China Train and Flight Luggage: Limits and Packing Guide

Check the railway’s weight and size limits

The current 12306 carry-on luggage FAQ says that travelers are responsible for their own carried items and must place them without affecting shared space or safety. For ordinary passenger planning, its published limits are:

The FAQ’s wording applies the lower size limit to EMU trains. Do not assume that an airline-sized checked suitcase is accepted on a high-speed train simply because its weight is under 20 kg. If the item is near a limit, confirm the operator’s interpretation and the train arrangements before travel instead of relying on a suitcase’s marketing label.

A folding stroller used by an accompanying infant, and a qualifying folding wheelchair described in the FAQ for travelers who depend on assistance equipment, are allowed free outside the stated allowance. Confirm the particular item and assistance needed; this exemption does not remove the need to keep doors and shared spaces clear.

The official source describes charges and handling for oversized or overweight items, but paying an excess charge should not be treated as advance permission to bring any object aboard. Restricted or dangerous items have separate rules. If a bag cannot be carried or stowed safely, arrange an approved alternative before station day.

Rail security is a separate check from bag size

Use the railway prohibited and restricted item directory linked by 12306 for the object you plan to carry. Its current published directory took effect on 1 July 2022 and replaced the preceding list. An older FAQ summary should not override this item-by-item source.

For power banks and lithium batteries, that directory specifies clear markings and no more than 100 Wh rated energy per unit, with the stated exception for lithium-battery powered electric wheelchairs. Read the product’s energy marking rather than treating a number in mAh alone as proof of compliance. For a device with unclear markings, ask the railway before packing it.

The directory distinguishes different toiletries. For example, certain flammable non-pressurized perfumes, sprays and gels have a container-volume limit of 100 ml and one of each type; specified self-spraying pressurized products have separate 150 ml per-container and cumulative limits. These are category rules, not a blanket rule that every liquid on a train must fit a 100 ml bottle.

Do not pack camping fuel, a kitchen knife or an unfamiliar tool on the assumption that it is acceptable because you once flew with it in checked luggage. Some items cannot be carried, some may be consigned under the railway’s rules, and some are prohibited altogether. Confirm any permitted consignment service separately; putting a restricted object in a locked suitcase does not change its status.

For flights, check the actual airline and fare

There is no single baggage allowance in this guide for all flights within China. The operating airline, fare, route and booking conditions determine the ordinary allowance and charges. Check cabin-bag number, size and weight separately from checked-bag allowance. A paid ticket can have a different included allowance from another ticket on the same route.

Before buying, open the baggage conditions for the flight you will actually take. For a connection or codeshare, identify the operating carriers and ask how baggage allowance and through-checking apply to the complete ticket. Separate tickets may require collecting and rechecking bags; do not assume a suitcase will be transferred automatically.

Review airport and airline security information for liquids, medicines, batteries, camera equipment and any special item. A train permission does not establish flight permission. If medicine or mobility equipment needs advance approval, contact the airline with the specific equipment or product details while the booking can still be changed.

Weigh and measure the packed bag rather than its empty shell. Record the smallest applicable allowance across your journey and any bag you must pay for. A cheaper flight can stop being the better choice once its baggage cost, airport transfers and collection time are included.

Check power-bank markings before a domestic flight

CAAC’s notice published on 26 June 2025 prohibits power banks without a 3C mark, with an unclear 3C mark, or belonging to recalled models or batches on domestic flights from 28 June 2025. Check both the actual product marking and whether its model or batch is recalled. A brand name alone does not establish compliance.

This notice is about domestic flights. Do not extend its wording to every international route without checking the departure airport and operating airline’s current instructions. If your trip includes an international arrival and a later flight within China, that domestic leg needs its own check even if the power bank was accepted on the inbound flight.

CAAC’s published power-bank rules also prohibit power banks in checked baggage and their use during flight. Keep an allowed power bank in the permitted cabin arrangement and follow current carrier and crew instructions. Verify the current capacity, number and storage conditions with the airline rather than relying on an old travel-blog table.

For a suitcase that may be checked at the gate, take the power bank out before handing the bag over and follow staff instructions. Do not hide an unmarked or recalled item in checked luggage. If your power bank is not compliant, resolve that before the airport visit; a security checkpoint is not a reliable place to arrange a replacement, storage or shipping service.

Plan how the bags move between services

On a rail day, you move the bags through the entrance, security, waiting area, boarding gate, platform, carriage and arrival exit. Pack the passport and ticket information where you can reach them without opening the suitcase. Keep valuables, necessary medicines and a small set of essentials close to you.

Follow staff instructions for the available luggage racks or storage area. A free allowance does not reserve a particular storage space. Keep aisles, doors and seats clear, and choose a bag you can handle without relying on another passenger to lift it. If you need assistance with a mobility device, arrange the specific support ahead of time.

For the hotel transfer, compare the actual walk and changes rather than only the metro fare. A direct route can be practical with a light bag; several changes, a long final walk or a stroller can justify a prearranged vehicle. Confirm the pickup location and enough space for passengers and equipment. The airport-transfer guide can help with the arrival sequence.

Ask the hotel about storage hours, collection timing, identification requirements and any fee before planning a sightseeing day around its luggage room. For a courtyard, old-town or hillside stay, ask where a vehicle can stop and what carrying remains. A beautiful address on a map does not tell you whether a rolling suitcase can reach the entrance.

Make a packing check for each leg

As a hypothetical planning example, imagine a suitcase that fits your international flight allowance but exceeds the size rule quoted for your next high-speed train. The first flight’s acceptance does not settle the train leg. Before buying that rail ticket, confirm the railway arrangements or change the luggage plan. If the route also includes a village stay with a long final walk, packing less solves a second problem at the same time.

Keep a compact record of each operator’s answer and the date checked. Recheck when a flight, train, fare or piece of equipment changes. The goal is a bag you can use throughout the journey, with essential items accessible and a clear plan for every handover.
