Here at Sema, given the continuous media attention, Coronavirus is very much at the forefront of our minds and that of our customers. As to be expected, we have had a small number of requests for information on how we intend to deal with potential impacts from the Covid-19 outbreak.

WE HAVE GOOD STOCK LEVELS OF MOST CORONAVIRUS RELATED PRODUCTS, so call or email our office for more details.

As with any business, in the first instance we are obliged to operate safely and within the specific Government Guidelines that may be issued concerning the outbreak. We will of course comply fully with this guidance at all times.

Secondly, we have identified a number of potential risks to our service to you and, as a responsible supplier, please be assured that we are taking measures to manage this fluid situation to ensure a continuation of supply/service to all of our customers.

At a more operational level, the most likely short term impact is the interruption of the supply of imported goods from affected areas, particularly China manufactured products. As lead times from the far east are the longest in our supply chain, we have been working on mitigating these risks for since Mid-February already.
We currently do not expect significant problems with any particular product lines, but where we have identified specific risks, we are putting alternative supply options in place to minimise the impact for any of our customers.

Lastly, we appreciate that many of you will be drawing up plans for managing risks and potential impact at your sites. If you have any additional measures that you require our field personnel to comply with when visiting your sites, please let us know what these measures are so we can inform our staff appropriately.

Whilst it is not possible to guarantee anything in this sort of scenario, we believe we have been both proactive and decisive to deliver the best possible service for our customers. If you do have any specific concerns please do not hesitate to speak to your normal contact at Sema on 01302 328887 or designated mobile number contact.
You can also email with any queries you may have.
