This route runs out of Shenzhen's Yantian and Shekou terminals, then follows a North Pacific crossing with no chokepoint but real winter-storm exposure; at the far end is the port of Pittsburg.

The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. 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

  • Typhoon season Jun–Oct
  • Yantian / Shekou export
  • Supply-chain tracing file
  • HTS code 8507.60

Route profile

The Shenzhen → Pittsburg route in brief

Sea corridor

Transpacific (North Pacific)

A North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.

Import country

United States

Section 301 duty on Chinese lithium-ion batteries at 25% since January 2026, UFLPA scrutiny of lithium supply chains, ISF 24 hours before loading, and a US-only marking rule for SP188 packages.

Where this route gets difficult

What to watch between Shenzhen and Pittsburg: 6 points

In the order the cargo meets them: at the loading port, at sea, at Pittsburg and at customs in United States.

  1. Origin port

    Typhoon season squeezes Shenzhen cut-offs

    The Hong Kong Observatory puts the regional tropical cyclone season from June to October, busiest July to September. DG containers need their MSA filings approved and a signed packing certificate before loading, so a closed gate or a rolled vessel in typhoon weeks can push the whole document chain to a new sailing.

    What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.

  2. Origin port

    Factory stuffing in Dongguan, loading at Yantian: avoid a second opening

    Much Shenzhen battery export is stuffed inland and trucked to the terminal. In May 2026 Yantian MSA and Dongguan MSA ran a cross-regional 'one-box' pilot: four battery containers were inspected jointly at the Dongguan factory and loaded at Yantian without being opened again. It shows that the inspection record made at the factory is what matters at the terminal.

    What Anxin does: We ask at booking whether your factory and the terminal's MSA office can use the one-box arrangement, and we have stuffing photos, the packing certificate and the DG declaration match exactly, so the container is not held for re-inspection.

  3. Sea corridor

    No chokepoint, but North Pacific storms

    The drawn corridor from Shenzhen 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

    The carrier's AMS manifest is due 24 hours before loading

    Besides the importer's ISF, CBP must receive the carrier's electronic cargo declaration through AMS 24 hours before the container is laden in Shenzhen (19 CFR 4.7). CBP does not issue the permit to unlade at Pittsburg until it has that declaration, and late, incomplete or inaccurate cargo data can delay or deny it.

    What Anxin does: We give the carrier or NVOCC the final cargo description, HS code, UN number and package count before the documentation cut-off in Shenzhen, so the AMS filing and the DG manifest say the same thing.

  5. Import country

    California's battery-embedded product rules since January 2026

    Under California SB 1215, consumers have paid a recycling fee on covered battery-embedded products since 1 January 2026, and those products must be labelled with the maker's name or brand and the battery chemistry, or give that information on the maker's website. Manufacturers must also list covered and exempt products in an annual notice to retailers and CalRecycle.

    What Anxin does: If the goods landing at Pittsburg 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

    Demurrage and detention invoices must follow FMC rules

    Battery containers held for DG checks or paperwork can run up demurrage and detention at Pittsburg. Under the FMC's billing rule, in force since May 2024, carriers and terminals must invoice within 30 days with accurate, complete information, or the charge is not payable, and the billed party has at least 30 days to ask for a waiver or refund. A 2025 court ruling set aside only the section on who may be billed.

    What Anxin does: We keep the dates of discharge, availability and any DG hold for each container, so the importer can check invoices against them and dispute charges inside the FMC time limits.

Documents & compliance

Checklist for Shenzhen → Pittsburg

These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.

In Shenzhen, before the box is loaded

  • Confirmation from the carrier of the DG cut-off at Yantian or Shekou, rechecked in typhoon weeks
  • Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
  • Container packing certificate signed by a certified packing inspector after supervised stuffing
  • 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)

For the shipping line

  • Stuffing photos before, during and after packing, checked for blocking and bracing
  • Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
  • SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label

At the United States end

  • HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
  • Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request

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 Shenzhen 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

Common questions on the Shenzhen → Pittsburg route

Yes, if the container moves on a public highway. The IMDG waiver in 49 CFR 171.25(d)(2) only covers cargo that stays on the ship or moves between vessels; otherwise 49 CFR 172.604 requires a monitored number answered by someone with the emergency information. Goods shipped as 'Battery powered equipment' are exempt.

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.

Yes, provided a certified packing inspector supervises the stuffing and signs the container packing certificate. Since May 2026 Yantian and Dongguan MSA have also piloted joint factory inspection so the container can be loaded at Yantian without reopening; we check whether your shipment can use it.
