Pre-vulcanized Natural Rubber Latex from Mexico

This is natural rubber latex that has been pre-vulcanized with sulfur and accelerators to partially cross-link the polymer chains, making it suitable for dipping processes in glove manufacturing. It falls under HTS 4001.10.00.00 as it remains in liquid primary form per chapter notes, retaining essential character as raw material despite vulcanizing agents for prevulcanized latex. Commonly used in medical and industrial gloves.

Import Tips

Verify concentration of total solids (typically 60%) and prevulcanization degree via lab testing to confirm classification as latex, not compounded rubber

Provide certificates of analysis showing no prohibited additives like fillers or extenders beyond allowed emulsifiers per chapter note 5

Ensure proper temperature-controlled shipping to prevent coagulation; declare as UN1263 for hazmat if ammonia-preserved
