Under the World Trade Organization (WTO) Agreement on Trade in Civil Aircraft ("the Civil Aircraft Agreement" or "CAA"), many civil aviation products and parts are exempt from import duties. Unfortunately, inconsistent application of Customs rules has resulted in the opposite effect.
In addition to having to pay duties, maintenance providers have devoted considerable resources for navigating Customs rules and dealing with conflicting views from exporters, importers and government agents. One major question has been whether the imported part must be airworthy to qualify for duty-free treatment.
The CAA is part of the Tokyo Round of international trade negotiations; it entered into force on Jan. 1, 1980. The signatory countries (including the United States) agreed to eliminate customs duties on articles used in civil aircraft and aircraft manufacture, repair, maintenance, rebuilding, modification or conversion. The agreement also eliminated duties on civil aircraft maintenance activities.
As a "plurilateral" agreement, the CAA is binding only on the World Trade Organization (WTO) members that have signed it. The CAA does not create obligations or rights for WTO members that are not signatories. Fortunately, the United States allows duty-free entry of CAA-covered products and articles regardless of country of origin. So, for example, U.S. imports of Embraer aircraft or parts may be claimed duty-free under the CAA even though Brazil is not a signatory (and is not bound by the CAA to provide duty-free entry into Brazil of U.S. aircraft and aircraft parts).
The CAA covers only civil aviation products and articles. The term "civil aircraft" is defined in the agreement by negation, that is, to mean all aircraft other than military aircraft. In practical terms, aircraft operated by armed forces and national police forces are not covered by the agreement.
The CAA's Annex provides a detailed list of the products and articles exempt from duties under the agreement. The annex specifies 248 items at the six-digit Harmonized System (HS) level. With the exception of a handful (such as helicopters and "ignition wiring sets and other wiring sets of a kind used in aircraft"), most of the listings on the CAA product coverage list are not aviation specific, e.g., pumps, oil filters, tires, generators, tubing, gaskets, hinges, etc. That fact has important implications for how exporters and importers must satisfy Customs Service entry requirements.
The Harmonized Tariff Schedule of the United States (HTSUS) is maintained by the U.S. International Trade Commission (ITC). It is the primary resource for determining the proper tariff (customs duty) classification for imported goods. General Note 6 of the HTSUS prescribes what must be done to enter products duty-free under the CAA; it defines the term "civil aircraft" for purposes of the tariff schedule.
Chapter 88 deals with aircraft and aircraft parts, which fall under heading 8803. The general code for rotors, propellers and related items is 8803.10.00; the general code for undercarriages and related articles is 8803.20.00; the general code for other civil aviation articles is 8803.30.00. Civil aviation items may also be in other HTSUS chapters; according to the notes for HTSUS, articles exempt from duty under the CAA will have a "C" in the "Special" sub-column of the "Rates of Duty" column. ITC provides statistical data for imports in all the various civil aviation related categories. For more information, click here.
(III) What Qualifies for Duty-Free Treatment?
The primary section under Title 19 of the Code of Federal Regulations applicable to the importation of civil aircraft and related articles is 19 CFR § 10.183 ("Duty-free entry of civil aircraft, aircraft engines, ground flight simulators, parts, components, and subassemblies").It explains, among other things, what qualifies for the exemption, how to claim duty-free treatment, and the required certifications and documentation that must be maintained.
(3) Covered by an application for such approval or certificate which will be submitted in the future by an existing type and production certificate holder, pending the completion of design or other technical requirements stipulated by the FAA (applicable only to the quantities of parts, components, and subassemblies as are required to meet the stipulation).
(IV) Does It Matter Whether the Imported Article is Airworthy?
There is no requirement in the regulation or HTSUS that the part be airworthy and Customs rulings support that position.
19 C.F.R. § 10.183 provides details on how to claim, certify, and document duty-free admissions under the CAA. Section 10.183(c) directs the importer to make a claim by identifying the item as qualifying merchandise based upon its status as an article for which the duty rate of "Free (C)" appears on the HTSUS and placing the special indicator "C" on the entry summary or Customs & Border Protection (CBP) Form 7501.
Evidence that a type and production certificate holder will submit an application for certification or approval in the future pending the completion of design or other technical requirements stipulated by the FAA and of estimates of quantities of parts, components, and subassemblies as are required to meet design and technical requirements stipulated by the FAA.
The list was not created by someone familiar with civil aviation safety regulations and is not exhaustive. Generally speaking, the goal of the documentation requirements is to provide evidence that the parts qualify under § 10.183(a).
The documentation does not need to be filed along with the entry summary, but it must be maintained in accordance with the HTSUS and Customs recordkeeping requirements (found at 19 C.F.R. part 163). Customs may request the documents at any time and failure to produce sufficient records will result in the denial of duty-free treatment.
Finally, § 10.183(f) allows an importer to file a claim for duty-free treatment after filing an entry that made no such claim. In other words, if you determine after the fact that you are not required to pay a duty on an imported article, you can file for the exemption and receive a refund of a tariff previously paid. However, the time for doing so is not unlimited. According to the regulation, to do so, you should file a written statement with Customs any time prior to liquidation of the entry or prior to the liquidation becoming final. Liquidation, defined at 19 C.F.R. § 159.1, effectively means the final acceptance by Customs of the duty calculation.
