Block frozen
Product frozen together into a solid block, usually to a fixed block weight.
What it means for a buyer
Blocks suit processors who thaw and re-cut. They do not suit anyone who needs to take out a few pieces at a time.
Catch certificate
An official document evidencing that a wild catch was taken legally, required under IUU rules for entry to the EU and several other markets.
What it means for a buyer
Ask for the catch certificate at order stage, not at arrival. Retrospective documentation is difficult and sometimes impossible.
Cluster — CLST
A crab section comprising several legs attached to a piece of the body shell.
What it means for a buyer
Cluster grade is a weight band, not a quality statement. Meat fill, shell condition and leg breakage tolerance are separate fields.
Count
The number of pieces in a kilogram or a stated pack weight, used to grade shellfish.
What it means for a buyer
A count only means something when the form is attached: 80/120 shell-on is not 80/120 peeled.
Double frozen
Frozen, thawed for processing, and frozen again. A legitimate and common product that must be declared.
What it means for a buyer
Double-frozen product typically shows higher drip and softer texture. It is not inferior for every use — but it is a different purchase.
FAO fishing area
The FAO major fishing area a wild catch comes from. Norwegian catches fall in FAO 27, the Northeast Atlantic.
What it means for a buyer
FAO area is a labelling requirement in many markets. Sub-area and catch date are more useful commercially.
Fillet — FLT
The side of the fish removed from the frame, with or without skin and with a stated bone status.
What it means for a buyer
"Fillet" alone leaves skin, pin bones, trim level and net-weight basis undefined. All four belong in the specification.
Frozen at sea — FAS
Frozen aboard the catching vessel, normally within hours of capture.
What it means for a buyer
FAS and shore-frozen product behave differently in thaw loss and appearance, and are priced differently. State which you are buying.
Glaze
A protective layer of ice applied to frozen product to limit dehydration and oxidation, expressed as a percentage of gross weight.
What it means for a buyer
Glaze is water. A price quoted against glazed gross weight and a price quoted net of glaze are not comparable. Agree the percentage in writing.
Head-on gutted — HOG
Gutted fish with the head left on. The standard presentation for fresh Norwegian salmon and trout export.
What it means for a buyer
HOG and H&G are not the same thing and the weight difference is substantial. Write the abbreviation out in full on the purchase order if there is any chance of confusion.
Headed and gutted — H&G / HG
Gutted fish with the head removed. The standard presentation for frozen whitefish.
What it means for a buyer
Ask whether the H&G is sea frozen or shore frozen, and single or double frozen. The three letters cover both, and they price differently.
Incoterms
The ICC's standard trade terms defining where risk and cost pass between seller and buyer. The current edition is Incoterms 2020.
What it means for a buyer
Always write the named place after the term — "CIP Paris CDG", not "CIP". A term without a place is incomplete.
Individually quick frozen — IQF
Each piece frozen separately so the pieces stay loose rather than forming a block.
What it means for a buyer
IQF product usually carries glaze. Ask for the glaze percentage and price against net-of-glaze weight.
Interleaved
Individual pieces separated by film or paper so they can be taken apart while still frozen.
What it means for a buyer
Interleaving costs more to pack but saves labour and waste at the point of use. Weigh the two against your own operation.
J-cut — J-cut
A J-shaped cut behind the head that removes the nape and part of the belly flap, used principally on Greenland halibut.
What it means for a buyer
A J-cut fish weighs less than the same fish presented H&G, so H&G and J-cut weight bands are not interchangeable. Name the presentation before the band.
Klippfisk
Whitefish that has been salted and then dried. Distinct from saltfish, which is wet salted only.
What it means for a buyer
Klippfisk, saltfish and ready-desalted product have three different weight bases. Say which one you are buying.
Loin — LOIN
The thick, even forward section of the fillet, cut to a uniform shape and free of the thin belly and tail.
What it means for a buyer
Loin yield per fillet is limited, which is why loins carry a premium. Specify the weight band and whether the loin is skinless and boneless.
Meat fill
How full of meat a crab's shell is, expressed as a percentage, varying with the moult cycle.
What it means for a buyer
Specify a minimum fill and the method of assessment. Two clusters of the same weight can yield very different amounts of meat.
Net of glaze
The weight of the product after the glaze has been removed — the actual amount of seafood being sold.
What it means for a buyer
Make net-of-glaze the contractual weight basis and state the method by which it will be verified on arrival.
Peeled — PND
Shellfish with the shell removed, sold as meat.
What it means for a buyer
A count band for peeled product is a different band from the same product shell-on. Always write the form next to the count.
Portion — PORT
A fixed-weight piece cut from a fillet or loin to an agreed target weight and tolerance.
What it means for a buyer
Specify the target weight, the tolerance, whether it is a centre cut or tail cut, skin and bone status, and whether the weight is before or after glazing.
Pre-rigor and post-rigor
Whether the fish was filleted before or after rigor mortis set in.
What it means for a buyer
Pre-rigor filleting gives a different shape and a different gaping risk than post-rigor filleting. If it matters to your process, put it in the contract.
Single frozen
Frozen once, from fresh raw material, and never thawed and refrozen.
What it means for a buyer
Several destination markets require freezing history to be declared. Ask for it in writing rather than assuming it.
Split — SPLT
Fish opened out flat along the backbone, the base presentation for salting, drying and klippfisk production.
What it means for a buyer
Split fish size bands refer to the cured weight. State whether the weight is wet-salted or dried — they are far apart.
Stockfish
Whitefish, principally cod, air dried on racks without salt, then hand graded into commercial classes.
What it means for a buyer
Buy on the class name, the length band and the drying season — not on adjectives.
Trim (A–E)
A ladder of salmon and trout fillet trims describing which bones, fins, flaps and membranes have been removed, from Trim A through to Trim E.
What it means for a buyer
The letter does not define skin, belly depth in millimetres, tail treatment, colour, fat, rigor state or freezing history. Specify those separately.
Whole round — WR
The fish exactly as caught — nothing removed. Head, guts, fins and tail all present.
What it means for a buyer
Whole round weight is the highest weight the fish will ever have. Every later presentation weighs less, so never carry a WR band across to another form.
