I have had my JLCPCB orders shipped via their "Europacket" option multiple times, and found it quite attractive. They bundle your order with those from other European customers and ship a big box via fast airfreight to their import agent in Germany. The importer takes care of customs processing for the whole lot, then splits up the contents of the box and remails them to the individual customers via regular local mail or DHL.
This has worked well for me: You prepay the net import duties to JLCPCB upon order and avoid DHL's extortion fee for customs handling, and you get relatively fast shipment at a reasonable cost.
But lately, all my EuroPacket orders have taken longer than expected. Two of them were sitting at the European import agent (Patac GmbH, Weixing Wu) for days before being remailed. The current one sits in customs since Tuesday, with the DHL tracking status saying "A DHL representative shall attempt to contact importer or shipper...", so it seems the import agent is unresponsive. I only found that out by contacting JLCPCB, by the way, because their online tracking for the first leg of the journey is broken.
Have others experienced the same, or is it just a streak of bad luck for me?
