How to Compare Cable Supplier Quotations: A Checklist for Central Asian Buyers
Quick Answer: Two cable quotations can only be compared if they describe the same product, the same delivery and the same assumptions. Work down the comparison line by line: specification consistency against your enquiry, conductor and structure, the standard and tests behind each line, drum lengths, packaging, trade terms and validity, technical deviations, and what each offer leaves out. Then total the procurement cost to the named destination rather than the unit price. The blank comparison sheet at the end of this guide is built for that pass.
Introduction
Comparing cable offers is where a good RFQ pays off, and where a loose one gets exposed. Offers written against the same structured enquiry differ in ways you can weigh; offers written against a loose enquiry differ in ways you cannot, because each supplier filled the gaps differently. Either way, the comparison method is the same: a fixed checklist, worked line by line, with the differences recorded where you can see them.
This guide is for buyers in Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan and Turkmenistan holding two or more cable quotations from Chinese factories. It works through the nine comparison axes, explains what each one hides when it is skipped, and ends with a blank A/B comparison sheet ready to copy. The quotation itself is the output of the RFQ process described in this series; here we assume the offers are on the desk.
Check Specification Consistency Against Your Enquiry
Read each offer against your list, not against the other offer. The first pass confirms that every line of your enquiry has been answered: same construction, same standard, same quantity basis. A line answered with a “similar” construction is a deviation and belongs on the deviation list, not silently inside the comparison.
Watch for merged and dropped lines. Offers occasionally combine two of your lines into one item or quietly drop the line a factory prefers not to build. Both make the total look different without any unit price moving. Reconcile the line count before comparing anything else, because a missing line is a bigger difference than any discount.
Confirm the quantity basis. Total metres per line, with the drum splits to be fixed, is the basis your enquiry set. An offer that reprices your quantities in factory-standard rounds has changed the purchase, and the change belongs in the open, priced, not buried in a tidy number.
Compare Conductor and Structure
Conductor material and class decide most of the price. Copper against aluminium, stranded against compacted, flexible against fixed, are different cables with different prices, and the difference is legitimate only when both offers priced what you asked for. Where one offer is visibly cheaper, the conductor column is the first place the saving hides. The cost structure behind this is covered further in our note on XLPE cable construction.
Insulation, screen, armour and sheath, line by line. The compounds, the screen structure, the armour type and the sheath material are where equivalent-looking offers diverge. A PE sheath quoted against a PVC specification, a steel tape armour against a wire armour request, an unshielded control construction against a screened one: each is a real difference in performance and in price, and each belongs on the comparison sheet as its own row.
Where structures differ, ask for the reason before the price. A supplier who proposes a different structure with a reason and evidence is offering information; a supplier who quietly substitutes has offered a discrepancy. The comparison sheet carries both the same way: what you asked, what is offered, the difference.
Compare the Standard and the Tests
The standard per line is the comparison’s anchor. Offers quoting the same construction against different standards are not describing the same cable, and the tender that enforces one standard will not accept the other on faith. Confirm that the standard named in each offer matches your enquiry, and where an equivalence is claimed, check that evidence accompanies it rather than adjectives.
Routine batch tests and type reports are part of the price. One offer may include batch test reports tied to drum numbers and current type reports per construction; another may include neither and look cheaper. Ask what is included, and price the missing documents at what they will cost you to obtain later, because that is their real price in the comparison.
Special tests belong in the sheet too. Witness testing, additional reports, buyer-specific certificates: quotable items with lead times, and different suppliers will have drawn different lines around them. The offer that states its boundary is easier to compare than the one that has not thought about it.
Compare Lengths and Packaging
Drum lengths change the delivered product. The same quantity in long drums and in short drums is not the same delivery: the jointing, the handling and the installation time all follow the split. Compare the available lengths offered per line, and where one supplier’s drums fit your installation plan better, that difference is worth real money the unit price does not show. The jointing consequences are set out in our note on drum length and jointing strategy.
Packaging for the real route, specified identically. Offers quoted against the same packaging specification compare like with like; offers quoted against each factory’s default compare habits. Drum type, flange protection, cable-end sealing and packing for the transport mode belong in the comparison, and the export practice behind them is set out in our note on export drum packaging.
Marking and identity are comparison rows as well. Drum numbering, label content, batch references and the packing list format decide whether the shipment can be checked at the border and the site. An offer that confirms them is carrying a service the cheaper-looking offer may not include.
Compare Trade Terms, Destination and Validity
The delivery basis must name the same place. Offers delivered “to Almaty warehouse”, “to the border” and “FOB Chinese port” are three different purchases. Convert them to the same footing, your named destination with the risk transfer point, before any price comparison means anything.
The copper basis and validity window decide whether the price still exists. One offer on a fixed basis valid thirty days, another on a moving basis valid fifteen: the comparison has to account for what each price will be when you actually order. Neither is wrong, but they are different instruments, and the sheet should record the basis and the window as rows of their own.
Payment terms and currency are comparison terms. Stage payments, documents against payment, currency of invoice: differences here change the real cost and the risk profile of the purchase. For repeat buyers they also set the template for every order that follows, so they are worth normalising across offers rather than accepting per supplier.
Put the Deviations on the Sheet
Every deviation is a comparison row with three columns. What you specified, what the supplier proposes, and the reason with its evidence. A deviation accepted for a good reason can make an offer better, not worse; a deviation discovered after the award makes the award worse. The discipline of collecting them before the decision is what the comparison sheet is for.
Weight deviations by the service condition they touch. A sheath change on a line with stated oil contact is a technical event; a colour change on an indoor line is a commercial one. The sheet lets you refuse the first and accept the second without a meeting, and the insulation-level trade-offs behind common deviations are covered in our note on XLPE compared with PVC insulation.
An offer without deviations is not automatically complete. Where your list needed deviation answers and none came, the missing sheet is itself a finding. Silence about differences is harder to manage than differences stated plainly, and the offer that states them is the easier one to hold to after the order.
Price the Omissions Before the Offer
What an offer leaves out is a cost you will pay later. Missing batch reports, unnamed drum lengths, an open destination, a silent packaging default: each omission becomes either a negotiation, an extra invoice or a problem at receipt. The comparison’s last technical pass is simply asking, line by line, what this offer does not say.
Add the missing items at their real cost. A document set you must obtain separately, freight you must arrange yourself, packing you must upgrade: price them into the comparison rather than letting the thinner offer win on the number that shows. This is arithmetic, not negotiation, and it is the step most comparison exercises skip.
Omissions also carry risk, not just cost. A delivery without agreed marking or a claim route is not just missing a service; it carries the probability of a dispute with no procedure. Weighting that properly is a judgement, and the sheet’s notes column is where it lives.
Total the Procurement Cost, Not the Unit Price
The real comparison is the landed, documented, installed-ready cost. Unit price per metre is one input. The total includes packaging, documents, freight to the named destination, the risk held inside the trade terms, and the site-side consequences of drum lengths and marking. Two offers rarely stay in the same order once this total is built, which is exactly why the total is worth building.
Record the assumptions beside the total. The exchange rate day, the freight quote date, the copper basis date. A comparison is a snapshot, and the sheet that says what day it was taken survives review; the one that does not invites a second argument about the arithmetic.
Use the total to decide, and the rows to negotiate. The line-by-line comparison shows where each offer is strong and weak, which is the agenda for the final round with the preferred supplier. Negotiating the rows is how a good offer becomes the right order; negotiating only the total is how a wrong order gets a discount.
Blank Quotation Comparison Sheet
The sheet below is a copyable A/B template. Fill one sheet per pair of offers, or add columns for more. The cells are deliberately blank; the sheet compares your offers, not any market price. The “What Decides It” column names the test each row has to pass.
| Comparison Item | Quotation A | Quotation B | What Decides It |
|---|---|---|---|
| Line coverage | Every line of the enquiry answered; nothing merged or dropped | ||
| Specification consistency | Construction matches the enquiry line, or is listed as a deviation | ||
| Conductor material and class | Exactly the material and class requested, on every line | ||
| Structure (insulation, screen, armour, sheath) | Structure matches; differences recorded with reasons | ||
| Standard per line | The standard the project enforces, with evidence for any equivalence | ||
| Tests and documents included | Routine batch reports tied to drum numbers; type reports current | ||
| Drum lengths offered | Lengths that fit the installation and jointing plan | ||
| Packaging and marking | Same specification across offers; identity survives the route | ||
| Delivery basis and destination | Same named destination and risk transfer point in both | ||
| Copper basis and validity window | Basis and window that survive the real decision date | ||
| Payment terms and currency | Terms comparable, or converted to a common footing | ||
| Deviations proposed | Each with a reason and evidence, weighted by the condition affected | ||
| Items omitted | None silent; each omission priced at its real cost | ||
| Total procurement cost to destination | Price plus packaging, documents, freight and risk, on one date |
| Omission | Where It Shows Up | How to Price It |
|---|---|---|
| Batch test reports not mentioned | Receipt, when the inspector asks for them | The supplier's charge for producing them, or the inspection cost of proceeding without them |
| Type report scope unstated | Handover, when the document controller checks the line list | A retest quote, with its lead time added to the programme |
| Packaging left to factory default | Unloading, on drums damaged by the route | The upgrade to the specified packing, quoted as a line item |
| Marking content unspecified | The border and the site, on drums that cannot be identified | The delay and dispute cost of unmarked goods, or the re-marking charge |
| Freight to destination not included | The invoice, when the forwarder's quote arrives | Your forwarder's quote to the same destination, on the same date |
| Validity window missing | The order date, when the price has moved | The re-quote risk, weighted by the copper movement in your decision period |
| Claim route not addressed | The first nonconformance, when no procedure exists | The negotiation cost of a dispute with no rulebook, weighted honestly |
Cost and Lead Time in the Comparison
The comparison fixes the price you will live with. Once the award is made, the terms on the winning offer become the order’s terms, so the comparison is the last cheap moment to find a missing document set or an open destination. The arithmetic of omissions is what turns two unit prices into one real decision.
Lead time belongs in the sheet, not in a footnote. Production time per line, transit time to the named destination, and what happens if either moves: rows like any other. On a fixed programme calendar, a slower offer that includes the documents may beat a faster one that does not, and the sheet is where that trade becomes visible instead of remembered.
Compare the second order as well as the first. Where repeat supply is likely, the supplier’s stated MOQ, basis mechanism and document habit are the terms you will renegotiate nothing about. The offer that is built for repetition is worth a margin over the offer priced for a single win, and the buying sequence behind that is covered further in our note on buying cable from China.
Multi-specification repeat orders have their own mechanics, set out in our guide to wholesale cable orders from China.
When a Line-by-Line Comparison Is Not the Answer
When the offers were not written against the same enquiry. If the requests went out loose, the offers differ in kind, not in price, and no sheet fixes that. Re-issue the enquiry with the required fields, then compare. The structure it needs is set out in this series’ RFQ guide.
When one offer is disqualified on the technicals. An offer that cannot name its standard or refuses its document set is not a cheaper option; it is a different risk. Record the disqualification and compare the remainder, rather than carrying a number that will not survive the order.
When the purchase is a single small order. For a replacement drum or a small lot, compare the construction, the price basis and the delivery point, and stop. The full sheet earns its keep on purchases where the differences compound.
When the decision has already been made. A comparison run to confirm a choice already taken wastes the sheet and misleads the file. Run it honestly or note that the award rests on other grounds; the record should say which.

Conclusion
Comparing cable quotations is a reading exercise with a fixed checklist. The offers that survive it are the ones that described the same product, the same delivery and the same assumptions as your enquiry, and the comparison is what proves it. The blank sheet above turns that proof into a record, and the record is what makes the award defensible months later when someone asks why the second-cheapest offer won.
