Related Products under Tariff item 2917.37.00
Dimethyl Terephthalate Anti-Dusting Grade
Dimethyl terephthalate in powder form with an added anti-dusting agent, included to facilitate safe handling and identification per Chapter 29 Note 1(g). The additive does not render the product suitable for a specific use, so it remains classified as dimethyl terephthalate under tariff item 2917.37.00.
DMT Flakes for Polyester Staple Fiber
Large-flake dimethyl terephthalate optimized for staple fiber melt spinning processes. The physical form and process optimization do not change the chemical identity, so it remains classified as dimethyl terephthalate under tariff item 2917.37.00.
DMT for Bottle-Grade PET Production
Premium dimethyl terephthalate specification for bottle-grade PET production, with low acetaldehyde potential. This is still chemically defined dimethyl terephthalate, and the specification does not change its classification under tariff item 2917.37.00.
DMT with Stabilizer for Long-Haul Transport
Dimethyl terephthalate with an added phenolic antioxidant stabilizer for preservation during long-haul transport. The stabilizer is necessary for preservation and does not make the product suitable for a specific use, so it is classified under tariff item 2917.37.00 per Chapter 29 Note 1(f).
High-Purity DMT for Thin Film Applications
Ultra-high purity dimethyl terephthalate for PET film production, with low oligomer content. The high purity and specific application do not change the chemical definition, so it is classified under tariff item 2917.37.00.
Industrial Grade DMT for PET Resin Production
Industrial grade dimethyl terephthalate for PET resin manufacturing via melt-phase polymerization. This is a chemically defined aromatic polyester monomer, classified under tariff item 2917.37.00.
