A 40HQ of Flat-Pack Cabinets into the US: Cube, Duty Base and Assembly Labor

6 November 2026 · US market · Fame Industry Co., Ltd.

The unit that matters is the container, not the cabinet

A US buyer compares price per cabinet, but freight, drayage, terminal handling and warehousing are all charged on volume or on the container. Two factories can quote the same unit price and land at different costs per kitchen simply because one packs a 2.4 meter run into 0.71 m3 and the other needs 1.1 m3 for the same run.

The arithmetic is worth writing out, because it is the only part of the quote that a spreadsheet can settle. A 40 foot high cube holds about 76 m3 nominally, and after stowage loss, carton voids and door-end blocking the planning figure is nearer 68 m3. At 0.71 m3 a run that is about 88 runs; at 1.1 m3 it is about 62. The same freight invoice spread over 26 fewer kitchens is the difference between a program that clears its landed target and one that quietly does not.

• 40HQ nominal volume: about 76 m3 internal; plan on about 68 m3 usable
• Flat-pack 2.4 m run at 0.71 m3: about 88 runs per 40HQ
• The same run at 1.1 m3: about 62 runs per 40HQ, on the same freight invoice
• Assembled 2.4 m run at about 2.4 m3: roughly 28 runs per 40HQ
• Per-run landed freight = total freight and terminal cost divided by runs loaded

Reloading into a 53-foot trailer is where a cheap plan breaks

Most US importers do not deliver a container; they reload it. A 53 foot domestic trailer has about 16.15 m of floor and 2.6 m of width, and the standard 48 x 40 inch GMA pallet is 1,219 x 1,016 mm. Thirteen rows of two pallets occupy 15.85 m of that floor, which is why 26 pallets is the working number rather than a guess.

The container is narrower than the trailer, and this is the detail that catches a first-time importer. Two GMA pallets cannot be loaded 1,219 mm edge across a 2.35 m container, because that is 2.44 m; they load with the 1,016 mm edge across and the length running fore and aft. A carton designed at 1,180 mm therefore belongs to the floor-loaded part of the container, not to the pallet stack, and a packing list that treats the two the same will produce a carton count that does not fit either.

• 53 ft trailer floor: about 16.15 m; thirteen rows of 48 x 40 in pallets use about 15.85 m
• GMA pallet: 48 x 40 in, or 1,219 x 1,016 mm
• Container internal width about 2.35 m: two pallets go 1,016 mm across, not 1,219 mm
• Floor loading gains roughly 5 to 8 percent cube over palletising, and costs handling time at destination
• A 1,180 mm carton is a floor-loaded carton, not a pallet carton

US duty is charged on the FOB value, not the CIF value

The single most common modelling error on a US landed-cost sheet is treating the duty base the way an EU sheet does. US customs value is transaction value: the price actually paid or payable for the goods, generally the FOB price, with international freight and insurance excluded. In the EU the base is built on CIF, so freight is inside it. A buyer who copies a European landed-cost template into a US program overstates the duty base, and a supplier who quotes CIF without saying so makes the duty line look larger than it is.

Transaction value is not simply the invoice number, though. Assists — tooling, moulds, engineering, and anything supplied free or at reduced cost by the buyer to the seller — are added, and so are packing costs and the seller's commission. That is the one line worth checking on a program where the buyer paid for a drilling jig or a custom decor plate, because the jig is dutiable even though it is not in the container.

• US customs value: transaction value, generally the FOB price, freight and insurance excluded
• EU comparison: the base is built on CIF, so the same goods carry a larger base in Europe
• Added to transaction value: assists such as buyer-supplied tooling, moulds and engineering
• Also added: packing costs and selling commission; deducted: post-importation transport if separately identified
• Practical rule: model the duty base from the FOB line, then reconcile against the entry summary

Section 301 is a line you verify, not a percentage you assume

Additional duty on Chinese-origin furniture is carried in Chapter 99, subchapter III of the HTS, keyed to the HTS line of the goods, and it is amended by notice rather than by the calendar. The lists are revised, exclusions are granted with an end date and then expire, and the rate that applied to the container you shipped last quarter is not evidence of the rate that applies to the one you are booking now. Two quotes can look identical on FOB and differ by the Chapter 99 line.

The workable process is not to memorise a rate but to fix the line. Ask for the ten-digit HTS classification in writing with the quotation, check it against the current Chapter 99 subchapter III headings, and put the classification and the duty basis on the purchase order so a later reclassification is a documented change rather than a surprise at entry. Where an exclusion exists, its scope and its expiry date belong in the file with the entry, not in an email.

• Chapter 99, subchapter III of the HTS carries the Section 301 additional duty headings
• The additional duty is keyed to the goods' own HTS line, not to the invoice description
• Exclusions are time-limited and their scope is specific; record the expiry date with the entry
• Put the ten-digit classification and the duty basis on the purchase order
• Verify the Chapter 99 line at booking, not at the previous container

Assembly labor is the number the factory quote leaves out

Flat-pack wins on freight and loses on labor, and the quote only prices one side of that trade. Assembly time per unit is a specification, so ask for it in minutes rather than in adjectives, then multiply: a seven-unit 2.4 meter run at 25 minutes a unit is just under three hours of bench time, plus unpacking, sorting and carton disposal, which typically adds a third. At a shop rate you supply, that is the entire comparison.

Two things move that number more than the cabinet does. Numbered panels and a paper template per carton cut sorting time, which is usually the largest single component of the labor; a hardware bag per carton instead of one bag per container removes a trip to a parts bin for every unit. If a supplier cannot state assembly minutes per unit, the comparison against an assembled cabinet cannot be made on price alone, because the missing number is the one that decides it.

• Ask for assembly time in minutes per unit, per cabinet, not as a description
• Seven units at 25 minutes is just under three hours of bench time per run before sorting and disposal
• Sorting and carton disposal typically add about a third to the assembly time
• Numbered panels plus a template per carton reduce the sorting component most
• One hardware bag per carton avoids a parts-bin trip per unit

Terms and the cash cycle on a container

A container ties up money three times: a deposit at order, the balance before the bill of lading is released, and duty plus the entry charges at clearance, before a single cabinet is sold. On 30 and 70 percent terms the full FOB value is committed roughly six weeks before sellable stock exists, and ocean transit from Ningbo or Shanghai to a US West Coast port adds another three to five weeks depending on routing and on whether the box is booked direct or through a consolidation.

The levers are ordinary. Ask for a shipping schedule that does not land two containers in the same week. Ask the forwarder for a credit line against the bill of lading rather than paying cash against the telex release. Confirm whether the entry can be filed on a periodic monthly statement, which for an importer with a standing bond and a customs broker moves the duty cash date by up to a month. None of it changes the landed cost per run, but all of it changes how many containers a year the business can actually finance.

• Typical terms: 30 percent deposit, 70 percent against the bill of lading
• Cash committed roughly six weeks before sellable stock exists
• Transit from Ningbo or Shanghai to the US West Coast: roughly three to five weeks port to port
• Duty and entry charges land at release, before any revenue from the container
• Levers: staggered schedule, forwarder credit, periodic monthly statement for duty

Normalizing three factory quotes onto one page

Three quotes in three formats are not comparable, and the difference is rarely the price per meter. Build one table with the same rows for every supplier: total cubic meters per run, gross kilograms per run, carton count and largest carton, board class and emission class with the mill named, hinge and runner brand and cycle rating, edge banding thickness, MOQ per finish, lead time after deposit, and the port of loading.

Two rows decide most of the outcome. Cubic meters per run is the freight row, and it is the one a factory is least likely to volunteer; gross kilograms per run is the handling row, and it is where a honeycomb or a thinner back panel shows up. A quote that cannot fill both rows is not a cheaper quote, it is an incomplete one, and the missing rows are exactly where the margin goes in year two.

• Rows to fix: m3 per run, kg per run, cartons per run, largest carton dimensions
• Board and emission class, with the panel mill named on the TSCA certificate
• Hinge and runner brand with cycle rating, edge banding thickness in mm
• MOQ per finish, lead time after deposit, port of loading, and the HTS line offered
• A quote missing m3 or kg per run is incomplete, not cheaper
