Where is the DHC batch code usually printed?
Start with box flap / bottle base, then check any label edge, crimp, seal, or sticker. Use one short complete lot string, not the barcode, shade name, or product reference.

DHC batch-code checks work best when you first identify the right printed lot string, then judge the result against product type, seller channel, and storage history.
DHC FAQ
Why can a decoded DHC result look older than the purchase date?
Import and marketplace stock can vary in age and labeling. A decoded date can reflect production before retail sale, so it should be read with seller turnover, packaging condition, and official labels.
Can this DHC batch code prove authenticity or safety?
No. The code is a freshness and stock-rotation signal. Authenticity and practical safety still depend on seller reliability, packaging quality, PAO, storage, and current product condition.
