> DHL B2C shipments to the EU are generally held in customs until the duty is paid, which makes it slow but ensures DHL isn't left holding the bag when people decide they don't want to pay unexpected import duties.
Nothing is unexpected with DHL considering the amount of paperwork they want you to fill each time :) Even if you check "retain my data for next time and don't send me this form again".
They indeed send me a payment link and i pay for customs online before the package starts moving.
I don't do Asia->EU shipments but I get prototypes maybe 2-3 times per year from the US. We gave up on DHL and are using UPS now... they want 800% less forms, cost much less and take about the same time to deliver.
Unfortunately, with DHL this can even end up costing a lot of extra as they might even start to accumulate a storage fee as they hold the package while they make sense of the documents you sent them. :P
