Duty Rate (from China)
Products classified under Tariff item 2910.20.00
Electronic Grade Propylene Oxide
Ultra-high purity methyloxirane (propylene oxide) with less than 10 ppm metals, specifically formulated for semiconductor photoresist manufacturing. This separate chemically defined organic compound meets the purity standards of Chapter 29 and is classifiable under tariff item 2910.20.00 as an epoxide.
Industrial Propylene Oxide Drums
Methyloxirane (propylene oxide) packaged in 200L steel drums with a stabilizer for safe transport, used as a raw material for rigid polyurethane foam production. The added stabilizer is necessary for preservation or transport, as permitted by Chapter note 1(f), and the product remains classifiable under tariff item 2910.20.00.
Methyloxirane Bulk Chemical
Pure methyloxirane (propylene oxide) supplied in railcar quantities for chemical distribution, serving as a primary feedstock for hydroxypropyl derivatives in personal care products. This separate chemically defined epoxide is classifiable under tariff item 2910.20.00, provided it meets the purity criteria of Chapter 29.
Pharma Grade Propylene Oxide
GMP-certified methyloxirane (propylene oxide) meeting USP/EP standards for pharmaceutical intermediate synthesis, including production of epoxide hydrolase inhibitors and chiral building blocks. As a separate chemically defined organic compound, it is classifiable under tariff item 2910.20.00, provided it does not fall under a more specific heading such as pharmaceuticals.
Propylene Oxide
Methyloxirane, commonly known as propylene oxide, is a volatile, colorless liquid organic compound with a three-membered epoxide ring. It is a separate chemically defined epoxide, classifiable under tariff item 2910.20.00, and serves as a versatile intermediate in various industrial applications.
Propylene Oxide 99.9% Technical Grade
High-purity methyloxirane (propylene oxide) at 99.9% concentration, supplied in bulk for industrial synthesis, particularly in manufacturing surfactants and other derivatives. This separate chemically defined epoxide meets the requirements of Chapter 29 and is classifiable under tariff item 2910.20.00.
Propylene Oxide for Polyol Synthesis
High-grade methyloxirane specifically for alkoxylation reactions producing polyether polyols, classified under tariff item 2910.20.00 as a separate chemically defined epoxide. This product meets Chapter 29 requirements for epoxides used in polymer manufacturing.
Propylene Oxide Polymerization Inhibited
Methyloxirane with 50 ppm hydroquinone monomethyl ether inhibitor, preventing exothermic polymerization during storage and transport for the polyurethane industry. The inhibitor is added for preservation or transport, as permitted by Chapter note 1(f), and the product remains classifiable under tariff item 2910.20.00.
Propylene Oxide with Anti-Dusting Agent
Methyloxirane containing a trace anti-dusting additive for safety handling, classified under tariff item 2910.20.00 per Chapter note 1(g). This product is used in open-system manufacturing of flame retardants and pharmaceuticals, and the additive does not render it suitable for a specific use.
Stabilized Propylene Oxide ISO Tanks
Methyloxirane with added polymerization inhibitor in 20MT ISO tanks for bulk import, under tariff item 2910.20.00 per Chapter note 1(f) for stabilized products. Used in continuous production of propylene glycol and surfactants, this product is a separate chemically defined epoxide.
