Most kitchens that reject Japanese Wagyu reject it on a quoted price per kilo. That is the wrong denominator for a buffet or a banquet. A carving station does not sell kilos; it sells covers. Until the quoted price is converted into baht per cover at a realistic portion weight, the decision is being made on a number that has almost no relationship to the beef line in your food-cost report.
This article is for F&B directors, executive chefs and the purchasing managers in the same group who have never seriously priced Japanese Wagyu by cut, and who need to answer one question before anything else: could a small amount of Wagyu at a visible station pay for itself per cover? It is the step before import mechanics. If you have already decided to import and want to compare duty tiers against grade — which grade is cheapest to land in Thailand — that is covered in the Thai tariff tier vs. grade cost map. If you run large fixed banquet counts under Macau conditions and want yield worked per cut rather than per cover, see the Macau casino-hotel banquet yield article. If you are a distributor converting a quoted kilo into sellable pounds for resale rather than costing a service, see the quoted-kilo to sellable-pound ledger. Here, Thai landed cost is only an input. The topic is the per-cover model.
Why per kilo misleads a banquet kitchen
Three things break the per-kilo comparison between imported grain-fed beef and Japanese Wagyu.
The portion guests accept is not the same. A carving station slice of grain-fed striploin is a plate item; guests take a slice sized like a main course. A high-marbled Japanese cut carved thin at a visible station is treated as a tasting item. Chefs in our customer base plan Wagyu station portions in the 25–40 g range against 90–150 g for the grain-fed item they partially replace. These are planning bands from our own trading experience, not measured survey data — you should overwrite them with your own service counts after one trial.
Trim and cook loss differ by cut and by grade. The sellable weight after seam trim, fat cap removal and cooking is what you actually serve. A landed kilo is not a sellable kilo, and two cuts landed at the same price per kilo can differ substantially in sellable grams.
The station changes behavior at the rest of the line. A visible carving or teppan station with a named Japanese cut absorbs demand that would otherwise flow to the bulk beef item. Whether that offset is real in your operation is measurable in a single service; it is not something an article can assert for you.
The Wagyu per-cover worksheet
Work through the five steps below with your own numbers. Every band we give is a starting placeholder to be replaced.
Step 1 — Start from a quote by cut, not a single Wagyu price
"Wagyu" is not a price. Ask for USD/kg by cut, because the cuts that suit a station and the cuts that suit a plated set menu sit at very different levels. For a carving or teppan station, the cuts worth quoting are typically chuck roll, rump cap, striploin and short plate. Record each quote with its date and the volume it assumes; Japanese wholesale beef prices move with season and supply, and the Ministry of Agriculture, Forestry and Fisheries publishes market and policy material on Japanese beef exports at maff.go.jp.
Step 2 — Build the Thailand landed-cost stack
Add, in order, on top of the FOB or CIF quote:
- Import duty on the relevant HS line for chilled or frozen beef, plus VAT. Rates and any preferential eligibility (for example under JTEPA or RCEP) must be checked for your specific HS line with Thai Customs at the time you quote, and re-verified at least annually. Do not carry a rate forward from last year's file.
- Chilled air freight, Japan to Bangkok, per kg. Publish this in your worksheet as a range with an "as of" month, because lane rates move quarterly. Get the current band from your forwarder rather than from any article.
- Customs clearance and inspection handling, expressed in days as well as baht — the days matter in Step 4.
- Cold-store holding to the service date.
- Local importer margin, if you buy through one rather than direct. Whether your group buys direct or through a Thai importer changes this stack materially, so build both columns if you are unsure.
The output of Step 2 is landed THB per kilo, per cut. Nothing before this point is comparable to your current beef cost.
Step 3 — Convert landed kilos into sellable grams
Apply a trim yield and a cook loss to each cut, then multiply. Landed THB per kilo ÷ (trim yield × cook yield) ÷ 1,000 = landed THB per sellable gram. Measure both factors in your own kitchen on the first case you receive: weigh the primal in, weigh it after butchery, weigh a test batch before and after cooking at your station's actual holding temperature. Yields quoted by anyone who has not cooked in your kitchen are assumptions, including ours.
Step 4 — Divide by portion grams to get THB per cover
Multiply landed THB per sellable gram by the portion you will actually serve. Run it at three portion sizes so the shape of the decision is visible:
- 25 g — garnish or accent slice on an existing dish
- 40 g — carved slice at a visible station
- 90 g — plated set-menu portion
Now compare that figure against the beef cost per cover you are carrying today, computed the same way. This is the only comparison that means anything.
Step 5 — Three columns and a break-even
Lay the service out in three columns: current imported grain-fed beef only; Wagyu only; and a blended station where a Wagyu accent sits alongside a reduced quantity of the grain-fed item. For each column, record beef cost per cover, total beef cost for the service, and the portion assumption behind it.
The break-even question is: at what cover count does the blended station cost the same as today's line, once the reduced grain-fed volume is netted off? Above that count it is usually cheaper than chefs expect, because the substitution runs at a third of the gram weight.
Add one final line to the sheet: the minimum order that does not outlive your chilled shelf days. Take the shelf life remaining on arrival, subtract clearance days from Step 2, and subtract your safety margin. Whatever service volume you cannot consume inside that window either goes to frozen or should not be ordered chilled. An order quantity that beats the price per kilo but expires before service is not a saving.
The one-page version for the GM
Purchasing managers and GMs do not need the yield arithmetic. Hand them four lines: beef cost per cover today; beef cost per cover with the blended station; the cover count at which they are equal; and the order quantity and shelf-day window that assumption depends on. If the first two lines are within a few baht of each other, the discussion moves from cost to guest perception — which is a different, and much easier, conversation.
What you cannot fill in alone
Two inputs in this worksheet cannot be estimated honestly from the outside.
The actual USD/kg by cut at your volume. Published ranges and market reports — for example JETRO's market material at jetro.go.jp — describe the market, not your quote. A first hotel trial, a recurring monthly banquet program and a group-wide rollout are three different prices.
Whether the grade you assumed matches what a slice looks like on your carving board. Marbling grade is a specification, not an appearance guarantee at a specific thickness and portion weight. The visual effect at a station depends on cut, slice thickness and grade together.
Send us the cuts and the portion sizes you plugged into Step 4, and we will quote by cut so the per-cover column can be closed with real numbers instead of placeholder bands.
