Reading the official text

As a rule of thumb, a declared puff count on pen-style devices in Japan is a marketing figure unless it is tied to a test method and a defined puff profile. Buyers should ask how the number was measured and keep the answer in the product file, since an unsubstantiated claim can be challenged on the carton.

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

When a buyer compares two offers, for wholesale enquiries, a neutral product specification is a better attachment than a promotional deck. It states the measurable facts - dimensions, capacity, materials, batch coding - without making claims that may be interpreted differently in Japan than they were at the point of origin.

At the point of handover, 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.

What the framework actually asks for

Trade buyers in Japan generally prefer a supplier who can explain a gap in the file over one who claims the file is complete. A short note saying which evidence is pending, who owns the action and when it is due is more useful than an unexplained assurance.

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.

Where trade files usually break down

Start by writing down the exact SKU: device type, liquid volume, nicotine statement, packaging version and intended sales channel. Two products that share a brand name can land in different regulatory categories in Japan, and a specification sheet is the cheapest way to make that distinction visible.

• Plan for the operational cost of a held shipment, not only for a possible fine.
• Build one indexed document bundle per batch so a query can be answered in minutes.
• Check whether a take-back or recycling registration applies to the importer.
• Keep the edition and year of any technical standard referenced in a report.
• Check that the test report names the product, the batch, the method and the laboratory.

A practical working sequence

For audit purposes, public guidance in Japan is often published first as a consultation or draft. Reading the draft is useful for planning, but only the final notice should drive artwork approval and purchase commitments; note the status of each source in your change log.

When a buyer compares two offers, currency, Incoterms and duty treatment belong in the same worksheet as the compliance checklist. A change in the sales channel in Japan can alter both the landed cost and the evidence required, and the two should be reviewed together at the quotation stage.
