CBIC Imposes Anti-Dumping Duty on Potassium Tertiary Butoxide (KTB) and Sodium Tertiary Butoxide (STB) Imports from China and USA

The Ministry of Finance, Government of India, has imposed anti-dumping duties on imports of Potassium Tertiary Butoxide (KTB) and Sodium Tertiary Butoxide (STB) originating from China and the United States of America. The levy was notified via Notification No. 20/2025-Customs (ADD) dated 24th June 2025, based on final findings issued by the Directorate General of Trade Remedies (DGTR) under Notification No. 6/11/2024-DGTR.

Subject Goods and Classification

The subject goods covered are:

Potassium Tertiary Butoxide (KTB)
Sodium Tertiary Butoxide (STB)

These are vital chemical reagents widely used in organic synthesis and industrial applications. They are classified under the following tariff items of the Customs Tariff Act, 1975:

29051490
29051920
29051990
29054900

Findings of DGTR

As per the DGTR’s final findings dated 25th March 2025, it was concluded that:

The subject goods were exported to India at prices below normal value, indicating dumping.
Such dumping caused material injury to Indian producers.
There was clear evidence of price undercutting and erosion of market share by domestic players due to these low-priced imports.

Structure of Anti-Dumping Duty

Anti-dumping duty has been imposed as follows:

S. No.	Product	Country of Origin	Producer	Duty Rate (USD/MT)
1	KTB	China PR	GenChem & GenPharm	929
2	KTB	China PR	Other producers	1,710
3	KTB	USA	All producers	984
4	STB	China PR	GenChem & GenPharm	NIL
5	STB	China PR	Other producers	304

Note: The duty applies to all imports from the listed countries, including cases of trans-shipment through third countries.

Duration and Applicability

The anti-dumping duty will remain in force for five years from the date of the notification unless revoked earlier.
Duties are payable in Indian Rupees, calculated based on the prevailing exchange rate at the time of Bill of Entry filing under Section 46 of the Customs Act, 1962.

Impact and Implications

Domestic Industry:

The notification provides protection to Indian manufacturers producing these essential chemical reagents.
Helps restore fair market conditions and prevent predatory pricing tactics.

Importers and Traders:

Must recalibrate cost structures and review supplier agreements.
Imports from GenChem & GenPharm (for KTB and STB) enjoy preferential rates, offering limited relief.

Legal and Compliance Advisors:

May need to assist clients in reclassification, exemption eligibility, or explore mid-term review petitions, if applicable.

Conclusion

The imposition of anti-dumping duty on KTB and STB reaffirms India’s trade remedy mechanisms and its proactive approach in defending domestic industries from unfair pricing. For stakeholders in the chemical and pharmaceutical sectors, aligning with this regulatory change is crucial to ensure seamless compliance and business continuity.
