When a Quote Is Half the Market Price: Questions to Ask Befo

When a Quote Is Half the Market Price: Questions to Ask Before You Pay for an Industrial Automation Part

By the aoctrl sourcing desk · supply-chain desk · as of September 2026 We are an independent industrial automation distributor and sourcing agent operating from China — not a franchised channel, not an OEM, not a reseller with a brand badge. Buyers reach us when a line item on a quote, a BOM, or a single replacement request lands in their inbox at a number that looks too good. That is the right place to start. The price is the signal. The part behind it is the question. This article walks through how we read a too-cheap offer, what we verify before we put a rupee, a rouble, a dollar, or a yuan on a wire, and the questions we ask on the buyer's behalf when a single line on a quote looks like it could save twenty percent — or cost twenty times more.

If you have already received one such quote, here is the direct answer. A quote that lands at less than roughly half of what the authorized channel, three independent distributors, and the major catalog houses are all printing for the same MPN is, in our experience, one of four things: a different part being mislabeled as the one you asked for; a used or refurb lot being sold as new; a counterfeit or remarked unit presented as factory-sealed; or an offer that simply will not be honored at the price quoted once the wire lands. The right first move is not to argue the price — it is to slow the transaction down and ask for the documents, the markings, and the photo record that prove the line is the line. We treat this as a routine step on every quote, not an exception.

Why a Too-Low Price Is a Symptom, Not a Bargain

The first thing to understand about industrial automation pricing is that it is layered, not flat. A Siemens Sirius contactor, a Schneider TeSys D LC1D module, an Omron E3Z photoelectric sensor, a Phoenix Contact QUINT power supply, or a Yaskawa Sigma-7 servo amplifier has, in the legitimate market, a relatively narrow price band at any given moment. Several reference points shape that band: the authorized-channel list price, the catalog price on the major online stockists, the OEM list price (which is what the OEM itself publishes for the channel to anchor against), the auction and liquidation price for the same MPN pulled from decommissioned equipment, and the broker price for the same MPN moved through a trader network. When you see all five numbers within a tight range and then a sixth number landing at forty, fifty, or sixty percent below the low end of that range, the sixth number is the one that needs explaining — not the other five.

That does not mean a low price is always wrong. It means a low price without a story is wrong. A genuine new-surplus line pulled from a closed production line in Shenzhen has a legitimate reason to be priced below the franchised channel: the OEM no longer channels it, so there is no authorized margin layer, and the inventory holder is closing a position. A refurbished unit from a workshop that has bench-tested the line, recorded the test, and is willing to put a written per-line warranty behind it has a legitimate reason to be priced below the new unit: it is not the new unit. A pulled-from-machine used unit with a clear provenance, no refurb claim, and a low price that reflects the absence of any warranty, has a legitimate reason to be priced below the new unit: it is used. None of these stories are scams. They are exactly the conditions that our catalog operates under — we hold new surplus, we hold refurbished lots that have been bench-tested per the published procedures on our quality page, and we hold used lots that are sold as used and priced as used. What is a scam is selling a used or refurbished unit as new at a new-channel price. What is also a scam is selling a counterfeit or remarked unit as factory-original at any price.

So the price itself is not the problem. The price without the corresponding document, marking, condition declaration, and provenance trail is the problem.

The Four Things a Too-Low Quote Usually Turns Out to Be

Over the past several years, we have seen enough too-low quotes that we can group them into four buckets. The buyer rarely sees which bucket they are in until the goods arrive or the warranty claim is filed, which is why the questions below exist.

The first bucket is a different part mislabeled with the MPN you asked for. The most common form is a compatible-but-not-identical substitute: a unit that fits the same socket or accepts the same wiring but is a different series, a different firmware revision, a different output characteristic, or a different agency certification. Another common form is a previous-generation unit that looks identical from the outside and accepts the same program but behaves differently under fault conditions, under load, or under extended temperature. A buyer who orders a Schneider LC1D32 contactor and receives an LC1D25 does not usually notice the difference on the invoice — the markings on the device tell the truth, but the markings are also the easiest thing to relabel.

The second bucket is a used or refurbished unit sold as new. The unit may actually be the correct MPN, may actually fit the machine, may actually pass a quick power-on check, and may even carry a counterfeit date code or a re-stamped lot code. The price drops because the cost basis dropped: the part was pulled from a decommissioned line, the cosmetic condition was cleaned, the warranty was not extended, and the unit is being resold at the price the cost basis supports. The buyer sees a low number; the seller sees the cost basis. Both can be honest about the transaction, but only if the condition disclosure is honest.

The third bucket is a counterfeit or remarked unit. This is the bucket the buyer should be most concerned about, because the unit may carry the original MPN, the original-looking label, and may look right at a glance, but it has been built from a different BOM, a different process, or with components salvaged from discarded units. A counterfeit safety relay in an e-stop circuit, a counterfeit motor protector in a pump station, a counterfeit sensor on a sorting line, is not a thirty-percent savings. It is a foreseeable failure. It is also the bucket where the failure mode is most often invisible at acceptance and most expensive at commissioning.

The fourth bucket is an offer that will not be honored at the quoted price. The seller publishes a number, accepts an order, accepts a payment, and then either substitutes a different line, ships a partial shipment, adds surcharges after the fact, or simply stops responding once the wire clears. This bucket is not about the part at all. It is about the transaction. The cheapest signal for this bucket is a quote that comes from an unverifiable entity, asks for full payment up-front by an irreversible channel, and refuses to provide any per-line document.

The Documents and Markings We Ask For Before We Touch a Too-Low Quote

Before we accept a too-low line into our procurement chain, we ask the upstream holder for the same set of items we would ask for on any quote. The list is not exotic. It is the same list we publish on our quality page and the same list any buyer should be able to ask for without friction.

For the line itself, we need a photo of the device label, showing the MPN, the serial or lot code, the date code, the agency marks (CE, UL, CCC, EAC where applicable — we do not issue any of these, but we read them), and the hardware or firmware revision if it is printed on the label. We need a second photo of the device from a different angle, showing the connector layout, the terminal markings, and any sealed or conformal-coated surface. For a module that carries firmware, we need a screenshot of the diagnostic or version-readout screen, captured with the device powered, that shows the firmware string. For a contactor or a relay, we need a photo of the contact tips if they have been used.

For the lot, we need the invoice or receipt trail back to the point where the lot was sourced — not necessarily with every intermediary named, but with enough provenance that we can answer the question "where did this come from" without inventing the answer. For a closed production line, that means a record from the line closure or the inventory disposal. For a pulled-from-machine lot, that means a record of which machines, which sites, and which decommissioning contractor. For a refurbished lot, that means the bench-test record per line, with the test procedure named, the pass criteria stated, and the date and operator signed.

For the condition, we need the condition written on the quote line, not just inferred. New surplus, refurbished, and used mean three different things and carry three different prices. A quote that lists only a price and an MPN, with no condition column, is not a quote we can put a payment behind.

For the transaction, we need to know who we are paying, on what terms, and through what channel. The payment terms we accept on too-low lines are not the same as the payment terms we accept on a normal-line quote. We do not pay full up-front by an irreversible channel for an unverified line, and we do not ask a buyer to do so either. We split the payment, we use a verifiable channel, and we keep the document trail alongside the line.

What the Buyer Should Ask the Seller — and What the Seller's Response Tells You

If a buyer receives a too-low quote directly from a seller they have not worked with before, the questions below are the ones we ask on our own procurement when a line lands below the market band. The buyer's questions should be the same.

Ask for the line's photo record before payment. A seller who refuses to send a single photo of the device label, before payment, is not a seller we are willing to transact with. A seller who sends a photo of a box, but not of the device, is sending the same signal. A seller who sends photos of a device but cannot produce a photo of the actual unit being shipped — for example, photos that match the listing but not the lot — is sending the third signal. None of these responses are proof of misconduct. They are proof that the seller is not yet in a position to be paid for the line at hand.

Ask for the condition in writing on the quote. The quote line should read something like "new surplus, factory-sealed, date code 2024 Q1" or "refurbished, bench-tested per procedure, 90-day limited warranty" or "used, as-pulled, no warranty." If the quote reads only an MPN and a price, with no condition, the seller has not yet decided what they are selling. The buyer cannot decide whether to buy until the seller has.

Ask for the lot provenance. Where was the lot sourced? When? By whom? If the seller cannot answer without referring the buyer to a third party they will not name, the line is not yet ready for a payment.

Ask for the bench-test record if the condition is refurbished. The record should name the inputs that were applied, the outputs that were checked, the pass criteria, and the date. If the seller cannot produce the record, the price is not a refurbished price; it is a used price sold as a refurbished price.

Ask for the payment terms. A quote that requires full payment by an irreversible channel — wire to a personal account, cryptocurrency to a wallet that does not match the entity name, or a payment platform outside the seller's registered business — is not a quote we proceed with. We pay by bank transfer to a registered entity, against a proforma invoice, with the entity name matching the entity name on the quote. We accept letters of credit on larger lots.

Ask for a reference. A seller who has shipped to known buyers in the buyer's region, at a known volume, over a known period, is a different seller from one who cannot name a single reference. A reference is not a guarantee. It is a counterparty signal.

A seller who answers all of the above with documents, photos, condition in writing, lot provenance, bench-test record, payment terms that match the entity, and a verifiable reference, is a seller whose too-low quote may actually be a real line at a real price. That happens. It is rarer than the marketing suggests, but it happens. We have bought from such sellers, and we have resold such lines under the condition stated on the original quote, with the documents we received from the upstream holder.

What We Will Not Do on a Too-Low Line

There are some things we will not do even when the seller answers every question above, and the buyer should know the same limits apply to them.

We will not certify a part as factory-original on the buyer's behalf. We can document the markings, the firmware readout, the date code, the agency marks, the cosmetic condition, and the bench-test result. We cannot certify that any of these is genuine; only the OEM can do that. If a buyer requires an OEM-issued certificate of conformance or an OEM-issued letter of authenticity, the line is not for us. The buyer needs the franchised channel for that line.

We will not warrant a line above the condition stated. A refurbished line carries the refurbished warranty we publish on the quote. A used line carries no warranty unless the quote says otherwise. A new-surplus line carries the manufacturer's residual warranty if any remains; otherwise the warranty is the new-surplus warranty on the quote. We do not back-stop a used line with a refurbished warranty; the condition and the warranty have to match.

We will not ship to a destination we cannot screen. We screen end users and end uses, classify before quoting, and decline transactions that cannot be screened. A too-low quote that asks for a destination we cannot classify, that asks for an end use we cannot verify, or that asks for a routing we cannot justify, is not a line we ship. The buyer should apply the same screen before they pay.

We will not accept a payment that does not match the entity on the quote. The entity on the proforma invoice, the entity on the bank account, the entity on the shipping documents, and the entity named on any agency registration, have to be the same entity. If they differ, the transaction is not yet ready to be paid.

When the Too-Low Quote Is Actually the Right Quote

There is a category where a low quote is the correct quote and where the buyer's instinct to push back is wrong. We see it most often on lots that have been pulled from a closed line, lots that have been written off by the franchised channel, and lots that carry a condition the franchised channel does not stock.

A closed production line in the Pearl River Delta or the Yangtze Delta will, on the day the line stops, release the entire residual inventory — every MPN, every spare, every partial reel, every service unit, every engineering sample — into the secondary market at once. The lot is large, the lot is real, and the lot is sold at the price the cost basis supports. The franchised channel cannot stock these lots because the channel does not exist for an EOL MPN; the catalog houses may list a price, but the lot is in the secondary market. A buyer who needs that MPN, at that moment, has only the secondary market. The price is not too low. The price is the price.

A written-off lot from a system integrator who has gone out of business follows the same pattern. The inventory is sold to clear the estate; the price is set by the estate, not by the channel. A buyer who needs a specific MPN from that integrator's build finds the lot in the secondary market.

A pull from a machine that has been decommissioned, where the parts are sold as-pulled with no warranty, is the same pattern at a smaller scale. The price is low because the cost basis is low. The condition is used. The buyer who needs the part for a non-critical application, or for a machine that is itself approaching end-of-life, is the right buyer for that line.

In each of these cases the buyer's question is not "is the price too low" but "is the line right for my application, at this condition, at this price, with this document trail." That is the question to ask. The price is a piece of information; the line is the answer.

What This Means for a Quote You Hold Right Now

If you are holding a quote right now that looks too good, slow the transaction down. Ask for the line's photo record, the condition in writing on the quote, the lot provenance, the bench-test record if the condition is refurbished, the payment terms, and a reference. Compare the answer against the documents you have on every other line on the quote. If the too-low line is the only line that comes back with thin documentation, the price is not the issue — the line is the issue.

If you do not have the time or the in-house capacity to run the check yourself, send the quote to us. We will read it line by line, flag the lines that look off, ask the upstream holder for the documents above, and report back with a per-line reading. If the line turns out to be real, we will source it on your behalf and resell it under our quote, with our document trail attached. If the line turns out to be wrong, we will tell you which bucket it falls into and what the next step is — including, in some cases, telling you not to buy the line at any price.

Send the quote through the inquiry page or the procurement page. We will respond with a per-line reading, not a sales pitch.

FAQ

What should I check first when a quote comes in far below the market price?

Ask for a photo of the device label, the firmware readout, and the date code, before any payment. A seller who cannot produce those three items on request is not yet ready for the transaction to clear, regardless of the price. The label photo should show the MPN, the agency marks, the hardware or firmware revision, and the lot code.

Is a low price always a sign of a counterfeit or used part being sold as new?

No. A low price can be legitimate when the lot came from a closed production line, a written-off integrator, or a decommissioned machine, and the condition is stated on the quote. The price is a signal; the condition in writing, the lot provenance, and the bench-test record are the verification. If all three are present, the price is not the issue.

How do I tell a refurbished part from a used part being sold as refurbished?

Ask for the bench-test record. The record must name the inputs applied, the outputs checked, the pass criteria, and the date and operator. A used part sold as refurbished carries either no record or a record that does not name any of those four items. The price difference between used and refurbished is the cost of that record plus the cost of the test time.

Can a Chinese distributor offer a real OEM factory-original part at a price far below the franchised channel?

Sometimes, on lots that the franchised channel no longer stocks: closed-line inventory, written-off integrator stock, and decommissioned-machine pulls. In those cases the part is real, the condition is stated, and the price reflects the cost basis. The verification is the same: photo of the label, condition in writing, lot provenance, and bench-test record where the condition is refurbished.

What documents should accompany a quote line for a used or refurbished lot?

The quote line itself should state the condition (new surplus, refurbished, or used), the warranty, and any pass criteria. The photo record should show the device label, the second-angle photo, and any firmware readout. The lot provenance should answer where, when, and from whom the lot was sourced. For a refurbished lot, the bench-test record should name the procedure, the inputs, the outputs, the pass criteria, and the date.

Should I pay in full up-front on a too-low quote?

No. A too-low quote is exactly the line where the terms should be conservative: split payment, verifiable channel, entity name matching on the proforma invoice, the bank account, and the shipping documents. A seller who insists on full up-front payment by an irreversible channel on a too-low line is sending a signal that the transaction is not yet ready.

What is the cheapest way to find out whether the too-low line is real?

Send the quote to an independent sourcing desk and ask for a per-line reading. The reading should cover the four buckets the price could fall into, the documents that confirm or deny each bucket, and the recommended next step for the line. The reading should not be a sales pitch for the desk's own catalog; it should be a per-line assessment of the quote in hand.

Data Notes

The four-bucket framework described in this article (different-part mislabeled, used-as-new, counterfeit or remarked, offer-not-honored) reflects the failure modes observed on procurement lines that arrive at the sourcing desk from the secondary market. The verification sequence (photo of the device label, condition in writing on the quote line, lot provenance, bench-test record where the condition is refurbished, payment terms tied to a verifiable entity) is the sequence the desk applies on every quote line, not an exception. The pricing band reference points (franchised channel, catalog houses, OEM list, auction and liquidation, broker networks) are the layers the desk reads when assessing whether a single line is below market.

The Schneider Electric catalog lines referenced as examples (the TeSys D LC1D contactor family, the Altivar ATV320 variable frequency drive family, and the Zelio RXM relay family) are cited as known MPN families the desk regularly transacts in. Specific stock, price, and lead time are quoted per order on the proforma invoice; this article does not state inventory levels, prices, or delivery times for any specific MPN. The TeSys, Altivar, and Zelio names are trademarks of Schneider Electric; they are used here as factual reference points for product families, not as an authorization claim.

The Substitution Axes That Decide Whether a Substitute Lot Is Actually the Lot You Want

When a quote line looks too low because the seller is presenting a substitute lot as the line you asked for, the verification of the substitute has to be done against the original manufacturer datasheet and your own qualification process. We do not certify that any substitute is equivalent to the original; we read the data and report what we find, including the axes where the manufacturer does not publish a figure. At minimum we check five axes before we put a payment behind a substitute line. The first axis is form, fit, and outline — mounting style, DIN-rail clip, panel cut-out, module width. The second is the electrical ratings — supply voltage, current per channel, inrush, short-circuit behaviour. The third is the function and I/O map — channel count, digital input versus digital output assignment, analog range and resolution. The fourth is the firmware and hardware revision — function state, GSD or EDS file revision, project file portability. The fifth is the communication protocol — Profibus, Profinet, EtherNet/IP, EtherCAT, Modbus, or vendor-proprietary. A sixth axis we check when it is published is the ingress and ambient temperature rating; a seventh is the materials and protective treatment (UL94 flame class, conformal coating, contact plating). Where the manufacturer does not publish a figure for a revision we are checking, we write that the axis is unverified rather than claim it is matched.

There are cases where the substitution discipline fails. A safety relay, an emergency-stop contactor, a motor protector in a category-one stop circuit, a sensor in a SIL-rated loop — these are not lines we substitute, even when the form, the electrical rating, and the protocol match on paper. The substitution is the wrong answer there because the certification chain that backs the original MPN does not transfer to the substitute without a documented re-qualification. For those lines, the only correct answer is the original MPN, or a documented equivalent from the same manufacturer, or a controlled migration to a newer-generation part from the same manufacturer.

We will not write equivalence claims on any quote line. We do not have the authority to make those claims, and a buyer's qualification cycle should not depend on them.

Why This Matters for Buyers in Russia, the CIS, and Other Long-Distance Destinations

A buyer in Moscow, in the Urals, in Siberia, in Kazakhstan, or in Belarus who receives a too-low quote faces an extra risk that a buyer in a neighbouring market does not: the part has to travel further, the shipping cost is non-trivial, the customs declaration has to be filed correctly, and the verification window is shorter. If the part turns out to be wrong, the entire round-trip cost is lost and the machine stays down. That is why the same verification sequence we apply on every quote line matters even more for long-distance destinations: the photo record, the condition in writing, the lot provenance, the bench-test record, the payment terms tied to a verifiable entity. We screen end users and end uses, classify before quoting, and decline transactions that cannot be screened.

Delivery to Russia and the CIS is arranged under DDP where the quotation states it; for shipments under EXW or DAP, the importer carries the import duties and the customs clearance. The freight forwarder, the commercial invoice, and the packing list accompany the shipment per the incoterms stated on the quote. Per-line conditions (new surplus, refurbished, or used) are stated on the quote, and the warranty terms are stated on the quote. Payment is by bank transfer against a proforma invoice on a registered entity, or by Payoneer where the buyer prefers it.
