Authorised Dealer Code requirement: AD Code must be declared in the Bill of Entry to validate outward remittance and filing. Declaration of an Authorised Dealer (AD) Code is mandatory in the Bill of Entry main table (a seven digit code) though prior registration is not required; UCR fields may be left blank pending notification. The Enduse field is converted from free text to a coded value from published directories and must be entered as code only. Payment Method Code is mandatory with a default transaction indicator. Multiple new fields and tables (third party payee, manufacturer/source/transit country, HSS preceding level, INFO_TYPE/INFO_QUALIFIER/INFO_CODE, control codes) are introduced, with several fields permitted to remain blank until agency guidance is issued.
