From Tianjin to San Diego, cargo moves from North China through Tianjin Xingang, crosses a North Pacific crossing with no chokepoint but real winter-storm exposure, and is discharged at the port of San Diego.

The US side adds a 25% Section 301 duty line, forced-labour scrutiny of lithium supply chains and an ISF deadline that falls before loading. The 6 points below are particular to this lane; each comes with what we do and the paperwork it touches.

What we need to start

  • Tianjin Xingang export
  • Factory-supervised loading
  • HTS code 8507.60
  • ISF filer
  • Supply-chain tracing file

Where this route gets difficult

6 points to plan for on the Tianjin → San Diego route

They run from the Tianjin terminal through the voyage to San Diego and the United States import file.

  1. Origin port

    A slow document review at Tianjin can mean a missed vessel

    Tianjin MSA itself said in July 2026 that, under the traditional review model, long document reviews often made firms miss the vessel's document cut-off, leaving cargo in port to be re-allocated to another ship. Its new fast-track green channel (appointment-based, more than 50% faster, with a fixed document list) is for new-energy-vehicle cargo; battery shipments should not assume they qualify.

    What Anxin does: We submit the cargo report with the full document set (safe-carriage declaration, SDS, packing certificate, packaging certificate) days before the cut-off rather than on the day, and treat any MSA query as same-day work.

  2. Origin port

    At Tianjin the port slot is booked before the truck leaves the factory

    Tianjin Customs runs a 'supervised factory loading, direct loading on port arrival' model for dangerous goods: officers oversee stuffing at the factory, the declaration goes in early through the single window, and the container enters the port in a slot booked on the customs–port platform and goes straight to the ship. Any inspection happens in closed yards inside the Beijiang and Dongjiang terminals. The time saved depends on the stuffing date, the slot and the declared data all matching.

    What Anxin does: We fix the stuffing date against the vessel's DG cut-off first, then book the entry slot, and check that the declaration, the packing certificate and the container number agree before the truck leaves, so the box is not diverted to an inspection yard for a data mismatch.

  3. Sea corridor

    No chokepoint, but North Pacific storms

    The drawn corridor from Tianjin crosses the North Pacific, with no canal and no Red Sea exposure. Weather is the risk instead. In November 2020 the ONE Apus, sailing from Yantian to Long Beach, suffered a stack collapse in a storm about 1,600 nautical miles north-west of Hawaii; its owners reported that more than 1,900 containers could be lost or damaged, including up to 40 hazmat boxes.

    What Anxin does: For winter sailings especially, we review blocking and bracing on stuffing photos against the CINS points before sealing, and make sure the DG declaration is complete, so a damaged box can be identified and handled correctly.

  4. Import country

    A US-only carton mark for SP188 shipments

    Packages of UN3480 or UN3090 moving under IMDG special provision 188 skip the DG declaration at sea, yet 49 CFR 171.25(b)(3) still wants the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' mark or a Cargo Aircraft Only label on each one, and on packages of batteries with or in equipment over 5 kg net.

    What Anxin does: When the shipper declares SP188 for a San Diego booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.

  5. Import country

    Brand and chemistry labels on built-in-battery products

    California has added battery-embedded products to its electronic-waste program: from 1 January 2026 buyers pay a recycling fee at purchase, and each covered product must show the manufacturer's name or brand and the battery chemistry (or put it on the maker's website), with an annual product notice to CalRecycle and retailers.

    What Anxin does: If the goods landing at San Diego are devices with built-in batteries for sale in California, we ask the brand owner to confirm the chemistry labelling and the CalRecycle notice before shipping.

  6. Import country

    'China' has to be marked on each article or its container

    19 CFR 134.11 requires every imported article, or its container, to carry the English name of the country of origin in a conspicuous place, as legibly, indelibly and permanently as the article allows, at the time it is imported. Batteries and battery products reaching San Diego without it can be held until they are marked.

    What Anxin does: We check product and carton photos for a durable 'Made in China' marking before stuffing in Tianjin, rather than leaving it for re-marking in a US warehouse.

Documents & compliance

What to have ready: Tianjin to San Diego

Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.

At the Tianjin end

  • Stuffing date, port-entry slot and DG cut-off at Tianjin agreed in that order
  • Transport-condition classification report where applicable
  • Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
  • 'Made in China' marking on articles or containers checked on photos
  • Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report

For the shipping line

  • Stuffing photos before, during and after packing, checked for blocking and bracing
  • Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)
  • Lithium battery mark (SP188 cargo) or class 9 labels and placards

At the United States end

  • CPSC certificate data and eFiling arrangement, if the product is subject to certification
  • 24-hour emergency response number (and provider reference) for the US road leg

Before you book

Send the file once, complete

Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Tianjin filings, the carrier booking and the United States import file. We check the three against each other before the booking is confirmed.

Carriers we book with

Our booking panel; availability on this lane and acceptance of the declared UN numbers are confirmed for each booking. It does not mean that a listed carrier runs a direct service on this route. Carrier choice depends on the trade lane, cargo classification and each carrier's dangerous-goods acceptance at booking. The final carrier is confirmed on the booking.

Questions

Questions about shipping from Tianjin to San Diego

For lithium-ion batteries classified in HTSUS 8507.60.0020 and entered from 1 January 2026, USTR set the Section 301 additional duty at 25%; EV traction batteries in 8507.60.0010 have been at 25% since 2024. Other duties can apply on top. The importer's customs broker confirms the classification and total duty; we make sure the invoice gives the broker enough detail to do so.

Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.

The green channel Tianjin MSA announced in July 2026 is for new-energy-vehicle cargo. For battery containers we plan on the normal review and file early, because Tianjin MSA has said long reviews under the traditional model often cost firms their vessel cut-off.
