China Sourcing Insights
A cheap unit price can become an expensive delivered product. Calculate like-for-like total costs before choosing a China supplier.
Quick answer: Do not compare two China supplier quotations by unit price alone. First make the product specification, order quantity, delivery point and Incoterm comparable. Then add the order-specific costs for samples, packaging, quality checks, China-side logistics, international freight, insurance, duties, taxes, customs clearance and destination delivery. Keep unknown items marked pending, not zero.
The U.S. Department of Commerce explains landed cost as the total cost once a product reaches the buyer, including the product price, freight, insurance, tariffs, taxes and other fees. The details depend on your destination, product and agreement; this page is a budgeting method, not a current tariff or customs quotation.
1. Why a low supplier quote can mislead
A supplier might quote $3.90 per unit but exclude packaging, origin trucking and export handling. Another may quote $4.10 per unit and include some of those costs. Neither price is meaningful for supplier selection until you specify the same order requirements and allocate all costs on the same basis.
Before calculating, lock five inputs: same SKU/specification, same quantity, same packaging, same destination and same required delivery window. Quality and lead-time differences also matter; a cost table does not replace product evaluation.
2. Build a cost list with a responsible owner for each number
| Cost category | Question to ask | Typical source |
|---|---|---|
| Unit purchase price | Exactly which spec, order quantity and currency apply? | Written supplier quotation |
| Samples, tooling and setup | One-time or per-order? Creditable or not? | Supplier / product developer |
| Packaging and labeling | Retail box, master carton, barcode, inserts included? | Supplier / packaging brief |
| Inspection and testing | Which check is needed, and who pays? | Inspector or qualified lab |
| China-side logistics | Factory pickup, inland trucking, consolidation, export handling included? | Supplier / freight forwarder |
| International freight and insurance | Air/sea/rail? Weight or volume basis? What is covered? | Freight forwarder / insurer |
| Duties, taxes and customs | Current HS classification, customs value, origin, permits or trade measures? | Destination customs / licensed broker |
| Destination charges | Terminal, brokerage, storage, final delivery, appointment or unloading? | Forwarder / broker / warehouse |
| Banking and FX | Transfer charges or exchange-rate spread? | Bank / payment provider |
For every estimate, record the source, quote date, currency, validity and whether tax is included. If a category is already part of the supplier’s quoted delivery term, do not count it again.
3. Read EXW, FOB and DDP as responsibility rules—not price-quality labels
EXW (Ex Works) generally places a substantial part of pickup, export and onward transport responsibility on the buyer. Depending on the jurisdiction and arrangement, this can be operationally difficult for an overseas importer. FOB (Free on Board) is a sea/inland-waterway rule tied to delivery of goods on board the named vessel. DDP (Delivered Duty Paid) generally assigns extensive import-clearance and duty obligations to the seller. Do not assume that an advertised “DDP shipping” offer correctly addresses who can act as importer in your destination or includes every possible local charge.
The applicable rules depend on the exact Incoterms 2020 rule and named place written in the contract. Ask your forwarder or customs specialist to confirm the practical allocation. Incoterms allocate delivery, costs and risk between parties; they do not settle product quality or transfer of ownership.
Use the ICC’s official rules for EXW and DDP and its FOB rules rather than treating a vendor’s one-line definition as the full contract.
4. Worked example: the cheaper unit price loses
Hypothetical training example: two suppliers quote the same 1,000-unit product and identical required specification. The numbers below are invented solely to show the arithmetic, in USD; they are not current quotes, tax rates or freight prices. Both quotes are normalised to the same buyer delivery point, with separate charges included where necessary.
| Cost for 1,000 units | Supplier A | Supplier B |
|---|---|---|
| Product (unit × quantity) | $4.10 × 1,000 = $4,100 | $3.90 × 1,000 = $3,900 |
| Packaging / labelling | $160 | $340 |
| China origin handling | $260 | $390 |
| International freight | $800 | $950 |
| Cargo insurance | $60 | $70 |
| Illustrative import duty / tax allowance | $580 | $580 |
| Broker / clearance charges | $170 | $170 |
| Destination delivery | $220 | $220 |
| Inspection budget | $190 | $190 |
| Bank / FX fees | $40 | $60 |
| Total illustrative landed budget | $6,580 | $6,870 |
| Budget per unit | $6.58 | $6.87 |
Supplier B appears $0.20 cheaper per unit at the product level, yet its illustrative all-in budget is $290 higher. The lesson is not that Supplier A is automatically better; the buyer must still compare quality, reliability, lead time and contractual responsibilities. Real duty and tax calculations may differ substantially because customs valuation and product classification depend on the destination and circumstances.
5. Calculate customs charges without inventing a tariff
Determine the importing country’s current HS classification and applicable measures for the specific item and origin. Ask a qualified broker or customs authority how the customs value is established and whether insurance, freight or other additions affect it. Then calculate the applicable duty and taxes using that jurisdiction’s current rules.
Do not transfer a rate found for one country, HS code or date into another shipment. A six-digit HS heading is not always enough to decide a destination’s full classification, and additional measures can apply. The U.S. Department of Commerce’s landed-cost guidance explains the components but does not replace destination-specific verification.
6. A useful quote-normalisation worksheet
Copy these columns into a sheet before choosing a supplier:
| Column | What to record |
|---|---|
| Identity | Supplier legal name, product SKU, specification revision, quantity |
| Commercial offer | Currency, unit price, MOQ, tooling, sample terms, lead time, quote validity |
| Delivery allocation | Incoterm version + exact named place; included and excluded services |
| Quality scope | Sample reference, inspection plan, testing responsibilities |
| Transport | Package dimensions/weight, shipping method, freight, insurance, destination |
| Import estimates | HS classification assumption, duty/tax source and date, broker |
| Result | Total cost, unit landed budget, unresolved assumptions and next action |
Use three statuses for each row: confirmed (written quote or verifiable rate), estimate (clearly sourced assumption) or pending (not yet known). If freight or tax uncertainty could change the supplier decision, do not replace “pending” with an optimistic zero.
7. Send this clarification request before comparing prices
Hello, we are comparing quotations for the attached specification and quantity. Please confirm your quoted product price and currency, MOQ, tooling and sample charges, packaging specification, production lead time, payment schedule, and the exact Incoterms 2020 rule with named place. Please itemize what is included or excluded for domestic transport, export handling, inspection, consolidation and shipping. Also confirm whether your price is valid for our delivery deadline and whether any additional fees are expected. Thank you.
Frequently asked questions
Can a DDP quote be treated as fully delivered, all taxes paid?
Only after the specific contract and destination import arrangements have been checked. Confirm who can perform import clearance and which charges remain excluded. The name “DDP” on a message alone is not enough.
Should sample fees and tooling be counted per unit?
For planning, you can spread applicable one-time costs across the units in the relevant order. For future repeat orders, keep separate views so you do not incorrectly charge the same one-time item again.
Is landed cost the same as retail profitability?
No. Retail platform fees, advertising, fulfilment, storage, returns, warranties and other selling costs may come afterward. Landed cost is one part of the margin calculation.
Can Sourzio quote customs duties for my destination?
Sourzio can help organize comparable supplier and logistics inputs within an agreed sourcing project. Official customs classification, tax treatment and import compliance must be confirmed with the relevant authorities or qualified specialists.
If you are evaluating several suppliers, Sourzio can help coordinate supplier information and quotation comparisons within an agreed scope. For an unfamiliar supplier, pair the commercial comparison with supplier background research.
