Magnesium Bromide Etherate
Magnesium bromide diethyl ether complex (MgBr2·(Et2O)2) is a Grignard reagent precursor used in organic synthesis. Despite containing an organic ether component, it is classified as a chemically defined bromide of an inorganic base under tariff item 2827.59.00, as organo-inorganic compounds are excluded from Chapter 28 only if they are not mentioned in Note 2 to Chapter 28.

Import Tips & Compliance
• Confirm that the etherate complex is presented as a single chemically defined compound, not as a mixture of magnesium bromide and diethyl ether
• Provide the molecular formula and purity data to the CBSA to support classification
• Be aware that if the product is put up in measured doses for retail sale, it may fall under Section VI Note 2 and be classified elsewhere
