Questions for your supplier

When the batch file is audited, 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.

For audit purposes, 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.

Record-keeping that holds up

Buyers in Japan often ask whether a document issued in one market can be reused in another. Sometimes it can, but the unit of measurement, the language and the referenced standard frequently differ. A translation and a short cross-reference note are usually needed before the same report is useful twice.

For a first order, regulatory summaries written for consumers rarely cover the questions a distributor has to answer. A B2B file in Japan needs the trade-specific details: who may sell to whom, what evidence must be retained, and for how long.

Evidence a buyer will ask to see

On a repeat shipment, 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.

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.

What the framework actually asks for

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.

In practice, 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.

• Record the official regulator name, website and the date it was last checked.
• Record the exact SKU, packaging version and batch code before requesting a quotation.
• Keep the edition and year of any technical standard referenced in a report.
• Verify the sales channel, since wholesale, retail and distance selling are assessed differently.
• Review downstream retail partners' licence records as part of account setup.

A practical working sequence

As a rule of thumb, training the team that answers customer questions is part of compliance. A short internal note explaining which statements are factual, which are pending confirmation and which should be escalated prevents a casual reply from becoming an unintended product claim.

Photographs of the outer carton, the inner pack and the product markings are cheap insurance. They take minutes to collect at the factory and can settle a description dispute in Japan without waiting for a physical re-inspection.
