If you are only importing/distributing products as originally branded or represented by another company, AND not representing them in any way as your own, then a Declaration ID is not required.
However, you should ensure that the product has been properly qualified by that company by searching the Bluetooth Product Listing Database. Products that appear to not be qualified may be impounded by customs authorities and subject to Bluetooth SIG enforcement actions.
The original manufacturer or branding company must follow the proper branding guidelines to ensure the products are correctly represented and declared/listed as THEIR products. The product information on the packaging and marketing materials must match the product information in the Bluetooth Product Listing Database.
In some instances, if proper trademark usage is not applied to the products, the products may be inherently represented as the importer’s or distributor’s products which can lead to audits and enforcement action brought to both companies to resolve.
