Customs Clearance of Storage and Wall-Mounted Water Heaters in Iran (HS Code, Documents, and Permits)

Storage and wall-mounted (instant) water heaters are key equipment for hot water supply in residential, commercial, and industrial units and hold a significant share in imports of mechanical (HVAC) equipment. Due to their broad use and safety energy sensitivities, importing and clearing these items requires accurate tariff classification, obtaining permits, and submitting complete documents so the goods enter legally and quickly reach the consumer market.

1) Detailed Description of Storage and Wall-Mounted Water Heaters

Storage water heaters, with a storage tank, keep water at a target temperature and are stable options for high-peak demand (hotels, pools, large offices, and complexes). Their main advantage is continuous hot water supply; in contrast, they have higher standby energy consumption and require a larger installation area.

Wall-mounted (instant) water heaters, without a tank and only heating when used, offer compact size, easy installation, better energy efficiency, and suitability for apartments. Depending on the model, they can be installed indoors or outdoors. Both groups can be electric or gas-fired and must meet safety requirements (stable flame, temperature and pressure sensors, ventilation) and energy labeling.

2) Types and Applications

3) Key Points in Customs Clearance

• Energy efficiency: Wall-mounted instant heaters optimize energy by heating water only when needed, cutting energy bills and helping the environment. Storage heaters, while ensuring continuous hot water, may have higher energy use due to standby losses.
  Ease of installation and maintenance: Instant heaters are easier to install due to smaller size and weight; they need little space and can be installed in places like kitchens or bathrooms. Storage heaters require larger space (e.g., utility rooms) and may incur higher maintenance costs, especially with periodic servicing.
  Continuous hot water supply: Storage heaters can supply large volumes of hot water continuously a key advantage for hotels, pools, and complexes. They may use electric or gas heating systems.
• Compliance with national and international standards: Because they involve water and energy, heaters must meet defined safety and quality standards. Iran National Standards Organization closely supervises these products; importers must present national conformity certificates covering safety, energy consumption, performance, and materials.
  
  Currency allocation and financing: In some cases, heaters are treated as essential goods and may qualify for governmental or NIMA FX allocation. Allocation depends on market needs and the product’s importance; importers must provide supporting documentation. This can materially impact final landed costs. If using subsidized FX, all legal requirements and documents must be properly submitted.

4) Customs Tariff / HS Code

Accurate tariff classification is one of the most important steps in clearance. Storage and wall-mounted heaters are commonly classified under HS 8419.11.00 (for gas instant heaters) and other related codes for gas/other energy types, while electric water heaters are generally under 8516.10.xx. Knowing the correct HS for each type matters because it directly affects import costs and may vary by country of origin and energy source.

Important: In many classification systems, electric water heaters fall under Chapter 85, heading 8516.10, while 8419.11 is usually for gas instant heaters. Final HS must be determined based on the product’s actual specs and the latest Iran tariff edition.

5) Special Conditions for Import and Export

• Storage and wall-mounted heaters are mainly imported to Iran from China, Türkiye, Germany, and Italy—major producers of these devices. Conversely, Iran-made heaters are exported to neighboring countries such as Iraq and Afghanistan and some African countries. Competitive pricing and acceptable quality create strong opportunities to grow exports.

6) Iran Market

Imports mainly come from China, Türkiye, Germany, and Italy. Domestic production is exported to Iraq, Afghanistan, and some African countries. Domestic demand grows with construction activity and facility upgrades.

7) Trade Volume

Import volumes of water heaters to Iran are significant due to market needs and the construction boom. With rising demand in neighboring countries, exports have also increased. Globally, China is the largest exporter, while the US and European countries are among the largest importers.

8) Global Market

• Major exporters: China, Türkiye, Germany, Italy
• Major importers: United States and European countries

9) Required Documents for Clearance

• Proforma Invoice: Preliminary purchase document with full details of seller, buyer, item, quantity, price, and delivery terms.
  Commercial Invoice: Final document with price, payment terms, seller/buyer details, and precise item description.
  Bill of Lading (B/L): Transport document including carrier, origin/destination, weight, and volume.
  Certificate of Origin (CO): Issued by the origin country’s Chamber of Commerce, identifying the producing country often needed for tariff preferences.
  Packing List: Package details, number of packages, net/gross weights, and dimensions.
  National Conformity Certificate: Issued by Iran National Standards Organization confirming compliance with national standards and safety requirements.
  Pre-shipment Inspection (PSI) Certificate: In some cases required; confirms quality and quantity by an independent inspection company before dispatch.
  Order Registration License: Issued by Iran’s Ministry of Industry, Mine and Trade (MoIMT) and required for imports.
  Health & Safety Certificate: If heaters require sanitary/safety confirmation, obtain from competent authorities.
  Customs Declaration: Prepared by the importer; includes complete information about the goods, value, weight, and tariffs basis for customs calculation.
  Currency Allocation Certificate: If governmental/NIMA FX is used, provide the certificate from the Central Bank or the issuing bank.
  Proper, accurate preparation and submission of these documents is critical to avoid delays and issues during clearance.

Key Tips and Practical Recommendations

• Finalize HS based on the energy source and installation type.
• For gas-fired models, specify ventilation and flue/combustion chamber safety in the documentation.
• Attach the energy label and performance/efficiency certificate to the file.
