Standard documents for all imports

Every commercial shipment entering Japan requires the following core documentation set. These must be provided to your Importer of Record (and ultimately to Japan Customs) for every shipment, regardless of product category.

Commercial invoice format

Japan Customs has specific requirements for commercial invoice content. Invoices that deviate from required format cause clearance delays and may trigger additional inspection.

Required invoice elements:

  • Full legal name and address of shipper (exporter)
  • Full legal name and address of consignee (Japan IOR)
  • Invoice date and invoice number
  • Full description of goods (product name, HS code if known, specifications)
  • Quantity and unit of measure
  • Unit price and total value in declared currency
  • Country of origin (not country of export, if different)
  • Incoterms and shipping terms
  • Net weight and gross weight per line item

Valuation note

Japan Customs uses the CIF (Cost + Insurance + Freight) value as the basis for duty calculation. Ensure your invoice reflects actual transaction value — under-valuation is a customs offense.

Certificates of analysis

For food, beverage, and supplement products, a Certificate of Analysis (CoA) from an accredited testing laboratory is required for the MHLW import notification and may be requested by Japan Customs for additional verification.

Japan-acceptable CoA requirements:

  • Issued by an ISO 17025 accredited laboratory, or a laboratory recognized by MHLW
  • Testing scope must cover: active ingredient potency (for supplements), additive content, microbiological safety, and any contaminants relevant to your product category
  • Results must be expressed in units consistent with Japanese labeling standards
  • CoA must correspond to the specific production lot being imported

Common documentation failures

  • Description mismatch: Product description on invoice does not match packing list or MHLW notification. Any discrepancy triggers review.
  • Missing CoA lot correlation: CoA provided does not reference the specific lot number of the shipment being cleared.
  • Incorrect HS code: Wrong tariff classification leads to incorrect duty assessment and potential re-classification at customs — which delays clearance.
  • Under-valuation: Customs has extensive data on typical import values by category. Significant undervaluation triggers audit.
  • MHLW notification status mismatch: Customs release attempted before MHLW Import Confirmation Notice is issued. Always confirm MHLW clearance before initiating customs filing.
