Models and product identifiers
GTINs, including JAN codes, identify trade items. GS1 Japan explains that brand owners such as distributors, manufacturers or importers assign them. Manage models, SKUs and JAN codes according to their different purposes.
Keep the basis for a price
Before using a suggested retail price in a comparison, check prior publication and how it was actually set. The Consumer Affairs Agency warns that prices set at a particular retailer's request may mislead. A webpage alone does not validate a comparison price.
Keep product information consistent
Align product pages, manuals and support responses. State warranty periods and procedures per product rather than making blanket promises about undecided terms.
- Specifications: material, dimensions, capacity, accessories and use.
- Identification: model, product codes and price effective date.
- Support: manual, precautions and contact details.
