Terms of sale: quotation, payment, delivery and warranty
The terms of sale below are the ones that apply to a Kerke quotation unless the contract says otherwise. They exist to make the two things buyers argue about — output and delivery — explicit before the order, not after it.
Terms of sale at a glance
Quotations are valid 30 days. Standard payment is 40% with the order and 60% before shipment, L/C at sight for larger lines. Delivery follows the Incoterm named in the quotation. Warranty is 12 months from commissioning or 14 months from shipment, whichever comes first. Output figures on this site are reference values; the guaranteed figure is the one measured during the material trial and written into the contract.
Quotations
Quotations are valid for 30 days from the date of issue unless stated otherwise, because gearbox, motor and steel prices move. Prices are exclusive of duties, taxes and local charges in the destination country. A quotation covers the machine scope listed in it and nothing that is not listed: utilities, foundations, local labour, inbound freight from the port and installation materials are the buyer's scope unless the quotation says otherwise.
Specifications and reference output
Capacity figures published on this site are reference values at standard screw speed with a stated material. They are useful for comparing configurations; they are not a guarantee. The guaranteed output is the figure measured during the material trial, written into the contract, and re-measured at commissioning on the same material and the same pellet standard.
Where a buyer's material differs from the trial material — different filler grade, different mesh, different MFI — the guarantee follows the trial material, and a new trial is the honest way to move it. The sizing logic is explained in the selection guide.
Payment
| Structure | Split | Typical use |
|---|---|---|
| Standard | 40% deposit, 60% before shipment against copy of B/L | Single line, repeat customer |
| Letter of credit | L/C at sight, confirming bank acceptable to both sides | Larger lines, first order |
| Multi-line project | Milestones per machine, agreed in the contract | Turnkey plant |
Delivery and Incoterms
Delivery follows the Incoterm named in the quotation — usually FOB Shanghai or Ningbo, or CIF to the destination port. The Incoterm decides who pays freight, insurance and unloading, and where risk passes; it does not decide who clears customs at destination, which is normally the buyer. Machines are packed sea-worthy for 30–45 days of ocean transit, with the electrical cabinet and instruments crated separately.
Warranty
Twelve months from commissioning or fourteen months from shipment, whichever comes first, covering design, material and workmanship faults. Excluded: wear parts (screw elements in the wear zone, cutter blades, heater bands, screens, seals), damage from operation outside the agreed parameters, and damage from unauthorised modification. Warranty work is done by replacing or repairing the part; travel and accommodation for an on-site visit outside the commissioning window are quoted separately.
Inspection and claims
Inspection before shipment is welcome: at our works, by video, or by a third party such as SGS, TÜV or BV at the buyer's cost. Claims for shortage or transit damage should be raised within 7 days of arrival, with photos of the packing and the damage, so that the insurance claim can be filed while the container is still being unloaded.
Intellectual property
Screw configurations, drawings and process parameters supplied by Kerke remain our property and are provided so the buyer can operate and maintain the delivered equipment. They may not be used to manufacture spare parts or a competing machine. What ships as documentation is listed on the certificates page; the data we hold about an enquiry is described in the privacy policy.
