Products classified under HTS 2930.20.90.20
Zinc Diethyldithiocarbamate (ZDEC)
ZDEC is a dithiocarbamate accelerator used principally in rubber vulcanization to speed up the curing process with sulfur. As a thiocarbamate/dithiocarbamate compound under heading 2930.20, it falls into 2930.20.90.20 when primarily used in rubber processing rather than general applications. It provides excellent fast vulcanization properties for natural and synthetic rubbers.
Zinc Dibutyldithiocarbamate (ZDBC)
ZDBC serves as an ultra-accelerator in rubber compounding, particularly effective in low-sulfur systems for tire manufacturing. Classified under HTS 2930.20.90.20 as a dithiocarbamate principally used in rubber processing per Chapter 29 heading 2930.20 structure. It offers non-blooming properties ideal for high-quality rubber products.
Sodium Dibutyldithiocarbamate
This water-soluble dithiocarbamate acts as a primary accelerator and activator in latex rubber processing for dipped goods like gloves. HTS 2930.20.90.20 applies to such thiocarbamates principally used in rubber per Chapter 29 inorganic salt classification rules. It facilitates fast curing in natural rubber latex systems.
Tellurium Diethyldithiocarbamate (TDEC)
TDEC functions as a specialty ultra-accelerator providing rapid vulcanization in butyl rubber compounds for tire inner liners. As an organo-sulfur dithiocarbamate principally for rubber processing, it classifies under 2930.20.90.20 per Chapter 29 heading structure. Its tellurium content enhances curing efficiency.
Piperidinium Pentamethylene Dithiocarbamate
This delayed-action dithiocarbamate accelerator provides scorch safety in rubber extrusion processes for automotive parts. HTS 2930.20.90.20 covers such thiocarbamates principally employed in rubber vulcanization per Chapter 29 classification hierarchy. It balances processing safety with final cure speed.
Copper Dibutyldithiocarbamate
Used as an anti-oxidant and secondary accelerator in colored rubber compounds where metal staining must be avoided. This dithiocarbamate qualifies for 2930.20.90.20 as principally a rubber processing chemical under Chapter 29 organo-sulfur provisions. Provides thermal aging resistance.
Tetramethylthiuram Disulfide (TMTD)
TMTD functions as both accelerator and sulfur donor in low-sulfur rubber curing systems for belting and hose production. As a dithiocarbamate derivative principally for rubber processing, it falls under HTS 2930.20.90.20 per Chapter 29 thiocarbamate provisions.
Benzothiazyl Disulfide (MBTS)
MBTS acts as a retarder and primary accelerator in rubber compounds requiring controlled curing rates. Though benzothiazole-based, certain delayed-action forms principally for rubber classify under 2930.20.90.20 as thiuram/dithiocarbamate analogs.
N-Pentamethylenebis(N-methyl) Dithiocarbamate
Specialty accelerator for EPDM rubber weatherstrip compounds providing excellent scorch resistance. Classifies under 2930.20.90.20 as dithiocarbamate principally used in rubber vulcanization.
