The answer first
Not yet. Two suppliers can both quote a “750 W submersible pump, FOB” and still be offering different saleable products. Before comparing unit prices, an importer should normalize the duty point, destination-market electrical version, included accessories, packing, evidence and delivery responsibilities. A price difference becomes meaningful only after those items are comparable.
The expensive part of a quotation is often what it leaves unsaid
Imagine a private-label importer planning an order of 1,000 pumps. Supplier A quotes US$22 per unit and Supplier B quotes US$25. These are invented figures used solely to explain the method—not YARDPUMP prices, market averages or a real supplier case. A appears US$3,000 cheaper on paper. But A has not stated cable length, destination-market plug, flow-test conditions or the accessory pack; B has documented each one. That does not prove B is better. It proves the buyer needs the same specification sheet completed by both suppliers before a valid comparison can begin.
Put both offers into one comparison sheet
| Decision item | Offer A (illustrative) | Offer B (illustrative) | Evidence to request |
|---|---|---|---|
| Application and duty point | Qmax/Hmax only | Q–H curve provided | Same flow at total head and permitted liquid |
| Electrical version | “750 W” only | Voltage, frequency, plug | Market-specific nameplate and cable specification |
| Components and protection | Unspecified | Options listed | Impeller, winding, seals, protections, revision |
| Accessories and pack | “Standard packing” | Pack list supplied | Adaptor, manual, retail box, carton, barcode |
| Quality evidence | “Factory inspected” | Record types listed | Agreed checks, sampling, traceable records |
| Commercial terms | “FOB” without port | Port and quantity stated | Incoterms version, named port, MOQ, lead time |
A more complete offer is not automatically a higher-performing pump. It is simply easier to verify. For hydraulic performance, never combine one headline maximum-flow figure with another maximum-head figure and treat them as one operating point. Ask for the flow available at the same total head and electrical supply, together with the curve or test-record revision.
Use gates before scores
First apply non-negotiable gates: the voltage and frequency must suit the target market; the intended liquid, particle size, temperature and submersion depth must fall within the selected model limits; the agreed duty point must be achievable; and any market-specific safety or compliance documentation must be verified. An unanswered gate should be marked “to be confirmed”, not hidden inside an arbitrary weighted score.
Next compare negotiable choices such as cable length, color, retail pack, label language, hose adaptor and spares. Finally compare MOQ, sampling and artwork charges, lead time, payment, warranty handling, inspection agreement and shipping responsibilities. A low unit price that omits required items is not a normalized price.
FOB is not delivered-to-warehouse cost
An FOB quote needs a named port and an agreed Incoterms version. Under FOB, delivery and risk transfer are tied to goods being loaded on the nominated vessel. Containerized, multimodal or air shipments may call for a different term, such as FCA, agreed with the buyer’s freight professional. Do not compare “FOB Ningbo” with a delivered warehouse price as though the two include the same obligations.
A buyer-ready clarification email
Please re-quote against one agreed target market and model revision. Confirm: (1) intended liquid and limits; (2) required flow at total head; (3) voltage, frequency, plug and cable length; (4) main component and protection choices; (5) included accessories, manuals and packaging; (6) available performance, safety or production-check records; and (7) MOQ, sample/customization charges, lead time and named-port FOB or another mutually agreed delivery term. Mark unresolved items TBC rather than “standard”.
When is the lower-priced offer actually the better buy?
Only after both offers pass the hard requirements, the accepted configuration is tied to a revision-controlled specification, the delivery and after-sales responsibilities are clear, and the buyer is satisfied with the supporting evidence. If a supplier cannot explain the duty point or electrical version, obtain the missing information before deciding.
