Customs Clearance of Inorganic and Non-Metal Acid Esters in Iran (HS Code + Documents & Permits)
Customs clearance of inorganic and non-metal acid esters: Inorganic and non-metal acid esters are among highly important chemical components used across various industries, and due to their unique properties, they play a vital role in producing chemical, pharmaceutical, agricultural, and even food products. These chemical compounds are produced via the reaction between inorganic acids and alcohols and are used as chemical intermediates, solvents, and specialized additives in different processes. Accordingly, importing these materials—given their specific sensitivities—requires full awareness of customs laws and regulations, required documents, and the special import conditions.

Inorganic and non-metal acid esters are widely used across industries due to their specific chemical and physical properties. Some of the most important applications include:
Chemical industries: These compounds are used as raw materials in producing many chemicals, resins, plastics, and solvents. Owing to their reactivity and high stability, inorganic acid esters play a vital role particularly in industrial and specialized chemical production.
Pharmaceutical industries: In drug manufacturing, these esters act as chemical intermediates for producing active pharmaceutical ingredients. They are also used as chemical stabilizers in certain pharmaceutical formulations. For example, phosphoric acid esters are involved in producing anti-inflammatory and analgesic medications.
Agriculture: Inorganic and non-metal acid esters are used in producing pesticides and chemical fertilizers. They act as active substances in many agrochemical formulations to improve the quality and performance of crops.
Food industry: Some inorganic and non-metal acid esters—especially those with safe, non-toxic profiles—are used as approved additives in the food industry. These materials can help enhance taste, aroma, and shelf life.

2) Tariff (HS Code) & Import Conditions for Inorganic & Non-Metal Acid Esters
The tariff classification (HS Code) of inorganic and non-metal acid esters varies by type and chemical structure. Generally, these compounds are commonly classified under 29209090. This heading covers esters of inorganic acids such as sulfuric, phosphoric, and nitric acid. Chemicals under this HS are of special importance due to their wide applications in pharmaceutical and chemical industries.
| Goods | Short Description | HS Code |
|---|---|---|
| Inorganic & non-metal acid esters | Esters of sulfuric/phosphoric/nitric acids; chemical intermediates | 29209090 |
The exact final subheading depends on formulation, end-use grade, purity, and packaging.
3) Special Import/Export Conditions for Inorganic & Non-Metal Acid Esters
Due to their specific chemical characteristics, these esters play a vital role across industries; however, because of their chemical nature, special rules and conditions govern their import and export. Importers and exporters must be aware of these requirements to best manage clearance and transport.
1. Dangerous goods transport regulations
Some inorganic and non-metal acid esters fall under dangerous goods due to chemical reactivity and potential hazards. Such materials must be transported in accordance with international regulations like the IMDG Code (International Maritime Dangerous Goods Code). These rules ensure safety in dangerous-goods transport and include precise instructions for packaging, labeling, and conditions for moving hazardous chemicals.
For example, nitric or phosphoric acid esters used in chemical and pharmaceutical industries require specialized transport following these regulations. Packaging and storage must be under special conditions with controlled temperature and humidity to prevent incidents.
2. Health and standards permits
Chemicals—especially those used in food and pharmaceutical industries—require health and standards approvals from competent authorities. For imports into Iran, such permits must be obtained from bodies such as the Food & Drug Organization and the National Standards Organization of Iran. These approvals ensure the chemicals are safe and meet health/quality standards.
This is particularly critical for esters used in drug manufacturing or food additives; non-compliance can lead to clearance rejection or heavy penalties.
3. Specialized transport
Depending on the ester type, transport and storage must be carried out under specific, specialized conditions. Due to sensitive chemical properties, some require safe transport and controlled storage. To preserve quality and prevent risks, special containers and safety equipment must be used. For instance, some esters are sensitive to temperature and humidity and should be stored in fully controlled environments.

4) Main Exporter and Importer Countries for These Esters
Given their wide industrial applications, these esters are exported by industrialized, advanced countries. Key exporters include: Germany: a leading global chemical producer playing a key role in producing and exporting inorganic acid esters; German chemical companies are among the most important global suppliers due to high quality and production expertise. China: a major exporter thanks to mass production and large chemical exports—many countries, including Iran, source these from China. United States: with strong chemical infrastructure, another major exporter; U.S. companies produce high-quality esters thanks to scientific and technological advances. On the other side, key importers are countries active in chemical and pharmaceutical industries: Iran: due to significant growth in chemical, pharmaceutical, and agricultural sectors, Iran is a main importer; companies need these esters to produce chemicals and pharmaceuticals. India: a major importer for its large generics and chemical industries. Turkey: also a significant importer due to rapid growth in chemicals and pharmaceuticals.
5) Iran’s Import Volume and Global Circulation
Imports/exports of inorganic and non-metal acid esters to Iran: Owing to broad domestic industrial needs, Iran’s import volume of these esters is continuously increasing. As a principal regional consumer, Iran accounts for a significant share of imports. In recent years—particularly with the expansion of pharmaceutical and chemical industries—the need has risen. Imports mainly come from China and Germany, though sourcing from other countries is growing. Global circulation: These esters constitute a segment of global chemical trade due to wide applications.

6. Import License
Depending on the ester and its application, licenses may be needed from: the National Standards Organization (to confirm compliance with national standards); the Food & Drug Organization (for food/pharma use); and the Department of Environment (if the material may pose environmental risks).
7. Bill of Lading (B/L)
Issued by the carrier; contains ownership, mode of transport (sea/air/road), route, and carriage conditions. Essential for customs release.
8. Insurance Certificate
Confirms cargo insurance during transit, including cargo value and coverage, to mitigate potential losses.
9. Order Registration
For imports into Iran, goods must be registered in the Ministry of Industry, Mine & Trade’s ordering system. This first step enables obtaining necessary permits and beginning customs procedures.
10. Inspection Certificate
