Sourcing EDC parts from Vietnam vs China: what actually differs

We source in Vietnam, so read this with that in mind. But the honest comparison is more mixed than either country’s marketing suggests, and pretending otherwise wastes your time.

Where they are basically equal

Machine capability. Both countries have plenty of shops running good Japanese and Taiwanese machining centres with the tolerance capability EDC needs. Neither has a monopoly on precision. The variation between individual shops within either country is far larger than the variation between the countries.

Price at the machine. For a titanium scale at 100 pieces, quotes are close. Vietnam is sometimes slightly cheaper on labour-heavy operations, China sometimes cheaper on material.

Where China is genuinely stronger

Material availability. This is the real advantage and it is significant. Exotic alloys, unusual plate thicknesses, specific tempers — a Shenzhen or Dongguan shop can often source in days what a Vietnamese shop needs two or three weeks to import. If your design needs 7075 in a non-standard thickness, or zirconium, or a specific Damascus, China will usually be faster.

Finishing depth. More specialist finishers within a short drive: PVD houses, specialist anodizers, platers. Fewer handoff delays when a part needs three processes.

Supplier density. More shops to choose from, which means more chance of finding one that fits an unusual requirement exactly.

Where Vietnam is genuinely stronger

Appetite for small batches. This is the one that matters most for EDC. Many Chinese shops that built their business on volume treat a 50-piece order as an inconvenience, and it shows in the attention it gets. Vietnamese shops are on average smaller and more willing to treat a small order as a real customer. That is a generalisation with plenty of exceptions, but it is the pattern we see.

Tariff position for US buyers. Section 301 tariffs apply to a broad range of Chinese-origin goods and not to Vietnamese-origin. Depending on your HTS classification this can be a material percentage on landed cost. Check your own classification rather than taking anyone’s word for it, including ours — but if you have not checked, it is worth an afternoon.

Concentration risk. If your entire supply chain is in one country, a policy change or a port problem stops your whole business. Many brands we talk to are adding a second country rather than switching, which is a more sensible framing than a migration.

Communication. Roughly comparable in practice, though English is broadly taught in Vietnamese technical education and time-zone overlap with the US is similar for both.

Where Vietnam is genuinely weaker

Depth of the supply chain. Fewer specialist processes available domestically. Heat treatment, PVD and unusual finishes sometimes mean a longer handoff or a sub-supplier further away. Lead times reflect that — see heat treatment for what that does to a schedule.

Material lead time for anything unusual. Common 6061, titanium Grade 5 and 304 are stocked. Beyond that, expect to wait.

Scale ceiling. For a 50,000-piece order with aggressive pricing, China’s volume infrastructure is hard to beat. Vietnam is not the right answer for every job and we will say so.

The decision that actually matters

Not the country. The shop.

A good shop in either country beats a bad one in the other by a wide margin, and the variables that predict a good outcome are the same everywhere: does it run your material weekly, does it answer email in a day, does it tell you when something on your drawing is a bad idea, and has it done work at your batch size before.

That is what our vetting looks for, and it is what you should look for whether you work with us or not. Send a drawing and we will tell you honestly if Vietnam is the wrong place for that part. Related: why 25 pieces costs more than a quarter of 100.

Payment and commercial terms

Broadly similar in both countries, with some differences worth knowing.

Typical terms for a new customer: 50 percent deposit, 50 percent before shipment. After a few successful orders this often moves to 30/70 or net terms.

Payment method. Telegraphic transfer is standard in both. Chinese suppliers more commonly accept Alipay and trade-platform escrow; Vietnamese suppliers are more likely to want a straight bank transfer. Bank fees on small orders are a real cost — consolidating two small orders into one payment saves more than people expect.

Currency. Quotes in both countries are usually in USD for export work, which removes exchange risk from your side.

Trade platform escrow protects a first transaction but adds fees and a layer of intermediation. For a relationship you intend to keep, direct terms after a successful small first order is the normal path — which is another argument for starting with something small. See lanyard beads and small turned parts.

Logistics in practice

Air freight from either country to the US or EU runs three to seven days door to door via DHL or FedEx. For EDC batch sizes — a box of 200 titanium scales weighs very little — air is usually the right answer and the cost difference between the two countries is marginal.

Sea freight matters only if you are shipping real volume. China’s port infrastructure and sailing frequency are better. Vietnam’s are adequate and improving.

Customs. Straightforward from both. Get the HTS classification right, because it determines duty and, for US buyers, tariff exposure. A customs broker’s opinion on classification costs little and is worth having before the first shipment rather than after.

Express, air and sea are compared in shipping EDC drops from Vietnam.

Communication patterns

The honest picture, from working in it:

Response times are broadly comparable and driven by the individual shop rather than the country. Written English is generally good in both at the level needed for technical exchange; spoken English varies more.

One real difference: Chinese New Year shuts Chinese manufacturing for roughly two to three weeks, with a ramp-down before and a slow ramp-up after that can extend the effective disruption to a month or more. Tet in Vietnam does the same thing at roughly the same time of year.

Both matter for your schedule. If you have a Q1 drop, place the order in November, not January. This is the single most common avoidable schedule failure we see.

Intellectual property

Both countries have IP law, and enforcement in either is slow and expensive for a small brand.

Practical protection is contractual and relational rather than legal: an NDA with a non-manufacture clause, a supplier with a reputation to protect, and not sending your entire product to a single supplier who could assemble and sell it. See NDA, IP and tooling ownership.

The reputational point is underrated. A shop that has built an export business on Western customers has far more to lose from copying you than a shop taking its first international order.

Dual sourcing as the realistic answer

Most established EDC brands we talk to end up with more than one supplier, and frequently in more than one country.

The reasoning is not usually price. It is that a single supplier is a single point of failure for the entire business, and the cost of qualifying a second one is much lower when you are not doing it in a panic.

If you are currently single-sourced in China, qualifying a Vietnamese shop on one part is a modest investment against a real risk. If you are single-sourced in Vietnam, the same argument runs in reverse.

FAQ

Is quality lower in Vietnam? No. Individual shop quality varies enormously within both countries and the distributions overlap almost entirely. The question is always about the specific shop.

Is Vietnam cheaper? Sometimes, marginally, on labour-intensive operations. Not reliably, and not by enough to be the deciding factor. Tariff position is a much larger number for US buyers than the quote difference.

Do I need to visit the factory? Not for a first small order. Worth doing before committing to a significant volume relationship. A video call walking the floor is a reasonable substitute and any serious shop will do one.

What about India, Taiwan or Eastern Europe? Taiwan is excellent for precision and priced accordingly. India is growing and stronger in some sectors than others. Eastern Europe suits EU buyers on lead time and tariffs. None are wrong; they are different trade-offs.

How do I verify a shop is real? Business registration documents, a video call from the shop floor showing the machines in your quote, references from existing export customers, and a small first order. In that order.

Can you source in China too? Our network is in Vietnam. If a part is genuinely better made elsewhere, we will say so rather than push it into a shop that will struggle. Send the drawing and you will get an honest answer.
