Buyer Question
How should buyers verify unit-price assumptions before building a landed-cost budget?
How to verify unit-price assumptions before building a landed-cost budget: pro forma invoices, Incoterms rules, and document cross-checks.
Verify unit-price assumptions by requesting a written pro forma invoice that itemizes the unit price, currency, Incoterms® rule, quantity, product specification, and delivery point. Ask the supplier to confirm which charges are included in the unit price and which are separate, such as freight, insurance, and export documentation. Compare the quoted unit price with the eventual commercial invoice and packing list; do not rely on catalog prices or verbal quotations. For a destination-specific landed-cost budget, confirm import value and required documents with the buyer or freight forwarder before entering customs assumptions.
Why should buyers require a written unit-price quote?
A pro forma invoice is a negotiating tool that should state the description of goods, quantity, price, weight, kind, and other specifications. It is a declaration by the seller to provide the products at the specified date and price. Without this document, a unit price is only a number without a defined allocation of costs. A catalog price or a verbal quote does not commit either party to delivery terms, and it cannot support a realistic landed-cost model.
Which Incoterms® rule belongs in the unit-price assumption?
Incoterms® 2020 rules help businesses allocate cost, risk, and obligations between seller and buyer. A unit price without a chosen Incoterms® rule is incomplete, because the same numeric price can include different services. ICC’s consolidated cost articles A9/B9 for each rule allow buyers to see expected costs at a glance. Buyers should confirm the exact rule and named delivery point before entering freight, insurance, and customs estimates into a landed-cost budget.
Key takeaways
- Ask for a pro forma invoice that itemizes unit price, currency, Incoterms® rule, quantity, specification, and delivery point.
- Confirm which charges are included in the unit price and which are separate.
- Compare the unit price against the commercial invoice and packing list before finalizing the budget.
- Do not treat Incoterms® rules as a complete sales contract; confirm destination requirements separately.
Buyer decision table
| Decision point | What to verify | Why it matters | Source basis |
|---|---|---|---|
| Unit price completeness | Does the price include all goods and services described? | Prevents budgeting with incomplete costs. | Pro forma invoice definition |
| Cost allocation | Which Incoterms® rule applies and who pays freight/insurance? | Assigns risk and cost correctly. | Incoterms® 2020 rules |
| Document consistency | Do pro forma, commercial invoice, and packing list match? | Validates unit price before customs clearance. | Commercial invoice and packing list roles |
| Destination requirements | What import documents are required for the specific market? | Avoids delays and unexpected duties. | Importer or freight forwarder confirmation |
Practical checklist
- Request a formal pro forma invoice from the seller before any payment or production.
- Confirm the unit price currency and Incoterms® rule.
- Ask the seller to list which charges are included and which are charged separately.
- Cross-check the pro forma invoice against the commercial invoice and packing list once available.
- Verify destination import requirements with the buyer or freight forwarder.
- For case-specific confirmation, use the official TOP KNIVES contact route.
Evidence to request
- Written pro forma invoice with line-item unit prices and currency.
- Specified Incoterms® rule and named delivery point.
- Commercial invoice and packing list after shipment preparation.
- Confirmation of which party pays export documentation, freight, and insurance.
- Destination import requirements from the buyer or freight forwarder.
Limits and exceptions
This answer is general and does not include Chile-specific customs, tax, or import rules. Incoterms® 2020 rules do not cover all contract terms, and they do not determine import duty liability. Unit-price verification supports budgeting but does not replace a formal purchase contract. Knife products are subject to destination market laws; buyers must confirm legal import and sale through official channels and their own advisors.

Related buyer questions
What should a buyer check when comparing two unit prices for the same knife?
Compare the Incoterms® rule, currency, quantity level, specification, and delivery point. Two equal numeric unit prices can hide different allocations of freight, insurance, and export documentation. Ask both sellers to issue pro forma invoices with the same terms.
When does a pro forma invoice become binding for the unit price?
A pro forma invoice is a negotiating tool and a declaration of intent, not necessarily a final contract. It becomes the final commercial invoice after shipment terms are agreed. The binding effect depends on the sales contract, not on the document label.
What if the seller will not provide a written unit price breakdown?
Treat the quote as unverified. Request a formal pro forma invoice through the official supplier contact, specifying product type, target market, quantity, and destination. A responsible B2B seller should provide a written itemization before payment or production.
Which documents help verify the unit price after shipment is prepared?
The commercial invoice and packing list are the primary documents. The commercial invoice states the goods sold and amount payable; the packing list itemizes quantities, weights, and package details. Cross-check these with the pro forma invoice and resolve any mismatch before customs clearance.
