Yang Ming operations in 2026
Yang Ming Marine Transport Corporation is headquartered in Taiwan and sails in the Premier Alliance. Bookings, shipping instructions, and bills of lading run through Yang Ming's own channels, the e-Service portal and EDI, while tracking adds a DCSA Track & Trace API path. The first thing a forwarder has to get right is the filing code.
The YMJA filing code. Effective 1 October 2023, Yang Ming moved its bill of lading number prefix and its EDI and AMS filing SCAC from YMLU and YMPR to YMJA. The registered carrier SCAC stays YMLU, and the container box prefixes (YMLU and YMMU) are unchanged. A forwarder still transmitting AMS under YMLU is using a stale code. Getting this split right, the registered SCAC on one side and the filing code on the other, is the first requirement for clean Yang Ming documentation.
Premier Alliance. Yang Ming sails with ONE and HMM in the Premier Alliance, effective 9 February 2025 for a five-year term, across the five East-West mainline trades: Asia to North America West Coast, Asia to North America East Coast, Asia to the Mediterranean, Asia to North Europe, and Asia to the Middle East, with an MSC slot-exchange on the Asia-Europe trade from February 2025. The Premier Alliance replaced THE Alliance after Hapag-Lloyd left for Gemini. A Yang Ming booking on a mainline East-West service may sail on ONE or HMM tonnage; the booking confirmation names the operating carrier.
Schedule reliability. Sea-Intelligence GLP #178 (April/May 2026, trade arrivals) puts Premier Alliance reliability at 54.0%, the lowest of the four major alliance groupings. That is an alliance-level figure; no Yang Ming carrier-level reliability figure is published. Forwarders booking Premier Alliance services should treat schedule reliability as a watchpoint, not a fixed number.
What Expedion handles for Yang Ming
All five operational workflows, on one page.
Booking. Yang Ming e-Service (e-solution.yangming.com) is the carrier-owned booking platform: new bookings and booking history online, reusable booking templates, and business-partner maintenance. On Premier Alliance mainline East-West services a Yang Ming booking may sail on ONE or HMM tonnage, so the operating-carrier caveat applies and the booking confirmation names the operating carrier. Contract and spot rate specifics, and any booking-amendment fees, sit behind tariff and login walls and are not stated here.
Shipping instructions. e-Service accepts B/L instruction submission through three documented channels: the portal, with reusable B/L-instruction templates, FAX, and EDI. The portal also offers SOLAS VGM submission with a container tare-weight query. SI, CY, and VGM cut-off hours sit behind login and are not stated here; Expedion agents work the documented channels.
Bill of lading. Yang Ming e-Service supports customer self-print of bills of lading at no additional cost, delivery of the Seaway bill as a PDF by email, and a B/L Contents view restricted to the service-contract holder and the bill of lading parties. As a DCSA member, Yang Ming has implemented Bill of Lading 3.0 Beta. Bill of lading amendment fees and turnaround times are not sourced and are not stated here.
Documentation. VGM, dangerous-goods declarations, and advance manifest filings. US AMS is filed under SCAC YMJA effective 1 October 2023, in the N9 and RFF segments; the registered SCAC and the container box prefixes stay YMLU-based, and a forwarder still filing AMS under YMLU is using a stale code. For the EU, the Entry Summary Declaration is lodged via ICS2, the EU regime mandatory for sea carriers from 3 June 2024 and for house-level filers from 4 December 2024. No Yang Ming-specific surcharge is stated here, and no figure is ported from another carrier.
Tracking. This is where Yang Ming differs most from a portal-only carrier. Yang Ming is a DCSA member with Track & Trace 2.2 implemented and a documented API portal at e-solution.yangming.com, so a standards-based Track & Trace API path exists, alongside e-Service Shipment Management (booking and B/L processing status, with cargo tracking) and EDI. On Premier Alliance legs, milestone events originate from the operating carrier's system, so agents identify the operating carrier per booking and reconcile milestones accordingly.
Yang Ming's fee schedules, including any bill of lading amendment, manual shipping instruction, and ENS or ICS2 surcharges, sit behind regional tariff pages and login walls, and the amounts vary by region. Pages on this site cite validated figures only and mark un-sourced geographies as gaps rather than inventing numbers.
TMS compatibility
Expedion agents operate Yang Ming workflows on top of your existing TMS, connecting through EDI and Yang Ming e-Service browser sessions. Yang Ming is a DCSA member with a Track & Trace 2.2 API, so the integration pattern is API-where-available for tracking, plus portal sessions and EDI for booking, shipping instructions, and bill of lading flows. Your system of record stays intact.
Frequently asked questions
What SCAC code should I use for Yang Ming AMS filing?
The EDI and AMS filing SCAC and the bill of lading number prefix are YMJA, effective 1 October 2023, replacing YMLU and YMPR. The registered carrier SCAC and the container box prefixes (YMLU, YMMU) remain YMLU-based. A filing still transmitted under YMLU is stale. Expedion agents file Yang Ming AMS under YMJA and keep the registered-SCAC and box-prefix distinction straight.
Does Yang Ming have a DCSA Track & Trace API?
Yes. Yang Ming is a DCSA member and has implemented Track and Trace 2.2, along with Bill of Lading 3.0 Beta and Operational Vessel Schedule 3.0, with a Yang Ming API portal, so programmatic tracking has a standards path. e-Service Shipment Management and EDI also cover tracking, with operating-carrier-aware handling on Premier Alliance legs.
What is the Premier Alliance and who is in it?
ONE, HMM, and Yang Ming, effective 9 February 2025 for a five-year term, across the five East-West mainline trades, with an MSC slot-exchange on the Asia-Europe trade. A Yang Ming booking may sail on ONE or HMM tonnage, so check the operating carrier per booking.
