Questions for your supplier

Wholesale buyers in Japan are usually judged on the documentation they can pass down the chain, not only on the goods they receive. A practical file for sealed prefilled pods includes the supplier declaration, batch test summary, artwork approval and a record of which customer received which batch.

When a buyer compares two offers, 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.

Common points of confusion

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.

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.

Notes for the sales channel

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.

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.

What to confirm with the authority

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.

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.

• 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.
• Translate key documents where the local authority requires a specific language.
• Check child-resistant features against a named standard and a specific packaging version.
• Confirm whether a product notification is required and who is entitled to file it.
• Agree in writing who is the importer of record and who retains the evidence.

A practical working sequence

From a distributor's point of view, 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.

From a distributor's point of view, 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.
