Vietnam's seafood exports closed 2025 at roughly $11.3 billion, up about 13% from the year before, and shrimp — the category that carries most of the breaded and marinated value-added lines — grew faster still, up around 19% to $4.6 billion, according to VASEP's year-end reporting. That gap matters: it reflects buyers shifting order mix toward coated, marinated, and ready-to-cook formats rather than raw block or headless shell-on, because those formats hold margin better on the retail and foodservice side. But "breaded shrimp" or "marinated fish" is not a single, comparable product across factories — it's a set of formulation choices that change your landed cost and your customer's plate yield, and most of those choices never appear on a quote unless you ask for them by name.
Coating pickup is the number that actually sets your price
The single biggest variable in a breaded product's economics is coating pickup — the weight of batter and breadcrumb as a percentage of total finished product weight. A shrimp piece coated at 30% pickup and one coated at 50% pickup can carry the same size count and look identical in a photo, but the second has roughly a third less actual shrimp meat per kilogram shipped. Factories quote per kilogram of finished, coated product by default, so a lower per-kilogram price with a higher pickup ratio is not necessarily the cheaper deal once you convert back to cost per kilogram of edible shrimp. Ask the factory to state pickup percentage as a contractual spec, not a marketing description like "lightly breaded" — and ask whether that figure is measured raw or after frying, since frying loses moisture and shifts the ratio again.
Glaze weight does the same thing to frozen fish
For IQF fillets and unbreaded marinated portions, the equivalent variable is glaze — the thin ice layer applied during freezing to protect the product from dehydration. A small glaze (2–4%) is standard practice; glaze in the 8–10%+ range starts to function as free water sold at the price of fish. Net weight versus gross weight should be stated explicitly on the packing list, and it's worth asking the factory directly what glaze percentage they run on the specific product you're ordering, since it's usually different for a plain fillet than for a marinated one where sauce also adds weight.
"Marinated" can mean three different things at three different factories
Marinade formulation is the least standardized part of this category. Some factories marinate to add flavor only, at a light coating; others marinate to add weight, with the sauce or brine designed to be partially absorbed into the muscle tissue before freezing, which changes both the declared weight and the product's behavior when a buyer's kitchen reheats it. If your recipe or retail label depends on a specific flavor profile or sodium content, request the actual marinade ingredient list and the target pickup percentage in writing — a verbal description like "garlic butter style" tells you nothing about whether the factory is adding 5% or 20% marinade weight.
What this means for your spec sheet
Before confirming a PO on any breaded, battered, or marinated line, get four numbers in writing rather than descriptive language: coating or marinade pickup percentage (and whether it's measured raw or post-cook), glaze percentage for any frozen component, net weight per case separate from gross weight, and the ingredient list for any applied coating or marinade if it affects labeling in your destination market. A factory that can produce those four numbers immediately, without needing to check with the production line, is generally one that runs formulation as a controlled process rather than adjusting it batch to batch — which is the detail that actually predicts whether your next container matches the sample that won you the order.
