Origin co-pack vs destination 3PL flat-pack (KD) landed cost and 40HQ estimator
Compare two ways to land a display program: displays assembled and packed at an origin co-packer and shipped built, or displays shipped flat (knocked down, KD) and assembled at a destination 3PL. Enter your own carton sizes, container rate and costs; the tool counts cartons per 40HQ container and works out freight and landed cost per display.
- Why flat shipping matters: one display maker calls knocked-down flat (KDF) the most efficient and least costly way to ship, because flat components stack far more densely on a pallet and in a trailer than an assembled structure; the tradeoff is assembly.[2][3]
- A display tray that ships flat and converts in-store reduces shipped volume compared with pre-assembled fixtures, while inefficient nest or non-flat pack designs increase cubic volume and freight spend.[4][5]
- The container defaults below are the published inside dimensions of a high cube (40HQ) container: 12.03 m long, 2.35 m wide and 2.69 m high. Replace them with your carrier's figures, and lower the usable fill to allow for door clearance, dunnage and loading gaps.[1]
- Not included: a widely repeated units-per-container comparison for flat versus rigid displays could not be checked (the publisher refused the request), so the tool has no default units per container. Every count comes from your carton sizes.
Estimates from published formulas and third-party figures; confirm on an unprinted white sample.
Shangle Display fixed offers: US$300 fixed price for a custom printed sample; US$200 fixed price for structure and artwork proof from your brief. Otherwise order quantity and production schedule confirmed per project brief and verified on an unprinted white sample; neutral unbranded export master cartons and tape, and blind shipping.
Cartons are counted as a simple grid in the best orientation allowed; real stowage plans and pallet patterns can load fewer. Weights only limit the count when both the payload limit and the carton weight are entered.
