Planning the first shipment

At the quotation stage, a declared puff count on sealed prefilled pods 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.

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.

Documents worth preparing early

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.

During a documentary review, 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.

What to confirm with the authority

For a wholesale account, 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.

For a wholesale account, 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.

Common points of confusion

For a first order, price discussions should be separated from compliance discussions. A lower unit price is not a saving if the artwork has to be reprinted or a batch held for review, so it is worth agreeing the document set before agreeing the commercial terms.

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.

• Verify the sales channel, since wholesale, retail and distance selling are assessed differently.
• Verify that the declared puff count or capacity is tied to a stated test method.
• Agree in writing who is the importer of record and who retains the evidence.
• Check that the test report names the product, the batch, the method and the laboratory.
• Confirm the current official text rather than relying on a summary or a reseller's note.
• Keep a dated change log with document references for every specification revision.

Timing and transitional periods

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.

Once the artwork is approved, 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.
