Amazon has published new product attribute data for pretty much all of their US categories in the form of new Item Classification Guides (ICG) as well as Browse Tree Guides (BCG), essentially which category and subcategory you need to insert your products into to maximize your sales (after all a mis-categorized product not only will score poorly in tree navigation but also in search).

This type of update occurs about every six months or so and this time includes the following categories:

• Apparel
• Automotive
• Baby Products
• Camera & Photo
• Electronics
• Gourmet Foods
• Health & Personal Care
• Home & Garden
• Home Improvement (formerly Tools & Hardware)
• Jewelry
• Musical Instruments
• Office Products*Pet Supplies
• Software
• Sporting Goods
• Toys & Games
• Video Games
