You can never be too careful in double checking whether you need to apply for an export licence issued by the Export Control Organisation (part of the Department for Business (BIS)) since the list of controlled goods is quite extensive and wide ranging.
Your first point of call to answer this question should be to look at the guidance on the GOV.UK website - https://www.gov.uk about 'strategic exports: when to request an export licence') to understand more. (https://www.gov.uk/do-your-goods-need-an-export-licence)
In a nutshell you need to check if you the products you are exporting are listed on the UK Strategic Export Control Lists (current list was published in August) - (https://www.gov.uk/uk-strategic-export-control-lists-the-consolidated-list-of-strategic-military-and-dual-use-items). .
Items on this list include miiltary and dual-use goods and include items such as valves and ball-bearings. Note this list does not include commercial product names or titles.
If dual-use items are listed then the controls depend on the performance capability of the items. If your items are standard, off the shelf, commercial products (ie not specially designed or modified for military use) then they are not likely to be listed on the Control Lists.
Besides double checking the Control Lists, you should also be aware of the guidance about sanctions on Syria (https://www.gov.uk/sanctions-on-syria) and should also consider the issue of end-use controls and maybe consider making an End-User Advice Service request (via the SPIRE website - https://www.spire.bis.gov.uk) if you definitely know that the items are not listed on a Control List.
