From Shanghai to Vallejo, cargo moves through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules, crosses a North Pacific corridor with no canal or chokepoint, and is discharged at the port of Vallejo.

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 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.

What we need to start

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

Route profile

The Shanghai → Vallejo route in brief

Origin port

Shanghai (Yangshan / Waigaoqiao)

Yangshan and Waigaoqiao exports under Shanghai MSA's photo-verified packing system, where a mismatch between photos and EDI data keeps a DG box off the ship.

Sea corridor

Transpacific (North Pacific)

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

Where this route gets difficult

What to watch between Shanghai and Vallejo: 5 points

Listed from loading in Shanghai to import into United States, each with what we do about it.

  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

    No chokepoint, but North Pacific storms

    The drawn corridor from Shanghai 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.

  3. Import country

    ISF closes 24 hours before loading in Shanghai

    The Importer Security Filing must reach CBP no later than 24 hours before the container is laden aboard the vessel abroad. CBP's liquidated damages guidelines provide for a claim per violation for late, inaccurate or incomplete filings. Two of the data elements, the container stuffing location and the consolidator, only exist once the box is packed.

    What Anxin does: We send the importer's ISF filer the stuffing location, consolidator and manufacturer details as soon as the container is packed in Shanghai, ahead of the vessel's loading window.

  4. 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 Vallejo 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.

  5. Import country

    Product defects must be reported to CPSC within 24 hours

    US importers, like manufacturers and retailers, must tell CPSC within 24 hours once they have information reasonably suggesting that a consumer product fails a safety rule or has a defect that could create a substantial hazard. Battery overheating reports from customers can trigger that duty, and CPSC expects any investigation to take no more than about 10 working days.

    What Anxin does: We keep the manufacturer's batch records, UN 38.3 summaries and packing photos for each shipment to Vallejo, so the importer can answer CPSC questions quickly.

Documents & compliance

Documents to line up for Shanghai → Vallejo

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.

Before loading in Shanghai

  • 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
  • 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

For the carrier and the voyage

  • Stuffing photos before, during and after packing, checked for blocking and bracing
  • Lithium battery mark (SP188 cargo) or class 9 labels and placards
  • Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)

At the United States end

  • ISF filer named; stuffing location and consolidator sent right after packing
  • 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

Match the details first

We line up UN numbers, model names and package counts across the Shanghai filings, the booking with the carrier and the documents for United States before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Vallejo.

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

Shanghai → Vallejo: questions we are asked

Yes. Under 49 CFR 171.25(b)(3), SP188 packages of UN3480 or UN3090 need the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so do packages of batteries packed with or contained in equipment above 5 kg net. We check for it on carton photos before stuffing.

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.
