What a Longsheng Quotation Should Itemize Before You Sign Anything

Time: 2026-11-12 09:58:03.580

The machine scope

Each machine should appear with its model, key specifications and the scope actually included: mould platen size, forming stroke, cavity count, heater zones, extruder output for sheet lines, and whether auxiliaries such as the drying and crystallising system for PET and PLA are inside or outside the price.

The commercial items

Currency, Incoterm and port, validity period of the offer, and delivery lead time stated in weeks from deposit or drawing approval, not from memory. Packing details matter for sea freight: wooden cases, film protection and whether the machine ships as one unit or in sections.

The items often missing from other quotes

Commissioning scope and duration, operator training days, the spare parts list with prices for the first year, the documentation set including electrical drawings and the parameter record, and the trial material arrangement for the factory acceptance test. Each of these has a cost; if it is not quoted, it is negotiated later from a weaker position.

What should not appear

A price marked only as negotiable, a lead time with no reference point, or a single lump sum covering machines, moulds and services without breakdown. Vague lines are where later disputes live.

Comparing quotations fairly

Align the item lists first, then compare. Two offers with different scopes are not prices for the same thing. When the items match, the residual price difference usually reflects real differences in manufacturing, such as in-house machining and testing at the builder's own plant.
