Rules change, and a page like this should be treated as a starting point for a conversation with a qualified local adviser.

Documents worth preparing early

In practice, ingredient review for pen-style devices in Japan looks at the liquid formulation and, increasingly, at the materials in contact with it. Request the full composition declaration from the factory and check that the version number matches the batch you intend to buy, not an older product revision.

For audit purposes, 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.

Evidence a buyer will ask to see

When the batch file is audited, 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.

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.

Questions for your supplier

Before the booking is confirmed, 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.

In practice, 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.

What the framework actually asks for

For a mixed SKU consignment, 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.

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.

• Confirm whether a product notification is required and who is entitled to file it.
• Check child-resistant features against a named standard and a specific packaging version.
• Separate the device, the liquid and any accessories when checking classification.
• Verify the sales channel, since wholesale, retail and distance selling are assessed differently.
• Check whether a take-back or recycling registration applies to the importer.
• Match the product description across the invoice, carton, packing list and listing.

Where trade files usually break down

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.

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.
