Garments on Hanger vs Flat-Pack: How to Ship Knitwear

By YZR Sweaters · 2026-11

Buyers usually meet this decision for the first time when a forwarder asks a deceptively simple question on the booking form: "flat or hanging?" We see this a lot with first-time importers of bulk sweater programmes — the instinct is that hanging garments upright must be "safer", the way a tailor ships a suit. For knitwear the honest answer is more interesting, because knits are neither as crease-prone as wovens nor as forgiving as t-shirts. Here is how we walk buyers through it.

What each method actually looks like

Flat-pack is the default of the knitwear trade. Garments are folded to a specified fold size, packed individually into polybags (with or without a hanger card inside to keep the fold crisp), packed into master cartons, and the cartons are palletised or floor-loaded into the container. A 40-foot high-cube can carry a startling number of sweaters this way — several thousand pieces of mid-weight knitwear is normal, because folded knitwear compresses politely.

GOH ("garments on hanger") turns the container into a rolling wardrobe: hanging rails or beam systems are installed across the container, garments travel on hangers in single or multi-tier configurations, and the floor space underneath can still carry boxed goods. The container arrives effectively as a mobile rail of sellable garments. The trade-off is immediate: hanging space is expensive space.

• Capacity. Hanging a garment typically consumes several times the volume of folding and bagging it. In plain terms, a GOH-loaded 40HQ often carries on the order of a third to half the pieces of the same container flat-packed. Your freight cost per piece roughly doubles or triples.
• Equipment. GOH racks or rails are fitted at the loading site; some forwarders own modular systems, some rent them per booking. That rental and handling cost is real and gets quoted into the freight.
• Hangers themselves. Specify them. A wide-shoulder plastic or recycled-board hanger supports the garment; a thin wire hanger punches dimples into knitwear shoulders over a five-week voyage — the exact damage you paid GOH to avoid.

When does GOH genuinely pay for knitwear?

The freight premium is only worth paying when it buys something concrete. The cases where we recommend hanging, or a hybrid, tend to be:

• Fine-gauge and delicate knits. Very fine merino or silk-blend knits show fold lines stubbornly, and the pressing line at destination is either unavailable or risky on the fabric.
• Embellished garments. Beading, sequins and heavy embroidery crush in flat packing. Hanging keeps the decoration geometry intact.
• Retail-ready floorset programmes. If garments go from container to store rail within days — a model many European chains run — GOH can eliminate the entire receive-press-repack step. The savings are counted in DC labour hours, not freight dollars.
• Structured or bulky shapes that do not fold. Some sculptural knits simply have no honest fold; forcing one creates permanent set lines.

And the cases where flat-pack is simply correct: everything else. Heavy cables and aran knits barely remember being folded. Cotton basics headed to an e-commerce fulfilment centre need to arrive boxed and pickable, not hanging. Any programme where landed cost per piece is the deciding metric will almost always choose flat, because freight is a bigger lever than DC labour for most importers.

The crease question for knits specifically

Knitwear forgives folding better than woven tailoring for one structural reason: the loops recover. Given a little time, warmth and gravity, most fold creases in a healthy knit relax out. The risk factors are fibre and finish, not folding itself:

• Acrylic and flat polybag packing plus heat is the classic bad combination — a container crossing the equator can set creases semi-permanently into heat-sensitive fibre. Ventilated packing and avoiding over-compression matter more than hangers here.
• Tightly twisted, high-density merino holds creases longer than loftier woollen-spun yarns.
• Long folds through printed or intarsia panels can crack the pattern line visually; fold placement specified in the packing note keeps the fold off the artwork.

For flat-packed shipments the standard remedy at destination is a steam tunnel or a day on a rail in a warm room — cheap, fast, and non-damaging when done properly, unlike pressing an embellished garment ever is. If your DC has no steaming capability at all, tilt the decision toward GOH for your delicate styles.

Specifying the packing method so nothing is left to chance

• Write the method into the PO and the packing spec. "Flat pack, 12 pieces per polybag inner, 6 inners per master carton, fold A as per approved sample" or "GOH, wide-shoulder hangers, single-tier, two garments per hanger". Ambiguity here is where packing complaints are born.
• Agree hanger ownership. Hangers can be buyer-supplied, factory-supplied, or on a returnable loop run by the forwarder. Each has a cost line somewhere; make sure it is in someone's quote deliberately.
• Do the maths on the whole chain. Compare freight-per-piece under both loadings against the DC touch cost saved, the markdown avoided on garments that reach the floor faster, and the value of consistency across a programme's reorders. One season of honest numbers beats any rule of thumb.
• Consider hybrid loading. GOH section for the hero styles, flat floor section under the rails for basics — common with chains running mixed programmes in one staggered shipment plan.
• Check the receiving end. A container of hanging garments needs a dock team ready to receive rails quickly; garment rails idling on a hot dock undo the advantage. Book the unload window like any delivery.

At YZR Sweaters we are a Dongguan knitwear factory shipping for fashion brands, wholesalers and online retailers, and we pack to a written specification on every order — fold diagrams, polybag and carton counts, desiccant and pallet standards included. If you are deciding between hanging and flat for your programme, send us the styles and the destination handling setup, and we will quote the packing that fits both.
