Products classified under HTS 2909.19.14.00
Methyl Tertiary-Butyl Ether (MTBE) 99% Purity
MTBE is a colorless, volatile liquid acyclic ether used primarily as a high-octane gasoline additive to boost octane ratings and reduce emissions. It falls under HTS 2909.19.14.00 as a specific ether of monohydric alcohols, chemically defined per Chapter 29 notes (a). This industrial-grade product meets purity standards for fuel blending.
Industrial MTBE Fuel Oxygenate
This MTBE variant serves as an oxygenate in reformulated gasoline to meet clean air standards, featuring precise chemical structure as 2-methoxy-2-methylpropane. Classified under HTS 2909.19.14.00 for its acyclic ether nature from monohydric alcohols. Supplied in tanker loads for refinery blending.
Refinery-Grade MTBE Octane Booster
High-purity MTBE designed for refinery use to enhance gasoline octane without aromatics, adhering to Chapter 29 scope for chemically defined acyclic ethers. HTS 2909.19.14.00 specifies this monohydric alcohol ether. Typically shipped in drums or isotanks.
MTBE Gasoline Blending Agent 98.5%
A 98.5% pure MTBE used for blending into unleaded gasoline to improve combustion efficiency, qualifying as a separate chemically defined acyclic ether under Chapter 29 note (a). Specific to HTS 2909.19.14.00 for methyl tertiary-butyl ether.
Technical Grade MTBE for Fuel Additives
Technical-grade MTBE with stabilizer for safe transport as a fuel additive precursor, still classified as pure acyclic ether per Chapter 29 notes (f) for added stabilizers. HTS 2909.19.14.00 applies to this monohydric alcohol ether.
Pure MTBE Chemical Intermediate
Ultra-pure MTBE used as a solvent or intermediate in organic synthesis, distinctly an ether of monohydric alcohols under HTS 2909.19.14.00. Meets Chapter 29 criteria for chemically defined compounds.
Stabilized MTBE for Transport
MTBE with added anti-dusting agent for safe bulk transport, allowable under Chapter 29 note (g) without changing general use classification. HTS 2909.19.14.00 for this specific ether.
MTBE 99.5% Spectroscopic Grade
Spectroscopic-grade MTBE at 99.5% purity for analytical and research applications as a solvent ether. Falls under HTS 2909.19.14.00 as chemically defined acyclic ether from monohydric alcohols.
