This is why comparing quotations line by line on price alone is unreliable. A quotation is really a collection of commercial assumptions. The buyer needs to bring those assumptions onto the same basis before deciding which supplier is cheaper.
Consider a simple example. Supplier A quotes a drink at USD 18 per carton with 20 bottles inside. Supplier B quotes USD 20 per carton with 24 bottles. Supplier A has the lower carton price, but each bottle costs USD 0.90 before freight. Supplier B works out at about USD 0.83 per bottle. The supposedly more expensive quotation is already cheaper at the sellable-unit level.
Now suppose Supplier B also packs those 24 bottles into a carton that occupies only slightly more space than Supplier A’s 20-bottle carton. The difference becomes larger once freight is allocated. This is why the first step in quotation comparison should usually be to reduce every product to comparable units: cost per piece, cost per kilogram or another measure that reflects how the product will actually be purchased and sold.
Carton configuration matters more than many buyers expect. A catalogue may show two similar snacks at nearly identical prices, while one contains 12 consumer packs per carton and the other contains 30. The price of the carton tells very little until the contents are understood. Gross weight and carton dimensions matter as well because the product still has to be transported. A low-value carton occupying a large amount of CBM can be expensive to import even when its factory price looks attractive.
The same logic applies to MOQ. Supplier A may require ten cartons while Supplier B requires twenty, making Supplier A appear much more flexible. If Supplier A packs 60 retail units into every carton and Supplier B packs 20, their actual minimum commitments are 600 units and 400 units respectively. The buyer should calculate how many sellable units the MOQ represents, how much container space it takes and how long that quantity is expected to remain in inventory.
A professional comparison therefore does not ask only which supplier has the lower MOQ. It asks which minimum fits the expected sales.
Put every quotation on the same commercial basis
Price comparison becomes particularly unreliable when suppliers are quoting under different Incoterms.
One supplier may quote EXW from its factory, another FCA at an agreed Korean terminal or warehouse, and another FOB from a Korean port. Those prices cover different portions of the journey, so putting them next to each other without adjustment is not a fair comparison.
ICC’s Incoterms rules define the responsibilities, costs and risks assigned to buyer and seller under each term. Incoterms 2020 remains the current edition. ICC also states that FOB is intended for sea or inland-waterway transport where delivery takes place on board the vessel. Where containerised goods are handed to a carrier at a terminal before loading, ICC advises considering FCA instead.
For the buyer, this means a quotation should always include the named place as well as the Incoterm. “FCA Korea” is incomplete. “FCA supplier warehouse, Busan” and “FCA Busan container terminal” can create different costs.
Suppose Supplier A quotes USD 10,000 EXW and Supplier B quotes USD 10,400 FCA at the consolidation warehouse. Supplier A initially appears USD 400 cheaper. If collecting Supplier A’s goods from the factory costs USD 650, Supplier B is now cheaper before international freight even begins.
The buyer should therefore adjust both quotations to a common point in the supply chain. This can be the consolidation warehouse, Korean port, destination port or importer warehouse, depending on how the company prefers to compare costs. The exact point matters less than consistency.
The same principle applies to freight-inclusive quotations. A supplier offering CFR or CIF may appear convenient because international carriage is included, but the buyer still needs to know the routing, destination charges and what remains payable after arrival. An importer comparing a supplier-arranged freight rate with its own forwarder’s quotation should compare the total shipment cost, not merely the ocean-freight line.
Payment terms also belong in this comparison. A quotation requiring 100% payment before production is commercially different from one requiring a deposit and balance before shipment. Longer credit terms have value because the importer holds its cash for longer, although the value of those terms depends on the buyer’s financing costs and relationship with the supplier.
A slightly higher product price can therefore coexist with better overall commercial terms.
Shelf life can be worth more than a small price discount
Food quotations need another column that many ordinary procurement comparisons do not: remaining shelf life.
Suppose Supplier A quotes a snack at USD 21 per carton and Supplier B quotes USD 22. Supplier A is USD 1 cheaper, which saves USD 500 on a 500-carton order.
Then the buyer learns that Supplier A’s stock will ship with six months remaining, while Supplier B expects eleven months remaining.
The USD 500 saving now needs to be compared with the commercial value of another five months of shelf life.
If the product sells quickly, six months may be completely acceptable. If the importer needs six weeks for freight and clearance and retailers require several months remaining when they receive stock, Supplier A may leave very little selling flexibility.
The cheaper quotation can create pressure later through promotions, markdowns or rejected deliveries.
Remaining shelf life should therefore be requested at the same stage as price. For ready stock, buyers should ask what dates are available. For fresh production, they should understand the likely manufacturing and dispatch schedule. A vague statement that a product “has twelve months shelf life” is not enough if several months have already passed before shipment.
Certification and documentation should be treated in a similar way. If the importer requires a specific Halal certificate, HACCP documentation, product specification or certificate of origin, the comparison should record whether the supplier can actually provide what is needed. A lower quotation becomes irrelevant if the missing documentation prevents the importer from clearing, registering or selling the product as planned.
This does not mean that every supplier needs every certification. The requirements depend on the product, destination and customer. The buyer simply needs to compare suppliers against the requirements of the actual transaction.
Lead time is another commercial cost that rarely appears in the unit price.
Supplier A may quote USD 0.05 less per unit but require six weeks before the goods are ready. Supplier B may have stock available within one week. If the buyer is replenishing a fast-moving product and the slower supplier creates a month of stock-outs, the five-cent saving can become insignificant.
For a new product launch, the opposite may be true. The buyer may be willing to wait for fresh production because demand has not started yet and the additional shelf life is more useful than immediate availability.
Quotations should therefore be compared against what the importer is trying to achieve with that particular shipment.
The final comparison should use landed cost
Once the commercial details have been normalised, the buyer can estimate the landed cost of each option.
That calculation begins with the product cost under the agreed Incoterm and adds the expenses needed to bring the product to the importer’s chosen endpoint. Depending on the shipment, this can include Korean domestic transport, consolidation, origin charges, international freight, insurance, destination handling, customs duties, clearance and local delivery.
Customs valuation should be treated separately from the company’s internal landed-cost calculation. Under the WTO valuation system, customs value is primarily based on transaction value, meaning the price actually paid or payable for goods sold for export, with specified adjustments. National customs rules determine how this is applied in the importing country.
For procurement, however, the buyer usually wants to know what each product really costs when it enters inventory.
Imagine two quotations for the same category.
Supplier A offers 500 cartons at USD 20 each, giving a purchase value of USD 10,000. After allocating origin transport, freight, handling and other relevant import costs, those cartons land at USD 25 each.
Supplier B charges USD 21 per carton, so the purchase value is USD 10,500. Its cartons are smaller, however, and the shipment uses less freight capacity. It also has more favourable origin handling. The final landed cost comes to USD 24.20 per carton.
Supplier A won the factory-price comparison.
Supplier B won the actual import comparison.
The analysis should then go one step further and divide the landed carton cost by the number of consumer units. If Supplier B also has more pieces per carton, its advantage may become larger again.
This is the number that should eventually be compared against the expected wholesale or retail price.
A buyer should also be careful with mixed shipments because common freight costs need to be allocated reasonably. Dividing freight equally across every carton can distort the economics when the shipment contains both compact beverages and bulky snacks. Depending on how the freight is charged, allocation by CBM, gross weight, shipment value or a combination may give a more useful result.
The objective is not to produce a mathematically perfect allocation. It is to avoid making purchasing decisions using a cost method that obviously favours one type of product over another.
There is also value in keeping both the original quotation and the final landed-cost result. After the shipment arrives, the buyer can see where the estimate was wrong. Perhaps freight increased, the final volume was larger than expected or local handling charges were underestimated. Over several shipments, this history becomes useful during negotiations because the buyer knows which suppliers consistently produce better final economics rather than simply remembering who usually sends the lowest price list.
A good quotation comparison eventually becomes quite ordinary. The buyer looks at the product price, units per carton, carton dimensions, gross weight, MOQ, remaining shelf life, Incoterm, lead time, payment terms, required certificates and expected landed cost. None of those numbers is particularly complicated on its own. The difficulty comes from comparing them together.
That is why the cheapest line on the quotation is often the wrong place to finish the analysis.
For an importer, the useful question is not “Who quoted the lowest price?”
It is “Which quotation gives us the product at the best workable cost, in a quantity we can sell, with enough shelf life and the documents we need?”
