Before you negotiate the unit price, build a landed-cost floor. If the full cost per sellable unit is unclear, the margin is still a guess.
The quick landed-cost formula
Use this rough structure before paying for a sample, deposit, or first production order:
| Cost bucket | What to include | What to ask before paying |
|---|---|---|
| Product cost | Unit price, MOQ, sample fee, mold fee, packaging cost, customization cost. | Does the PI match the chat quote and Alibaba order draft? |
| Freight | Courier, air, sea LCL, FCL, fuel surcharge, documentation, pickup, delivery. | What Incoterm, carton data, route, and quote validity are being used? |
| Import costs | Duty, taxes, customs entry, broker, tariff layers, exams, storage, demurrage risk. | Which costs are included, excluded, or only estimates? |
| Operational loss | Defects, replacements, inspection, payment fees, exchange-rate buffer, unusable inventory. | How many units must be sellable for the order to still work? |
A simple first pass is: Total landed cost per sellable unit = all product, freight, import, and operational costs divided by the number of sellable units.
What usually gets missed in first Alibaba orders
- Freight quote validity and fuel or peak-season surcharges.
- Carton dimensions, gross weight, chargeable weight, and CBM.
- Whether a DDP quote truly includes duties, taxes, customs clearance, and final delivery.
- Destination charges that appear after goods arrive at the port, airport, or warehouse.
- Bank wire fees, currency conversion, platform fees, and receiving-bank deductions.
- Defect allowance, replacement units, inspection cost, and packaging that changes after sampling.
Supplier questions to copy before payment
- Can you update the PI or Alibaba order so product price, freight, Incoterm, quantity, and payment terms all match?
- What are the carton dimensions, gross weight, number of cartons, and total CBM?
- What freight method is quoted, and how long is the freight price valid?
- Which charges are included and excluded after the goods leave your factory?
- If this is DDP or door-to-door, does it include customs clearance, duties, taxes, and final delivery to my address?
- What cost changes would trigger a revised quote after I pay the deposit?
When a quote is not ready to pay
Pause before payment if the supplier cannot put the shipping term, carton data, included charges, lead time, and payment terms into the PI or Alibaba order. Chat promises help, but the payable order record is what you will rely on if the price changes later.
