This is the final blog post in the Export Classification Codes blog series that discusses the proper way to classify mixtures, kits or parts for exports.

This blog post discusses how to classify parts according to the Additional U.S. Rule.

According to Additional U.S. Rule 1B, goods that are specifically provided for in Schedule B must be classified as such and not as “parts”.

Aircraft seats and windshields have their own Schedule B numbers: 9401.10.0000 and 7007.21.1000, respectively. For that reason, it would be unacceptable to classify either product as aircraft parts.

However, sometimes the classification will depend on what the product will be used for.

For example, titanium screws for medical implants are classified under Schedule B 9021.10.0050 – Bone plates, screws and nails, and other internal fixation devices or appliances

while titanium fasteners for aircraft are classified under Schedule B 8108.90.0000 – Other articles of titanium.

Our interactive Schedule B Search Engine takes into account these and the other General Rules of Interpretation to provide export classification codes.
