@artificialme, snuff.me.uk, snuffstore.co.uk (mrsnuff) and toquesnuff.com do ship to Indonesia. I would risk and place a small order, not exceeding Indonesia’s allowed 45 g limit. Just bear in mind that customs most probably would count the weight of containers (tins, tap boxes etc) as well. You might consider buying snuff in lightweight sachets (for instance: http://snuff.me.uk/proddetail.asp?prod=PGA25, https://snuffstore.co.uk/photo-kailash-p-807.html, https://snuffstore.co.uk/rosinski-c-177.html).
Rosinski does ship worldwide (shipping fee is EUR 6 to any country). All Rosinski snuffs are available in 10 g sachets. https://rosinski-schnupf.com/webshop/en/
Toque offers economy bags: https://www.toquesnuff.com/index.php?app=gbu0&ns=catshow&ref=50g-economy-bags). You might ask Roderick to reduce the weight down to 45 g (I believe Roderick would do that or even resend you the snuff in seizure’s case).
McChrystal’s send worldwide and offer free standard delivery on all orders of GBP 15 and up: https://www.mcchrystals.co.uk/snuff
northerner.com ships to Indonesia, too: https://www.northerner.com/int/more-products?cat=2068
All these vendors do ship to Holland as well.
And here’s the Dutch online snuff seller for Holland’s inland orders: https://www.rokado.nl/snuiftabak.html
If you haven’t tried those 5 Poschls, I recommend ordering all of them. Be warned, they all are mentholated.
