DHC batch code & expiration date

Where to find your DHC batch code

On real DHC packaging (made by DHC Corporation) — green is the code, red is not (the barcode, article number or open-jar symbol):

✓ The batch code is HBZTS

✗ Not the code: CA94111, 6M (open-jar / PAO), 0800 23 24 25

The DHC batch code — also called the lot code, lot number or serial number — is a short 4–8 character stamp of letters and numbers, usually embossed rather than printed in ink, and it is never the barcode. On a bottle or jar look at the base; on a tube look near the crimp/seal at the end; on a boxed perfume or fragrance check a flap or side of the box; on makeup check the underside of the compact or inside the pan.

• Bottle / jar — stamped on the base.
• Tube — near the crimp or seal at the closed end.
• Boxed fragrance — a flap or side of the outer box (and often on the bottle base too).
• Compact / palette — the underside, or inside the pan.

About DHC batch codes

DHC codes encode a mapped year code, a month letter and the day.

Real documented examples: code → manufacture date.

Most unopened cosmetics and fragrances keep for about 30–36 months from manufacture. Once opened, follow the PAO (open-jar) symbol — it usually matters more than any printed expiration date.

We've read 113 DHC batch codes so far, the newest was made August 2026, and the typical DHC product people check here is about 29 months old.

Can the batch code tell me if my DHC is authentic? Not on its own. A code that decodes to a sensible date is a good sign, but counterfeiters copy real codes from genuine packs, so a valid code cannot prove a DHC product is authentic. Buy from DHC or an authorised retailer, and compare the packaging, print quality and seal with one you know is genuine.

Does DHC expire?

Yes — like all cosmetics and fragrances, DHC products have a limited shelf life. Unopened they typically last 30–36 months from the manufacture date, and the batch code above tells you how old yours already is. After opening, the PAO (open-jar) symbol — e.g. "12M" — is a better guide than any printed expiration date.

How long DHC products last

Unopened: general cosmetics guidance. Opened: general guidance by product type. A date or open-jar symbol on your pack always wins.
