An RFQ that goes out to ten suppliers and comes back with three vague quotes, two outright declines and five silences is not usually a sign of a bad market — it is usually a sign the RFQ went to the wrong ten suppliers. Here are the specific, recurring reasons that happens, and what a sourcing partner should be doing before an RFQ is ever sent to filter for genuine fit rather than just contact-list coverage.
“Wrong supplier” usually does not mean a scam
It is tempting to read a bad batch of RFQ responses as evidence of an unreliable supplier market. In practice, the far more common cause is a mismatch between what the RFQ asked for and what the recipient actually does, makes, or has capacity for at that moment. A mismatched RFQ still costs real time — every vague or off-spec quote has to be read, clarified or rejected — but the fix is upstream of supplier evaluation: it is sending the request to the right list in the first place.
The time cost compounds quickly on a project with a real schedule. A single mismatched RFQ costs a few days of back-and-forth before it is abandoned; a batch of ten RFQs where six were sent to the wrong type of supplier can cost weeks, since the buyer typically does not find out a given quote is unusable until well into the clarification process, and by then the window to send a replacement RFQ to a better-fitting vendor and still hit the original delivery date may already have closed. The practical upshot is that supplier vetting is not a nice-to-have quality step layered on top of sourcing — on a schedule-driven project, it is what keeps the schedule itself intact.
Trading company vs. manufacturer confusion
A significant share of listings on general B2B directories are trading companies or agents, not the factories that actually produce the goods — and the listing does not always make that distinction obvious. Sending an RFQ that assumes direct factory pricing and factory-level technical answers to what is actually a reseller produces a quote that looks plausible but carries an unknown markup and a second, invisible layer of communication between the buyer and whoever is really making the part. This is not automatically a problem — a well-run trading relationship can still deliver good pricing and service — but the buyer should know which one they are dealing with, since technical questions about manufacturing process, material traceability or production capacity need to reach an actual factory to be answered accurately.
The vendor’s real specialization doesn’t match the spec
Broad category listings hide a lot of specialization detail. A company listed under “pipeline equipment” might specialize in butt-weld fittings and have never forged a flange; another might build cast valve bodies but have no in-house forging capacity for a fitting spec that calls for it. Because these products often sit next to each other on a buyer’s bill of quantities, it is easy to assume they come from the same type of factory — they frequently do not. An RFQ sent without checking the vendor’s actual production method against the standard being requested (forged vs. cast, seamless vs. welded, machined vs. fabricated) routinely reaches a company that could technically reply, but would be sourcing the item from a third party itself rather than manufacturing it — adding a hidden layer the buyer thought they had avoided by going to a “manufacturer” directly.
Capacity mismatch: too small, too large, or too specialized
Fit is not only about product type — it is also about whether the quantity and timeline in the RFQ suit how the vendor actually runs its production floor. A large, export-focused factory may give a slow, unenthusiastic response to a request for a handful of pieces, since a small order does not justify opening a production run at a competitive price. Conversely, a smaller workshop capable of excellent quality on a modest order can be the wrong choice for a large multi-hundred-piece requirement with a fixed delivery date, simply because it lacks the parallel capacity to hit that volume on schedule. Neither vendor is a bad supplier in the abstract — each is a mismatch for that specific RFQ’s scale, which only becomes visible once someone actually checks production capacity against order size rather than sending the same RFQ to every name on a list regardless of typical order profile.
Geography, language and Incoterm familiarity mismatches
A vendor can be a genuinely good manufacturer and still be a poor fit for a specific buyer because of gaps that have nothing to do with production quality. A factory accustomed to domestic sales may have never quoted an export shipment on Incoterms® 2020 terms before, and can misquote the point at which risk and cost transfer, or omit export packing and documentation costs entirely because it has never had to price them. A time zone gap of eight hours or more turns a same-day technical clarification into a two-day exchange, which is manageable for a single RFQ but becomes a serious drag across a multi-vendor project running on a fixed schedule. None of this means the vendor cannot ultimately deliver a good product — it means the RFQ process itself will take noticeably longer and carry more room for misunderstanding on commercial terms, which is worth knowing before committing to a delivery date that assumes smooth, fast communication.
No spec cross-check before the quote goes out
The most costly version of a wrong-supplier RFQ is the one that comes back looking right. A vendor unfamiliar with a specific standard’s exact requirements can quote a product that resembles the specification closely enough to pass a quick review, while differing on a detail that only surfaces at inspection or during installation — a pressure class, a facing type, or a material grade substituted for something “equivalent.” This is less a supplier-selection problem than a quote-review problem, but the two compound each other: a vendor genuinely unfamiliar with the standard is also the one least likely to flag its own quote as a partial match, since it may not fully recognize the gap itself.
How a sourcing partner filters for fit before an RFQ goes out
The fixes for all of the above happen before quotes are requested, not after they come back. A sourcing partner maintaining verified manufacturer relationships should be able to say, before an RFQ is sent:
- Whether each recipient is the actual manufacturer or a reseller, and disclose that distinction to the buyer up front
- Whether the recipient's production method (forged, cast, seamless, welded, machined) matches what the specification actually requires
- Whether the requested quantity and delivery date suit that vendor's typical order size and current production load
- Which vendors on the list have a demonstrated, recent production reference for the exact standard and class being requested
- Whether returned quotes are checked line-by-line against the requested standard before being passed to the buyer, not simply forwarded as received
This filtering is most of what separates a sourcing partner worth using from a simple RFQ-forwarding service — the value is in knowing, ahead of time, which of dozens of possible recipients actually fit a given request. Oillinko circulates every RFQ only to manufacturers already vetted against this kind of fit, and checks every returned quote against the requested standard before it reaches the buyer. Send us your specification and we will tell you plainly if something in it does not match what a given vendor actually builds, rather than passing along a quote that only looks right. If your project spans several vendors at once, see our guide to consolidated shipments and multi-vendor orders for what happens after the right suppliers are found.
Frequently asked questions
Is a supplier who can't quote my spec necessarily acting in bad faith?
Usually not. Most mismatched RFQs land on a genuine manufacturer who simply doesn't build the item in question, or doesn't hold the specific standard qualification asked for — for instance a valve factory receiving a request for forged fittings. Bad faith exists in the market, but a slow reply, a vague quote, or a polite decline is far more often just a capability mismatch than a deliberate misrepresentation.
How can a buyer check a vendor's real specialization before sending an RFQ?
Ask directly for reference production of the exact item and standard, not just the product family — a company that makes valves does not automatically forge fittings, even though both might appear under 'pipeline equipment' in a directory listing. A specific, recent production reference for the same standard and size range is a stronger signal than a general capability statement.
Why would a large factory ignore or deprioritize a small RFQ?
Manufacturing capacity is finite and factories naturally prioritize orders that make efficient use of a production run — a request for a handful of pieces can sit behind a queue of larger orders, or get quoted at a price that reflects the factory's lack of interest rather than the item's real cost. This is less about the buyer being unimportant and more about how a factory schedules its floor.
Does going through a sourcing partner guarantee a better-fit supplier?
It shifts the vetting work rather than eliminating the need for it. A sourcing partner that actually maintains verified manufacturer relationships and checks quotes against the spec before passing them on removes most of the mismatch risk described here; one that simply forwards an RFQ to whichever contacts it has on file does not add much beyond what a buyer could find with their own search.
