KYO Lot Mark Guide

Before checking a KYO date, identify the exact product and package format. The variable line may sit at rear panel or carton flap; container base and closure area help recognise a shallow embossed line.

KYO FAQ

Could the shallow embossed line on KYO appear on either rear panel or carton flap?

Start with rear panel, carton flap, container base and closure area. Keep shallow embossed line tied to the surface where it appears, and show enough surrounding label text to relocate the mark later.

How can the KYO shallow embossed line on rear panel be kept separate from barcode and PAO information?

Read the KYO shallow embossed line independently of its barcode, size, shade or scent, distributor reference and PAO symbol. Compare shallow embossed line at rear panel with any variable print at closure area; shade, scent and size references identify variants rather than production timing.

Is the KYO shallow embossed line near rear panel or carton flap enough to judge the product's condition?

For KYO, a shallow embossed line on rear panel or carton flap is only a timing clue. Record any second variable mark on container base separately. Assess odor, colour, seal, dispensing and storage history directly.

Reading KYO date and lot-marking guide

Before you rely on the decoded date

  • Start at rear panel, then move through carton flap, container base and closure area. Copy shallow embossed line as one uninterrupted line, keeping its print style and exact surface noted while checking one package panel at a time.
  • Do not merge shallow embossed line with fixed retail copy such as the barcode, size, shade, scent, distributor number or PAO. Compare rear panel with closure area while checking one package panel at a time before assigning a purpose to either line.

Common lookup mistakes

  • Record a wide KYO package view before the close-up of shallow embossed line. Add rear panel, carton flap and container base in sequence and avoid mixing components from a set.
  • After opening KYO, check odor, colour, seal and dispensing directly; its package date cannot answer those condition questions. If rear panel and closure area do not agree, retain both locations and keep storage history separate from the manufacturing estimate; an estimated date does not override deterioration or uncertain storage. Keep the direct container beside its own carton during this comparison.

What to check next for KYO

For KYO, combine the decoded date with product type, PAO, storage, and seller context before deciding whether to open, keep, replace, or buy.
