Methacrylic Acid/Maleic Acid Copolymer Solution
Methacrylic acid with MEHQ inhibitor is methacrylic acid containing monomethyl ether hydroquinone (MEHQ) at 100-400 ppm to prevent polymerization. Chapter 29 note 1(f) permits added stabilizers for preservation or transport, so this product falls under tariff item 2916.13.00. It is a standard industrial grade for safe bulk transport.
