01 / Identify which field you are reading
Labels may contain ordering code, lot, date code, assembly/test information and pack date. Formats differ by manufacturer; a packing or reseal date should not automatically be read as a manufacturing date. Consult label guidance and retain photos for clarification.
02 / Make the requirement explicit
If a project restricts date range, requires a single lot or prohibits mixed lots, state it during the RFQ. Supply feedback should link lot information to quantities and packing units, explain possible lot splits and identify available labels or records.
03 / Assess date code and storage condition separately
An earlier date does not automatically mean failure, nor does a recent date guarantee suitability. Consider manufacturer guidance, packaging integrity, storage evidence and project requirements. Agree suitable testing separately when solderability, reliability or authenticity is in question.
