Hydroxides Customs Clearance in Iran (HS Codes + Documents & Permits)

Hydroxides customs clearance — Hydroxides: essential chemical compounds in multiple industries. Hydroxides are an important group of chemical compounds composed of a hydroxide group (OH) bonded to a cation, usually metallic. They are used across a wide range of industries such as chemicals, construction, water treatment, detergents, pharmaceuticals, and agriculture. Due to their high importance in industrial and manufacturing processes, clearing these materials through customs requires accuracy and specialized knowledge.

1) Structure and Importance of Hydroxides

Hydroxides are compounds formed by bonding a hydroxide group to a metal or non-metal cation. They are generally divided into two groups:

Metal hydroxides: including sodium hydroxide, potassium hydroxide, and calcium hydroxide—strong alkalis used in many industrial processes.

Non-metal hydroxides: such as ammonium hydroxide, used in agriculture, pharmaceuticals, and food production.

2) Broad Applications of Hydroxides

Owing to their chemical and physical properties, hydroxides have numerous applications: Chemical industry: NaOH and KOH are feedstocks for soaps, detergents, and many reactions. Construction: Ca(OH)₂ is used to make cement and mortar, and for pH control in water treatment. Pharma & agriculture: Hydroxides play key roles in drug manufacture and fertilizers.

Detailed Industrial Applications

  • Sodium hydroxide: a strong alkali used in soaps, detergents, paper, and textiles; also used in water & wastewater treatment, pulp production, and the food industry.
  • Calcium hydroxide: a.k.a. hydrated lime, used in construction (cement/mortar), water treatment (pH adjustment), and agriculture (soil improvement).
  • Potassium hydroxide: used in electrolyte batteries, liquid soaps, and as a catalyst in chemical/pharma processes; also used in agriculture as a potassium source.

3) Key Points for Hydroxides Clearance in Iran

Customs tariff / HS Code: Each hydroxide has a specific HS code that must be precisely identified. For example:
• Sodium hydroxide: HS 2815.11.00
• Calcium hydroxide: HS 2825.90.10
• Potassium hydroxide: HS 2815.20.00 Choosing and applying the correct code is critical to avoid clearance issues.

Product Short description HS Code
Sodium hydroxide Strong alkali; detergent & paper feedstock 2815.11.00
Potassium hydroxide Battery electrolyte; liquid soap 2815.20.00
Calcium hydroxide Hydrated lime; construction & water treatment 2825.90.10

Precise classification may vary by concentration, form (solid/liquid), purity, and industrial use.

4) Required Documents & Evidence

Required documents for clearing hydroxides include: Electronic customs declaration, Bill of Lading, Commercial Invoice, Certificate of Origin, Chemical analysis certificate to confirm quality/purity, and necessary permits where applicable (e.g., Department of Environment for hazardous chemicals).
Special conditions: Certain hydroxides, due to corrosivity/reactivity, may require permits from bodies such as the Department of Environment, Ministry of Health, and—in specific cases—the Atomic Energy Organization.

5) Best Practices & Order Registration

To speed up clearance, use the National Trade System for electronic order registration and declarations. Working with professional customs brokers helps reduce lead time and avoid issues.

6) Import Origins & Export Destinations

Hydroxides are mainly imported into Iran from China, India, the United States, Germany, and Japan. Iran may export certain hydroxides in limited volumes to neighboring countries.

7) Safety, Packaging & Compliance

  • Alkali-resistant packaging, GHS/CLP labeling, and including an up-to-date MSDS with the shipment are recommended.
  • Observe UN/ADR rules for corrosive/reactive substances during transport.
  • Align technical details across invoice and analysis sheet with the declaration to prevent misvaluation/misclassification.

Frequently Asked Questions

What are common HS codes for hydroxides?

Typically 2815.11.00 for sodium hydroxide, 2815.20.00 for potassium hydroxide, and 2825.90.10 for calcium hydroxide; final classification depends on purity, form, and end use.

Which documents are required for clearance?

Electronic declaration, Bill of Lading, Commercial Invoice, Certificate of Origin, Chemical analysis certificate, and where applicable, environment/health permits. For specific substances, permits from relevant authorities are mandatory.

How does order registration in the National Trade System help?

It standardizes processes, enables required permits, and reduces delays while aligning documents with regulations.

Are there specific safety rules for transporting hydroxides?

Yes. Use alkali-resistant packaging, GHS labeling, carry an MSDS, and follow transport regulations for corrosive/reactive substances.

How long does clearance take?

It varies by document completeness, permits, and customs office. With a complete file and prior coordination, the timeline is significantly reduced.
