The most common planning mistake in Vietnam sourcing is treating "lead time" as one number. It's a stack of them — sampling, production, freight, customs — and each varies by material and destination. Here are realistic figures so you can build a schedule that holds.
Production time, by material group
Production is the part buyers most often underestimate, because fabricated items are made to your specification, not pulled from stock:
| Material group | Typical production |
|---|---|
| Fiber cement board | 2–4 weeks |
| Porcelain & large-format tile | 2–4 weeks |
| Sanitary ware | 3–5 weeks |
| Engineered quartz (cut-to-size) | 3–5 weeks |
| Wood & plywood | 3–5 weeks |
| Aluminium & glass (fabricated to schedule) | 5–8 weeks |
Complex, engineered items — curtain wall, cut-to-size stone — sit at the long end because there's design and fabrication before anything is made. Standard board and tile are quick.
Sea-freight transit, by destination
Add ocean transit on top. Rough door-relevant sailing times from Vietnam:
- Australia / New Zealand: ~1–2.5 weeks (the shortest lanes we serve).
- Intra-Asia (Japan, Korea, Singapore): ~1–2 weeks.
- US West Coast: ~2.5–4 weeks · US East Coast: ~4–5 weeks.
- North Europe / UK: ~4–6 weeks — the lane most exposed to Red Sea routing, so pad it.
- Middle East (Gulf): ~2.5–4 weeks.
Then allow roughly a week either side for port handling and customs clearance.
The one date that breaks schedules: Tet
Vietnam's factories effectively stop for the Lunar New Year (Tet) — around 10–14 days of shutdown plus a slow restart, which removes 2–3 productive weeks from any February window. If your program touches Q1, plan around it deliberately (full detail: the Tet production calendar). China's New Year is the same week, so anything with Chinese inputs slows too.
How to plan it: backward, and consolidated
Two habits keep a tight program on track:
- Work backward from the site date. Start at "materials needed on site," subtract customs, subtract transit for your port, subtract production for the slowest item in the package, and you have your order-by date. The landing planner automates exactly this.
- Consolidate groups. Shipping several material groups in one container doesn't just cut freight — it synchronises arrival, so your site isn't waiting on the one group that shipped separately.
The buyers who miss dates are almost always the ones who planned forward and optimistically. The ones who hit them planned backward with the slow item and Tet already in the math.
Sources & data notes
Production ranges are typical for the six groups we source; transit times are indicative sailing estimates that vary by carrier, service and season, and exclude the current Red Sea volatility on the Europe lane. Confirm the actual lead time for your specific items and port with the supplier and your forwarder before committing to a site date. For planning only.
