Looks like Chinese online sellers handle tariffs differently. AliExpress: 1. Some parts are shipped from the U.S., as they likely have warehouses here; over the last 1–2 years, I’ve noticed no packages originated in China -- return addresses were from third-party countries like Uzbekistan, and my latest package, received a few days ago, shipped from CA. 2. Many AliExpress vendors no longer ship to the U.S. 3. Some Ali vendors have added “import charges” to their pages, which seem close to 100%, though I’m unsure if this is already in effect. JLCPCB: They already collect a 175% tariff and handle paperwork on the buyer’s behalf to avoid surprise charges and customs delays (in theory). As a result, cheap PCB shipping isn’t available anymore, and you must use DHL or FedEx ($25–$30). LCSC: They don’t care. There are no changes on their side, so the buyer deals with customs. Worst Case: You buy from a company that doesn’t handle tariffs, place a low-value order, and get slapped with a $100 flat fee by the last-mile carrier ($200 after June 1). Currently, some sellers already collect import duties, but it’s unclear how this ties to the de minimis expiration on May 2 since JLCPCB is ALREADY collecting a 175% tariff based on the tariff FAQ on their page.
Correction: Here is an Ali package that I haven't received yet, nope, not sure how this work, but it appears that it DID ship from China:

Sounds like it was just a fast shipment, and since de minimis is still in effect, there are no issues with the customs.
