The short version

Thirteen stories this week. The dates that need action soonest: the UPS demand surcharge starts October 25, Poshmark starts deducting overweight label costs October 26, and eBay balance terms apply to existing US sellers November 4. One date moved later: US mail that owes Section 301 duty can keep the postal informal entry until January 20, 2027. And a cost that moved quietly: a ¥100,000 China order paid in yuan costs $784.59 more than a year ago at the official reference rate.

Also confirmed this week (not briefed)

  • Dual-use item export checks: MOFCOM and the General Administration of Customs issued Announcement No. 52 of 2026 on October 19, in force the same day. When customs questions whether an export may be a controlled dual-use item, the exporter has 7 working days to provide documents; customs then has 15 working days to decide or refer the goods to MOFCOM, which has 15 working days to identify them. Time for submitting documents and for testing is not counted. The goods are not released during the review, and the rules also apply to cross-border e-commerce, mail and express shipments. If a supplier's shipment is held for such a check, ask for the customs notice and allow extra time.
  • Freight: the Shanghai Containerized Freight Index was 3,681.34 on October 23, up 1.76 points from October 16.
