Japan Post is one of the logistics service providers commonly used by cross-border e-commerce sellers in the Japanese market. When using Japan Post’s international parcel service, sellers need to understand and comply with the relevant size restrictions. This article will introduce the definition, restrictions and impact of Japan Post’s international parcel size on sellers to help sellers better utilize Japan Post’s logistics services.

First, you need to understand the definition of Japan Post’s international parcel size. Japan Post has established a series of size restrictions based on the International Mail Agreement. These restrictions mainly include the length, width, height and weight of the parcel. The specific size restrictions may vary depending on the mailing method, destination country and mail category. The following are some common size restrictions and related requirements:

Parcel length limit: Generally, the length limit of international parcels is no more than 1.5 meters on the longest side. Parcels exceeding this length may be considered oversized or non-standard and may be subject to additional restrictions and fees.

Parcel width and height restrictions: In addition to the length limit, there are also certain restrictions on the width and height of the parcel. The specific restrictions may vary depending on the mailing method and destination country. Sellers should carefully read the relevant information provided by Japan Post to ensure that the parcel meets the requirements.

Weight Limits for Packages: The weight limit for international packages is usually 30 kg. However, some shipping methods and destination countries may have stricter weight limits. Sellers should understand the specific weight limits and choose the appropriate shipping method according to their needs.

It is very important for sellers to understand and comply with the size limits for international packages issued by Japan Post. If a package exceeds the size limit, the following problems may occur:

Increased Shipping Costs: Packages that exceed the size limit may be considered oversized or non-standard, which usually results in additional shipping costs. Sellers may need to pay additional fees to cover the shipping costs.

Delayed Shipping Speed: Oversized or non-standard packages may require special handling or use a different shipping method, which may result in longer shipping times. Sellers should consider this and inform buyers within the estimated time frame.

Return or Refusal: If a package significantly exceeds the size limit, the post office may refuse to accept or return the package. This may result in shipping delays, losses, and inconvenience.

To avoid the above problems, sellers can take the following measures:

Accurate measurement and weighing: When preparing and weighing the package, ensure that the length, width, height and weight of the package are accurately measured and weighed. Use appropriate tools and equipment to ensure the accuracy of the measurement.

Choose the right packaging materials: Choose packaging materials that are lightweight but have sufficient protective properties to reduce the volume and weight of the package. Reasonable use of filling materials and protective layers to ensure the safety and integrity of the package.

Research mailing methods: Understand the different mailing methods and choose the one that best suits your products and destination countries. Different mailing methods may have different size and weight restrictions, which may also affect the shipping speed and cost.

In summary, understanding and complying with the Japan Post International Parcel Size Restrictions is an important consideration for cross-border e-commerce sellers when using Japan Post Logistics Services in the Japanese market. Sellers should understand the specific size restriction requirements and comply with relevant regulations during the package preparation and mailing process. By reasonably selecting packaging materials, accurately measuring and weighing packages, and choosing the right mailing method, sellers can increase the smooth delivery rate of packages and provide customers with a better shopping experience.
