Start from real capacity, not brochure numbers. A 20ft GP offers about 28-30 usable CBM against 33 theoretical, a 40ft GP about 58-61, and a 40ft HQ about 65-69 of its 76.3 theoretical cubic metres, because cartons cannot sit flush against corrugated walls, the door header steals height, and irregular boxes create dead space. Furniture is almost always volume-limited rather than weight-limited; the two exceptions that hit the roughly 26-28 tonne payload wall first are solid carved wood loads and flat-shipped bonnell spring mattresses. Below about 13-15 CBM, LCL at typical rates of USD 80-200 per CBM usually beats booking a 20ft.
The quantities that matter, knocked down where the product allows it: a three-seat sofa packs around 1.6 CBM with detachable arms giving roughly 40 per 40HQ, a classic 3+3+1 living set 12-16 sets, a corner sofa group 16-21, a six-piece bedroom set about 2 CBM flat-packed for roughly 30 sets, a dining table with six chairs about 60 sets, a full dining room 30, a flat-pack kitchen at 0.30 CBM per linear metre for about 36 six-metre kitchens, TV units around 295, and mixed RTA panel furniture around 430 pieces at an average 0.15 CBM. Classic carved furniture ships crated and assembled at 6-8 CBM per room set, which means 8-10 sets per container and mandatory ISPM 15 heat-treated crating.
Two engineering decisions dominate the freight line. Knock-down construction cuts upholstered and casegoods volume by 25-47 percent, which is 30-50 percent more units in the same container and roughly a third off freight per set on a 3+3+1 program, for zero product change; most Inegol and Kayseri factories will do detachable arms and flat packing on request but do not offer it in the catalogue, so the buyer must ask. Roll-packing takes a queen mattress from 0.80 to 0.17 CBM, a 4.7 times density gain that drops per-unit freight from about USD 68 to about USD 14.50 on a USD 5,500 container; a mattress supplier without roll-pack capability is structurally uncompetitive for export.
The one-line rules buyers can plan with
A 40HQ is roughly 30 knock-down bedroom sets or 14 assembled; 12-16 living room sets; about 60 table-and-six-chairs sets; about 380 roll-packed foam queens or 230 pocket-spring; about 36 flat-pack kitchens; 8-10 classic carved room sets. One 40HQ also equals roughly one villa reception floor: a living set, a dining room and a bedroom with accessories at 23-25 CBM.
Mixed containers are the Turkish advantage
Turkish factories rarely enforce hard per-SKU minimums; they enforce a container minimum. The working question is how many SKUs fit in one 40HQ before a small-lot surcharge appears, and the answer is usually 8-15. High-value-per-CBM fillers such as TV units, bookcases, consoles and nesting tables are bought last, in the quantity that closes the container to full utilisation.
What a container is worth
Typical FOB values run USD 50,000-150,000 for mid-market mixed loads; an economy knock-down bedroom load prices around USD 20,000-45,000 while a classic carved 40HQ at 8 sets can pass USD 48,000 on mid-range pricing alone. These are planning bands, not quotations, and the per-product FOB ranges behind them are published on each category page.
