Hardware returns

Electronic instrumentation eventually needs re-calibrating and sometimes it may fail. So you may wish to send it to CED and get it back, fixed. We would like to help. If you are not in the EC, there is a strong risk of wasting money on needless taxes and customs duties, unless you use the correct procedure.

When returning hardware to CED for repair, servicing or re-calibration, we have a returns procedure that you must follow.

Firstly, make contact, either by phone (Int.+44) (0)1223 433477 – Hardware helpdesk, or email hardhelp@ced.co.ukand we will assist you with the returns procedure that will get the most efficient and cheapest possible transit of your goods, which will hopefully save you money and time.

You will be asked about your hardware problem, and possibly given some suggestions to try, to make sure that the unit really does need to be sent back to CED.

If it is to come back, you will be given an RN number, and this will be logged onto our database. You must not return equipment to CED without an RN number.

Shipping details for Temporary returns

Please pack the unit in our original packaging, or in a strong double-walled cardboard box with plenty of cushioning material between it and the box. The box should not be too big or you will pay an unnecessary amount for carriage.

Ship by:

Federal Express, UPS, or DHL Worldwide (in that order of preference).
Use of DHL International will significantly increase costs and is not recommended.
Do NOT use TNT or a freight forwarding company.


Ship Express CIF door to door.
The sender must pay carriage charges.
Tell the shipper that it’s a "Temporary export to UK for repair", if you are outside the UK.

Ship to:

  • CED Returns, RN????,
  • Technical Centre,
  • 139 Cambridge Road,
  • Milton
  • Cambridge CB24 6AZ

If you are outside the EC, produce a commercial invoice for customs by writing the following details on your official letterhead (4 copies will be required):

  1. Your name and telephone number
  2. CED’s name and address as the "consignee", Paul Mappledoram as contact name
  3. Customs Procedure Code (CPC) 5100A04
  4. Commodity Code 8471 6070
  5. Brief description of the goods and reason for return, i.e. "1401 system unit S/No. P2249 for repair in the UK"
  6. Duration of repair, say two weeks
  7. Value for customs purposes @ £200 GBP

It is very important that the shipper and customs know that it is a temporary export. Only then will the correct export procedures be followed, making it cheaper and quicker.

The following section is very important: please ensure you understand it, and carefully follow the instructions. If the goods are imported incorrectly, CED may refuse to accept the item you return.

Preparing the Airwaybill:

  1. In the Commodity Description box write “Temporary import to the UK for repair - scientific digital data recorder”.
  2. If there’s an export box marked “Temporary”; check it, cross it or tick it.
  3. If there’s a box for payment of Duties & Taxes; DO NOT check or tick any box. Instead, write “Temporary Import Only”.
  4. If there’s any spare space on a paper Airwaybill, write in block capital letters “TEMPORARY IMPORT INTO THE UK FOR REPAIR”.
  5. When the courier collects the package, tell them verbally that it’s a temporary export from your country to the UK for repair. If it’s with FedEx, ask them to affix a ‘Control’ label to the box.

Privacy policy

CED, through this site, does two things that relate to privacy. We would like to explain them.

Emails from down-loads

We offer free down-loads of many files on our site, from test programs to complete install files for updated versions of major packages like Spike2 and Signal.

When customers wish to take a down-load of a major package, we ask a few questions, including their name, email address, the serial number of the software for which they seek an upgrade and whether they would like an automatic email whenever we update the product. This information is emailed back to CED when they access the final down-load screen. Within this email, your browser transmits the type and version of browser you are using, and the screen resolution you are running.

The reasons why we take and keep this information are that it is useful for our software development team to know who has taken the latest versions, and it is useful for our web site development team to know which browsers people are using to view our site, and what resolution they have their screens set to.


When people down-load a major package, we try to write a cookie, a small file in your computer, that records your name, serial number of the software package, and the version you are down-loading. These files have a lifetime of one year.

The reasons for storing this information are firstly that if you ask for another down-load some other time, your details are read from the cookie and are pre-written into the form, to save you looking them up again. The other reason is that next time you access our site, your browser looks through your CED cookies and compares the versions down-loaded with the latest version numbers read from our site. If there is a later version of a product you have already down-loaded, we tell you on the home page screen, so you know that it is worth going to the down-load page again.

None of this information is ever given to anyone outside CED. ×
