Pre-vulcanized Natural Rubber Latex
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.
High Ammonia Natural Rubber Latex
Natural rubber latex preserved with high ammonia content (0.7-1.0%) to prevent coagulation during storage and transport, used in foam mattresses and carpets. Classified under HTS 4001.10.00.00 as primary liquid form with allowed preservatives that don't alter raw material character per chapter notes 1 and 5(b).
Centrifuged Natural Rubber Latex HA Type
HA (High Ammonia) type natural latex produced by centrifugation to 60% DRC, ideal for tire cord dipping and adhesive production. HTS 4001.10.00.00 applies as it's uncompounded liquid latex with minimal allowed stabilizers per chapter note 5(b).
Low Ammonia Natural Rubber Latex LA Type
LA type latex with reduced ammonia (0.2-0.4%) and secondary stabilizers for sensitive applications like condoms and balloons. Remains HTS 4001.10.00.00 as primary liquid form with permitted viscosity-control agents.
Field Latex Natural Rubber Concentrate
Fresh natural rubber latex concentrated in-field to 30-50% DRC before further processing, used in mattress foam production. Classifies under 4001.10.00.00 as primary liquid with allowed coagulants per chapter notes.
Vulcanization-Accelerated Natural Latex
Natural latex with minimal accelerators for controlled prevulcanization in surgical glove dipping lines. HTS 4001.10.00.00 per allowance for prevulcanized latex in note 5(a)(i).
