Taiwan sits close to Vietnam, runs some of the region’s most capable precision manufacturing, and yet a first-time buyer often stalls on the same three questions: which office actually confirms a factory is real, which Taiwanese certification a product needs before it can be sold on, and — because Taiwan is outside RCEP and outside every ASEAN trade agreement — what duty actually applies once the goods reach a Vietnamese port. None of the three has an obvious answer from outside Taiwan.

Finding and checking the factory
Start with Taiwan’s own trade promotion agency directory, then confirm the company against the government’s own company registry — a directory listing and a registry check answer different questions, and neither replaces the other.
The Taiwan External Trade Development Council (TAITRA) publishes a directory of Taiwanese exporters through its Taiwantrade platform, and the Ministry of Economic Affairs’ Government Company Information System (GCIS) is the official registry for confirming a company’s registration status and basic corporate details by name or unified business number. We cover how to work through both steps, plus when a video walkthrough is a reasonable stand-in for a site visit, in finding factories in ASEAN and Taiwan — read that first if you have not already shortlisted or checked a Taiwanese company.
A registry check confirms the company legally exists; it does not confirm the entity you are dealing with is the factory itself rather than a trading intermediary, and it does not confirm the product meets the standard your destination market requires. Both of those are separate steps, covered below.
Which Taiwanese standard applies to your product
The Bureau of Standards, Metrology and Inspection (BSMI), an agency of the Ministry of Economic Affairs, sets and enforces the national standards that determine whether a product needs certification before it can be manufactured for, or sold into, the Taiwanese market — and that certification requirement follows the product, not the buyer’s location.
BSMI runs mandatory certification schemes for a defined list of products, concentrated in electrical, electronic, mechanical and chemical goods judged to carry a safety risk. Two of its main mandatory schemes are Registration of Product Certification (RPC) for electrical and electronic products, and Type Approved Batch Inspection (TABI) for mechanical, chemical, electrical and electronic products; both run on a multi-year validity once granted. Depending on the product’s assessed risk, BSMI can require anything from a documented declaration of conformity up to a full factory inspection before certification is issued.
| Question | Why it matters |
|---|---|
| Is the product on BSMI’s mandatory certification list? | If it is, the factory cannot legally sell it inside Taiwan, and an importer sourcing it for re-export should still confirm which standard the factory built to |
| Which BSMI scheme applies (RPC, TABI, or another) | Each scheme has a different testing and inspection route, and a different validity period |
| Is the BSMI mark or registration number already on the product? | A product certified for the Taiwanese domestic market is not automatically certified to your own destination market’s separate standard |
BSMI certification tells you the factory has met a Taiwanese requirement. It does not tell you the product meets Vietnamese or any third-country standard — those are separate certification tracks, run by your own destination market’s authority, and need to be arranged independently regardless of what BSMI has already certified.

Export documents and who issues the certificate of origin
Taiwan’s certificates of origin are issued by chambers of commerce authorised by the International Trade Administration (formerly the Bureau of Foreign Trade) of the Ministry of Economic Affairs — not by the exporter itself and not by a freight forwarder.
The Taiwan Chamber of Commerce and other authorised local chambers issue the standard Chamber of Commerce Certificate of Origin for general exports. A separate Form A certificate, issued through TAITRA, applies specifically where the destination market grants Taiwan preferential access under its own Generalized System of Preferences (GSP) scheme — this is a destination-country concession, not a Taiwan–Vietnam trade agreement, and whether it applies depends on the destination market’s own rules, not on where the goods are shipped from.
| Document | Who issues it |
|---|---|
| Chamber of Commerce Certificate of Origin | An authorised chamber of commerce (e.g. the Taiwan Chamber of Commerce), under rules set by the International Trade Administration, Ministry of Economic Affairs |
| GSP Form A | TAITRA, where the destination country’s own GSP scheme covers Taiwan |
| Commercial invoice, packing list | The exporting company itself |
Ask the supplier which document it will issue before the first shipment, and confirm the chamber or agency named on the certificate is one of the authorised issuing bodies — a certificate from an unauthorised source is not a valid proof of origin.

Ports and the shipping route into Vietnam
Kaohsiung, in southern Taiwan, is the island’s principal container port and the one most shipping lines route through for Southeast Asia-bound cargo; Taichung and Keelung are the other main container ports, and Taoyuan handles air freight.
Which port a shipment moves through depends on where the factory is located and which shipping line the freight forwarder books, not on a fixed rule — ask the factory which port it normally ships from, since a factory in the north of Taiwan shipping through Kaohsiung rather than the closer Keelung adds inland haulage that should show up as a separate line on the freight quotation.
Duty at the Vietnamese border: there is no Vietnam–Taiwan preferential agreement
Taiwan is not a member of ASEAN, is not covered by any ASEAN free trade agreement, and is excluded from RCEP — so goods imported from Taiwan into Vietnam are ordinarily assessed at Vietnam’s normal (MFN-equivalent) import duty rate, not at a preferential FTA rate.
This is the point most buyers moving from ASEAN or Japan sourcing to Taiwan sourcing miss, because it runs the opposite way from what they are used to: a shipment from Thailand or Korea can usually claim a preferential rate under an ASEAN agreement, VKFTA, AKFTA or RCEP, once the right certificate of origin travels with it. A shipment from Taiwan generally cannot, because no such agreement exists between Vietnam and Taiwan. Build the standard duty rate into the landed cost from the start, rather than assuming a preferential rate that is not available, and confirm the applicable HS code and duty rate with Vietnamese customs or a licensed customs broker before the order is placed.

Putting the process together
Work through these in order before placing the first order.
- Shortlist through TAITRA’s Taiwantrade directory, then check the company against GCIS — see finding factories in ASEAN and Taiwan for the detail.
- Confirm whether your product falls under a BSMI mandatory scheme, and ask what the factory has actually certified to.
- Confirm which document the factory will issue — a Chamber of Commerce Certificate of Origin, or a GSP Form A if your destination market’s own GSP scheme applies.
- Ask which port the factory ships from, and price inland haulage to that port separately if it is not the nearest one.
- Build the standard Vietnamese import duty rate into your landed cost, since no Vietnam–Taiwan preferential agreement reduces it.
Frequently asked questions
1. Can a Taiwanese exporter get a preferential import duty rate into Vietnam through RCEP?
No. Taiwan is not a party to RCEP and is not covered by any ASEAN free trade agreement with Vietnam, so imports from Taiwan are ordinarily assessed at Vietnam’s standard duty rate.
2. Does every product from Taiwan need BSMI certification?
No. BSMI’s mandatory schemes cover a defined list of products, mainly electrical, electronic, mechanical and chemical goods assessed as carrying a safety risk. Ask the factory whether your specific product is on that list.
3. Who issues a Taiwanese certificate of origin?
An authorised chamber of commerce, such as the Taiwan Chamber of Commerce, under rules set by the International Trade Administration of the Ministry of Economic Affairs — not the exporting company itself.
4. Is a company listed on Taiwantrade guaranteed to be the actual factory?
No. The directory confirms the company registered as an exporter with TAITRA. Confirming it is the manufacturer rather than a trading intermediary, and confirming its legal registration, are separate steps — see finding factories in ASEAN and Taiwan.
5. Which Taiwanese port should I expect a shipment to move through?
Most commonly Kaohsiung for Southeast Asia-bound sea freight, though this depends on the factory’s location and the shipping line the forwarder books — ask the factory directly rather than assuming.
