Aircraft Parts Exceptions to the 10% Section 122 Duty under Tariff Code 9903.03.01

Even though the Court of International Trade has ruled that the 10% section 122 tariff on most imports is illegal, it is still being collected while the matter is on appeal. It is therefore especially important to know when your imported parts are excepted from this duty (and most civil aircraft parts are now excepted).

The 10% duty that is charged under the section 122 tariff is described at HTSUS 9903.03.01.

Some imported aircraft parts from some may enjoy specific exceptions from the tariff collection, but you (or your customs broker) need to declare the exception tariff on your entry documents. In order to take advantage of the tariff exception from the 10% section 122 tariff, the imported part must meet one of these conditions:

1. The part’s base HTSUS classification (its tariff code) must be listed on a list of codes that applies to the particular source country (and these lists vary by country, so you need to verify the applicability each time) [the references are found in the table below], or
2. The part’s base HTSUS classification (its tariff code) must be listed on the general list of codes found in HTSUS Chapter 99, Subchapter III, U.S. Note 2, subdivision (aa)(iv).

The jurisdictions that enjoy expanded section 122 tariff exceptions for aircraft parts imports include:

Some jurisdictions have fairly short lists – for example Taiwan has a shorter list that does not include the “standard” 8807 heading for many aircraft parts. Imports from Taiwan that do not benefit under the Taiwan provisions may benefit from the “any country” provisions found in HTSUS 9903.03.05.

It is important to note that the analysis for identifying an aircraft parts exception to the 10% section 122 duty is different from the analysis for exception from base duties under the Agreement on Trade in Civil Aircraft. For most parts one may get the same answer for both, but for other parts the answers may differ!

Example: If you have a brazed aluminum plate fin heat exchanger then the tariff code is 8419.50.10; this is classified with a “C” in the HTSUS so it is excepted from the 4.2% base tariff. This tariff code is also found in the list associated with 9903.03.05, so the unit is excepted from 10% section 122 tariff found in chapter 99. This unit enters duty-free, with an exception from both the base duty and also the 10% section 122 duty described under HTSUS 9903.03.01.

This is just one of the many import regulations that we will be learning to navigate at the ASA/AFRA Annual Conference, on June 14-16, in Las Vegas, Nevada. Check out the conference agenda for full details on this and many other workshops available at the conference!
