Products classified under Tariff item 4001.10.00
Adhesive-Grade Natural Rubber Latex
Adhesive-grade natural rubber latex is a liquid primary form of natural rubber, formulated with tackifiers that remain within the limits permitted for raw material classification. It retains its essential character as a raw natural rubber latex, suitable for use in water-based adhesives and pressure-sensitive tapes.
Balloon-Grade Natural Latex
Balloon-grade natural latex is a fine-particle natural latex concentrate used for producing party and latex balloons. It includes optical brighteners solely for identification purposes, which are permitted under Chapter 40 Note 5, and remains in a liquid primary form.
Carpet Backing Latex
Carpet backing latex is natural rubber latex used to impregnate tufted carpet backings. It is a liquid primary form of natural rubber, uncompounded with any additives beyond those permitted for raw material classification, and is intended for further processing.
Centrifuged Natural Rubber Latex HA Type
Centrifuged natural rubber latex HA type is a high-ammonia latex concentrated by centrifugation to 60% dry rubber content. It is an uncompounded liquid primary form with minimal allowed stabilizers, making it suitable for tire cord dipping and adhesive production.
Condom Manufacturing Latex
Condom manufacturing latex is an ultra-low protein natural latex used for producing barrier condoms. It is a raw, uncompounded liquid primary form of natural rubber, with only minimal additives for stabilization and preservation, and is intended for further processing.
Field Latex Natural Rubber Concentrate
Field latex natural rubber concentrate is fresh natural latex concentrated in-field to 30-50% dry rubber content before further processing. It is a liquid primary form with allowed coagulants, used in mattress foam production, and retains its raw material character.
Foam-Grade Natural Rubber Latex
Foam-grade natural rubber latex is specially stabilized natural latex for producing latex foam rubber in upholstery and bedding. It is an uncompounded liquid primary form with permitted foaming agents, retaining its raw character for further processing.
High Ammonia Natural Rubber Latex
High ammonia natural rubber latex is preserved with 0.7-1.0% ammonia to prevent coagulation during storage and transport. It is a liquid primary form of natural rubber, uncompounded with any additives beyond preservatives, and is used in foam mattresses and carpets.
Industrial Glove Dipping Latex
Industrial glove dipping latex is heavy-duty natural latex for chemical-resistant work gloves, and may be prevulcanized for thickness. As prevulcanized latex is explicitly included in the tariff item, it remains a liquid primary form of natural rubber.
Low Ammonia Natural Rubber Latex LA Type
Low ammonia natural rubber latex LA type has reduced ammonia (0.2-0.4%) with secondary stabilizers for sensitive applications like condoms and balloons. It remains a liquid primary form with permitted viscosity-control agents, retaining its raw character.
Mattress Foam Natural Latex
Mattress foam natural latex is stabilized natural latex for Dunlop or Talalay mattress foam production. It is a liquid primary form with emulsifiers, which are permitted under Chapter 40 Note 5, and retains its essential character as a raw material.
Medical Glove Dipping Latex
Medical glove dipping latex is high-purity, low-antigen natural latex for powder-free medical examination gloves via ceramic former dipping. It is a prevulcanizable primary form, uncompounded with any additives beyond those permitted for raw classification.
Pre-vulcanized Natural Rubber Latex
Pre-vulcanized natural rubber latex is natural latex that has been partially cross-linked with sulfur and accelerators for dipping processes in glove manufacturing. It is explicitly included in the tariff item as 'whether or not pre-vulcanized' and remains a liquid primary form.
Tire Cord Dipping Latex
Tire cord dipping latex is RFL-compatible natural latex for tire cord adhesion. It is a raw liquid primary form, uncompounded with any additives beyond those permitted for raw material classification, and is used in tire manufacturing processes.
Vulcanization-Accelerated Natural Latex
Vulcanization-accelerated natural latex contains minimal accelerators for controlled prevulcanization in surgical glove dipping lines. It is a liquid primary form, and the accelerators are permitted under Chapter 40 Note 5 for prevulcanized latex, retaining its raw character.
