India Expiry Date Labelling in Month and Year Format

1. Key takeaways

The Indian rule on expiry marking is straightforward but strictly enforced: the expiry date is expressed in month and year, and the meaning is that the device is recommended for use until the last day of that month. The date must be preceded by the words “Expiry date” or “Shelf Life”. A full day-month-year format does not comply with the rule.

• The rule removes one element and adds another: no day, but a mandatory prefix.
• The month-and-year convention is a legal presumption that the product remains usable through the end of the month.
• Shelf lives beyond five years require additional accelerated and real-time data, including site sample data.
• Expiry belongs to the factory label layer, while the date of manufacture may sit in the sticker layer.
• Internal consistency between the label, the DMF, and the stability data is checked.

2. Legal basis

The format rule sits in Rule 44(e) and is clarified by the CDSCO’s published FAQ answers, with the accompanying printing and evidence requirements recorded alongside it. The table below sets out the three relevant items.

3. Expert insights

Insight one: this rule is both a subtraction and an addition. What is subtracted is date precision — the day should not be written. What is added is a mandatory prefix — the words Expiry date or Shelf Life must appear. The common error is to perform only the subtraction: the label carries something like 2029-08 with no preceding wording at all. That label fails on the addition, not on the format, and the failure is easy to miss because the date itself looks correct. Reviewers, by contrast, check the field in a fixed order, which is why a mechanical three-point check catches what a visual read does not.

Insight two: “the last day of that month” is a legal presumption. An expiry written as August 2029 legally means the device may be used until 31 August 2029. This is a favourable presumption for device disposal, inventory management, and adverse event traceability, and enterprises do not need to shorten it on their own initiative. Understanding the presumption also matters for distributors, who may otherwise withdraw stock earlier than the regulation requires. In a market where shelf life directly affects tender eligibility, the difference of a few weeks at the end of a month is commercially meaningful.

Insight three: anything beyond five years needs additional evidence. To declare a shelf life longer than five years, accelerated and real-time data conforming to international norms must be provided, including site sample data. For long-life implants and large equipment, this is a dedicated work item in its own right, and it belongs in the project plan well before the artwork is finalised, because the claimed shelf life on the label depends on data that must already exist. Where the data are not yet available, the practical choice is either to declare a shorter shelf life initially or to defer the application until the study package is complete.

Insight four: expiry and date of manufacture sit in different layers of the sticker scheme. Expiry is an element of the factory label, whereas the date of manufacture may be placed in the sticker layer. The two belong to different levels and should not be handled together. Mixing them in one artwork file creates exactly the kind of confusion that leads to a missing prefix or a duplicated field on the printed pack. Keeping the layers separate also means that a change in manufacturing scheduling does not force a reprint of the entire factory label.

4. Practical recommendations

When GRZAN reviews label artwork, it isolates the expiry field and runs three checks: whether the format is month and year, whether the prefix wording is present, and whether the field is consistent with the shelf-life statement in the registration dossier. The third check is the one most often overlooked — a label stating 36 months while the DMF states 24 months is a standard ground for rejection in India, and it is invisible to anyone reading the label on its own.

• Isolate the expiry field in every artwork review and check format, prefix, and dossier consistency in that order.
• Remove the day from any date string before artwork release, and add the required prefix wording.
• Cross-check the claimed shelf life against the DMF and the stability data before printing.
• Plan accelerated and real-time studies early for any product claiming more than five years.
• Keep expiry on the factory layer and the date of manufacture on the sticker layer, as separate fields.
• Brief printers and artwork houses on the prefix requirement, since their templates often omit it.

5. Verification checklist

• □ The expiry format is month plus year, with no day stated
• □ The words Expiry date or Shelf Life precede the date
• □ The label expiry is consistent with the DMF and the stability data
• □ Accelerated and real-time data have been prepared where the claimed shelf life exceeds five years
• □ The expiry is printed on the label, the shelf pack, and the outer packaging
