Hi Giovanni,

Sending a parcel from Shanghai to the UK via China Post is a common and cost-effective method. Here is a detailed breakdown of the pricing and process for your parcel (400x250x250mm, 2.5kg).

1. Calculating the "Volumetric Weight"
This is the most important step for China Post and most postal services. They charge based on whichever is greater: the actual weight or the volumetric weight.

Formula: (Length x Width x Height in cm) / 5000 (This is the standard divisor for China Post)

Your Parcel: 40cm x 25cm x 25cm = 25,000 cubic cm

Volumetric Weight: 25,000 / 5,000 = 5.0 kg

Even though your parcel weighs only 2.5kg, China Post will charge you based on the volumetric weight of 5.0kg. This is a crucial point.

2. Service Options & Estimated Prices (for 5.0kg)
China Post offers several services, with varying prices and delivery times.

Service Estimated Price (RMB) Estimated Delivery Time Key Features & Best For
Surface Mail (经济类) ¥250 - ¥350 60-90 days (very slow) Cheapest option. No tracking. For non-urgent, low-value items.
Air Mail (空运水陆路) ¥350 - ¥450 30-50 days Faster than surface, slower than air. Limited tracking. Good balance of cost/speed.
Air Parcel Post (航空小包) ¥450 - ¥550 15-30 days Standard air service. Has tracking to destination. Most common choice.
EMS (特快专递) ¥650 - ¥800+ 7-15 days Fastest and most expensive. Prioritized handling, full tracking, and faster customs.
Important Note: These are estimates. The final price can vary slightly based on the exact destination in the UK, the specific China Post office you use, and the declared value of your items (for insurance).

3. How to Get the Exact Price & Send Your Parcel
Repack (If Possible): Since you are being charged for 5kg, see if you can make the box smaller. A smaller box will lower the volumetric weight and the cost.

Visit a China Post Office: This is the best way to get an exact quote. Take your packaged item to your local post office in Shang



4. Important Things to Know Before You Go
Customs Declaration Form (CN23): You must fill out a customs form. You will need to:

List each item inside the parcel.

Declare the value of each item in USD or GBP.

Describe the items accurately (e.g., "Men's Cotton T-Shirt", "Plastic Toy Model").

Prohibited/Restricted Items: Do not send batteries, power banks, liquids, perfumes, aerosols, sharp objects, or any counterfeit goods. Check the full list on the China Post website.

Insurance: For valuable items, consider paying extra for insurance. The standard compensation for loss is limited.

Tracking: Air Parcel Post and EMS provide tracking numbers that can be used on the Royal Mail website once the parcel arrives in the UK.

Summary for Your Parcel:
Chargeable Weight: 5.0 kg (due to volumetric weight).

Recommended Service: Air Parcel Post (航空小包) for a good balance of speed and cost. Expect to pay around ¥500 RMB.

Next Step: Visit your local post office with your packed box for the final, exact price and to send it.
