Every sourcing conversation starts with the same question: what is the FOB price? It is an easy number to compare, it fits in a spreadsheet, and it feels like the decision. It is also the number that explains the least about what a product will really cost you over its life.

A quotation is a snapshot of one supplier’s assumptions on one day: a specific material grade, a specific tolerance reading, a specific batch size, a specific idea of what "good" means. Two quotations that differ by twelve percent are usually not pricing the same product at all.

FOB is a snapshot, not a cost structure

A price becomes reliable only when you can see what is inside it. When we break a quotation down with a supplier, the conversation moves from negotiation to engineering: which operations drive the cost, which tolerance forces an extra process, which component could be standardised without touching performance.

That breakdown also tells you how the price will behave. A product whose cost sits mostly in raw material will move with the commodity market. A product whose cost sits in labour and cycle time will move with the factory’s efficiency — and with how well the process was designed in the first place.

A price you cannot explain is a price you cannot defend when volumes, materials or regulations change.

Where the difference actually shows up

The gap between the cheapest quotation and the best decision rarely appears at the factory gate. It appears months later, in places that never make it into the sourcing spreadsheet:

  • Tooling that has to be modified after the first production run, because the design was never reviewed for the process that would make it.
  • Rework and sorting on arrival, absorbed by your team instead of the supplier’s.
  • Certification that fails on a detail decided long before anyone read the standard.
  • Packaging that wastes a third of a container, paid on every single shipment.
  • Warranty and returns, which turn a one-cent saving on a component into a recurring cost with your brand attached.

How to compare quotations that are not comparable

Before comparing prices, make the products comparable. That means a technical package precise enough that three suppliers reading it would build the same thing: drawings with critical dimensions identified, materials specified by grade rather than by name, surface and finish criteria written down, test and acceptance methods agreed in advance.

Then compare landed cost per unit sold, not FOB per unit shipped: freight and duties for the real packing configuration, inspection, expected rework, cost of capital on the lead time, and the cost of the volume you will not be able to sell because it arrived late.

What to ask before you accept a price

  • What is the cost breakdown by material, process, labour and margin?
  • Which specification, if relaxed, would reduce the price the most — and what would it cost us in the market?
  • What volume was this price built on, and what happens at half and at double that volume?
  • Who owns the tooling, and what is the transfer cost if we move production?
  • Which tests are included in the price, and which ones will we be invoiced for later?
