Commerce Department Corrects Error in Review of PET Resin Antidumping Order

Estimated reading time: 3–5 minutes

The U.S. Department of Commerce has corrected a mistake in its review of an antidumping duty order on polyethylene terephthalate (PET) resin from Oman. This resin is used to make products like plastic bottles. The review originally covered shipments from May 1, 2023, to April 30, 2024, and involved a producer and exporter, OCTAL SAOC FZC.

In an earlier report published on May 18, 2026, the Commerce Department said it had made a clerical error. The mistake involved the calculation of costs related to how long products stayed in U.S. storage. The department used the wrong numbers from OCTAL’s cost reports.

APG Polytech LLC, Indorama Ventures USA, Inc., and Nan Ya Plastics Corporation, America pointed out this mistake. After checking, the department agreed with these companies and decided to fix the mistake. Now, they will use the correct costs from the most recent database.

With the error corrected, Commerce has updated the dumping margin for OCTAL from Oman to 3.02 percent. This means the company needs to adjust the prices of its products sold in the U.S.

The Commerce Department wants to display transparency and plans to reveal the corrected calculations to involved parties within five days. They will also inform the U.S. Customs and Border Protection on how to handle duties on imports of PET resin from Oman during the review period. The department set procedures, such as how taxes should be charged when rates are not zero or almost zero.

For importers, it is crucial to submit required documents on duties before their goods from Oman are processed. Failing to do so may cause fines. Also, any private information involved in this case must be returned or destroyed as per rules to protect confidential data.

The rules on cash deposits for future shipments have changed. The rate for OCTAL will be based on the new 3.02 percent margin. For other companies involved in the production or export of the PET resin, the rate depends on specific rates from recent reviews. The standard rate stated in the original investigation is 7.62 percent.

The Commerce Department’s actions highlight its commitment to fair trade practices by ensuring proper calculations and oversight in all antidumping measures.
