How to write a frozen seafood specification that survives the quotation

Most re-quotes come from four ambiguous lines: size grade, processing form, glaze and packing. Here is how to close each one so the price you are quoted is the price you pay.

A quotation that has to be revised is usually not a pricing problem. It is a specification that left two questions open. These are the four that cause most of the back-and-forth on frozen seafood orders.

1. Size grade: give a band, and give the tolerance

"Medium mackerel" means something different in Lagos, Bangkok and Tokyo. A grade is a weight band, for example 200–300 g per fish, and it needs a stated tolerance: what happens to a fish at 190 g or 310 g. Buyers who write the band and the tolerance get one price. Buyers who write "medium" get a range, and then a negotiation at the port.

2. Processing form: name the cut precisely

Whole round, gutted, HGT (headed, gutted, tailed), fillet, tube, ring, wing, neck, tentacle. Each of these changes the yield from landed weight, and yield is what the price is built on. HGT is the one that most often surprises buyers: you are paying for labour and losing weight, so the per-kilo price rises while the per-fish cost may not. If your cost model is per kilo of finished product, quote the finished form. If it is per fish, quote landed weight and ask for the yield figure.

3. Glaze: state the percentage, and say how it is measured

Glaze protects the product from freezer burn, and it is water. A 10% glaze on a 10 kg carton is roughly 1 kg of ice. That is legitimate protection, but it has to be declared, and the buyer needs to know whether the declared net weight is before or after glaze. Write the percentage and the basis. It is the single most common cause of a claim on arrival, and it is entirely avoidable on paper.

4. Packing: inner weight, carton weight, and the label

Bulk 10 kg or 20 kg cartons, or retail-ready inner packs. Say which, say the carton count per pallet if palletising matters to your warehouse, and send artwork with the label copy in the destination language. Label wording is a regulatory matter in most markets and is not something a supplier should be guessing at.

What a complete enquiry looks like

Species; size band and tolerance; processing form; freezing method (IQF or block); glaze percentage and basis; packing and label; quantity and destination port; and any certificate your authority requires. Send that and the reply is a firm quotation with a loading window.
