Japan's Food Sanitation Act and JIS Requirements for Imported Kitchen Knives

Japan tests the article, not the factory's paperwork. For kitchen knives entering Japan, the governing framework is the Food Sanitation Act and the specifications for apparatus, containers and packaging set out under it. Compliance is demonstrated by the finished product meeting leaching requirements, with an import notification filed before the goods clear.

This article outlines how the framework applies to cutlery and what an importer should prepare. It is a planning outline — confirm current requirements with a Japanese customs broker or the importing authority before shipment.

The two pillars

1. The Food Sanitation Act and the import notification

Importers must file a notification of importation for food, apparatus, containers and packaging. Cutlery falls in the apparatus and containers category. The notification is reviewed by the quarantine station, which may accept the submission, request additional information, or inspect and test. Goods cannot clear customs without it.

2. The material specifications

Specifications for apparatus and container-packaging materials are set out in a ministerial notification that establishes, for each material class, the allowable composition and the leaching limits. For metal articles the relevant part is the metal section, which sets out requirements including the material composition and limits on metals that may leach into a food simulant under specified conditions.

The key practical point: Japan regulates the finished article as it will be used, with tests performed on the article itself under specified conditions. A certificate about the raw steel is supporting evidence, not a substitute for article testing.

What gets tested, and how the test is framed

Metal apparatus testing focuses on leaching. The article is exposed to a simulant for a defined time and temperature, and the resulting solution is analysed for specified elements. For cutlery the practical test set covers the elements that can leach from the steel or from any coating.

Exact limits and test conditions are set by the current version of the specification and may be revised. Do not build a specification from a second-hand table. Ask the testing laboratory to confirm the applicable items and conditions for your specific material and use case, then hold that test report in the compliance file.

Surface condition is not a detail

Two knives made from the same coil can test differently. Factors that move the result:

• Grade. Higher free chromium generally reduces metal release; heavy carbide-forming grades can behave differently from what the chromium content alone predicts.
• Passivation and finishing. Residual free iron on the surface from grinding or from contact with mild steel tooling is a common cause of elevated iron and, in some tests, of apparent corrosion products.
• Contamination from processing. Grinding swarf, polishing compound residue and handling after cleaning.
• Coating integrity. Any coating must be assessed as part of the article, and a damaged coating is a different article for testing purposes.

The practical consequence: test the article in the condition it will be shipped, taken from the actual production run, not a hand-finished sample. This is the same discipline as an AQL inspection — the sample must represent the population.

JIS and the relationship to the regulatory tests

Japanese industrial standards for cutlery address the product as a manufactured article: dimensions, materials, performance and marking. They are not themselves the food contact law, but they serve as the recognised basis for specifying a product and for the factory's own testing.

For a knife programme, the useful approach is to write the purchase order against both: the JIS-based product requirements for the article, and the Food Sanitation Act leaching requirements for the food contact aspect. A single test report does not cover both.

Packaging is also covered

Containers and packaging are in scope. A knife packed in a printed carton with a plastic insert puts that carton and insert in scope as food contact articles where they contact the knife or could transfer to it. Paper, board, plastic and any ink or adhesive may need to be supported by evidence.

This is the same exposure that packaging food contact compliance describes for other markets, and it is why packaging changes should be run past compliance rather than treated as a print job.

What to prepare before the first shipment

Build the file before the first order, not after. Compliance documents assembled retroactively are the most common reason a first shipment to a new market sits in a warehouse — a pattern that repeats in other regulated markets.

FAQ

Can I rely on an EU LFGB test report for Japan?

No. Different elements, different limits, different simulants and conditions. A test report is specific to the regime it was performed against.

Does the factory need to be registered in Japan?

The notification duty sits with the importer, not the factory. The factory's role is to provide accurate material information and to make the article consistently, so that the tested sample remains representative.

How long does the first clearance take?

It varies with the commodity and whether inspection or testing is requested. Plan the first shipment with more time than later ones, and confirm current practice with your broker.

What if the grade changes later?

A material change invalidates the basis of the test report. Any change in steel, coating, finish or production site should trigger a review of whether retesting is needed. See supplier handover for why this is a documented step rather than a verbal one.
