What is the Import Customs Clearance Procedure? An Expert Explains the Overall Flow, Required Documents, and Pitfalls for Beginners

When importing goods from overseas to sell in Japan, you must go through "import customs clearance" without fail.

Many beginners may feel anxious, thinking, "The procedures seem difficult," "What documents are needed?" or "What should I do if my cargo gets stuck at customs?"

In this article, for those in charge of import operations for the first time and for e-commerce business operators, I will explain the overall flow of import customs clearance, essential documents, and common pitfalls and countermeasures that beginners often fall into in practice in an easy-to-understand manner.

1. The "Three Essential Documents" Required for Import Customs Clearance

To proceed with import customs clearance smoothly, preparing accurate documents is essential. First, let's grasp the three basic and important documents.

• Invoice (Commercial Invoice)

  • Role: A detailed statement and bill for the goods. It is the most important document for customs clearance, proving who sold what to whom and at what price.

• Packing List

  • Role: A document stating the number of items, weight (gross weight/net weight), and packaging dimensions of the cargo. The contents must match the invoice.

• B/L (Bill of Lading) or AWB (Air Waybill)

  • Role: A cargo claim ticket and transport contract issued by the shipping company. B/L is used for sea freight, and AWB is used for air freight.

2. The "Four Steps" from Cargo Arrival to Clearance

The general flow from the arrival of a ship or aircraft in Japan until you can pick up the cargo is as follows.

Step 1: Arrival of Cargo and Entry into Bonded Area

When a ship or aircraft arrives at a Japanese port or airport, the cargo is temporarily stored in a warehouse called a "bonded area" (a special area where taxes are not yet applied).

Step 2: Execution of Import Declaration

Based on the necessary documents such as the invoice, an import declaration is made to customs using NACCS (Nippon Automated Cargo and Port Consolidated System). In many cases, this task is entrusted to a professional customs broker.

Step 3: Examination and Inspection by Customs

Customs examines the submitted documents. If there are suspicious points or items to confirm, or through random selection, a "customs inspection" is conducted where the actual cargo is opened and checked.

Step 4: Payment of Customs Duty and Consumption Tax, and Import Permission

Calculate and pay the correct customs duty and domestic consumption tax. Once payment is confirmed, "import permission" is granted by customs, and you can then pick up the cargo for domestic use.

3. Pitfalls for Beginners! "Three Traps" Often Pointed Out by Customs

In practice, I have summarized the points that are checked particularly strictly by AI screening and customs officials, and where cargo is most likely to be held up.

1. The "price" on the invoice is inaccurate or ambiguous

• Pitfall: If you declare it as "$0" or just "No Commercial Value" because it is a sample, customs will stop it and ask you to "prove the actual value (appraised value)."

• Countermeasure: Even for samples, be sure to state an amount based on actual manufacturing costs or market value (e.g., Value for Customs Purpose Only: $50, etc.).

2. Insufficient confirmation of "other laws and regulations" such as the Food Sanitation Act and the Plant Protection Act

• Pitfall: Items that conflict with Japanese domestic laws (Food Sanitation Act, Plant Protection Act, Pharmaceuticals and Medical Devices Act, etc.), not just the Customs Act, cannot be cleared without prior permission or notification.

• Countermeasure: Especially when importing "items that come into contact with the mouth (tableware, water bottles, toys for infants)" or "cosmetics/supplements," be sure to consult with the relevant government agencies or a customs broker before purchasing.

3. Mistakes in selecting the correct "HS Code (commodity classification)"

• Pitfall: The tariff rate (HS code) changes depending on "what the product is made of" and "what its purpose is." If you get this wrong, you may be subject to penalties (additional tax) for under-declaration.

• Countermeasure: Clarify the material and purpose (e.g., is it plastic or wood?) in advance. If you are unsure, it is safest to utilize the customs "Advance Classification Ruling System" or check with a professional customs broker.

Summary: Efficient customs clearance is all about preparation

The biggest trick to passing import customs clearance smoothly is to "clear up any document deficiencies or applicability of other laws before the cargo arrives in Japan."

Especially when importing for the first time or making large-scale purchases for e-commerce, choosing a reliable customs broker (forwarder) as a partner and sharing product information for a meeting in advance can prevent wasted time and the occurrence of storage fees.

With thorough preparation, let's proceed with safe and secure international trade and e-commerce business!
