Plan on three to five months from first email to a container on the water — and expect production to be the shortest part of it. On a first custom order most of the calendar disappears into supplier vetting and sample rounds, both of which happen before a single sellable unit is made.

How long does each stage really take?

Roughly 12 to 20 weeks, and production is usually only a third of it. A realistic first-order sequence runs: shortlisting and vetting suppliers, typically 2–4 weeks; quotation and terms, 1–2 weeks; sampling with revisions, 3–6 weeks; mass production, 4–8 weeks; then inspection, booking and ocean transit, another 4–8 weeks depending on the lane. Categories that need tooling or certification testing sit at the long end of every one of those bands.

Why does sampling take longer than the production run?

Most first orders lose more days to sample rounds than to the factory floor. A first sample rarely lands on spec. Two or three revision cycles are normal, and each carries courier time in both directions plus a wait for the factory’s sample room. The phase ends when a signed golden sample is locked into the order — so it is worth requesting the sample properly the first time, and knowing what happens after approval.

Can you skip sampling and go straight to production?

Only for stock items you have physically handled. If you are buying an existing catalogue product unchanged, a reference unit plus a signed spec sheet can be enough. For anything customised — your dimensions, your material, your logo, your packaging — skipping the sample moves the risk to the full order quantity rather than removing it. A failed sample costs you two weeks; a failed production run costs you the container.

What can you compress, and what refuses to move?

Vetting and sampling compress; transit and inspection windows do not. You shorten the front end by arriving with a complete spec pack — drawings, materials, tolerances, packaging and target quantities — instead of discovering them through email over three weeks. You cannot shorten a sailing, and you should not shorten the inspection window. Knowing which documents to request up front removes most of the avoidable back-and-forth.

Where do first-time buyers lose the most time?

Unsettled quantities and unsettled payment terms, almost always. A supplier cannot quote firmly against a moving order size, and a quote built on a quantity you never confirm gets requoted later, restarting the conversation. Settle your volume against typical MOQ ranges early, and agree the payment structure before sampling begins rather than after.

When should you start if you have a fixed deadline?

Work backwards from your on-shelf date, then add a buffer for the two annual slowdowns. Chinese New Year and the Q4 peak both compress factory capacity and book out sailings, so a date that looks comfortable in May is tight in September — planning against the Q4 sourcing timeline is often the difference between arriving early and paying for air freight. Leave room for pre-shipment inspection as well: it sits before your balance payment, not after loading.
