How to check the anti-dumping (AD) and countervailing duties (CVD) on imported products to the United States?

Antidumping (AD) and Countervailing Duties (CVD) address unfair trade practices by providing relief to U.S. industries and workers that are “materially injured,” or threatened with injury, due to dumping or subsidization of foreign products. These duties can be imposed by filing a petition with the Department of Commerce and the United States Commission.
If you want to check whether a product is subject to anti-dumping (AD) or countervailing duties (CVD), you can use the following methods:
⭐ Go to the CBP AD/CVD Reference System website at https://trade.cbp.dhs.gov/ace/adcvd/adcvd-public/
This site lists all active anti-dumping and countervailing duty cases and provides the applicable duty rates.
You can search directly on the platform for the product you’re interested in.

⭐ Website of the International Trade Administration at https://access.trade.gov/ADCVD_Search.aspx to check for specific anti-dumping investigations.
This site allows you to check if a particular product is affected by an AD or CVD case and view detailed rulings.
Search Instructions: To get started — Enter a country — Product — Case Number — HTS Number — Commodity.
Simply input the relevant code to find the information you need.

⭐ To look up the Case Number for a specific product, visit https://search.usa.gov/search/docs?affiliate=www.usitc.gov&dc=2359&query=99038815
You can search using the product’s HS Code to check if it is involved in any anti-dumping (AD) or countervailing duty (CVD) cases.
This helps you quickly determine whether a product is subject to trade remedies.

⭐ Use the Cargo Systems Messaging Service (CSMS) to check for the latest updates at https://www.cbp.gov/trade/automated/cargo-systems-messaging-service .
CBP occasionally releases CSMS notifications that outline new or adjusted anti-dumping (AD) and countervailing duties (CVD) on specific products.

The Harmonized Tariff Schedule (HTS) primarily provides information on:
※ Base Duties (General/Column 1)
※Preferential Duties (Special/Column 1 Special)
※Additional tariffs (like those under Sections 301, 232, or 201,usually found in Chapter 99 with codes starting 9903).
※HTS does not include anti-dumping (AD) or countervailing duties (CVD).
Here’s what you need to know:
- HTS only lists base and additional tariffs (e.g., Section 301, 232).
- When searching for a 6-digit HS code, you’ll see the base tariff rate and whether the product is subject to special tariffs, but not AD/CVD rates.
- For instance, an HTS code like 99038815 belongs to Chapter 99, which covers additional tariffs (like Section 301).
AD/CVD duties are managed by the U.S. International Trade Commission (USITC) and the Department of Commerce (DOC) and apply to specific products from specific countries or producers. CBP enforces these duties based on AD/CVD investigation findings.
