Combination Plier: 1,127 cartons in a 40ft
90 pcs per carton, 0.0454 m3, 23.05 kg gross. A 20GP takes 616 cartons (55,440 pcs). A 40GP or 40HQ takes 1,127 cartons - 101,430 pcs - and stops on weight, not space.
CONTAINER PLANNING
Six KK models with published carton data, run through standard stowage maths. There is no single answer - there is a carton count, a piece count, and whichever limit you hit first.
Every figure on this page is calculated from carton data the factory already publishes per model: pieces per carton, carton volume in m3 and carton gross weight in kg. The container capacities used are practical capacities after stowage loss - 28 m3 and 21,700 kg for a 20GP, 56 m3 and 26,000 kg for a 40GP, 65 m3 and 26,000 kg for a 40HQ. Your forwarder's own allocation takes precedence; the method is what you can reuse.

SIX MODELS, REAL CARTON DATA
Each figure below comes from that model's own published packing line - pieces per carton, m3 and gross weight. No estimates.
90 pcs per carton, 0.0454 m3, 23.05 kg gross. A 20GP takes 616 cartons (55,440 pcs). A 40GP or 40HQ takes 1,127 cartons - 101,430 pcs - and stops on weight, not space.
120 pcs per carton, 0.0346 m3, 29.50 kg gross. A 20GP takes 735 cartons (88,200 pcs). A 40GP or 40HQ takes 881 cartons, held back by the heaviest carton weight in this group.
60 pcs per carton, 0.0400 m3, 25.10 kg gross. A 20GP takes 700 cartons (42,000 pcs). A 40GP or 40HQ takes 1,035 cartons - the volume allows 1,400, the payload allows 1,035.
48 pcs per carton, 0.0275 m3, 21.00 kg gross. A 20GP takes 1,018 cartons (48,864 pcs). A 40GP or 40HQ takes 1,238 cartons - 59,424 pcs - the largest carton count here.
72 pcs per carton, 0.0503 m3, 14.65 kg gross. A 20GP takes 556 cartons (40,032 pcs). A 40GP takes 1,113 cartons (80,136 pcs) but a 40HQ takes 1,292 (93,024 pcs) - volume-limited throughout.
40 pcs per carton, 0.0555 m3, 26.00 kg gross. A 20GP takes 504 cartons (20,160 pcs). A 40GP or 40HQ takes 1,000 cartons - 40,000 pcs. The carton volume allows more; the weight does not.

THE METHOD
A container fills until either the space or the payload runs out. The smaller number is the one you can promise.
Every model publishes three numbers: pieces per carton, carton volume in m3 and carton gross weight in kg. Those three decide the container, not the tool's own size.
A 20GP at 28 m3 of usable space takes 616 cartons of KK-101 at 0.0454 m3. The same sum on a 40GP at 56 m3 gives 1,233 cartons, and 1,431 on a 40HQ at 65 m3.
The same 20GP at 21,700 kg of payload takes 941 cartons of KK-101 at 23.05 kg. On a 40GP at 26,000 kg it takes 1,127 cartons.
A 20GP on KK-101 is volume-limited at 616 cartons. A 40GP is weight-limited at 1,127 - the volume would have allowed 1,233. The smaller figure is the answer you can hold.
616 cartons x 90 pcs gives 55,440 pcs in a 20GP; 1,127 x 90 gives 101,430 pcs in a 40GP or 40HQ. That is the number to test against your order quantity.
The capacities used here - 28 / 56 / 65 m3 and 21,700 / 26,000 / 26,000 kg - are practical figures after stowage loss, not nominal container ratings. Your forwarder's own allocation takes precedence.
WHAT THE NUMBERS MEAN
Four readings of the same table that change what you order and how you ship it.
On five of these six models the 40GP and the 40HQ load the same number of cartons, because the payload limit is reached before the volume limit. Only the lightest carton - the KK-400 at 14.65 kg - turns extra height into extra goods.
Loading several families together means adding up carton volume and carton weight across models, then finding the mix where neither limit is wasted. A heavy carton such as the tape at 29.50 kg fills payload before space; a light one such as the riveter fills space before payload. Blending the two loads more total goods than either alone.
The KK-628 screwdriver, KK-661 soldering iron, KK-504 hex key set and KK-638 tester set do not publish carton figures yet, so they are not modelled here. Rather than estimate them, ask - the figures are confirmed per model with the quotation.
Container maths decides whether your order quantity is one shipment or two, and whether a 40HQ is worth its premium. Running the carton numbers before the RFQ is what separates a quotation you can act on from a unit price you have to re-check.
