HS Code:
1,6-Diisocyanatohexane; 2,4-diisocyanato-1-methylbenzene polymer (CAS No. 26426-91-5) in n-butyl acetate, classified under HS subheading 3911.90.45, is a type of polyurethane prepolymer used primarily in the production of coatings, adhesives, sealants, and elastomers. This chemical compound is valued for its reactivity and ability to form durable, flexible, and resistant materials, making it a critical component in industries such as automotive, construction, and manufacturing. It is often dissolved in n-butyl acetate, a solvent that enhances its applicability in industrial processes.

Growing demand in automotive coatings
Increased trade volume due to rising production of vehicles requiring durable and weather-resistant coatings, especially in Asia-Pacific and Europe.
2021-2023
Shift towards eco-friendly alternatives
Pressure on manufacturers to develop low-VOC (volatile organic compound) formulations, potentially reducing demand for solvent-based products like those in n-butyl acetate.
2022-2023
Rising raw material costs
Fluctuations in the price of petrochemical derivatives used in production have led to higher costs, impacting profit margins for exporters.
2022
The European Union introduced stricter exposure limits and mandatory training for workers handling diisocyanates, including 1,6-diisocyanatohexane derivatives, to reduce health risks.
August 2023
Increased compliance costs for exporters to the EU market, potentially reducing trade volume in the short term but ensuring long-term safety standards.
A new bilateral agreement reduced tariffs on certain chemical products, including polyurethane prepolymers, facilitating smoother trade between the two countries.
March 2023
Boosted export opportunities for US manufacturers to China, likely increasing trade volume by 5-10% in the next year.
Several leading chemical companies announced research breakthroughs in bio-based alternatives to traditional isocyanate polymers, aiming to reduce reliance on petrochemicals.
June 2023
Potential shift in market dynamics as sustainable alternatives gain traction, possibly affecting demand for conventional products under HS 3911.90.45.
