Compliance Answer: Japan’s Revised Agricultural Chemical Residue Limits under the Food Sanitation Act

Direct Answer

Japan has updated its maximum residue limits (MRLs) for agricultural chemicals in foods and food additives under the Food Sanitation Act, effective after a public comment period ending 18 September 2026. The revisions align with scientific and health guidelines, apply to all trading partners, and include both new MRLs and updates to existing standards. Adopted MRLs are published in the Kampō (Official Gazette) and take effect after a grace period^{1, 2, 3}.

Regulation Analysis

1. Legal Framework and Authority

The revisions are governed by the Food Sanitation Act (Act No. 233 of 1947), administered by the Consumer Affairs Agency (CAA). The Act establishes specifications and standards for food safety, including MRLs for pesticides and veterinary drugs^{1, 4, 5}.

2. Scope of Revisions

The updates cover:

• Pesticides: Prosulfocarb⁵, Triforine⁴, Tetraniliprole⁶, Kasugamycin², Mepronil¹, Carbaryl³, Polyoxorim-zinc⁷, Ethaboxam⁸, Picarbutrazox⁹, Esprocarb¹⁰.
• Product Categories: Aquatic animals, honey, vegetables, fruits, spices, cereals, oil seeds, and animal/vegetable fats/oils (HS codes listed in^{5, 3}).
• Applicability: All trading partners^{1, 4, 5, 2, 3}.

3. Key Requirements and Process

4. Compliance Obligations

• For Businesses:
  • Ensure imported/exported foods comply with updated MRLs post-publication^{1, 5}.
  • Monitor Kampō for finalized MRLs (published in Japanese)^{1, 7}.
• For Regulators:
  • The National Enquiry Point (Ministry of Foreign Affairs) handles comments and provides draft texts^{2, 3}.
  • Contact: `enquiry@mofa.go.jp`; Fax: +81 3 5501 8343^{2, 3}.

5. International Standards

• Conformance: Some MRLs align with Codex standards (e.g., Triforine⁴, Tetraniliprole⁶, Carbaryl³).
• Deviations: Where no international standard exists (e.g., Prosulfocarb⁵, Kasugamycin²), Japan sets independent limits based on domestic risk assessments.

6. Adopted MRLs (Examples)

The following MRLs were finalized and published on 16 December 2025:

• Polyoxorim-zinc⁷
• Ethaboxam⁸
• Picarbutrazox⁹
• Esprocarb¹⁰

Summary Answer

Japan’s revision of agricultural chemical residue limits under the Food Sanitation Act introduces updated MRLs for pesticides/veterinary drugs, effective after a 60-day public comment period ending 18 September 2026^{2, 3}. The revisions apply universally to all trading partners^{1, 5} and include both Codex-aligned standards (e.g., Triforine⁴) and Japan-specific limits (e.g., Prosulfocarb⁵). Adopted MRLs are published in Kampō and take effect after a grace period^{1, 7}. Stakeholders must submit comments to the National Enquiry Point^{2, 3} and comply with finalized limits post-publication. For details, refer to the Food Sanitation Act¹ and WTO notifications^{4, 5, 6, 2, 3, 10, 8, 7, 9}.
