Questions for your supplier

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.

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

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.

At the point of handover, 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.

Where trade files usually break down

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.

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.

Timing and transitional periods

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.

For a mixed SKU consignment, never assume that a nicotine-free variant of Prefilled Pod is automatically outside the framework in Japan. Classification frequently follows the device category or the intended use, so each variant needs its own short assessment before it is added to a catalogue.

• Check whether a take-back or recycling registration applies to the importer.
• Verify the sales channel, since wholesale, retail and distance selling are assessed differently.
• Confirm whether a product notification is required and who is entitled to file it.
• Record the official regulator name, website and the date it was last checked.

A practical working sequence

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.

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.
