Transpacific Eastbound (Asia → North America) Shipment Tracker

It's a speed-versus-variance trade: WC+rail wins on paper (3–7 days faster to the Midwest) but inherits rail dwell volatility; all-water via Panama is slower and steadier. Shippers burned by ramp congestion often split volumes 60/40 and let quarterly performance data (log it here) adjust the ratio.

Published schedules say 14–20 days to the West Coast, 25–32 via Panama to the East Coast. Reality adds origin dwell, destination clearance and the lane's specific friction (west coast labor cycles and rail inland capacity are the recurring chokepoints). Your own log is the honest answer: after 15–20 shipments the actual door-to-door distribution — including the tail — is sitting in your CSV export.

Pre-Golden Week (late September) and pre-Lunar New Year (January) sailings book out weeks ahead and roll the unlucky. Peak behaviour to expect: space sells out earlier, rollover risk rises, rates firm, and the lane's chokepoints run hotter. Rows you add in those windows should carry earlier bookings and more conservative ETAs than the same route in the slack months.

Because lanes have personalities — different chokepoints, peaks and failure modes — and mixing them averages the signal away. A dedicated board per major lane keeps the dataset clean: this lane's transit distribution, this lane's exception causes, this lane's carrier ranking. That's the granularity rate negotiations and buffer-stock math actually need.
