From Shanghai to Stockton, cargo moves out of Shanghai, crosses a North Pacific corridor with no canal or chokepoint, and is discharged at the port of Stockton.

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. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.

What we need to start

  • Yangshan / Waigaoqiao export
  • Photo-verified packing certificate
  • ISF filer
  • Supply-chain tracing file
  • HTS code 8507.60

Route profile

How Shanghai → Stockton differs from other lanes

Sea corridor

Transpacific (North Pacific)

No canal or Red Sea passage, but a North Pacific crossing where winter storms have collapsed container stacks.

Import country

United States

From ISF and AMS in China to a monitored emergency number on the US truck leg, with Section 301 and UFLPA shaping what arrives.

Where this route gets difficult

5 pain points from Shanghai to Stockton

They run from the Shanghai terminal through the voyage to Stockton and the United States import file.

  1. Origin port

    Shanghai's photo-verified packing certificate

    At Shanghai the packing inspector must upload photos taken before, during and after stuffing through the MSA's remote system, with face recognition and phone location on, before the electronic packing certificate goes out by EDI. A container is not loaded if the photos are missing, uploaded late, taken outside the verified stuffing site, or do not match the EDI cargo data. Stuffing sites outside Shanghai must be registered with Shanghai MSA.

    What Anxin does: We confirm that the stuffing site (including factory sites in Jiangsu or Zhejiang) is registered for Shanghai's remote system, and we check the photo upload against the EDI data before the packing certificate is sent.

  2. Sea corridor

    Winter storms with hurricane-force winds

    NOAA's Ocean Prediction Center found hurricane-force winds (64 knots and above) in North Pacific mid-latitude storms in every month from October to April, peaking in December, with 15 to 23 such storms per season in its 2001–2004 records. They are not typhoons, so they do not follow the tropical calendar.

    What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing and confirm the full DG data are on the manifest.

  3. Import country

    UFLPA: lithium became a high-priority sector in August 2025

    DHS added lithium to the Uyghur Forced Labor Prevention Act high-priority sectors in August 2025. By then CBP had stopped more than 16,700 shipments for UFLPA examination. For battery importers the practical effect is that CBP can ask where cells, cathode and lithium compounds came from, and a shipment waits while the importer answers.

    What Anxin does: We tell the importer at quotation stage that supply-chain tracing may be requested, and keep manufacturer names and addresses consistent across invoice, packing list and ISF so the paper trail does not contradict itself.

  4. Import country

    SP188 packages need an extra US marking

    Small cells and batteries shipped under IMDG special provision 188 do not need a dangerous goods declaration at sea, but 49 CFR 171.25(b)(3) adds a US condition: each package of UN3480 or UN3090 must carry the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so must packages of batteries with or in equipment above 5 kg net. Cartons printed for other markets often lack it.

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

  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 Stockton 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.

Documents & compliance

Documents to line up for Shanghai → Stockton

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.

At the Shanghai end

  • Stuffing photos (before, during, after) uploaded to Shanghai MSA's remote system before the EDI packing certificate is sent
  • Stuffing site registered and geo-verified with Shanghai MSA; fire-safety proof for lithium DG warehouses
  • 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
  • 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

  • Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
  • 24-hour emergency response number (and provider reference) for the US road leg
  • Importer of record and the licensed customs broker who will file the entry

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 Shanghai 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 Shanghai to Stockton

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.

It can, but Shanghai MSA checks the phone location of the packing photos against a verified stuffing site, and sites outside Shanghai must be registered with it. We confirm registration before the stuffing date; otherwise the container can be refused for loading.
