I hope I'm correct but frankly, I think people are making an unnecessary big deal out of this.
There were already limitations to the value of imports for some time now. Now, they actually give some limits on some items which overall increases the value of what can be brought in.
Obviously, this new rule applies to new products bought overseas and is clearly aimed at the grey import market. Such rules exist in so many other countries as well.
As for the profiling, frankly I don't see it happening. I landed at Soetta last week from overseas, just a day after the implementation of the rule. I saw both Indonesians and foreigners alike being sent to the jalur merah. The bule in front of me was sent to jalur merah and I was sent to the green. It's just a matter of luck, really.
A friend of mine landed days later, Indonesian, who specifically did some shopping in Europe because it's cheaper for branded items. They got sent to the jalur merah and got hit with import duties because they were not aware of the new rules which had just come out.
It is what it is, but realistically, like everywhere in the world, they will never be able to check every passenger. And if you are just a regular traveller not bringing 3 suit cases of full of luxury bags, electronics, alcohol and medicine without a script, you don't have anything to worry about really.
Funnily, I still see people selling jastip services... I guess this will come to a stop now.
