MTBE is an acyclic ether produced from methanol and isobutylene, widely used as a gasoline oxygenate additive. It is a chemically defined compound under Chapter 29 Note 1(a) and falls under tariff item 2909.19.00 as an 'other' acyclic ether.
Methyl Tertiary-Butyl Ether (MTBE) 99% Purity
Methyl tertiary-butyl ether (MTBE) at 99% purity is a colorless, volatile acyclic ether used as a high-octane gasoline additive. It qualifies under tariff item 2909.19.00 as an 'other' acyclic ether, being a separate chemically defined compound per Chapter 29 Note 1(a).
MTBE 99.5% Spectroscopic Grade
Spectroscopic-grade MTBE at 99.5% purity is a chemically defined acyclic ether used as a solvent in analytical and research applications. It falls under tariff item 2909.19.00 as an 'other' acyclic ether, consistent with Chapter 29 Note 1(a) for separate chemically defined organic compounds.
MTBE Gasoline Blending Agent 98.5%
This 98.5% pure MTBE is used for blending into unleaded gasoline to improve combustion efficiency. It qualifies as a separate chemically defined acyclic ether under Chapter 29 Note 1(a) and falls under tariff item 2909.19.00 as an 'other' acyclic ether.
Pure MTBE Chemical Intermediate
Ultra-pure MTBE used as a solvent or intermediate in organic synthesis is a chemically defined acyclic ether. It meets Chapter 29 criteria for separate chemically defined compounds and is classified under tariff item 2909.19.00 as an 'other' acyclic ether.
Refinery-Grade MTBE Octane Booster
Refinery-grade MTBE is a high-purity acyclic ether designed to enhance gasoline octane without aromatics. It adheres to Chapter 29 scope for chemically defined acyclic ethers and is classified under tariff item 2909.19.00 as an 'other' acyclic ether.
Stabilized MTBE for Transport
Stabilized MTBE for transport contains an added anti-dusting agent, which is allowable under Chapter 29 Note 1(g) as long as it does not render the product suitable for a specific use. It remains classified under tariff item 2909.19.00 as an 'other' acyclic ether.
Technical Grade MTBE for Fuel Additives
Technical-grade MTBE with a stabilizer for safe transport is classified as a pure acyclic ether per Chapter 29 Note 1(f) for added stabilizers. It falls under tariff item 2909.19.00 as an 'other' acyclic ether, provided the stabilizer is necessary for preservation or transport.
