YangMing container tracking

YMMU container tracking

YMMU is the second owner prefix registered to Yang Ming Marine Transport in the BIC register. Track it exactly like a YMLU number: all four letters, the six-digit serial, and the final check digit. Do not swap YMMU for YMLU when searching — the prefix is part of the equipment identity, so the tracking request must match the number printed on the container and the shipping documents. Yang Ming shipments also move in leased boxes with other owner prefixes; when that happens, track the bill of lading or booking number instead and Terminal49 will follow every container Yang Ming associates with it.

YMJA, YMPR, and YMSG tracking

YMJA, YMPR, and YMSG are alternate SCACs that Yang Ming files under in addition to its primary code YMLU. They are not separate carriers, and there is no separate tracking site for them. If a bill of lading, customs entry, or TMS record shows one of these codes, the shipment is still a Yang Ming shipment: paste the container, bill of lading, or booking number into the tracker above and it will resolve to the same Yang Ming feed. This matters most in the U.S., where AMS filings and arrival notices sometimes carry an alternate SCAC even though the equipment itself is marked YMLU or YMMU.

Yang Ming tracking statuses in plain English

A transport milestone says what moved, not whether the cargo is cleared or ready for pickup. In particular, vessel arrived and vessel discharged are not the same as terminal availability. Use the sequence below to decide what to verify next. Terminal49 normalizes these Yang Ming transport milestones — including rail events for inland moves and estimated-arrival updates — into one consistent timeline.

Yang Ming free time, last free day, and demurrage

Free time is the allowed period before specified charges begin. The last free day (LFD) is the final day in that period. For imports, teams normally compare the discharge time, terminal availability, holds, appointment access, and the LFD before assigning pickup. After pickup, a separate equipment-return clock may apply.

Yang Ming publishes its demurrage and detention allowances per bound, region, and container type through an official tariff lookup rather than a single rate sheet. The applicable allowance and charge depend on the governing tariff, quotation, or service contract, plus the port, equipment type, and dates — which is why this page does not publish a generic daily rate. Check Yang Ming's demurrage and detention tariff lookup for the shipment-specific figures and governing terms.

For U.S. shipments, Yang Ming's customer advisory on the FMC demurrage and detention billing rule states that import charges are billed to the consignee on the bill of lading (or to the contracted party when the consignee has not accepted the B/L or it is consigned to order), export charges are billed to the shipper, invoices are issued within 30 calendar days of accrual, and disputes must be submitted within 30 calendar days of the invoice date. Demurrage at some U.S. terminals is paid to the marine terminal operator or through eModal rather than to Yang Ming directly, so confirm the billing party on the invoice before paying.

What to do when a Yang Ming container has a hold

Start by identifying who controls the hold. A customs or government examination must be handled with the customs broker and the relevant agency. A carrier hold can require payment, original-document or telex release, or another action from Yang Ming. A terminal hold can relate to local fees, appointments, or operating requirements. The ocean milestone feed alone may not show the release needed for pickup, so do not dispatch a truck from a discharged status by itself.

Give the broker, forwarder, terminal, and drayage provider the same container number, bill-of-lading reference, terminal, hold owner, and LFD. Ask for the exact release still missing and who must provide it. If the hold prevents pickup as free time expires, preserve screenshots, emails, appointment attempts, and interchange information for any later dispute — Yang Ming's U.S. dispute window is 30 calendar days from the invoice date. Keep monitoring the timeline, because a release and a terminal availability update can arrive at different times.

U.S. terminals used by Yang Ming

Yang Ming's port and terminal directory names the facilities below for its U.S. services, shown here with each facility's CBP FIRMS code. Terminal assignments change by service loop, vessel, and booking — Yang Ming's Los Angeles calls alone spread across several terminals — so confirm the destination terminal on the current arrival notice before making an appointment.

• TraPac, Los AngelesY258
• Yusen Terminals, Los AngelesY790
• Fenix Marine Services, Los AngelesY257
• APM Terminals Pier 400, Los AngelesW185
• International Transportation Service, Long BeachY309
• Husky Terminal, TacomaZ693
• Washington United Terminals, TacomaZ705

Yang Ming tracking for forwarders and 3PLs

Logistics service providers rarely track one box at a time. Terminal49 supports shipment and container dashboards, bulk upload, direct API tracking requests, and webhook updates. The API uses the same normalized milestone structure across Yang Ming and other supported carriers, so a TMS does not need a separate status model for each line — a Yang Ming transshipment through Kaohsiung and a direct Premier Alliance sailing land in the same schema. Webhooks can pass milestone changes into an existing TMS, ERP, customer portal, or exception queue instead of making operators recheck carrier websites.

A useful exception workflow is specific: flag a Yang Ming container when an ETA changes, a transshipment discharge has no following load, discharge occurs without a pickup plan, or the box remains at the terminal as LFD approaches. Keep carrier transport events and terminal release facts distinct — that makes the alert explain what changed and which party needs to act.

Track other ocean carriers

Yang Ming sails in the Premier Alliance with ONE and HMM, so a booking made with Yang Ming can move on a partner vessel. Use the same workflow when a shipment moves with another line — each carrier page lists the supported identifiers, prefixes, official resources, and Terminal49 data coverage.
