How to Write an RFQ Taiwan Suppliers Actually Answer

July 17, 20265 min read

Most RFQs sent to Taiwan factories never get a real reply — not because the factory doesn't want the business, but because the request doesn't give them enough to work with. A sourcing manager on the receiving end triages dozens of inbound emails a week, and an RFQ missing quantity, spec or Incoterm gets a form reply or silence, not a quote. This is a field-by-field guide to writing the kind of RFQ that gets read, understood and answered — plus the mistakes that reliably kill a reply rate, and a skeleton you can copy for your next request.

Why incomplete RFQs get ignored

A factory's sales or engineering team has to do real work before they can quote: check tooling availability, estimate cycle time, price materials, confirm a production slot. An RFQ that's missing quantity or spec forces them to either guess — risky for them — or write back asking for the missing pieces, which is slow for you. Busy suppliers, the ones worth working with, triage for completeness before anything else, because a complete RFQ signals a buyer who has done the homework and is likely to actually place an order.

The fix isn't a longer email. It's a structured one. A short RFQ that covers every required field beats a long one that rambles and still leaves gaps.

Field by field: what a complete RFQ contains

Work through these fields in order. If you can't answer one yet, say so explicitly rather than leaving it blank — "TBD, will confirm after sample" is more useful to a factory than silence.

Part description — vehicle make, model, generation and year range, plus position (front/rear, left/right, upper/lower). Skip OE and cross-reference numbers at this stage; a plain-language description is enough to start, and it keeps sensitive reference data out of a cold email.
Quantity — both your pilot quantity and your realistic annual volume. These are different numbers and a factory prices them differently; conflating them produces a quote that fits neither.
Specifications — material, tolerance, surface finish, and any performance requirement you already know, even approximately. "Not sure yet" is fine for one or two fields, but say so rather than omitting them.
Incoterm — FOB, EXW, CIF or another term, and the port or city you're quoting to. A unit price without an Incoterm isn't comparable across suppliers.
Acceptance criteria — how you or your customer will judge whether a delivered part passes: dimensional tolerance, a physical fit test against a reference part, a certification requirement, or a named inspection standard.
Certifications required — and whether you need test reports or certificates submitted with the quote itself, not just claimed in conversation.
Timeline — separately, for samples and for production. A factory that can sample in two weeks and produce in eight is answering a different question than one asked for a single combined date.
Packaging and labeling — export carton requirements, private labeling if any, and any market-specific labeling rule you already know about.

Common mistakes that kill a reply rate

The same handful of habits show up in almost every RFQ that goes unanswered.

Sending a one-line "please quote" with an attached photo and nothing else — there's not enough here to price anything
Bundling ten unrelated parts into a single message with no per-part breakdown, which forces the factory to do your organizing work before they can start theirs
Leaving out both pilot and production quantity, so the factory has to guess which one you actually want priced
Asking for exclusivity or a long-term commitment before a single sample has shipped
Omitting a reply-by date, so your request sits in a queue behind requests that gave one

A sample RFQ skeleton

You don't need special software for this — a short, structured email or a one-page attachment works. Here's a skeleton to adapt:

Part: [vehicle make/model/generation/year range], [position]
Pilot quantity: [n] units — Production volume (annual estimate): [n] units
Material / spec: [known specs, or "TBD — please advise typical options"]
Incoterm: [FOB / EXW / CIF] to [port or city]
Acceptance criteria: [dimensional tolerance / fit test / certification / inspection standard]
Certifications required: [list, or "none required"]
Sample timeline needed by: [date] — Production timeline needed by: [date]
Packaging: [export carton / private label / market labeling notes]
Reply needed by: [date]

What happens after you send it

A complete RFQ to a genuinely capable factory typically gets at least an acknowledgment within a few business days, even if the full quote takes longer while they check tooling or material cost. If a week passes with no reply at all, a short, polite follow-up referencing your original email is normal practice — it isn't pushy, and factories that intend to quote generally appreciate the nudge. If you're sending the same RFQ to several factories at once, say so; it's common practice and most suppliers expect it, but it helps them prioritize honestly.

Our guide on sourcing aftermarket parts from Taiwan walks through the steps before and after the RFQ — from identifying the right factory to running a pilot before committing to volume — and our piece on OE cross-reference numbers explains why it's worth holding those numbers back until you're further into the conversation.
