Singapore adds PDT requirement for Cat. II countries; closes Germany loophole

From 10 September onwards, travellers from Cat. II countries must undergo a PDT. Here's the details, and what it means for Germany travel.

Singapore has announced an updated set of border measures, which take effect from 9 September 2021, 2359 hours. 

In short, the window for a pre-departure PCR test (PDT) before returning to Singapore will be shortened from 72 to 48 hours, and will be a requirement for Category II countries/regions as well.

Singapore will also add eight more countries to the Category III list, allowing fully-vaccinated travellers to serve their SHN at home instead of in a hotel. 

PDT now required for Cat. II countries

From 9 September 2021, 2359 hours, all inbound travellers entering or transiting through Singapore from Category II, III and IV countries/regions must produce a negative PDT taken within 48 hours of departure. 

This supersedes the old rule whereby Category II was exempt from the PDT requirement, and Category III/IV could do the PDT within 72 hours of departure.

Cat IV: All other countries/regions
VTL (from Sept 8): Germany, Brunei

This adds a potential complication for anyone returning from a Category II country/region. Remember, ICA states that individuals should not travel to Singapore if they:

  1. Have symptoms of COVID-19;
  2. Are diagnosed or suspected to have COVID-19 infection in the last 21 days before departing for Singapore; or
  3. Had close contact with any person with COVID-19 in the last 14 days before departing for Singapore

If your PDT is positive, you’ll have to delay your return to Singapore by at least 21 days. 

Impact on travel from Germany

All travellers to Singapore must now undergo a pre-departure PCR test in Germany, regardless of which scheme they intend to enter under

The addition of a PDT to Category II countries effectively kills the Germany “loophole”, where some travellers might have found it more beneficial to be ignorant of their COVID-19 status. 

I elaborated how that would work in this post, but to summarise, travellers from Germany to Singapore have the choice to travel under the VTL or Category II (aka non-VTL). 

  • VTL travel from Germany requires a pre-departure PCR test
  • Testing positive would mean 14 days of self-isolation in Germany (the lab is obligated to inform the local health authorities), and an overall delay in returning to Singapore of at least 21 days
  • Category II travel from Germany did not require a pre-departure PCR test
  • Instead of rolling the dice with a PDT, a traveller from Germany might opt to take a non-VTL flight and enter under Category II rules.
  • He/she would still have to do a 7-day SHN at home, but that’s arguably better than a possible 21-day (self-paid) stint in Germany

Another unintended consequence was the possibility that an individual might take a self-administered ART in Germany, then decide how to fly back based on the outcome. 

If he tested positive, he might opt to return to Singapore via a non-VTL flight, so as to avoid a positive PDT in Germany. He’d likely test positive on arrival in Singapore, but wouldn’t be on the hook for a 21-day stay in Germany. 

If he tested negative, he could then proceed to do the PDT and fly back on a VTL flight, avoiding any SHN.

Never mind the ethicality of boarding a plane while knowingly being a COVID risk, or the fact you’d be lying on your Singapore arrival card (one question asks if you are diagnosed or suspected to have COVID-19 in the past 21 days)- the incentive was there, and it needed to be snuffed out. 

The addition of a PDT requirement for Category II countries brings the VTL/non-VTL route onto relatively more equal footing. 

  VTL Category II
SHN None 7-days at home
PCR tests 4 3
Flights VTL flights only Any flight, so long as it does not transit in Category III or higher country
Additional 21-days overseas? Possible Possible
Available to Vaccinated only Anyone

The main incremental cost of VTL travel is now a single additional PCR test, which I think most people would be willing to undergo for freedom.

However, the Category II/non-VTL route still has some advantages worth highlighting:

  • VTL travellers must take non-stop flights, but non-VTL travellers can take a flight with a transit in a Category I/II country and be no worse off. For example, they could take a transit flight through Hong Kong and still qualify for a 7-day SHN on arrival in Singapore
  • Singapore Airlines is only releasing Advantage award space on VTL flights, while non-VTL flights have Saver award space
  • VTL requires travellers to be fully-vaccinated, ruling it out as an option for families with children under 12

New additions to Category III

In other news, Singapore will be adding the following countries to Category III:

  • Croatia
  • Egypt
  • Finland
  • Malta
  • Netherlands
  • Poland
  • Saudi Arabia
  • Sweden

Fully-vaccinated travellers from these countries may choose to opt out of dedicated SHN facilities and serve their 14-day SHN at home.

  Fully-Vaccinated Unvaccinated
VTL No SHN Not allowed
Category I No SHN
Category II 7-day SHN
Category III 14-day SHN
14-day SHN
Category IV 14-day SHN

If the situation continues to improve in these countries, they could be candidates for an upgrade to Category II and/or addition to the VTL scheme.  Here’s how each country currently treats travellers from Singapore (source: Kayak)

Country Entry for SG residents
Fully-vaccinated Unvaccinated
Croatia ✅ No quarantine ✅ No quarantine
(PCR test)
Egypt ✅ No quarantine ✅ No quarantine
(PCR test)
Finland ✅ No quarantine ✅ No quarantine
Malta ✅ No quarantine ✅ No quarantine
(PCR test)
Netherlands ✅ No quarantine ✅ No quarantine
(PCR test)
Poland ❌ No entry ❌ No entry
Saudi Arabia ✅ No quarantine
(PCR test)
❌ No entry
Sweden ✅ No quarantine ✅ No quarantine
(PCR test)


Singapore’s addition of a PDT to Category II countries feels like a step backwards in some ways, especially since Category II measures make no distinction between fully-vaccinated and unvaccinated travellers. It would certainly make Singapore residents think twice before travelling over there. 

On the other hand, it does resolve a potentially tricky issue with travel from Germany specifically, removing the incentive for individuals to be willfully ignorant of their COVID status. 

None of this has any bearing on the VTL per se, although it does change the calculus involved in deciding between VTL/non-VTL travel.

At the end of the day..there’s still no way to travel with a peace of’s counter productive to have the pre-departure PCR test for the VTL flights when the Govt has been been saying “we will need to live with Covid-19 in our midst and vaccination is key” what is what?

I’m at peace with the risk of catching Covid in Germany(although low but you can’t rule it out) but having to stay another 21 days at the end of a planned 12 days trip..nah man..


Well, it can become a political issue, thus the reopening is still so slow…


Yup the many tests and still reporting on daily cases is quite contradictory to what the government has described would happen during the “endemic phase”, also taking into account that we are not over 80% fully vaccinated.

It seems they’ve put some brakes on the policy.


now* over 80% fully vaccinated.


Air travel will not really take off if the government insists on having pre-departure tests. It doesn’t make sense that we have one of the highest vaccination rates but still have so many restrictions…


I guess we just have to wait for natural selection to take its course and our population would be a lot more robust against the virus.


That’s the right decision, at least for flights which cater to the unvaccinated.

I wish you would not call it a “loophole”, Aaron, as that automatically makes it sound as if somebody had made a mistake somewhere. At the end of the day the absence of another PCR test made it that little bit more attractive for parents with children to travel without having to go through the ordeal of having a swab shoved up to very unpleasant heights. And you talk about people “abusing the system”. While in theory that may have been possible, I bet that the vast majority of people would have stuck to the rules. Also bear in mind… Read more »


I fully agree. Instead of removing PDT from VTL, now we are slapped with a PDT for category II travel.

In general, the miles and points community has a slightly unhealthy preoccupation with finding loopholes and exploiting them (as evidenced by many comments suggesting masking their intra-EU travel under the VTL). Or perhaps it is a uniquely Singaporean thing. Except in this case, said community likely also includes many dutiful public servants who may/may not work for MOH/ICA/CAAS…

Malta, Croatia, Sweden are some nice additions for a hotel quarantine free Euro trip.


For Cat II entry, is the 21-day since last Covid-19 infection requirement still there? I noticed it’s on the VTL details but I don’t find it (or missed it) from the Cat II document.

[Edit: Ok it is in the Overview section not specific to Cat II]

That’s a question on the arrival form every passenger needs to fill out prior to departure independent from the lane he/she’s using.

I have a question – if I come back via non VTL flight from Germany, but for personal reasons, I need to find a hotel to do 7-day SHN. How does that work? Do I book any hotel for 7 days to stay there or there needs to be a specific type of hotel that I need to book to? I wonder if I can find one of those small serviced apartments to serve the 7-day SHN.


For Cat II countries (such as Germany) you can do the 7-day SHN anywhere, so long as you are isolated in a room with toilet. So you can book any type of accommodation including service apartments etc.


Most likely someone shoved something down and didn’t give their staff time to sync things across. Cat I & II have always been there. No PDT made sense both politically and scientifically (or some balance). Then came VTL which they wanted to extract max political mileage. But they forgot about the Cat II no-PDT. So it’s not a loophole but something slipped.


SQ has now opened up quite a bit of Saver space, so it’s not just Advantage only (good news for once!). Just got my waitlisted VTL now. However, it looks like the $125 I already paid for my prior return authorization are forfeited with the cancellation of that pass in favor of the newly applied and paid for VTP.

I can’t find details anywhere, but would it be possible to travel between multiple cat 2 and cat 3 countries within a 21 day period and serve SHN at a facility of my choice I.e. at home?

VTL flight is actually more expensive
