Do you have a description of Avantor Performance Materials lot number system?

On April 30, 2012, Avantor Performance Materials implemented SAP's Enterprise Resource Planning (ERP) system for our United States facilities. Due to the system changeover, products are now labeled with a Batch Number insteadwith a Lot Number. The Batch Number is synonymous with Lot Number. The following information describes our Batch/Lot Numbering System.

SAP System Batch Number

J.T.Baker and Macron Fine Chemicals products display a 10 digit batch number on the container label. Batch numbers are generated by SAP numbering system. Each batch of product is assigned a sequential, non-repeating batch number that consists of 10 numerical digits. The batch number does not contain any encoded date or plant information.

Legacy System Lot Number

J.T.Baker and Macron Fine Chemicals products display a 6 character lot number on the container label. Each lot of product is assigned a unique lot number, and can be explained as follows.

  • The first character is a letter, designating the year. The schedule of letters is:
    2000 = T2005 = B2010 = J
    2000 = V2006 = C2011 = K
    2002 = X2007 = E2012 = L
    2003 = Y2008 = G 
    2004 = A2009 = H 
  • The second and third characters indicate the week of the calendar year in which the lot number was assigned; i.e. all lot numbers assigned in the first week of the year would be 01.
  • The three remaining characters represent an internal manufacturing identifier, represents a unique lot of material, and may be numeric or alphanumeric, e.g. 015 or C30.

For example, Lot Number L16A06 corresponds to the 16TH week in 2012.
