Q:  Which AES software vendor do you recommend?

A:  We do not endorse any particular vendor, but we do list all companies that have developed certified AES software at http://www.census.gov/foreign-trade/aes/documentlibrary/vendors.html. The companies listed here have developed software that has been tested and approved by U.S. Customs and Border Protection.

Q:  I want to develop in-house software for AES.   Can you give me the technical specifications?

A:  The AES accepts data programmed using the Customs Proprietary Record Format or the ANSI X.12 Format.  The specifications for each of these formats are provided in the AES Technical Interface Requirements (AESTIR) documentation at http://www.cbp.gov/xp/cgov/trade/automated/aes/tech_docs/aestir/june04_intro/.

Q:   I don’t always know all the information about a shipment prior to departure, what should I do?

A:  The AES allows you to report estimated data prior to departure and then to update any or all such information as soon as you confirm the actual details.
Remember, the FTR requires you to report shipment data prior to exportation, unless the USPPI is approved for postdeparture reporting.
   

Q:  What is an export commodity code, and how do I find out how to classify my export cargo?

A:   In order to complete the EEI, you must report a commodity code for unlicensed cargo valued over $2,500, or for licensed cargo, regardless of value. The AES requires a 10-digit code from the Harmonized Tariff Schedule (HTS) or the Schedule B (Export Commodity Classifications).  HTS import codes may be used, in most cases, with exceptions noted in the AESTIR, Appendix V—HTS Numbers That Cannot Be Reported in AES”.  For classification assistance, please call 800-549-0595, Menu Option 2. 

NOTE:  Although import codes can be used in the AES, the reverse is not true.  Export codes cannot be used in import reporting, except when the 10-digit codes are exactly the same.

Q:  Where can I get copies of the Federal Register notices on AES filing?
  

A:  Please visit the Census Bureau’s Foreign Trade Division website at www.census.gov/foreign-trade/regulations/fedregnotices/index.html.

Q:  What is the Commerce Control List (CCL), and what are the associated AES filing requirements?

A:  The CCL is a listing of export commodities that require extra scrutiny by the
U. S. Department of Commerce.  These include items such as precursor chemicals, certain hazardous materials, technical items and products as designated from time to time.  The list is maintained by the Bureau of Industry and Security (BIS).  The BIS is responsible for the Export Administration Regulations (EAR), which contain the CCL under Part 774, Supplement No. 1.  For an alphabetic index to the CCL, go to www.access.gpo.gov/bis/ear/pdf/indexccl.pdf.  For assistance, please call the BIS Help Desk at 202-482-4811.

Q:  Which Bureau of Industry and Security (BIS) license codes or license exceptions require a license number and/or an Export Control Classification Number (ECCN)?

A:  Requirements vary from license to license and to license exceptions.  Please see the chart in Appendix F of the AES Technical Interface Requirements (AESTIR) at "http://www.cbp.gov/trade/aes/aestir/appendices.

Q:  What is the format for the Export Control Classification Number (ECCN)?

A:  The ECCN is a five-character code in the format of NANNN, where N is a numeric character and A is an alpha character.  If the ECCN is not in this format, the AES filer will receive a Fatal Error message.  The filer must use a valid ECCN, as determined by the BIS.  For assistance, please call the BIS Help Desk at 202-482-4811.

Q:  What is the United States Munitions List (USML) and what are the associated AES filing requirements?

A:  The USML is established under the International Traffic In Arms Regulations (ITAR) (22CFR Parts 120-130), administered by the Directorate of Defense Trade Controls (DDTC), an agency of the U. S. Department of State. This list includes articles, services, and related technical data controlled by the U.S. Department of State.  AES filing is required for licensed cargo under DSP-5, DSP-61, DSP-73, DSP-85, and DSP-94, and for certain agreements and license exemptions as defined in the ITAR, regardless of value.

An additional data record is required in the AES for DDTC shipments.  This is called the ODT record and must include the following additional data elements:

DDTC Export License Number
DDTC Exemption Number
DDTC Registration Number
DDTC Significant Military Equipment Indicator
DDTC Eligible Party Certification Indicator
DDTC United States Munitions List (USML) Category Code
DDTC Unit of Measure Code
DDTC Quantity
