From Tianjin to Tampa, cargo moves from North China through Tianjin Xingang, crosses a Pacific crossing and a Panama Canal transit, and is discharged at the port of Tampa.

The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. This page sets out 6 points specific to this route, how Anxin handles each one and which documents to prepare.

What we need to start

  • Bohai Bay winter ice
  • Tianjin Xingang export

Route profile

What sets Tianjin → Tampa apart

Origin port

Tianjin (Xingang)

North China's main container gateway, where Tianjin Customs lets DG containers be inspected at the factory and loaded on arrival within a booked port slot, and where the Bohai Bay freezes at its edges in mid-winter.

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

6 points to plan for on the Tianjin → Tampa route

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

  1. Origin port

    Packaging appraisal comes first, even with Tianjin's quicker release

    China requires use appraisal of export dangerous-goods packaging before the goods may be exported. Tianjin port's 2025 facilitation measures shortened packaging appraisal time for lithium battery exports through quick release, and Tianjin Port Group provides port services for lithium DG containers, but the appraisal certificate is still a precondition for the rest of the filing.

    What Anxin does: We check at quotation that the packaging maker has its performance appraisal and apply for the use appraisal as soon as the packing is fixed, so the certificate is in hand before the MSA filing.

  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

    North Pacific winter storms before the canal

    NOAA's Ocean Prediction Center has recorded hurricane-force North Pacific storms in every month from October to April, most often in December. The Pacific leg to Panama crosses that ocean.

    What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing.

  4. Import country

    ISF closes 24 hours before loading in Tianjin

    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 Tianjin, ahead of the vessel's loading window.

  5. Import country

    Unentered battery containers go to General Order after 15 days

    A container landed at Tampa without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.

    What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Tampa, and chase any missing invoice or HTS detail while the ship is still at sea.

  6. Import country

    CPSC certificate data now filed at entry

    Since 8 July 2026, importers of consumer products that are subject to a CPSC certification requirement must electronically file the certificate data at entry; goods entered from a Foreign Trade Zone follow on 8 January 2027. Whether a battery-powered product is caught depends on the rules that apply to that product, not on the battery alone.

    What Anxin does: We ask whether the goods are consumer products that need a CPSC certificate and, if so, who files it, so that the question is settled before the goods arrive.

Documents & compliance

What to have ready: Tianjin to Tampa

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 Tianjin

  • Stuffing date, port-entry slot and DG cut-off at Tianjin agreed in that order
  • Packaging use-appraisal certificate issued before the MSA cargo report is filed
  • '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
  • Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)

For the carrier and the voyage

  • Canal routing and any canal-related surcharge confirmed for the booked vessel
  • SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
  • UN 38.3 test summary for every cell and battery type

For the importer in United States

  • ISF filer named; stuffing location and consolidator sent right after packing
  • Importer of record and the licensed customs broker who will file the entry
  • HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)

Before you book

One consistent file

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Tianjin export filings, the carrier booking and the United States import papers. We compare all three before confirming space.

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

Tianjin → Tampa: questions we are asked

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.

It can. In September 2026 the Panama Canal Authority postponed a planned draft cut in the Neopanamax locks because of Gatun Lake levels (advisory A-33-2026). We check the advisory in force when quoting.

Tianjin Customs offers a 'supervised factory loading, direct loading on port arrival' model: stuffing is supervised at the factory, the box enters the port in a booked slot and is loaded directly. Whether a given shipment can use it depends on the customs arrangement for the exporter and the port slot; we check both when you book.
