Production and expiration dates are very important in food, pharmaceuticals, cosmetics and many consumer products. These dates have different definitions and application methods. The concepts of STT (Best Before), SKT (Use By) and TETT (Recommended Use By) have been defined to ensure that consumers can use products safely. In this article, what STT is and the differences between SKT and TETT will be discussed in detail.
What is STT (Best Before Date)?
STT refers to the deadline by which a product can be safely consumed. It is generally used for foods that are prone to spoilage, such as milk, meat, fish and chicken. The use of expired products may pose a health risk and should not be consumed.
- Who is it Important for?
- Food consumers
- Restaurants and catering services
- Grocery stores and retailers
- Can STT Expired Products be Used?
- Absolutely not. Foods that are prone to spoilage pose health risks.
What is the SKT (Expiration Date)?
SKT is a dating system used especially in pharmaceuticals and cosmetics. It indicates that a medicine or cosmetic product may lose its effectiveness or become harmful after the specified date.
- In which products is it used?
- Medicines
- Cosmetics and personal care products
- Medical devices
- Can Products Past the SKT Be Used?
- Not recommended. Its effectiveness may be reduced or it may become harmful.
What is TETT (Recommended Consumption Date)?
TETT indicates that food products can be consumed in the best quality and taste until the specified date. However, even if this date has passed, the product can be consumed if it is intact and stored under appropriate conditions.
- In which products is it used?
- Canned foods
- Dry foods (pasta, pulses, etc.)

Main Differences between STT, SKT and TETT
| Feature | STT (Best Before Date) | SKT (Expiration Date) | TETT (Recommended Consumption Date) |
|---|---|---|---|
| Area of Use | Perishable foods | Pharmaceuticals, cosmetics and medical products | Durable foods |
| Use After Passing | Definitely should not be consumed | Not recommended, may lose effect | Generally consumable |
| Health Risk | High | Middle | Low |
| Sample Products | Milk, meat, fish, chicken | Medicines, creams, vitamins | Pasta, pulses, chocolate |
Conclusion
STT, SKT and TETT dates are very important for consumers to use safe food and products. Products with expiry dates must be consumed by that date, while products that have passed the recommended consumption date can be consumed when stored under appropriate conditions. For pharmaceutical and cosmetic products, if the expiry date has passed, it is recommended not to use them as they may lose their effectiveness. Consumers should be aware of these differences so that they can shop more consciously and protect their health.
