Customs Clearance Procedures for International Mail: System Explanation
Interlink編集部Customs Clearance Procedures for International Postal Items
Customs clearance procedures for international postal items are the procedures through which Japan Customs checks mail items arriving in Japan from abroad. Customs verifies the contents, declared value, applicable duties and taxes, and whether the items are subject to import prohibitions or import restrictions.
These procedures may become relevant for personal imports, overseas e-commerce purchases, gifts, unaccompanied articles, samples, and small commercial shipments. Unlike ordinary ocean cargo, air cargo, or courier shipments, international postal items are handled through Japan Post, and customs checks are conducted through the postal clearance process.
For international postal items, the clearance process differs significantly depending on whether the taxable value is JPY 200,000 or less, or exceeds JPY 200,000. Postal items with a taxable value of JPY 200,000 or less are generally delivered after customs inspection or delivered together with a tax notice when duties and taxes are due. Postal items with a taxable value exceeding JPY 200,000 generally require an import declaration.
However, a taxable value of JPY 200,000 or less does not mean that the item will always be delivered without further checks. Additional documents may be required if the value, contents, intended use, or regulatory status of the item is unclear. If the item is subject to food, pharmaceutical, plant, animal, CITES, intellectual property, dangerous goods, or other import controls, customs clearance may be delayed or refused even when the value is low.
International postal items are sometimes misunderstood as simple mail that can be received easily. In practice, they may involve customs duties, consumption tax, import declarations, checks under other laws, postal prohibitions, air dangerous goods restrictions, intellectual property concerns, return shipment, destruction, or refusal of delivery.

Purpose and Background of the System
The customs clearance system for international postal items allows Customs to collect duties and consumption tax, prevent prohibited goods from entering Japan, verify restricted imports, and enforce intellectual property rights at the border.
As cross-border e-commerce and personal imports have grown, even small postal items increasingly raise issues similar to ordinary commercial cargo. Customs may need to check the price, origin, quantity, intended use, ingredients, materials, brand authenticity, and dangerous goods status of the item.
Postal handling requirements and import requirements are separate. An item may be accepted as mail in the country of origin, but that does not automatically mean that it can be imported into Japan. Conversely, an item that might be imported as ordinary cargo may still be unacceptable as international mail because of postal or air transport restrictions.
Main Situations Where the System Applies
| Situation | Examples | Main Customs Clearance Issues |
|---|---|---|
| Overseas e-commerce purchases | Clothing, shoes, bags, electronics, accessories, parts, hobby goods | Taxable value, simplified tariff rates, price documents, intellectual property checks, battery or dangerous goods classification |
| Gifts from overseas | Gifts from family or friends, food, clothing, souvenirs | Unknown value, unclear contents, exemption eligibility, food, plant, or animal quarantine checks |
| Corporate samples | Food samples, cosmetic samples, chemicals, parts, exhibition samples | Valuation of free samples, purpose explanation, compliance with other laws, distinction from commercial sales |
| Unaccompanied articles | Personal effects or purchased items sent separately from the traveler’s entry into Japan | Declaration at entry, duty exemption limits, personal use, commercial intent |
| High-value goods | Watches, jewelry, brand-name goods, machinery parts, professional equipment | Import declaration for goods exceeding JPY 200,000, price evidence, authenticity proof, insurance and postage details |
| Food, pharmaceuticals, and cosmetics | Supplements, health foods, medicines, cosmetics, medical devices | Food Sanitation Act, PMD Act, personal use versus commercial use, quantity, efficacy claims |
| Plants and animal-derived products | Seeds, seedlings, fruits, timber, meat products, dairy products, leather goods, feather products | Plant quarantine, animal quarantine, CITES, Invasive Alien Species Act, certificate requirements |
| Hazardous materials and batteries | Perfume, spray cans, paints, lithium batteries, mobile batteries | Postal acceptance, air dangerous goods restrictions, prohibited postal items, return shipment risk |
Basic Structure of the System
When an international postal item arrives in Japan, it is sent to a postal facility where customs inspection is conducted. Customs checks the contents, value, quantity, intended use, applicable taxes, and whether any import restrictions apply.
If the taxable value is JPY 200,000 or less, the item may be delivered after customs inspection. If duties or consumption tax are due, a Notice of Assessment for International Mail or payment slip may be issued, and the recipient pays the assessed amount before or upon receipt.
If the taxable value exceeds JPY 200,000, an import declaration is generally required. The addressee may receive guidance from Japan Post and must prepare documents such as invoices, receipts, order confirmations, payment records, product descriptions, and documents required under other laws where applicable.
Some postal items, such as certain gifts or items whose value cannot reasonably be identified by the addressee, may be handled differently. In practice, the correct response depends on the specific notice received. The recipient should read the notice carefully and avoid leaving the matter unresolved.
Application Process Flow
- The international postal item arrives in Japan.
- The item is sent to the postal facility where customs inspection is conducted.
- Customs checks the contents, value, quantity, intended use, taxes, and import restrictions.
- Customs determines whether the taxable value is JPY 200,000 or less, or exceeds JPY 200,000.
- If the taxable value is JPY 200,000 or less and no tax or additional check is required, the item proceeds to delivery.
- If duties or taxes are due, the recipient pays them based on the Notice of Assessment for International Mail or payment slip.
- If the contents, value, intended use, or regulatory status is unclear, Customs may issue a Notice of Customs Procedures for Mail Arriving from Abroad.
- If the taxable value exceeds JPY 200,000, an import declaration is generally required.
- If food, pharmaceuticals, plants, animal-derived products, CITES-listed goods, suspected IP-infringing goods, dangerous goods, or other regulated items are included, separate regulatory checks may be required.
- After the necessary documents are submitted, taxes are paid, and regulatory checks are completed, the item is delivered, released, returned, destroyed, or otherwise handled according to the result of the procedure.
Main Documents
| Document Name | Main Contents | Use Case | Practical Notes |
|---|---|---|---|
| Notice of Assessment for International Mail | Notice showing the assessed duties, taxes, payment details, and information about the postal item. | Used when the recipient receives a postal item subject to duties or taxes. | If the recipient has questions about the amount, item description, or taxable value, they should confirm the issue before accepting the item. |
| Payment Slip | Document used to pay customs duties, consumption tax, internal taxes, and related amounts. | Used when tax payment is required. | Payment may be made at delivery, at a designated post office, or through the method stated in the guidance. |
| Notice of Customs Procedures for Mail Arriving from Abroad | Notice requesting additional information or documents about contents, price, intended use, or compliance with other laws. | Used when Customs needs additional verification before clearance. | The response should identify the notice number, addressee, contact details, and supporting documents. If ignored, clearance will not proceed. |
| Invoice, Receipt, Order Confirmation | Documents showing purchase price, payment details, product name, quantity, postage, and related costs. | Used to verify taxable value. | Postage and insurance may affect taxable value, not only the product price. |
| Product Page, Catalog, Price List | Documents showing specifications, sales price, materials, ingredients, and intended use. | Used when contents or price are unclear. | Overseas e-commerce pages may disappear later, so saving the relevant page at the time of order is useful. |
| Payment Record | Credit card statement, PayPal record, bank transfer record, or other evidence of payment. | Used to explain payment amount and foreign currency purchase value. | The card company’s exchange rate and the exchange rate used by Customs may differ. |
| Declaration of Personal Effects and Unaccompanied Articles | Declaration made at entry into Japan when the traveler has unaccompanied articles. | Used when applying for duty exemption treatment for unaccompanied articles. | If the unaccompanied articles were not declared at entry, it may be difficult to claim the treatment later. |
| Permit, Approval, Certificate | Documents proving permits, approvals, inspections, or certifications under other laws. | Used for food, pharmaceuticals, cosmetics, plants, animals, CITES-listed goods, chemicals, and similar regulated items. | Even if duties and taxes are paid, the item may not be released until the required regulatory confirmation is completed. |
Eligibility Requirements and Items Typically Excluded
| Category | Applicable Items | Excluded or Often Handled Separately | Practical Confirmation Points |
|---|---|---|---|
| International postal item customs clearance | Postal items arriving in Japan from overseas and handled through Japan Post. | International courier shipments, air cargo, ocean cargo, and other non-postal transport modes. | Confirm the tracking number, notice type, and whether the shipment is actually handled as postal mail. |
| Postal items with taxable value of JPY 200,000 or less | Postal items whose taxable value is JPY 200,000 or less. | Split shipments that may need to be aggregated, such as multiple shipments from the same sender to the same recipient around the same time. | Check product price, postage, insurance, and whether the shipment has been split. |
| Postal items exceeding JPY 200,000 | Postal items whose taxable value exceeds JPY 200,000 and generally require an import declaration. | Categories that may be handled differently, such as certain gifts or items whose value cannot be determined by the addressee. | Review the guidance document and confirm whether an import declaration is required. |
| Simplified tariff rates | General imported goods and international postal items with a taxable value of JPY 200,000 or less that qualify for simplified tariff treatment. | Items for which simplified tariff rates are not appropriate, items excluded from the system, or cases where the consignee does not wish to use simplified rates. | Simplified tariff rates do not apply automatically to all goods valued at JPY 200,000 or less. |
| Unaccompanied articles | Personal effects declared as unaccompanied articles when the traveler enters Japan. | Items not declared at entry, items intended for sale or business use, or items addressed to a third party. | The duty-free allowance is assessed by combining accompanied personal effects and unaccompanied articles. |
| Items subject to other laws | Food, pharmaceuticals, cosmetics, plants, animal-derived products, chemicals, and intellectual property-related goods. | Items lacking required permits, approvals, inspections, or certificates. | Compliance with the competent authority’s requirements is separate from the customs tax assessment. |
| Postal prohibited items and air dangerous goods | Items that may be accepted for international mail under postal and aviation rules. | Dangerous goods not accepted by postal services, including explosives, gases, flammable liquids, corrosive substances, and radioactive materials. | An item that can be transported as ordinary cargo may still be prohibited as international mail. |
Differences Between Taxable Values of JPY 200,000 or Less and Over JPY 200,000
| Category | Customs Handling | Required Documents | Tax Payment Method | Customs Broker Involvement |
|---|---|---|---|---|
| Taxable value of JPY 200,000 or less | The item is delivered or assessed for duties and taxes based on the customs inspection result. | The postal declaration may be sufficient, but price evidence or content details may be requested. | Duties and taxes are paid at delivery or through the method stated in the notice. | The process usually proceeds through Japan Post, but additional customs confirmation may still be required. |
| Taxable value over JPY 200,000 | An import declaration is generally required. | Invoices, receipts, order confirmations, product descriptions, payment records, and regulatory documents may be required. | Duties and taxes are paid based on the import declaration. | The consignee, Japan Post, or a customs broker may be involved depending on the case. |
| Unknown price or contents | Customs may request additional verification before clearance. | Price evidence, product descriptions, intended use explanations, order history, catalogs, and payment records may be required. | The tax amount is determined after the documents are reviewed. | The recipient may need to consult Customs, Japan Post, a customs broker, or the competent authority. |
| Possible application of other laws | Delivery may be suspended until the relevant import regulation is confirmed. | Permits, approvals, notifications, certificates, or inspection records may be required. | Regulatory procedures are required in addition to payment of duties and taxes. | Specialized support from a customs broker or regulatory specialist may be necessary. |
Even when the taxable value is JPY 200,000 or less, additional checks may be required if the item is regulated, if the price is unclear, or if the contents cannot be identified. If the taxable value exceeds JPY 200,000, the item should not be treated as ordinary mail that will simply be delivered without an import declaration.
Positioning of Simplified Tariff Rates
Simplified tariff rates may apply to general imported goods and international postal items whose total taxable value is JPY 200,000 or less. The system simplifies duty calculation by applying broad tariff categories instead of detailed item-by-item classification in certain cases.
However, simplified tariff rates do not apply to every item. Some goods are excluded, and general tariff rates may apply where simplified treatment is not appropriate. If postal items are split into multiple shipments from the same sender to the same recipient around the same time, the values may be aggregated for assessment.
Whether simplified tariff rates apply depends on the item, value, shipment pattern, the recipient’s preference, and Customs’ assessment. It should not be assumed that every postal item valued at JPY 200,000 or less automatically qualifies for simplified tariff treatment.
Taxable Value and Foreign Currency Purchases
The taxable value of an international postal item is generally based on the item price plus postage, insurance, and other relevant costs. As a result, an item that appears to be below JPY 200,000 based only on the product price may exceed that threshold once shipping and insurance are included.
Overseas e-commerce sites often show prices in foreign currencies such as US dollars, euros, Chinese yuan, or Korean won. Customs converts the value into Japanese yen using the exchange rate applicable for customs purposes.
The exchange rate used by Customs may differ from the exchange rate used by a credit card company or payment service provider. This difference occurs because the applicable system, reference date, and exchange rate may not be the same.
In practice, the recipient should keep order confirmations, receipts, payment records, product pages, shipping charge details, insurance details, and documents showing the foreign currency amount.
If the Price or Contents Are Unclear
If the price, contents, intended use, or regulatory status of a postal item is unclear, the recipient may receive a Notice of Customs Procedures for Mail Arriving from Abroad.
When this notice is received, the recipient should check the inquiry details and submit supporting documents such as invoices, receipts, catalogs, product descriptions, order history, payment records, screenshots of product pages, and explanations of intended use.
If the documents are insufficient, Customs may determine the taxable value by referring to prices of similar goods. If the contents, ingredients, or intended use cannot be explained, checks under other laws may not be completed, and delivery may be delayed or refused.
The recipient should confirm the tracking number, notice number, storage location, submission deadline, and the exact information requested. Leaving the notice unanswered can result in return shipment or other disposal according to the applicable procedure.
Using International Mail for Unaccompanied Articles
When a traveler sends personal effects or items purchased overseas separately from their own entry into Japan by international mail, those items may be treated as unaccompanied articles.
To claim duty exemption treatment for unaccompanied articles, the traveler must declare them at entry into Japan using the Declaration of Personal Effects and Unaccompanied Articles and obtain confirmation from Customs.
The duty-free allowance is not calculated separately for accompanied personal effects and unaccompanied articles. They are combined when determining whether the traveler remains within the exemption limit.
| Item for Confirmation | Details | Points to Note | Potential Consequences if Issues Arise |
|---|---|---|---|
| Declaration at entry | The Declaration of Personal Effects and Unaccompanied Articles must state that unaccompanied articles exist. | If the items were not declared at entry, it may be difficult to claim unaccompanied article treatment later. | The items may be treated as ordinary imports and assessed accordingly. |
| Duty-free allowance | The allowance is assessed by combining accompanied personal effects and unaccompanied articles. | Unaccompanied articles do not have a separate duty-free allowance. | Amounts exceeding the allowance may be subject to duties and taxes. |
| Intended use | Confirm whether the items are for personal use, gifts, resale, or business use. | Items for resale or business use may not qualify as personal effects. | Ordinary import procedures and regulatory checks may be required. |
| Other regulations | Check whether food, plants, animal-derived products, pharmaceuticals, cosmetics, or similar regulated goods are included. | Unaccompanied articles are not exempt from import restrictions under other laws. | The item may be stopped, returned, destroyed, or refused if required certificates are missing. |
Relationship Between Postal-Specific Rules and General Cargo Rules
International postal items must satisfy both general import regulations and postal-specific restrictions. These two layers should not be confused.
| Category | Main Content | Relation to General Cargo | Practical Implication |
|---|---|---|---|
| Prohibitions and restrictions common to general cargo | Narcotics, IP-infringing goods, food, pharmaceuticals, plants, animals, CITES-listed goods, and similar restricted items. | International postal items are not exempt from ordinary import restrictions. | An item may be stopped by Customs or the competent authority even if it arrives by mail. |
| Postal prohibited items | Items prohibited under postal conventions, postal law, or Japan Post handling conditions. | Some goods that may be transported as ordinary cargo cannot be accepted as international mail. | The item may be refused as mail before customs clearance is completed. |
| Air dangerous goods | Spray cans, perfume, fireworks, flammable liquids, corrosive substances, lithium battery-related products, and similar goods. | Goods requiring dangerous goods packaging or declaration may be unacceptable as mail. | Even if accepted in the country of origin, the item may be returned during transport or after arrival in Japan. |
| Country or region-specific restrictions | Import prohibitions, quantity limits, and certificate requirements that differ by destination. | When sending from Japan to another country, the destination country’s rules must also be checked. | The same item may be acceptable for one country but prohibited or restricted for another. |
The fact that an item can be transported as ordinary cargo does not mean that it can be sent by international mail. The fact that an item was accepted as mail does not mean that it will be legally importable in Japan.
Comparison with Other Systems
| Comparison Item | International Postal Items | International Courier and Air Cargo | Ocean Cargo | Personal Effects and Unaccompanied Articles |
|---|---|---|---|---|
| Main handling parties | Japan Post and Customs are central to the postal clearance process. | Courier companies, airlines, customs brokers, and Customs are involved. | Shipping lines, NVOCCs, freight forwarders, customs brokers, warehouses, and Customs are involved. | The traveler and Customs are central, with later confirmation when unaccompanied articles arrive. |
| Declaration requirement | The process changes at the JPY 200,000 threshold; goods over that amount generally require import declaration. | Import declaration is usually handled as part of the courier or air cargo process. | Import declaration, cargo arrival, customs permission, and release are handled through the normal import process. | Declaration at entry is required when the traveler has unaccompanied articles. |
| Notification method | Notices may be issued through Japan Post, including assessment notices and customs procedure notices. | The courier company or customs broker may request documents from the importer. | The forwarder, customs broker, shipping line, or warehouse may contact the importer or consignee. | Confirmation begins at entry and continues when the unaccompanied articles arrive. |
| Price documentation | Order history, receipts, product pages, payment records, postage, and insurance details are important. | Commercial invoice, packing list, air waybill, payment records, and product details are used. | Commercial invoice, packing list, bill of lading, arrival notice, and related documents are used. | Purchase records, passport information, and the Declaration of Personal Effects and Unaccompanied Articles are relevant. |
| Other regulatory checks | Even small or personal-use items may require checks under food, pharmaceutical, plant, animal, CITES, or IP rules. | Regulatory checks are common, especially for commercial imports. | The importer, customs broker, and competent authority usually coordinate regulatory checks. | Personal use does not automatically remove restrictions on regulated goods. |
| Common misunderstanding | Recipients often assume that mail can be received without customs issues. | Importers may assume that the courier company handles every legal requirement automatically. | Importers may assume that the forwarder resolves every regulatory issue once cargo arrives. | Travelers may assume that all personal effects are duty-free. |
Postal Items Often Requiring Confirmation Under Other Laws
| Contents | Potentially Relevant Laws and Regulations | Documents to Confirm | Notes |
|---|---|---|---|
| Food, confectionery, seasonings, health foods | Food Sanitation Act, food labeling rules, PMD Act | Ingredient list, composition, intended use, sales purpose, quantity | Even personal-use items may require confirmation depending on quantity and purpose. |
| Pharmaceuticals, supplements, cosmetics, medical devices | Pharmaceuticals and Medical Devices Act (PMD Act) | Ingredients, efficacy claims, intended use, quantity, personal use or sale | Classification as a pharmaceutical, cosmetic, or medical device may affect whether the item can be imported. |
| Plants, seeds, fruits, timber | Plant Protection Act, CITES, Invasive Alien Species Act | Scientific name, country of origin, phytosanitary certificate, CITES permit | Quarantine or certificates may be required even for small quantities. |
| Meat products, dairy products, animal-derived products | Livestock Infectious Diseases Prevention Act, Food Sanitation Act, CITES | Ingredients, processing method, sanitary certificate, intended use | Souvenirs and gifts may be stopped by animal quarantine. |
| Brand-name goods and character merchandise | Intellectual property laws, Customs Act | Proof of authenticity, purchase record, license, supplier information | If the item is suspected to be counterfeit or infringing, release may be refused. |
| Chemicals, reagents, liquids, powders | Poisonous and Deleterious Substances Control Act, Chemical Substances Control Act, Industrial Safety and Health Act, air dangerous goods rules | SDS, composition, CAS number, intended use, dangerous goods classification | Samples and research materials may still be stopped if composition cannot be confirmed. |
| Electronic devices and batteries | Air dangerous goods rules, PSE requirements, Radio Act, and related rules | Lithium battery status, specifications, capacity, intended use, sales purpose | Mobile batteries and standalone batteries may be prohibited as international mail. |
Common Misconceptions
| Common Misconception | Correct Understanding | Practical Note |
|---|---|---|
| Because it is mail, customs procedures rarely cause problems. | International mail is still imported cargo and is subject to customs inspection. | Keep records explaining value, contents, intended use, and regulatory status. |
| If the value is JPY 200,000 or less, the item will always be delivered. | Even low-value postal items may require tax payment, price verification, regulatory checks, or prohibited item confirmation. | Check any notice from Japan Post or Customs immediately. |
| Only the product price matters for the JPY 200,000 threshold. | Postage, insurance, and related costs may affect the taxable value. | Check the total amount, not only the product price shown on the shopping page. |
| Free samples do not require tax or regulatory checks. | Free samples may still have a customs value and may be subject to other laws. | Prepare documents explaining the no-charge reason, commercial value, intended use, ingredients, and quantity. |
| Personal use means food, medicines, or cosmetics can be received freely. | Personal use does not automatically remove food, pharmaceutical, plant, animal, or other import restrictions. | Check quantity, intended use, ingredients, efficacy claims, and certificate requirements. |
| Unaccompanied articles have a separate duty-free allowance. | Accompanied personal effects and unaccompanied articles are combined when applying the duty-free allowance. | The Declaration of Personal Effects and Unaccompanied Articles should be completed at entry. |
| If it was accepted as mail overseas, it can be received in Japan. | Postal acceptance and import eligibility in Japan are separate issues. | Check postal prohibitions, air dangerous goods rules, customs restrictions, and other laws separately. |
| Paying taxes guarantees that the item will be released. | Taxes are only one part of the process. Prohibited goods, restricted goods, IP concerns, and dangerous goods issues may still prevent release. | Confirm whether the contents can legally be imported, not only whether taxes are payable. |
Decision Checklist
| Situation | Contact Party | Items to Confirm | Action if Issues Arise |
|---|---|---|---|
| The postal item is shown as being under customs processing. | Japan Post, Customs Mail Branch | Tracking number, storage location, notice status, customs inquiry status. | Check whether a customs procedure notice has been issued and prepare the requested documents. |
| A Notice of Assessment for International Mail is received. | Japan Post, Customs | Tax amount, item description, taxable value, payment method, delivery method. | If the amount or classification appears unclear, confirm with Customs before accepting the item. |
| A notice concerning goods over JPY 200,000 is received. | Japan Post, customs broker, Customs | Import declaration requirement, price documents, product description, other regulatory requirements. | Confirm the declaration method and responsible party instead of leaving the notice unanswered. |
| Price documents are insufficient. | Supplier, sender, importer, Customs | Order history, receipt, payment record, product page, postage, insurance. | Collect available evidence and explain the basis of the declared value. |
| Food, pharmaceuticals, or cosmetics are included. | Importer, competent authority, customs broker, Customs | Ingredients, intended use, quantity, sales purpose, personal use status. | Check the Food Sanitation Act, PMD Act, and related requirements before assuming the item can be released. |
| Plants or animal-derived products are included. | Importer, quarantine authority, Customs, sender | Scientific name, country of origin, processing status, certificates, CITES applicability. | Confirm quarantine requirements and import eligibility. If prohibited, return or destruction may be necessary. |
| Hazardous materials or batteries are included. | Sender, Japan Post, importer | Product name, ingredients, SDS, lithium battery status, dangerous goods classification. | Confirm whether international mail can be used. If not, consider ordinary cargo arrangements. |
| Brand-name or character goods are detained. | Supplier, importer, Customs | Proof of authenticity, purchase record, supplier information, license, transaction history. | Submit evidence addressing intellectual property concerns and confirm whether release is possible. |
Typical Situations Where the System Causes Issues
| Case | Reason for Issue | Required Documentation | Practical Response |
|---|---|---|---|
| Overseas e-commerce goods slightly exceed JPY 200,000. | The taxable value may exceed JPY 200,000 when postage and insurance are added to the product price. | Order confirmation, receipt, shipping cost details, insurance details, payment record. | Follow the guidance for goods exceeding JPY 200,000 and confirm whether an import declaration is required. |
| Insufficient price documents lead to higher-than-expected taxation. | If Customs cannot verify the price, it may refer to prices of similar goods. | Product page, sale price evidence, order history, payment record, explanation from the sender. | Submit additional documents supporting the declared value. |
| The duty-free allowance for unaccompanied articles is misunderstood. | Accompanied personal effects and unaccompanied articles must be combined when applying the allowance. | Declaration of Personal Effects and Unaccompanied Articles, purchase records, passport information, arrival notice. | Confirm whether the articles were declared at entry and assess the allowance on a combined basis. |
| Mobile batteries or perfume are sent by international mail. | These items may be prohibited as postal items or restricted as air dangerous goods. | Product name, ingredient list, SDS, battery specifications, capacity, packaging details. | Confirm postal acceptance. If mail cannot be used, consider ordinary cargo or another lawful transport method. |
| A customs procedure notice is ignored. | Without a response or documents, clearance cannot proceed and the item may be returned after the storage period. | Notice, tracking number, notice reference, inquiry details, submission deadline. | Review the notice and submit the required documents promptly. |
| Samples require checks under other laws. | Free samples may still be regulated if they include food, cosmetics, medical devices, plants, or chemicals. | No-charge explanation, intended use, ingredient list, SDS, quantity, sales plan. | Confirm whether permits, filings, certificates, or inspections are required. |
| Goods are described as personal use but the quantity is large. | The quantity or import frequency may suggest resale, business use, or commercial import. | Purpose explanation, quantity basis, purchase history, sales plan, past import record. | Explain the basis for personal use. If commercial use is indicated, prepare for ordinary import procedures. |
| Food, meat products, or plants sent by mail are held. | Food sanitation, animal quarantine, plant quarantine, or CITES checks may be required. | Ingredient list, processing method, scientific name, country of origin, inspection certificate, CITES permit. | Confirm import eligibility. If required certificates are missing, return or destruction may result. |
| Brand-name goods are detained for suspected IP infringement. | Customs may inspect goods suspected of being counterfeit or infringing. | Proof of authenticity, purchase record, supplier information, license, transaction history. | If authenticity cannot be shown, release may be refused. |
Practical Scenarios
Scenario 1: Unaccompanied Articles Sent by International Mail
A traveler may purchase goods overseas and send them to Japan by international mail after returning home. In that case, the items may be treated as unaccompanied articles only if they were properly declared at entry using the Declaration of Personal Effects and Unaccompanied Articles.
The important point is that the duty-free allowance is assessed by combining accompanied personal effects and unaccompanied articles. If the traveler did not declare the unaccompanied articles at entry, or if the items are for resale or business use, the goods may be handled as ordinary imports instead.
Scenario 2: Price or Contents Are Unclear
When Customs cannot identify the value, contents, intended use, or regulatory status of the item, the recipient may receive a Notice of Customs Procedures for Mail Arriving from Abroad. This notice should not be ignored.
The recipient should prepare invoices, receipts, order confirmations, product pages, payment records, catalog information, and explanations of intended use. If Customs cannot verify the value from the documents, it may determine the taxable value by referring to similar goods.
Scenario 3: Foreign Currency Purchases
Many overseas e-commerce purchases are paid in foreign currency. The amount charged by the card company may differ from the customs value calculated by Customs, because the applicable exchange rate and reference date may differ.
For that reason, the recipient should keep documents showing the foreign currency amount, product price, postage, insurance, payment date, and order details. These documents help explain how the taxable value should be understood.
Scenario 4: Simplified Tariff Rate
For international postal items with a taxable value of JPY 200,000 or less, simplified tariff rates may apply. This does not mean that every low-value postal item automatically qualifies for simplified treatment.
Some goods are excluded, and general tariff rates may apply depending on the item, shipment pattern, recipient’s request, or Customs’ assessment. Split shipments from the same sender to the same recipient around the same time may also be aggregated.
Practical Points for Freight Forwarders and Customs Brokers
International postal items are processed through Japan Post, so freight forwarders and customs brokers do not always control the shipment from the beginning as they would for ordinary ocean or air cargo.
Nevertheless, importers and companies may consult freight forwarders or customs brokers when a postal item is stopped, taxed, or subject to regulatory checks. In such cases, the practical role is to organize the facts, identify missing documents, and clarify which authority or party should be contacted.
| Check Item | Details to Confirm | Supportable Actions | Matters That Should Not Be Concluded Without Confirmation |
|---|---|---|---|
| Location of the postal item | Whether the item is at a postal customs facility, awaiting delivery, under customs inquiry, or in the return process. | Help the importer organize the tracking number, notice, and current status. | Do not assume that the item can be directly moved or released outside the postal process. |
| Type of notice | Whether the notice is a tax assessment notice, customs procedure notice, or guidance for goods exceeding JPY 200,000. | Identify the next procedural step and the documents likely required. | Do not treat all notices as ordinary tax notices. |
| Description of contents | Product name, quantity, material, ingredients, intended use, sales purpose. | Help structure a clear explanation for Customs. | Do not create a declaration based on assumptions where the actual contents are unknown. |
| Price documentation | Invoice, receipt, order history, product page, payment record, postage, insurance. | Help organize supporting documents for the taxable value. | Do not explain a value inconsistent with the actual transaction. |
| Other regulatory checks | Food, PMD Act, plant quarantine, animal quarantine, CITES, IP, chemicals, dangerous goods. | Identify possible applicable regulations and recommend confirmation with the competent authority. | Do not state that no permit or certificate is required without checking the item details. |
| Import declaration | Whether the item exceeds JPY 200,000 or is commercial cargo requiring declaration. | Help assess whether customs broker involvement is necessary. | Do not assume that a postal item can freely be converted into ordinary cargo. |
Practical Points to Note
- Confirm whether the taxable value is JPY 200,000 or less, or exceeds JPY 200,000.
- Even if the taxable value is JPY 200,000 or less, additional checks may be required when the price, contents, or regulatory status is unclear.
- Check not only the product price but also postage, insurance, and split shipment issues.
- Keep order history, receipts, product pages, payment records, and shipping charge details.
- If a Notice of Customs Procedures for Mail Arriving from Abroad is received, review it promptly and respond within the required period.
- For foreign currency purchases, the card company’s exchange rate may differ from the exchange rate used for customs valuation.
- For unaccompanied articles, the Declaration of Personal Effects and Unaccompanied Articles should be completed at entry.
- The duty-free allowance for unaccompanied articles is assessed together with accompanied personal effects.
- Food, pharmaceuticals, cosmetics, plants, animal-derived products, chemicals, and similar items may require checks under other laws.
- International mail requires both ordinary import restriction checks and postal-specific prohibited item or air dangerous goods checks.
- If there is a question about the tax amount or item classification, confirm with Customs before accepting delivery.
- If the postal item is damaged or does not arrive, contact the post office and keep the packaging and contents.
- Prohibited or regulated items may be returned, destroyed, confiscated, or otherwise disposed of according to the applicable procedure.
Summary
Customs clearance procedures for international postal items are the procedures through which Customs checks mail items arriving in Japan from abroad. Customs verifies the contents, value, duties and taxes, and whether import restrictions apply.
The process differs depending on whether the taxable value is JPY 200,000 or less, or exceeds JPY 200,000. Postal items with a taxable value of JPY 200,000 or less may be delivered after inspection or delivered with a Notice of Assessment for International Mail when duties and taxes are due. Postal items exceeding JPY 200,000 generally require an import declaration.
If the price, contents, intended use, or regulatory status is unclear, the recipient may receive a Notice of Customs Procedures for Mail Arriving from Abroad. In that case, invoices, receipts, order confirmations, payment records, product pages, shipping details, and product descriptions should be prepared and submitted as required.
Simplified tariff rates may apply to certain international postal items with a taxable value of JPY 200,000 or less, but they do not apply automatically to every item. Split shipments, excluded items, recipient preference, and Customs’ assessment may lead to application of general tariff rates instead.
For unaccompanied articles, the traveler should declare them at entry using the Declaration of Personal Effects and Unaccompanied Articles. The duty-free allowance is assessed by combining accompanied personal effects and unaccompanied articles.
International postal items require checks not only for general import prohibitions and restrictions, but also for postal prohibited items and air dangerous goods. Overseas e-commerce purchases, personal imports, gifts, and samples often create problems involving insufficient price documents, other regulatory checks, prohibited items, unaccompanied article treatment, and return shipment risk.
The key point is to distinguish four separate questions: whether the item can be sent by mail, whether it can legally be imported into Japan, whether its taxable value can be explained, and whether any other regulatory requirements must be satisfied before release.
