Most foreign buyers approach Vietnam the same way: a promising factory contact, a good price, and then a fog of questions about how the rest actually works. This is the whole process, start to finish, so you can plan it as a sequence rather than improvise it. It applies whether you run it yourself or hand it to a sourcing desk.

The timeline, first

Set expectations before anything else: from first enquiry to materials on site is typically 10 to 16 weeks — production is 2–8 weeks depending on the material, sea freight adds 1–5 weeks by destination, plus sampling and customs. The single most useful thing you can do is work backward from your site date. Our landing planner does exactly that: enter the date you need materials on site and it walks back through vessel loading, ex-factory and order dates.

Stage 1 — Source & sample

Identify real manufacturers (not trading companies — see stage 1b), share a clear specification, and get quotations. Then approve physical samples before anything scales: a benchmark sample against the spec, and a golden sample signed off before mass production so what lands matches what you approved. Request a sample box early; it costs only courier, usually credited back on your first order.

Stage 1b — verify the factory. The defining risk in Vietnam is a trading company presenting itself as a producer. Before money moves, confirm business registration and tax code, demand mill certificates, and either visit or have an agent walk the production floor. A physical visit is known to cut sourcing risk roughly in half. (Full checklist: how to verify a Vietnamese factory.)

Stage 2 — Contract & deposit

Agree terms in writing before a purchase order. Standard payment is 30% deposit by T/T, 70% balance against the bill of lading — never 100% prepayment. Fix the specification, tolerances, AQL quality levels and the remedy for a failed inspection in a Quality Agreement before the PO, not after a dispute. Confirm the receiving bank account is in the company's legal name.

Stage 3 — Produce & inspect

Two inspection points protect you: a during-production check at ~30–40% completion (catches systemic errors early), and a pre-shipment inspection when goods are produced and packed. Independent third-party inspection (SGS, Intertek, TÜV) can be arranged. Crucially, release the balance payment only against a passed inspection — evidence, not promises.

Stage 4 — Ship & clear customs

Choose your incoterm deliberately — FOB, CIF or DDP change who controls freight and risk (see incoterms explained). Your customs entry needs a commercial invoice, packing list, bill of lading and — the one that decides your duty — a certificate of origin matched to the applicable scheme (EUR.1/REX for the EU/UK, form for AANZFTA, etc.). Getting origin right is what unlocks preferential tariffs or, for the US, keeps you on the right side of the reciprocal rate.

Stage 5 — Deliver

Consolidate where you can: shipping several material groups in one container cuts freight and coordination. Then it's port to yard on your incoterm, with the documents your certifier needs already in the package.

The two mistakes that actually hurt

Everything above exists to prevent two errors that are expensive and hard to reverse: paying an unverified advance, and skipping pre-shipment inspection. Do the diligence and keep the inspection, and most horror stories never start.

Where a desk changes the math

Run five stages across a dozen factories in different clusters and time zones, and the coordination is the real cost — not the unit price. A consolidated sourcing desk signs one contract, holds one QC standard, and delivers one shipment plan across all of it. That's the difference between managing a supply chain and having one.

Sources & data notes

This is general procurement guidance based on standard Vietnamese export practice and market-entry advice; timelines, terms and documentary requirements vary by material, factory and destination. Confirm current duty rates, certificate-of-origin requirements and payment terms with a licensed customs broker and your supplier before committing. Not legal or customs advice.
