Quick answer: The essential features of a product are its core benefit, tangible and intangible attributes, functionality and performance, quality and reliability, design, brand, packaging and labelling, price and value, differentiation, support and service, safety and compliance, and sustainability. Kotler groups these into core benefit, actual product and augmented product.
| Level | Includes |
|---|---|
| Core benefit | Need the product meets |
| Actual product | Features, design, quality, brand, packaging |
| Augmented product | Warranty, delivery, service |

A customer buying a refrigerator is not just buying a cold box. They are buying fresh food for a week, lower electricity bills (the BEE star label tells them how much lower), a brand they trust, a warranty and a service engineer who turns up when the compressor fails. All of that together is the product.
Philip Kotler describes a product in levels: the core benefit, the actual product (features, design, quality, brand, packaging) and the augmented product (warranty, delivery, service). The features below follow that logic. For how products are grouped, see product mix.
12 Essential Features of a Product
1. Core Benefit
Every product exists to solve a problem or meet a need. A drill is bought for the hole, not the drill.
2. Tangible and Intangible Attributes
Physical features (size, material, colour) plus intangibles (brand reputation, service, image).
3. Functionality and Performance
It must do its job well and consistently. Performance is usually the first thing buyers compare.
4. Quality and Reliability
Consistent quality and a low failure rate build repeat purchase. Standards such as BIS certification signal this to buyers.
5. Design and Aesthetics
Looks, feel and ease of use influence choice, often more than specifications.
6. Brand
A name and identity that carry a promise and help buyers choose quickly.
7. Packaging and Labelling
Protects the product, informs the buyer and sells on the shelf. Indian rules require MRP, net quantity and manufacturer details on packaged goods.
8. Price and Value for Money
Buyers judge features against price. The best product at the wrong price fails.
9. Differentiation
A clear reason to choose it over rivals: a feature, a price point, a service promise or a brand story.
10. Support and Service
Installation, warranty, spare parts and after-sales service are part of the product for durables and technology.
11. Safety and Compliance
Products must meet legal safety standards and, increasingly, data privacy rules for connected devices.
12. Sustainability
Energy efficiency, recyclable packaging and repairability matter more to buyers each year, and BEE star ratings make efficiency visible.
