Core return policy

Exchange terms must be agreed before shipment.

A core return applies only when the written quotation or sales document expressly identifies the order as an exchange arrangement.

Last updated · 9 September 2026

1. When this policy applies

A core return is required only when the final written quotation, pro forma invoice or sales contract expressly identifies the transaction as an exchange or core-return arrangement. An outright sale does not require a core return unless the applicable transaction document states otherwise.

2. Written terms required before shipment

Before an exchange order is accepted, the written transaction document should identify, as applicable:

  • The eligible transmission or core type and required identifying code
  • Any core charge or deposit
  • The return deadline and expected condition
  • Packaging, transport and customs instructions
  • Freight, duty, tax and insurance responsibilities
  • The inspection process and treatment of any credit or deposit

No standard deposit amount, return period or refund timetable is promised on this website.

3. Return authorisation

Do not ship a core without written return instructions and an agreed return reference or RMA. The production-site address shown on the website is not automatically a return-shipping address. The correct consignee, address, contact, customs description and shipping method must be confirmed in writing for each return.

4. Identification and condition

Before shipping, the buyer may be asked for photographs of the complete unit, codes, labels, casing, connectors, visible damage, missing components and prepared packaging.

Acceptance and any applicable credit are determined only after the returned core is received and inspected under the agreed terms. Product-specific acceptance criteria must be confirmed before shipment.

5. Fluids, packaging and transport

Do not ship a core until oil handling, packaging, carrier and customs requirements have been agreed. Freight, duties, taxes, insurance, damage in transit and unauthorised returns are handled according to the written transaction document.

6. Inspection and financial treatment

Receipt of a returned core does not guarantee acceptance, full credit or refund. Inspection timing, valuation, deductions, rejection handling and treatment of any core charge or deposit must follow the applicable quotation, pro forma invoice or sales contract.
