How OEM Machine Quotations Are Structured: Base, Options

When you request a custom or OEM machine quotation from a Chinese builder, the reply usually arrives as a structured offer: base machine, options, packing, trade terms, validity. Buyers who understand this structure compare offers faster and catch the games some suppliers play with missing lines. Having quoted custom machines for over a decade, here is how the document is built and where to look closely.

Line 1: The Base Machine

This line carries the machine model and its core configuration: travels, table size, spindle taper and speed, tool magazine capacity, control system and the guide way type. Everything on this line defines the machine's capability; everything else is either an addition or an assumption. Check that the control brand and model, the spindle motor power and the accuracy figures are written explicitly, not referenced to a brochure. Accuracy matters here: standard VMC positioning accuracy typically falls around ±0.01 to 0.02 mm, precision grade around ±0.005 mm, and the price difference between the two grades is real.

Line 2: Options and Upgrades

Each option should appear as its own priced line: 4th axis, angle heads, chip conveyor, through-spindle coolant, higher spindle speed, upgraded control, linear scales, stabilizer. Watch for two things. First, options quoted as "included" without specification, which usually means the cheapest available version. Second, options you asked about that are missing entirely, which sometimes means the factory cannot supply them and hopes you forget. For OEM orders, private label items such as nameplates and manual language belong in this section too; they are often free or nominal, but they should be written down.

Line 3: Tooling and Commissioning

Across the industry, tooling, installation and training commonly add 20 to 40 percent over the machine price. A quotation that shows only the machine invites an uncomfortable surprise. Ask which of these are in the offer: cutting tools and holders, fixtures, coolant system plumbing, installation and leveling at your site, commissioning runs, operator training, and a recommended first-year spare parts package. Some buyers source tooling locally to save freight and import duty; either way, the quotation should state what the factory supplies and what it does not.

Line 4: Packing

Export packing deserves its own line: seaworthy wooden case, rust-proofing, silica protection, fixation steelwork inside the crate, and marking. For humid destinations, ask explicitly about corrosion protection, because a machine that sits in a tropical port for weeks needs it. Packing is rarely expensive, but machines have been ruined by its omission.

Line 5: Trade Terms and Validity

The quotation must state the trade term: ex-works, FOB, or CIF, and the port. This decides who pays for inland transport, ocean freight and insurance, and it is the most common source of confusion between quotes from different suppliers. Check the validity period (quotations often hold for 15 to 30 days, because steel and spindle prices move), payment terms, and the lead time in days from deposit or drawing approval.

Comparing Two Quotations Honestly

• Normalize the configuration: same control, same spindle, same accuracy grade before comparing totals.
• Normalize the trade term: convert everything to ex-works plus freight, or CIF from the same port.
• List every missing line: an offer without tooling, packing or training is not cheaper, it is incomplete.
• Check the lead time and the price validity date together; a long validity at a low price sometimes hides a slow delivery schedule.

For reference, listed trade pricing in 2025-2026 ran roughly as follows: entry 3-axis VMCs with a Chinese control from about USD 18,000 to 40,000, machines with Fanuc or Siemens controls from about USD 45,000 to 90,000, heavy gantry machining centers from about USD 150,000 to 450,000, and 5-axis machining centers from about USD 100,000 to 300,000. Treat these as market bands, not quotes.

A well-structured quotation is itself a quality signal. Factories that quote line by line, with explicit specifications, are the ones that build machines the same way.
