9706 - Antiques of an age exceeding 100 years:

This category, HTS Code 9706, encompasses antiques that have reached an age exceeding 100 years. It specifically includes objects that have achieved historical significance and artistic merit due to their age. This classification is distinct from other categories within Section XXI, such as those for live animals (Chapter 01), which focus on biological organisms and their primary purpose rather than historical preservation or artistic value. The fundamental criterion for classification under 9706 is the item's age, exceeding a century, distinguishing it from newer decorative or functional items.

Within HTS 9706, further distinctions are made based on the specific age of the antique. Subcategory 9706.10.00 is designated for antiques exceeding 250 years of age, representing items of even greater historical depth and rarity. The residual subcategory, 9706.90.00, covers all other antiques over 100 years old but not meeting the 250-year threshold. This hierarchical structure allows for a more granular classification of artifacts based on their demonstrable historical longevity.
