What is the rules and criteria of eggshell marking

Eggshell marking may seem like a straightforward process, yet it plays a crucial role in guaranteeing the safety and traceability of eggs. Let's delve into the significance of directly marking on eggshells, explore the regulatory landscape, and understand the specific requirements involved in this crucial process.


1. The importance of eggshell marking


Marking on eggshells is not merely for aesthetic purposes; it is a necessity driven by regulatory compliance, contributing to quality control and traceability.


Countries worldwide have established specific regulations for eggshell marking to ensure that eggs adhere to predefined standards and requirements. Adhering to these regulations is imperative for global sales, as it ensures compliance with import and export standards on a global scale.

Quality Control

The information marked on eggshells, including the production date and best eating date, serves as a vital quality control measure. This data enables consumers to assess the freshness and quality of the eggs they purchase, thereby promoting transparency and consumer confidence.


In situations involving contamination, food safety concerns, or recalls due to outbreaks, traceability becomes paramount. Eggshell marking facilitates swift identification and recall, reducing the potential spread of foodborne illnesses. In times of crisis, the ability to trace eggs back to their source is crucial for effective and targeted intervention.


2. The requirements of eggshell marking

Visibility & Durability

Even with a small font size, the markings are visible, ensuring they remain in place over time, even in humid and harsh environments where condensation may occur.


Eggshell markings should neither weaken nor penetrate the shell, ensuring that the markings do not compromise the quality and safety of the eggs.

Certified Ink

Using food-grade ink is imperative for eggshell marking. This ink must be safe for human consumption, maintaining its safety whether the egg is raw or cooked.


3. The criteria for certified Ink

In the intricate world of food safety, where every detail matters, food-grade ink plays a pivotal role. The choice of food-grade ink is driven by its compliance with food safety regulations, ensuring it is non-toxic and safe for human consumption. Meeting specific criteria for safety, composition, and usage in food-related applications, food-grade ink follows Good Manufacturing Practices (GMP).

Three main points:

Allergen-Free, Odorless and Tasteless

To reduce the risk of allergic reactions among consumers and to avoid any impact on the flavor of the eggs.

Anti-condensation & Strong Adhesion

To maintain long-term stability and resistance in various humid and harsh environments. To prevent smudging and ensure the longevity of the markings.

Avoid Migration & Gas-phase Transfer

The ink component cannot penetrate the substrate. Avoid volatile ink substances interacting with the air in the packaging and affecting food quality.
