How to Compare Building Material Quotations from China

The most useful building material quotation is one you can check line by line against your project. Two offers can show the same product name and still include different materials, hardware, quantities or delivery services. Compare the scope first, then assess the price difference.

For a whole house or hotel order, a low package total may hide missing items that become expensive to source after installation begins. A clear quotation should make those gaps visible before you pay a deposit.

Give suppliers the same starting information

Send the same drawing revision, product schedule and destination details to every supplier. Identify the rooms and quantities involved, and distinguish confirmed selections from items where alternatives are welcome. If a quotation is based on preliminary dimensions, ask for that assumption to be recorded.

For custom products, request a drawing reference alongside the description. A photo communicates appearance, but it rarely defines cabinet internals, door handing, mounting details or the components included in a bathroom set.

Match the specification and pricing unit

Check the substrate, finish, thickness, dimensions, hardware model and approved sample. For cabinets, establish whether the price is per unit, linear metre, projected area or another basis. Compare the same cabinet composition; a run with several drawers is different from a run of simple cupboards.

For bathroom furniture, separate the cabinet, countertop, basin, mirror, faucet, waste fitting and mounting components. For interior doors, list the leaf, frame, architraves, seals and hardware. A product described as a set should have a written component list.

Build a comparison that reveals exclusions

Use a simple table for each supplier:

An illustrative example is a vanity offer that excludes the faucet and a second offer that includes it. The correct comparison adds the required faucet and compatible waste fitting to the first offer. It does not assume the lower total reflects better purchasing value.

Treat alternatives as separate options

If the first proposal exceeds the budget, ask the supplier to price specific substitutions. You might simplify a cabinet finish, standardize a vanity size or reduce optional storage hardware. Keep the original specification visible so the effect of each change is clear.

Do not accept a general statement such as “same quality, lower price” as the complete explanation. Ask what changed and whether it affects appearance, installation, maintenance or the documents required for the project.

Confirm the order record before payment

The final product schedule, drawings and commercial terms should agree. Record how later changes will be priced and approved. Use the payment schedule agreed for the order rather than assuming that every supplier or product uses the same deposit percentage.

Is a package discount enough to compare suppliers?

No. A discount is meaningful only against a defined scope. Confirm quantities and inclusions before comparing totals.

What should I send with a quotation request?

Send your plans, destination city, product list, finish references and target delivery dates. Identify any existing appliances or site connections that the supplied products must fit.

Put both offers into the same comparison sheet

Compare	What to record	Why it changes the result
Product	Item code, dimensions, material, finish and drawing revision	A similar name may describe a different assembly
Quantity	Pieces, area, cartons and agreed spare quantity	Different units can conceal a quantity gap
Included items	Hardware, trims, supports, fixings and accessories	The lowest base price may need extra components
Packing and transport	Packing method, named delivery point and exclusions	The product total is not the delivered project cost
Approvals	Sample reference, documents needed and release date	An unresolved specification can change price or timing

• Ask the supplier to answer every unconfirmed line in writing.
• Keep alternative materials in a separate option column.
• Approve one dated order schedule that matches the quotation and drawings.
