Import Tips

Provide detailed chemical analysis (GC-MS) confirming linear C12 chain and >98% purity to avoid reclassification as mixed alkylbenzenes

Include Safety Data Sheets (SDS) and end-use declarations specifying detergent intermediate use to comply with TSCA import requirements

Verify supplier COA matches declared CAS 123-72-8 (actually 26636-34-0 for LDB) to prevent customs holds
