Import Tips & Compliance
• Confirm the purity level (99%) and provide a certificate of analysis on shipping documents
• Ensure the product is labeled as maleic acid (CAS 110-16-7) for customs clearance
• If used in resin production, verify any environmental regulations for industrial chemicals

Adipic Acid Peroxide Derivative
Di(1-hydroperoxy-1-methylbutyl) peroxide is a peroxyacid derivative of adipic acid, an acyclic polycarboxylic acid. It is used as a polymerization initiator in rubber and plastics. This product falls under tariff item 2917.19.00 as an 'Other' derivative of acyclic polycarboxylic acids.
Anti-Dusting Fumaric Acid with Colorant
Fumaric acid with trace blue colorant and anti-dust agent for safety identification during handling. Chapter 29 Note 1(g) permits such additions for safety reasons, provided they do not render the product particularly suitable for specific use. Classified under 2917.19.00.
Aromatic-Derived Fumaric Acid
Fumaric acid produced through chemical processes involving aromatic hydrocarbons like benzene or toluene derivatives, used primarily in resins and polymer production. This acyclic polycarboxylic acid falls under tariff item 2917.19.00 as an 'Other' acyclic polycarboxylic acid, regardless of the aromatic derivation of the feedstock.
Benzene Process Fumaric Acid
Fumaric acid isolated from benzene partial oxidation routes, primarily for unsaturated polyester resin manufacture. The aromatic hydrocarbon derivation is confirmed by carbon isotope analysis, but the product itself is a chemically defined acyclic polycarboxylic acid classifiable under 2917.19.00.
Coal Tar Fumaric Acid Derivative
Fumaric acid extracted from coal tar light oil fractionation and oxidation, a traditional aromatic source for specialty resins. Despite the aromatic origin, the final product is a chemically defined acyclic polycarboxylic acid falling under 2917.19.00.
Cumene Oxidation Fumaric Byproduct
Fumaric acid recovered from cumene (isopropylbenzene) oxidation process streams, repurposed for polymer applications. The aromatic derivation via cumene does not affect the classification of the final chemically defined product under 2917.19.00.
