't missing filings — they're filings that go in on time but list the wrong processing facility or omit allergen information. Once a shipment is held at port, storage fees and spoilage risk accumulate daily on a highly perishable product, which is why seafood importers should treat Prior Notice accuracy as a cost-control issue, not just a compliance checkbox.
Frequently asked
When does the Prior Notice clock start for seafood shipments?
When FDA confirms the submission for review — not the moment you submit it. Build in buffer time accordingly.
What's the most common reason seafood Prior Notice filings get held?
A mismatch between the listed processing facility and its current registration, an incorrect product code, or an incomplete allergen declaration.
