The measurement. On 2026-11-01 we swept the sixteen measured plant profiles for any named manufacturing base outside mainland China, in both English and Chinese wording (Vietnam, Thailand, Malaysia, India, Mexico, Hungary and their Chinese forms), then classified each hit by context so that a country mentioned in a customer list does not count as a base. Result: 5 of 16 name one. Of those five, 1 has a completed building (Champion Asia, Vietnam), 2 are described as under construction (Shengyi and Suntak, both Thailand), and 2 name a country and stop there (Kinwong — Thailand; Glorysky — Malaysia, with no legal entity, address or registration number). 0 of 5 publish a date for first shipment, and 0 of 5 publish a qualification date for a named customer or product class.
What this page is. The five claims side by side with the wording actually on record, the difference between a building and a supply line, five questions that convert one into the other, and what a Vietnamese address does and does not change about origin. It sits behind question 5 of the buyer-questions index, which lists four of the five in a table and links here for the detail.
What it is not. Not customs, tax or legal advice; no forecast of tariff policy; no estimate of how long a plant takes to qualify, because none of the five publishes one and a number invented here would be worse than no number. The five entries are as published on 2026-11-01 and will change with the next filing.
| Plant | What the record says | State | Ship date |
|---|---|---|---|
| Champion Asia SSE 603386 |
“Vietnam phase one: 1.8 million m²/year planned, building complete, equipment being installed and commissioned at year-end, positioned for overseas customer orders.” The profile’s own wording is more cautious still: the building is complete and equipment was being installed and commissioned at the 2025 year-end. Source: 2025 annual report, p33–34. | Building complete, commissioning | None |
| Shengyi Electronics STAR 688183 |
“Chachoengsao in Thailand, the last still under construction.” No layer count, no HDI order and no capacity figure in square metres is published on either language version of the site — which makes the Thai site the one base here with a country, a status and nothing to size. | Under construction | None |
| Suntak | 泰国厂 “under construction — 2–78 layers, 8-order HDI, 200,000 m²/mo planned”, on land of 112,000 m², aimed at server, communications, computer and automotive. The most detailed planned specification of the five, and no construction or production date alongside it. | Under construction | None |
| Kinwong | Thailand appears in a thirteen-factory footprint: Shenzhen and Longchuan in Guangdong, Jishui and Xinfeng in Jiangxi, Jinwan and Fushan in Zhuhai, and Thailand. No status, no capacity, no date; the profile records it as “listed among seven bases without a timeline”. | Named only | None |
| Glorysky | “Three manufacturing bases: Huidong (the registered plant), Huai’an in Jiangsu, and Malaysia.” For the Malaysian base the website gives no legal entity, no address and no registration number — so there is nothing to look up in a registry. | Named only | None |
The other eleven profiles name no capacity outside mainland China at all. This is not a shortlist of the best five or a verdict on the eleven: it is a census of what is said in public, and the five profiles carry their sources field by field. Each of the five links back here from the passage where its overseas base is described.
Five words that get used as if they were one, and the reason a quotation built on the wrong one arrives late. In Chinese sourcing documents the same ladder reads 已签约 (signed) → 已建成 (building complete) → 已试产 (trial production) → 已量产 (volume production), and English summaries collapse all four into “built”.
Each gate can hold for reasons invisible from outside a plant: equipment delivery and vendor commissioning, chemical and wastewater permits, operator hiring curves, and the queue for a customer audit. That is why the useful question is never “is the building finished” but “which gate are you at, and when does the next one close”.
Paste-ready. The order matters: the first two separate a supply line from a construction project, the third tells you whether the site can run the board you are buying, and the last two are what a broker will ask you for anyway.
OVERSEAS CAPACITY — five questions, before a quotation
1. First shipment
The date of the first COMMERCIAL shipment out of [ SITE ],
and the customer it shipped to. A building completion date
is not an answer to this question.
2. Qualification
Which product class, and which customer standard, is the
site qualified to? Provide the first-article and reliability
report reference for the class we are buying.
3. Process scope
Which processes run at [ SITE ]: layer count range, HDI
order, surface finish, impedance test, AOI and electrical
test — and which steps are still performed in China and
shipped in. Be specific about inner-layer fabrication.
4. Contracting, invoicing, shipping
The legal entity that quotes, the entity that invoices, and
the entity named as shipper on the bill of lading. A USCC
for each. If they are three different companies, say so.
5. Origin
The country-of-origin statement that will appear on the
commercial invoice, and the basis for it.
Question 3 is the one buyers skip, and it is the one that decides what you are actually buying. A site that laminates, images, etches, drills and tests can carry the origin argument on its own routing. A site that plates and tests inner layers fabricated elsewhere has a different answer, and the difference is visible only in the process routing — never in a photograph of the building.
Country of origin for customs purposes is a determination about where the goods were produced or substantially transformed. It follows the process routing at that site, not the group’s headquarters, not the brand on the quotation and not the address on the invoice. Four entities have to be kept apart, because sourcing teams routinely treat them as one:
| Entity | What it decides |
|---|---|
| Group / brand | Nothing about origin. A Chinese-listed group with a Vietnamese building still produces Chinese-origin boards in China. |
| Contracting entity | Who owes you, and who you can enforce against. Should be the entity whose USCC appears on the contract and on the deposit account. |
| Producing site | The origin question. Which plant ran your panel, and which steps it performed. |
| Shipper / invoicing entity | What the paper trail says. A Chinese trading arm invoicing for boards made in Vietnam does not make the boards Chinese; a Vietnamese arm invoicing for boards made in China does not make them Vietnamese. |
Export revenue is not foreign production, and the two get used interchangeably in sourcing decks. Shengyi Electronics already books 51.79% of its first-half 2026 revenue outside China — all of it produced in Dongguan and Ji’an, with the Thai site still under construction. A high export share tells you the plant knows how to ship across a border; it tells you nothing about where the board was made.
Two readings of this are common and both are wrong. The first is that a Chinese company with a Vietnamese base is a Vietnamese supplier — the base may be a building with no qualified process, as four of the five entries above show in different degrees. The second is that a Vietnamese base changes nothing until it is fully built — a site can be qualified for a narrow product class long before it is finished, and that narrow class may be exactly yours.
Where to get a written answer rather than a plausible one: in the United States, CBP’s binding rulings are searchable in the CROSS database, and the substantial-transformation test is the frame those rulings apply; in the EU, a Binding Origin Information decision is the equivalent instrument. Neither is a substitute for your own broker, and nothing on this page is customs advice.
The value of a first-shipment date is not the capacity behind it. It is the length of the gap you can plan around, priced against the exposure that gap creates:
Substitute your own three numbers; the multiplication is the whole model. What it shows is why “we are building in Thailand” is worth less than a date: a capacity figure is only money once it is qualified and shipping, and until then the cheapest thing you can buy is the date. An unqualified second site is an option, not a supply line — and an option whose expiry nobody wrote down is priced by the wait.
The five entries are live claims, not verdicts, and the page is built to be corrected. Three sources will move first: exchange filings (Champion Asia reports quarterly on the Shanghai exchange and described the Vietnam building in its annual report; Shengyi files on the STAR Market), environmental approval notices (环评公示) published by the receiving province, which typically precede construction and name capacity, and the plants’ own sites, where a status line changes without an announcement. When any of the five publishes a shipment or qualification date, the profile gets the date and this page gets a line. When a sixth plant names a base, the sweep is re-run — the count on this page is a census of sixteen profiles as they exist on 2026-11-01, not a fixed fact about an industry.
Four lines, if you read nothing else. A base named on a website is a claim; a building is a fact; a first shipment is a supply line — and only the third can carry your volume. 0 of 5 publish a date, which is the most useful number here precisely because it is the question buyers forget until the PO is late. Ask for the gate you actually need: if origin is what you need, the gate is “qualified and shipping from that site”, not “building complete”. And a Chinese plant with a Vietnamese base is not a Vietnamese supplier — check the contracting entity, the shipper and the origin statement, three documents with one answer.
It does not tell you what any of the five will be able to do in 2027, and it deliberately publishes no qualification timeline — the interval varies by product class, customer standard and site, and a number invented here would be quoted back at you as if it were measured. “No date published” is not the same as “no date exists”: a factory may hold a qualification plan internally and simply never publish it, which is exactly why question 1 above asks for it in writing. The census is built from what sixteen profiles record in public, so a group that ships from a base it never names would be invisible to it — an absence of evidence, reported as an absence. And nothing here is customs, tax or legal advice: the origin section describes the questions and points at the instruments, and the answer for your goods comes from a ruling or your broker.
