As the dust settles following UK Chancellor Gordon Brown's budget yesterday, Apple's beancounters have their own "Cupertino" tax - a tithe on the iPod accessories market.

Cnet confirms rumours Macworld's heard from sources claiming Apple wants 10 per cent of the wholesale price iPod accessory manufacturers charge in exchange for the right to take part in the "Made for iPod" logo scheme.

The ten per cent charge will most likely be passed on to iPod users in the form of raised prices.

Apple's one in ten

While manufacturers benefit from their products' possible inclusion in Apple's brick-&-mortar and online retail stores, Apple wants ten per cent of the wholesale product price, and wants that percentage levied against all wholesale prices.

Cnet reports that "Apple was at one point looking to get ten per cent of an add-on's retail selling price."

Apple describes the scheme as an attempt to clarify the market for consumers, who may be overwhelmed by the sheer breadth of choice. Larger providers such as Belkin and Griffin have already confirmed plans to take part in the scheme.

Manufacturers fail to reach consensus

Griffin Technology CEO Paul Griffin told Macworld: "The 'Made for iPod' scheme is designed to ensure that electronic accessories work properly with iPods. It only applies to accessories that attach electrically and does not effect other products such as cases. There are no requirements or implications for vendors," he said.

Some smaller manufacturers are refusing to participate in the scheme, with CEO Jack Campbell of DVForge telling Cnet that his company "won't play".

Analysts estimate Apple may add another $25 million each year through the scheme.

Apple has insisted that manufacturers wanting to build products to exploit the remote or Dock connectors on an iPod buy component parts from approved partners for some time.

This has annoyed some manufacturers who felt they would be able to buy or make such components cheaper on their own.

However, more established players are more sanguine. AM Micro managing director (and distributor of many iPod products), Steve Hawkins said: "It should kill-off cheap and nasty knock-offs", he said.
