Four Types of Labels: A Comprehensive Guide and Application Insights
In daily life and business operations, labels are omnipresent. They can be found on courier packages, supermarket products, warehouse shelves, and even on medicine bottles. Labels help us quickly identify information, classify data, optimize search results, and even train intelligent algorithms. So, what are the four common types of labels? Today, let’s delve into these four main types of labels and their applications in different scenarios.

1. Shipping Labels

Usage: For identification and tracking of parcels during logistics.
Typical Scenarios: E-commerce shipping, cross-border delivery, and corporate document sending.
Content:
•  Sender and recipient addresses
•  Tracking number
•  Barcode or QR code
•  Service type (e.g., “Next Day Delivery,” “Standard Ground”)
Characteristics: These labels are usually free to generate online and serve as the “ID card” of the logistics chain.
Note: The label must be clear and applied smoothly to avoid delivery failure.

2. Product Labels

Usage: To provide basic information, ingredients, usage instructions, and compliance markings for products.
Typical Scenarios: Food packaging, cosmetics, electronics, and pharmaceuticals.
Content:
•  Product name and brand
•  Ingredients or list of components
•  Production date and expiration date
•  Manufacturer information
•  Safety warnings or certification marks (e.g., CE, FDA, QS)
Characteristics: These labels combine marketing and legal compliance functions, directly affecting consumer trust. When selling across borders, they must also comply with the language and labeling regulations of the target country.

3. Price Labels

Usage: To indicate the price of goods, facilitating customer decision-making and checkout.
Typical Scenarios: Supermarket shelves, clothing stores, convenience stores, and online malls (electronic price tags).
Forms:
•  Handwritten or printed paper price tags
•  Electronic shelf labels (ESL)
•  Barcode labels (containing price information, scanned to reveal)
Characteristics: Emphasis on clarity, accuracy, and ease of updating. They are often used in combination with “discount labels” during promotions.
Tip: Using a uniform format for price labels can enhance the professionalism of the store.

4. Inventory/Warehouse Labels

Usage: For internal inventory management, locating storage positions, and tracking inbound and outbound movements.
Typical Scenarios: Warehouse shelves, logistics centers, and e-commerce storage areas.
Content:
•  SKU code (Stock Keeping Unit)
•  Storage location number (e.g., A-03-02)
•  Batch or serial number
•  QR code (linked to ERP/WMS systems)
Characteristics: Focus on durability (waterproof, tear-resistant) and machine readability (supporting quick identification with barcode scanners). An efficient warehouse labeling system can significantly increase picking speed and inventory accuracy.
