This EDI ASN Implementation Guide is intended for trading partners that elect to remove DSCSA lot-level data from their ASN implementations now that DSCSA package-level requirements are in full effect and that intend to address the U.S. Customs and Border Protection purchaser import notice requirement. The guide also provides a systematic way to give trading partners advance shipment information, helping them better plan for and automate the receipt of goods. Trading partners seeking the DSCSA lot-level product tracing ASN can find that guide here.
