1. Construction Industry
Sealing window and door joints: Silicone and acrylic sealants are ideal due to their flexibility and high weather resistance. By preventing water, wind, and cold from entering, they help maintain indoor temperature and improve building energy efficiency.
Sealing exterior façades: Exposed to rain, wind, and temperature changes, façades require protection. Silicone and polyurethane sealants are used for sealing and protecting façades, helping prevent water ingress and reducing maintenance costs.
Insulating concrete and metal structures: In concrete and metal structures, polyurethane and butyl sealants fill joints between structural components. By reducing water and moisture ingress, they prevent corrosion and rusting, thereby increasing structural strength and longevity.
2. Automotive Industry
Sealing glass and doors: Polyurethane and silicone sealants are used to seal vehicle windows and doors, reducing water and dust ingress, preserving comfort and safety, and preventing unwanted wind noise.
Insulating body sections: Sealants insulate areas such as the hood, trunk, and doors. Owing to high resistance to impact, chemicals, and temperature fluctuation, polyurethanes are widely used, helping maintain body integrity and increase durability.
Vibration and noise reduction: Applied at engine–chassis interfaces and other joints, sealants help reduce vibration and cabin noise, improving ride quality and passenger satisfaction.
3. Aerospace Industry
Sealing aircraft parts and joints: Silicone and fluorosilicone sealants withstand high pressures, extreme temperature swings, and solar radiation; they help prevent air leaks and maintain cabin pressure, ensuring safety and efficiency.
Sealing fuselage and wing seams: Aerospace-grade sealants must tolerate dynamic pressure and abrupt temperature changes to prevent moisture ingress, icing, and damage, thus preserving aircraft safety.
Protection against solar radiation and chemicals: Aerospace sealants must resist fuels and industrial fluids as well as UV exposure—key to extending component life and preventing premature degradation.
4. Marine Industries
Sealing hulls of ships and boats: Butyl and polysulfide sealants offer excellent water and weather resistance, sealing hull seams to prevent water ingress and increase vessel safety and service life.
Protecting marine structures: For piers, marine bridges, and offshore platforms, polyurethane and polysulfide sealants are used owing to their resistance to corrosion, chemicals, and tough environments.
Preventing biofouling: Marine sealants must resist algae and other bio-growth to avoid performance loss and reduce maintenance costs.
2) Types of Sealants and Their Technical Characteristics
1. Silicone Sealants
Applications: Widely used in construction, electronics, automotive, and aerospace—ideal for sealing windows, doors, façades, moisture-sensitive electronics, and aircraft components.
2. Acrylic Sealants
Applications: Construction and interior finishing; sealing around windows/doors, wall and ceiling cracks, and interior trims.
3. Polyurethane Sealants
Applications: Sealing joints in large infrastructure (bridges, tunnels, concrete/steel structures) and in automotive glazing/body sections.
4. Butyl Sealants
Applications: Ideal for underground structures, ship/boat hulls, and marine structures—perform well in high-humidity and severe weather.
3) Customs Tariff and HS Codes for Sealants
HS 321410: Water-based sealants, largely used in construction and interior finishing.
HS 321490: Other sealants and similar materials used in industries including automotive, aerospace, and marine.
Customs duties vary by product type and country of origin, typically in the 10%–20% range and subject to regulatory changes.
| Product | Short Description | HS Code |
|---|---|---|
| Water-based sealant | Construction/interior sealant | 321410 |
| Other sealants and caulks | Industrial/automotive/marine | 321490 |
Final classification depends on base chemistry, grade, packaging, and end use.
4) Specific Conditions for Importing & Exporting Sealants
Environmental standards: Some sealants contain chemicals subject to environmental oversight. Importers must ensure compliance with applicable environmental standards.
Health and technical permits: For sealants intended for sensitive sectors (pharma, food, sanitary), health/technical approvals from competent authorities may be required.
Labeling and packaging: Sealants must comply with international packaging and labeling standards, including chemical composition, manufacture/expiry dates, and safety warnings.
5) Exporting/Importing Countries and Trade Volume
Importers: Iran, Türkiye, India, and several Middle-Eastern countries are major importers. Growing construction and automotive sectors in these markets are driving demand.
