Hi. I have flown into (and out of) SA on many occasions with no problems. As long as the bottles are under 100ml and clearly labelled, you shouldn't have any issues. I have on the odd occasion had screening security search my bag after picking up a liquid, but I'm just patient with them and explain what it is.
Once it is cleared up, I'm off on my merry way - no hassles. Just be friendly and educational.
Thanks! I'll have my juice in checked baggage, I have to go through the red lane at customs as I have to declare 2 laptops that I am delivering to colleagues while I am there. Just didn't want to get into any trouble while I am there!
Customs, what customs? Personally I never seen them...never declared anything...
And it's JobUrg (JNB), no meeeeeuuuuuuuaaaaaaoooouuuutaaaaain like Cape Town, only "Mole heaps", no "berg" at all
But, yes, if like @johan says, just play nice
