Chinese supplier quotations are difficult to compare because the same unit price can refer to different product versions, quantity bases, packaging, testing, delivery scope and payment exposure. Normalise those assumptions before comparing MOQ, price or lead time. The framework below works across product categories; the Air Fryer example then shows how product-specific differences change the result.
What this page helps you decide
This page helps you decide whether quotations are comparable, which costs need adjustment, what questions remain open and whether an apparent price or lead-time advantage survives after the offers are placed on the same basis.
It does not select a supplier. It separates source values, buyer estimates and unresolved assumptions so the commercial decision is not based on a misleading unit-price column.
A quotation-normalisation framework for any product
Start with the same product requirement and quantity basis, then record each supplier’s answer without filling gaps from websites or assumptions.
| Comparison field | Supplier A | Supplier B | Supplier C |
|---|---|---|---|
| Specification version | |||
| Quantity basis | |||
| MOQ and MOQ basis | |||
| Unit price | |||
| Incoterm and named place | |||
| Packaging included | |||
| Tooling or setup | |||
| Testing and compliance | |||
| Sample cost | |||
| Production lead time and starting event | |||
| Quotation validity | |||
| Payment terms | |||
| Open questions | |||
| Estimated landed unit cost |
Keep one-time and recurring charges separate. Sample, tooling, setup, testing and packaging-development costs should remain visible even if the buyer allocates them across an expected order quantity for planning.
Product MOQ and packaging or component MOQ may also differ. Record whether a minimum applies to the total order, each SKU, colour, size, material, printed packaging component or production batch.
EXW, FOB and DDP quotations cannot be compared directly as if they cover the same seller obligations and logistics costs. Either request one common Incoterm and named place or add separately sourced adjustments while retaining every assumption.
An estimated landed unit cost can be expressed as:
quoted product cost + allocated recurring and one-time charges + buyer-estimated logistics, import and handling costs
Label every buyer estimate, currency and quantity basis. Do not present an estimate as a supplier quote or conceal uncertainty inside one final number.
Start with one comparison baseline
Do not begin by asking which supplier is cheapest.
Begin by defining the version against which all quotations will be assessed.
The baseline may include:
- product format;
- capacity basis;
- destination-market version;
- key materials;
- required accessories;
- packaging scope;
- documentation;
- quantity;
- Incoterm;
- named place or port;
- required timing.
This baseline may come from the original RFQ, an approved specification or a revised requirement prepared after the first supplier responses.
A well-structured RFQ makes the baseline easier to establish. The relevant fields are explained in What an Air Fryer RFQ Should Include and organised in the Air Fryer RFQ Checklist. Even so, the baseline may still need to be revised after the first supplier responses.
The important point is consistency. Each quotation is compared with the same baseline, not with whatever assumptions happen to appear in that supplier’s document.
Record comparability and follow-up separately
A quotation can be partly comparable and still require supplier clarification or document review. These are different questions and should not be combined in one status field.
Comparability status
| Status | Meaning |
|---|---|
| Comparable on the defined basis | Core product, market-version and commercial assumptions are aligned on the current comparison basis |
| Partly comparable | Most core assumptions align, but identified differences remain |
| Not yet comparable | Material differences prevent a meaningful price comparison |
A quotation marked “not yet comparable” is not necessarily an unsuitable offer. It means that the available information is not yet aligned well enough for the price to be interpreted.
Follow-up status
A separate field can show the next action:
| Follow-up status | Meaning |
|---|---|
| Supplier clarification required | The quotation does not state enough information |
| Document review required | A claim depends on a certificate, report or specification |
| Sample check required | The quoted feature needs physical or functional confirmation |
| Order-specific confirmation required | The point depends on the final project, contract or production arrangement |
A quotation may carry more than one follow-up status.
Separate product differences from price differences
A different product should not be treated as a cheaper version of the same product.
Before comparing unit prices, confirm that each offer aligns on the main product definition:
- exact model;
- product format;
- capacity basis;
- market version;
- key materials;
- control configuration;
- included accessories.
At quotation stage, the immediate task is to determine whether each supplier is pricing the same product requirement.
Where the product differs, record that difference before interpreting the price.
Examples include:
- dual basket instead of divided chamber;
- advertised capacity based on combined zones;
- a different coating system;
- mechanical control instead of digital control;
- a standard accessory omitted;
- an alternative market version.
Only after the difference is visible can the price gap be understood correctly.
Confirm the entities behind each offer
The company name shown at the top of a quotation may not perform every role in the proposed transaction.
Record separately:
- legal entity issuing the quotation;
- proposed contracting entity;
- proposed payment recipient;
- manufacturing site;
- sales or export entity, where different.
These roles may belong to the same company, but that relationship should be confirmed rather than inferred from a website name, logo or email domain.
This becomes especially important where the quotation, certificate and proposed manufacturing site refer to different entities.
Multiple entities are not automatically a problem. The issue is whether their roles are understood before the order proceeds.
Separate unit costs from project costs
A quoted unit price often excludes costs that appear elsewhere in the project.
Project-level costs may include:
- tooling;
- mould changes;
- samples;
- artwork setup;
- panel development;
- software changes;
- testing;
- certification;
- packaging development.
Unit-level costs may include:
- the product;
- standard accessories;
- custom packaging;
- printing;
- labels;
- spare-parts allowance.
Keep these categories separate.
A one-time fee can be allocated across an estimated volume for internal planning, but the original charge should remain visible. Otherwise, a supplier with a lower unit price and a higher development cost may appear cheaper than it is.
Align quoted quantity, MOQ and configuration
MOQ is rarely meaningful without its scope.
A stated minimum may apply by:
- model;
- colour;
- plug;
- packaging version;
- control panel;
- accessory;
- production batch.
For example, a supplier may accept 1,000 units in total but require 1,000 units per colour. Another may allow mixed colours but apply a different unit price.
The comparison should therefore record:
- quoted quantity;
- MOQ basis;
- permitted mix;
- price breaks;
- trial-order terms;
- separate minimums for customised items.
Until those conditions are visible, two MOQ figures may not describe the same commercial flexibility.
Align the Incoterm and named place
Record the Incoterm and named place or port exactly as quoted.
EXW, FOB, CIF and DDP do not represent the same seller obligations or cost scope. Their unit prices should not be placed in one comparison column without adjustment or explanation.
Even the same Incoterm can cover different logistics assumptions when the named place differs.
A quotation labelled only “FOB China,” for example, does not identify the named port required for a precise comparison.
Where the offers use different trade terms, either:
- request revised quotations on one basis; or
- retain the original terms and show the adjustment separately.
Do not hide the difference inside a single landed-cost figure without retaining the source assumptions.
Align the timing assumptions
A shorter quoted lead time does not automatically mean a faster project.
Compare:
- sample type;
- sample lead-time starting point;
- production lead-time starting point;
- packaging approval assumptions;
- material availability;
- pre-production sample requirements;
- shipment-ready definition.
One supplier may count from deposit, while another counts from final artwork approval. A third may exclude the time required for custom materials.
The schedules become comparable only after their starting events and included stages are aligned.
Keep documents and open points connected to the quotation
A supplier may refer to certificates, reports or specifications that are not attached to the quotation.
Record:
- what document was provided;
- what model or model family it covers;
- what entity, manufacturer or factory it identifies, where stated;
- whether the destination-market version appears to match;
- whether further review is required.
Missing information should remain visible.
Useful evidence-record statuses include:
- confirmed in quotation;
- supported by document;
- different record found;
- not stated.
“Different record found” means that another source shows a different value, entity, model reference, date or scope. It does not by itself establish which record is correct.
Any required supplier clarification, document review, sample check or order-specific confirmation should remain in the separate follow-up field.
The record should also identify the source of the information, such as a supplier document, company website, registry record, public filing or commercial platform.
Do not complete a missing quotation field with a website statement, marketplace listing or another model’s specification.
Those sources may help formulate the next question. They do not become the supplier’s model-specific answer.
Illustrative Air Fryer comparison
The figures below are a hypothetical example created only to show the normalisation method. They are not market prices, supplier offers or sourcing benchmarks.
| Field | Supplier A | Supplier B | Supplier C |
|---|---|---|---|
| Quoted version | 5 L digital, standard coating, V2 RFQ | 5 L digital, alternative basket coating, V1 RFQ | 5 L digital, standard coating, V2 RFQ |
| Quantity basis | 1,000 units, one colour | 1,000 units, two colours | 800 units, one colour |
| Illustrative unit price | USD 31.80 FOB Ningbo | USD 30.90 EXW | USD 35.40 DDP to named warehouse |
| MOQ basis | 1,000 per colour | 500 per colour; printed box minimum separate | 800 total; one colour |
| Packaging | Custom colour box included | Stock box included; custom box extra | Custom colour box included |
| Testing and setup | Existing report offered for review; model coverage open | Testing excluded; artwork setup USD 180 | Testing responsibility not stated |
| Production lead time | 35 days from deposit and artwork approval | 30 days from deposit; custom-box timing open | 42 days from deposit and final sample approval |
| Payment terms | 30% deposit, balance before shipment | 40% deposit, balance before shipment | 30% deposit, balance before dispatch |
| Comparability | Baseline offer | Not yet comparable: version, trade term and packaging differ | Partly comparable: delivery scope and quantity differ |
Supplier B’s lower unit price does not show that it is the lower-cost offer. The quoted product version, EXW scope, packaging exclusion, setup charge and open testing position must first be aligned. Supplier C includes a broader delivery scope but uses another quantity and lead-time basis. The same method applies to products other than air fryers; only the product-specific fields change.
A workable comparison sequence
A practical sequence is:
- define the comparison baseline;
- confirm the quoted entities;
- assign a comparability status;
- record product differences;
- separate unit and project costs;
- align quoted quantity and MOQ assumptions;
- align trade terms and named delivery points;
- align lead-time starting points;
- connect documents to the quoted model;
- record the required follow-up actions.
At that point, the unit-price comparison becomes meaningful.
When the quotations are ready to compare
A structured comparison does not determine which supplier should receive the order.
It does show:
- whether the offers describe the same product;
- why the prices differ;
- what costs are included;
- what assumptions remain open;
- what needs clarification before the commercial decision.
Quotation normalisation does not remove the need for judgment. It makes sure that the judgment is based on comparable information.
Once a sample is selected, the same model, market-version and component references should carry forward into the controls described in Why an Approved Air Fryer Sample Does Not Guarantee Consistent Mass Production.
The Air Fryer Quote Comparison Template records each offer against the same fields and keeps material differences visible. Quotations that remain materially different should stay marked as partly comparable or not yet comparable until the open points are resolved.
Common mistakes and pause conditions
- Do not rank prices before confirming the specification version and quantity basis.
- Do not treat MOQ as one number when product, colour, component or packaging minimums differ.
- Do not compare lead times without recording whether the clock starts at deposit, artwork approval, material approval or final sample approval.
- Do not move to sample or production approval while a material product difference, cost exclusion, entity conflict or required document remains unresolved.
