Customs Clearance of Colloidal Graphics | HS Code, Documents, Permits & Key Tips

Customs Clearance of Colloidal Graphics in Iran (HS Code + Documents & Permits)

Customs clearance of colloidal graphics (Colloidal Graphics) involves a category of chemical materials with special properties that are used across a wide range of industries including paint, ink, and nanotechnology. These materials contain very fine particles that remain dispersed in liquids, which enables high performance in various industrial processes. Due to technical sensitivities and complex composition, clearing these materials from customs requires sufficient knowledge and experience with chemicals and specialty goods.

1) Industrial Applications of Colloidal Graphics

Printing & ink manufacturing: One of the main applications of colloidal graphics is in producing inks for inkjet printers. Thanks to favorable dispersion, these materials help ink spread uniformly on the print surface and deliver high quality.

Paint industry: In paint production, colloidal materials are used to increase stability and quality. They provide higher resistance to environmental factors and help maintain color quality over time.

Nanotechnology & electronics: In advanced electronic equipment and nanotechnology processes, colloidal graphics are used to create thin layers and protective coatings. Due to their small particle size, they can form very thin and precise films used in chip and advanced component manufacturing.

2) Types of Colloidal Graphics & Applications

1. Colloidal microcapsules — HS Code: 3824.90.90

Applications: Highly used in printing and inkjet ink production. They help ink spread uniformly on the print surface for high quality. Also used in pharma and cosmetics to encapsulate actives and control their release.

2. Colloidal nanostructures — HS Code: 3824.90.99

Applications: Used in nanotechnology and electronics to make thin films and anti-scratch coatings for electronic displays and advanced equipment.

3. Colloidal silicones — HS Code: 3824.90.91

Applications: Thanks to water repellency and high heat resistance, used in paints, protective coatings, and cosmetics. Also used for electrical insulation and protective coatings for industrial equipment.

4. Silver colloids — HS Code: 3824.90.92

Applications: Due to antibacterial and disinfectant properties, used in medical and hygiene industries—disinfectant drugs, hygiene products, medical equipment—as well as specialty paints and antimicrobial coatings.

5. Gold colloids — HS Code: 3824.90.93

Applications: Widely used in nanotechnology and medical sciences (biosensors, diagnostics, nano-therapies), and also in paint making and specialty inks.

6. Polymer colloids — HS Code: 3824.90.94

Applications: Used in producing paints, inks, and industrial coatings. Owing to stability and uniform distribution, polymer colloids enable high-quality, durable products.

3) Key Points for Clearing Colloidal Graphics from Iranian Customs

Technical documents: One of the first and most important steps is submitting complete and accurate documents, including import papers, technical analysis, and quality certificates. These must show chemical composition, exact quantity of each component, and relevant safety/quality approvals.

Quality-control testing: Given the sensitivity of these materials and the need for high accuracy, imports may undergo rigorous QC testing—especially for goods from countries such as Germany and Japan, known for stringent standards.

Import permits: Due to chemical nature, imports may require special permits from relevant bodies such as the Environmental Protection Organization and the Ministry of Health. Coordination with the National Standards Organization and other regulators is necessary to ensure full compliance with national laws.

4) Import & Export Conditions for Colloidal Graphics

Countries exporting to Iran: China: one of the largest suppliers, especially for nanostructures and silicone colloids. Germany: a main source for microcapsules and gold colloids. Japan: known for advanced nanostructures and colloids. United States: supplies various types including silver and polymer colloids.

Countries importing from Iran: Exports go to markets needing advanced technologies and specialty industries—Gulf countries, Turkey, and some Central Asian states. Given the specialized nature, Iran’s exports are limited and relatively small.

5) Import/Export Volumes & Global Role

Import volume: Especially in industrial and high-tech sectors, imports are rising. In recent years, imports have reached about 2,000–3,000 tons per year, varying with industrial demand and economic shifts.

Export volume: Compared to imports, exports are more limited—estimated at about 500–700 tons per year—reflecting focus on niche markets and limited global demand.

Global turnover: The global market is growing; total market value—especially in printing, nanotech, and pharma—reaches billions of dollars, driven by technological progress and growing cross-industry demand.

6) Global Exporters & Importers

Global exporters: Germany: a leading producer, especially in nanostructures and gold colloids. USA: exporter of various types including silver and polymer colloids. China: a major producer/exporter of silicone colloids and nanostructures.

Global importers: Europe: countries such as the UK, France, and the Netherlands are major importers due to advanced tech needs. East Asia: Japan and South Korea are major buyers in nanotechnology and high-tech applications.

7) Documents Required for Clearing Colloidal Graphics

To clear colloidal graphics from customs, you must provide a set of documents to ensure a correct, trouble-free process.

Commercial Invoice

Must include all product details—name, quantity, unit price, and total price. It provides key cost/terms info and helps customs determine value.

Packing List

Contains number/type of packages, dimensions and weight of each, and contents—necessary for customs inspection and to ensure correct packing.

Bill of Lading or Air Waybill

Shows transport details—mode (sea/air/road), carrier info, and destination. It evidences shipment from origin to destination.

Certificate of Origin

Confirms the exporting country and is needed for tariff determination and trade-agreement compliance.

Quality & Test Certificates

Must confirm compliance with international/national standards. For colloidal graphics, include QC test results demonstrating product quality and safety.

Special Permits

Some types may require special permits from regulators such as the Environmental Protection Organization or the Ministry of Health—confirming safety and legal compliance for specific chemicals.

Order Registration Document

Includes order number, registration date, and buyer/seller info—evidence that the order is officially registered and ready for clearance.

Approval Certificates

Typically issued by accredited labs or standards bodies, confirming conformity with relevant standards.

Proof of Duty & Tax Payment

Must show that all customs duties and taxes on the imported goods have been paid—required to complete clearance.

Customs Declaration Forms

Specific customs forms, such as the import declaration, must be completed accurately per customs instructions.

8) Best Method to Clear Colloidal Graphics in Iran

For fast, efficient clearance, follow these steps:
Prepare/submit complete documents: import permits, transport docs, safety and packaging certificates. Work with a specialist customs broker familiar with chemicals/colloids to speed the process.
Pay duties and taxes on time to avoid delays.
Follow international packaging/transport standards (UN/IMDG) appropriate to the chemical nature of the material.
