What to check beyond the factory price when sourcing for the U.S.

Short answer: Compare quotes on an equivalent product, the same delivery responsibilities, a reviewed import basis, and a realistic repeat-supply plan. The factory price is one input to that decision—not the finished cost of putting a dependable product in front of your customer.

First, make the products comparable.

Two suppliers can quote the same nominal item while offering different materials, performance, packaging, quality checks, or minimum order quantities. If those differences matter to your customer, the lower price is not necessarily the lower-cost program.

Give each supplier the same application and commercial brief. Specify the current product or sample if one exists, the performance that must be maintained, the proposed packaging, expected order volumes, and any documentation or testing requirements. Record which points are confirmed and which are still assumptions. An untested “equivalent” belongs in a validation plan, not in a price comparison as though it were already interchangeable.

Find the boundary of each quote.

Ask for the delivery term, its named place, and the version being used. Incoterms® clarify the tasks, costs, and risks allocated between seller and buyer, including transport and customs responsibilities. They do not, by themselves, describe every condition of the sale or make two quoted prices directly comparable.

For each offer, write down who arranges and pays for origin transport, international freight, insurance, import clearance, duties and fees, and delivery to your receiving point. Also ask who will handle an exception—a missing document, a delayed shipment, or damaged goods. The answer may change which internal team carries the work, even when the quoted unit price looks attractive.

Separate import treatment from your landed-cost estimate.

U.S. import treatment depends on the actual product and transaction. The importer of record is responsible for using reasonable care when entering, classifying, and valuing goods; a broker can help, but the importer should not treat a supplier’s suggested tariff code as final. CBP explains that the importer remains responsible even when using a broker.

Confirm the product description, classification, country of origin, customs value, and any additional measures with the importer’s customs professional. The U.S. International Trade Commission maintains the Harmonized Tariff Schedule, but a rate copied from a similar product or an old quote is not a dependable assumption. Tariff rules can change; recheck the relevant treatment before committing and again when the goods are entered.

Customs value and your commercial landed-cost estimate are related but not identical. Your estimate may include freight, brokerage, inland delivery, and other program costs; the customs valuation rules must be assessed separately for the transaction. CBP’s commercial-invoice guidance illustrates why the declared value should not be improvised from a resale price or a rough all-in estimate.

Build one side-by-side cost path.

Use the same destination and order quantity for every option. Add only costs your business will actually bear, and mark anything still estimated. Do not double-count a service already included in a supplier’s term. A useful comparison has five rows:

1. Product and program: unit price, packaging, testing, inspection, and any setup or tooling.
2. Origin: local movement, export handling, and documents not included in the quote.
3. International movement: freight, insurance if applicable, and foreseeable handling.
4. U.S. entry: broker charges, duties, fees, and any product-specific import requirements confirmed by the appropriate professional.
5. Final delivery: inland movement, receiving, and the working capital tied to the chosen order and lead-time pattern.

This is a decision model, not a promise that every project has the same cost components. The point is to expose the assumptions that make one offer look cheaper than another.

Then test the second and third shipment.

A first order can prove that a supplier can make and ship something once. It does not establish how changes, replenishment, or quality exceptions will be managed. Before choosing a source, agree on the approved specification, change-notification process, inspection points, lead-time assumptions, and who owns communication when production or delivery moves off plan.

Ask what would happen if demand rises, a component changes, or a shipment is rejected. You do not need a perfect forecast, but you do need to know which assumptions would break the program and who will make the next decision.

If the comparison involves replacing an established source, use the replacement-supplier evaluation guide to protect what already works for your customers.
