Introduction
Shipping inkjet printer inks internationally requires more than just packaging and labeling. Due to their chemical compositions—often including volatile solvents—many inks are considered hazardous materials. The United Nations (UN) assigns specific classification codes to these materials to regulate their transport under international frameworks such as IATA (air), IMDG (sea), and ADR (land). This article breaks down the UN classification of inkjet inks, why it matters, and how you can ensure your shipments comply with international transport laws.

1. What Is UN Classification?
The UN classification system assigns a four-digit number (UN number) to hazardous substances, indicating their nature and transport risk. Each material is then grouped by hazard class (e.g., flammable liquid) and packing group (I, II, or III), which reflects its level of danger.
- UN Number: A unique identifier for hazardous goods (e.g., UN1210 for printing ink).
- Hazard Class: Categorizes the type of risk (e.g., Class 3 for flammable liquids).
- Packing Group: Determines packaging strictness (I = high danger, II = medium, III = low).

2. Common UN Numbers for Inkjet Printer Inks
| Ink Type | UN Number | Hazard Class | Packing Group |
|---|---|---|---|
| Solvent-Based CIJ Ink | UN1210 (Printing Ink) | Class 3 (Flammable Liquid) | II or III (depends on flash point) |
| TIJ Water-Based Ink | Not classified as hazardous | N/A | N/A |
| DOD UV-Curable Ink | UN1263 (Paint Related Material) | Class 3 | III |
| Ink Solvent (e.g., MEK) | UN1193 (Methyl Ethyl Ketone) | Class 3 | II |
| Cleaning Solution | Varies by chemical base | Usually Class 3 | II or III |

3. What Determines an Ink’s Classification?
The UN classification of an ink is based on its flash point, chemical composition, vapor pressure, and toxicity. For example:
- Flash Point: If below 60°C (140°F), it’s usually classified as flammable.
- Solvent Type: Alcohols, ketones, or hydrocarbons often require Class 3 labeling.
- VOC Content: High volatile organic compound content raises hazard levels.

4. Required Documentation for Shipping
To transport ink classified under UN regulations, the following documents are typically required:
- MSDS (Material Safety Data Sheet): With UN number and hazard class.
- Dangerous Goods Declaration (DGD): For IATA or IMDG compliance.
- Proper Labeling: Includes hazard labels, UN number, and handling instructions.
- Packaging Certificates: UN-approved packaging must be used.
—
5. Packaging and Labeling Guidelines
UN-classified inks must be packaged according to strict international regulations:
- Use leak-proof, impact-resistant containers with UN certification.
- Apply appropriate hazard labels (e.g., Class 3 Flammable Liquid).
- Include orientation arrows, emergency contact numbers, and handling symbols.

6. Exceptions and Special Cases
Some TIJ or aqueous-based inks may fall under “Limited Quantity” or “Excepted Quantity” exemptions if shipped in small volumes. These exemptions ease packaging and documentation requirements but still require careful attention.

7. Risks of Non-Compliance
- Shipment Delays: Due to missing or incorrect paperwork.
- Fines and Penalties: Authorities may impose heavy fines for violations.
- Safety Hazards: Poor labeling or packaging can cause leakage, fire, or health issues.
