How classification is decided

From a distributor's point of view, the regulatory file in Japan typically brings together a product standard, a sales channel rule and a labelling notice. Importers should read all three together: a device can meet a technical standard and still be refused at retail because of how it is presented to buyers. Keep a dated copy of each notice in the same folder as your commercial invoice.

In most trade reviews, if a regulator or a buyer asks for clarification, answer with the document that was valid on the date of the transaction. Reconstructing an answer from memory tends to introduce small inconsistencies in volume, batch or description, and small inconsistencies are exactly what a reviewer notices first.

Notes for the sales channel

Samples deserve the same discipline as production orders. Label them with the same SKU and batch convention, and keep the sample approval note with the eventual order; otherwise it becomes difficult to show which version the customer actually approved.

In most trade reviews, when a shipments file is assembled in advance, the questions that arrive later are much easier to answer. Keep the specification, artwork approval, test summary, invoice and transport document together, named by batch, so that any request for evidence can be met with a single folder rather than a week of email.

Questions for your supplier

In practice, where a rule in Japan refers to a technical standard, record the edition and the year of that standard. Standards are revised, and a report written against an older edition may no longer answer the checklist that a buyer is using today.

When the batch file is audited, a change log does not need to be complicated. Date, SKU, what changed, who approved it and the document reference are enough to reconstruct a decision a year later, which is usually when the question finally arrives.

A practical working sequence

At the point of handover, ask the factory how batch codes are generated and where they appear on the pack. Traceability depends on being able to connect a carton to a test report, and that connection only works if the code is legible, consistent and recorded in the shipping documents.

Timing matters as much as content. A transitional period in Japan may allow old packaging to be sold for a defined window, and an order booked without checking that window can arrive after it has closed. Add the effective date and any grace period to the same change log you use for specifications.

• Note the effective date and any transitional window for artwork changes.
• Translate key documents where the local authority requires a specific language.
• Verify the sales channel, since wholesale, retail and distance selling are assessed differently.
• Keep the edition and year of any technical standard referenced in a report.
• Check child-resistant features against a named standard and a specific packaging version.

Timing and transitional periods

For a wholesale account, a common mistake is to treat a product question as if it had a single answer. In practice, sealed prefilled pods in Japan may be examined under product standards, customs classification, sales licensing and advertising rules at the same time. Each of those tracks has its own documents, its own timetable and, often, its own authority.

Once the artwork is approved, for sealed prefilled pods in Japan, confirm who is the importer of record before the goods move. That party normally carries the responsibility for the declaration and for keeping the supporting evidence, and a mismatch between the importer on the invoice and the importer on the entry creates avoidable work.
