For Indian exporters
What this means for your shipments
- Your US buyer pays. The importer of record posts a cash deposit at the AD/CVD rate when the goods enter the US, on top of normal duty.
- The rate depends on who made and sold the goods. Companies reviewed by Commerce get their own rate; everyone else gets the all-others rate.
- The entry is filed differently. The customs broker files it as an AD/CVD entry and quotes the case number, so share the producer and exporter names with your buyer.
- Rates can change every year. Interested parties can ask for an administrative review in the order's anniversary month.

Questions
Hexamine from India: FAQs
Is there anti-dumping duty on hexamine from India?
Yes. Imports of hexamine from India are subject to an antidumping duty order (A-533-932, since 7 Jan 2026) and a countervailing duty order (C-533-933, since 7 Jan 2026), according to the U.S. International Trade Administration's list of orders in force as of 18 Sept 2026.
What is the duty rate on hexamine from India?
When the orders were issued, the rate for exporters not individually named (the "all-others" rate) was 5.11% (cash deposit 3.12%) for the AD order and 2.34% for the CVD order. Rates are set per producer and exporter and change after each administrative review, so the rate on a shipment today depends on who made and sold it. Check the latest Federal Register notice.
Who pays the anti-dumping duty, the Indian exporter or the US importer?
The US importer of record. It pays a cash deposit at the AD/CVD rate when the goods enter the US, and the final amount is settled when Commerce completes its review. In practice the duty shapes the price the US buyer can pay, so it matters to the Indian exporter too.
When can the orders on hexamine from India end?
Orders are reviewed every five years in a "sunset review". The next one for hexamine from India is due to start in Dec 2030. Until an order is revoked, it stays in force.
Source: U.S. International Trade Administration, "AD/CVD Orders and Suspension Agreements", and the Federal Register (as of 18 Sept 2026). Rates shown are those printed in the order notice; current rates are set by later reviews.
