HTS tariff line · chapter 29
2909.49.30
Dipentaerythritol having a purity of 94 percent or more by weight
Analysis
HTS 2909.49.30 covers dipentaerythritol having a purity of 94 percent or more by weight under heading 2909 (ethers, ether-alcohols, ether-phenols, ether-alcohol- phenols, alcohol peroxides, ether…).
Within this group the rate runs from duty-free to 5.5%. Compared with 2909.49.60 (other: other), which pays 5.5%, a misclassification either way moves the duty by 5.5 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 54.5% instead of nothing, so origin decides between free entry and a 54.5% duty.
The normal trade relations rate here is zero, shared by about 26% of the 1050 tariff lines in chapter 29, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Census statistics map these goods to NAICS 325199 (All Other Basic Organic Chemical Manufacturing), an industry of 894 US establishments employing 77,304 people. That concordance is how imports of this line are compared with US output.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
