Bis(2-Ethylhexyl) Phthalate (DEHP)
Bis(2-ethylhexyl) phthalate (DEHP), also known as dioctyl phthalate (DOP), is a branched-chain dioctyl orthophthalate used primarily as a plasticizer for flexible PVC products. It is a separate chemically defined organic compound falling under tariff item 2917.32.00, which covers dioctyl orthophthalates, and is the principal commercial form of this ester.
2917.32.00Dioctyl Orthophthalate Stabilized Grade
Dioctyl orthophthalate stabilized grade is industrial-grade dioctyl orthophthalate with added epoxidized soybean oil stabilizer, used to enhance PVC processing stability. Under Chapter 29 Note 1(f), the added stabilizer is necessary for preservation or transport and does not render the product particularly suitable for a specific use, so it remains classifiable under tariff item 2917.32.00.
2917.32.00Dioctyl Phthalate (DOP)
Dioctyl phthalate (DOP), chemically bis(2-ethylhexyl) phthalate, is the most common dioctyl orthophthalate used as a plasticizer for PVC. It is a derivative of orthophthalic acid (1,2-benzenedicarboxylic acid) and falls under tariff item 2917.32.00, which specifically covers dioctyl orthophthalates.
2917.32.00DOP Plasticizer Technical Grade
DOP plasticizer technical grade is technical-grade dioctyl orthophthalate meeting ASTM D1045 standards for general PVC plasticizing. It is a separate chemically defined compound and is classified under tariff item 2917.32.00, as the dioctyl orthophthalate molecule is the dominant component and the product meets the Chapter 29 criteria for chemically defined organic compounds.
2917.32.00High-Purity Dioctyl Phthalate 99.5%
High-purity dioctyl phthalate 99.5% is ultra-high purity dioctyl orthophthalate used for medical-grade PVC and sensitive electronics applications. It is a separate chemically defined organic compound with a purity of 99.5% minimum, and it falls squarely under tariff item 2917.32.00 as a dioctyl orthophthalate per Chapter 29 Note 1(a).
