Contact Createch/Rehder Development Company for instructions prior to returning any product.

When an instrument is being returned to Rehder Development Company for repair, service, calibration, modification or any other purpose, you MUST provide the following information on all export documentation, Commercial Invoice, Airway Bill, etc.

Please provide the following on all documents....

  • The "Country of Origin" is the United States.
  • State that "Goods were manufactured in the United States and are being returned to the factory for repairs."
  • State that "Goods will be returned to your company when repairs are complete."
  • Include the Rehder Development Company serial number of the instrument for positive identification.
  • Indicate that Customs Duty charges or taxes, if any, are to be paid by the Shipper.

Failure to provide this information creates a situation where Import Taxes must be paid on the item upon its reentry into the United States. This is an unnecessary charge. Failure of the customer to provide the proper information to avoid this unnecessary cost will result in the customer being billed for those charges.
