A lower supplier quote is not the cheaper option when it excludes applicable landed-cost items or compares unlike specifications and testing requirements. The relevant comparison is the total landed cost for equivalent goods, expressed as a cost per unit—not the quoted amount or shelf price alone.
The unit-economics answer
The International Trade Administration includes freight, insurance, tariffs and taxes, and other fees in landed cost. If an applicable item is left out of the comparison, a lower quote can lose its apparent advantage. Not every item necessarily applies to every order, so the buyer needs the transaction-specific treatment before treating a supplier quote as the total cost.
Penn State Extension recommends comparing food costs by their cost per unit rather than their retail price. In a supplier purchase, the corresponding discipline is to compare the same specified goods on the same quantity basis, rather than relying on a low headline price or the order total.
How to check the quotations
- Set the same basis. State the product specifications and any testing requirements in the request. The American Society for Quality says supplier quotations can be requested against stated specifications and other requirements, such as testing. Quotations based on different requirements are not automatically comparable.
- Use a common unit basis. Identify the quantity, unit, and exact product specification for each quotation, then compare cost per unit.
- Account for landed cost. Record whether freight, insurance, tariffs, taxes, and other fees are included, separately stated, or still unresolved. The buyer must establish which items apply and what they cost for the specific purchase.
- Keep gaps visible. A fee that is not included, not stated, or not confirmed should remain an open item rather than being silently omitted.
What still needs confirmation
The cited guidance does not establish a minimum order quantity, fee amount, payment term, delivery deadline, refund policy, or contractual right for a particular food purchase. Those details must be checked in the actual written quotation and agreement rather than inferred from a general landed-cost explanation.
Before approval, the buyer should confirm:
- the exact product, quantity, and any testing requirement;
- whether each relevant freight, insurance, tariff, tax, and other fee is included, separately listed, or unresolved;
- any conditions, exclusions, or additional charges that affect the total; and
- the applicable payment and delivery obligations.
A lower quote becomes meaningful as a lower-cost option when it remains lower on a comparable unit basis and all applicable landed-cost items are visible. Before that, the lower number is an incomplete signal, not proof of a lower total cost.
