They are wrong. Trust science first, politics last. Note how the Scientific literature doesn’t tally with what the public health agencies tell the public.
To stay on topic, this health emergency will affect ‘manufacture and shipping’ times of all electronics and other imported products from China, as on the last count, 46 million people are on lock-down.

Q: Am I at risk for novel coronavirus from a package or products shipping from China?*
A: ‘‘There is still a lot that is unknown about the newly emerged 2019 novel coronavirus (2019-nCoV) and how it spreads. Two other coronaviruses have emerged previously to cause severe illness in people (MERS and SARS). 2019-nCoV is more genetically related to SARS than MERS, but both are betacoronaviruses with their origins in bats. While we don’t know for sure that this virus will behave the same way as SARS and MERS, we can use the information from both of these earlier coronaviruses to guide us. In general, because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures. Coronaviruses are generally thought to be spread most often by respiratory droplets. Currently there is no evidence to support transmission of 2019-nCoV associated with imported goods and there have not been any cases of 2019-nCoV in the United States associated with imported goods. Information will be provided on the 2019 Novel Coronavirus website as it becomes available’’.
2) The World Health Organisation (W.H.O) Public advice
Q)How long does the virus survive on surfaces?*
A:‘‘It is still not known how long the 2019-nCoV virus survives on surfaces, although preliminary information suggests the virus may survive a few hours or more. Simple disinfectants can kill the virus making it no longer possible to infect people’’.

3) Latest Scientific literature - Virus lives on surfaces for up to 9 days
‘‘The analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. Other biocidal agents such as 0.05-0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate are less effective’’.
