What Are Anti-Dumping and Countervailing Duties?
If you import goods into the United States, two sets of additional duties can blindside you: anti-dumping duties (ADD) and countervailing duties (CVD). They are separate legal mechanisms, but they often apply together and they are both devastating if you didn't price them into your landed cost.
Anti-dumping duties are imposed when foreign manufacturers sell goods in the U.S. at prices below their home-market cost of production. The duty is designed to close that gap.
Countervailing duties are imposed when a foreign government subsidizes its domestic manufacturers — through cheap loans, free land, tax exemptions, or direct cash — giving them an unfair price advantage over U.S. producers.
Both are authorized under the Tariff Act of 1930, administered by the U.S. Department of Commerce (DOC) and the U.S. International Trade Commission (ITC), and enforced at the border by U.S. Customs and Border Protection (CBP) under 19 CFR Part 351.
Neither of these duties has anything to do with Section 301 tariffs or standard HTSUS column 1 rates. They stack on top of everything else you're already paying.
Why This Matters More Than You Think
ADD/CVD orders are not minor line items. Here are real numbers from active orders:
- Steel wire hangers from China: ADD rate up to 187%
- Wooden bedroom furniture from China: ADD rates ranging from 7% to 216% depending on the specific exporter
- Solar cells from China: Combined ADD + CVD rates exceeding 240% for certain manufacturers
- Honey from Argentina: ADD rate of 60%
- Mattresses from multiple countries: ADD rates between 18% and 1,732% — that last number is not a typo
These aren't hypothetical. If your supplier is covered by one of these orders and your broker files an entry without flagging it, CBP will bill you for the duties — often months or years later, with interest.
How ADD/CVD Orders Work in Practice
The Investigation Process
An ADD/CVD case begins when a U.S. domestic industry files a petition with Commerce and the ITC. Commerce investigates whether dumping or subsidization is occurring and by how much. The ITC determines whether U.S. industry is materially injured.
Investigations typically take 12 to 18 months. During that period, provisional measures — cash deposits — can be required as early as 90 days into the process. This means orders can start costing you money before they're even finalized.
Cash Deposits vs. Final Assessed Duties
Here's the part most importers miss: the rate you pay as a cash deposit at entry is not necessarily your final liability.
ADD/CVD are subject to annual administrative reviews conducted by Commerce. During a review, Commerce recalculates the actual dumping margin for the review period. If the final calculated rate is higher than what you deposited, CBP will issue a bill for the difference — sometimes 2 to 3 years after your shipment cleared customs.
This is called retroactive liability. It's legal, it's common, and it has put importers out of business.
Country-Wide vs. Exporter-Specific Rates
ADD orders assign rates at the exporter or producer level, not just by country. This matters enormously.
If your specific Chinese supplier was separately reviewed by Commerce and received a 0% rate, you owe nothing — even if the country-wide rate is 200%. Conversely, if your supplier never participated in a review, they likely fall under the "all others" rate or the punitive "China-wide" rate, which can be the highest number on the order.
Always verify: which rate applies to your specific supplier, not just the product category.
How to Check If Your Product Is Covered
Step 1: Search the ITC's ADD/CVD Portal
Go to dataweb.usitc.gov and use the ADD/CVD search tool. You can search by country of origin, HTSUS code, or product description. There are currently over 500 active ADD/CVD orders covering goods from more than 40 countries.
Step 2: Check the Federal Register
Every ADD/CVD order is published in the Federal Register with the exact HTSUS subheadings it covers, the covered countries, and the applicable rates by exporter. Search federalregister.gov for the specific order.
Critical caveat: HTSUS codes in an ADD/CVD order are a guide, not a guarantee. Coverage is determined by the scope language in the order — a written description of exactly what goods are covered. CBP can find your product is within scope even if your HTS code differs from those listed.
Step 3: Request a Scope Ruling
If you're genuinely unsure whether your product falls within an order's scope, you can request a scope ruling from Commerce under 19 CFR § 351.225. Commerce will issue a formal determination. This takes roughly 45 days for an informal ruling or up to 120 days for a full formal ruling.
Do this before you import at scale. A scope ruling that confirms your product is out of scope is protection against future CBP challenges.
Step 4: Check Your Supplier's Rate
Once you've confirmed the order covers your product, go to Commerce's Enforcement and Compliance website (enforcement.trade.gov) and look up the specific ADD/CVD order. Find your supplier's name in the rate table. If they're not listed individually, assume they fall under the highest "all others" or country-wide rate until proven otherwise.
Common Scenarios Where Importers Get Caught
Scenario 1: Country-Switching Without Analysis
A brand shifts production from China to Vietnam to escape Section 301 tariffs. Smart move — unless the product is also covered by an ADD/CVD order that includes Vietnam. Mattresses, for example, have ADD orders covering China, Cambodia, Indonesia, Malaysia, Serbia, Thailand, Turkey, and Vietnam simultaneously. Switching countries doesn't automatically solve an ADD problem.
Scenario 2: Third-Country Transshipment
Routing goods through a third country (e.g., China → Malaysia → U.S.) to avoid ADD/CVD is illegal. CBP actively investigates transshipment under 19 CFR § 351.225 and through the Enforce and Protect Act (EAPA). Penalties include seizure, back duties on all related entries, and potential criminal referral. Don't do it.
Scenario 3: Minor Modifications to Evade Scope
Some manufacturers slightly alter a product to argue it falls outside the order's scope. CBP and Commerce have seen every variation of this. If the modification is commercially meaningless — changing a panel thickness by 1mm, adding a minor component — Commerce will likely find it still within scope. These "circumvention" determinations are specifically authorized under 19 USC § 1677j.
Scenario 4: Buying from a Middleman, Not the Factory
If you buy from a trading company rather than the actual manufacturer, the goods may be attributed to a different exporter rate than you expected. In some cases, the trading company's rate applies; in others, the underlying factory's rate applies. This must be clarified with your customs broker before entry.
What To Do If You're Already Importing an Affected Product
Option 1: Verify and Accept
If the rate for your specific supplier is low (under 5%), the math may still work. Get written confirmation of the rate, factor it into your landed cost model, and set aside reserves for potential rate changes after administrative reviews.
Option 2: Request an Administrative Review
If your supplier has never been individually reviewed by Commerce, they can request their own administrative review during the annual review initiation window (typically in January and July each year). A successful review can establish a lower exporter-specific rate. This takes 12–18 months and requires a U.S. attorney or trade specialist. It's expensive, but the economics can justify it at sufficient import volume.
Option 3: Evaluate Alternative Suppliers or Countries
Not all countries are subject to the same orders. If steel wire hangers from China carry 187% ADD, but hangers from Bangladesh have no order in place, that's worth examining — provided the Bangladesh supplier meets your quality and capacity requirements and the product genuinely originates there under CBP's substantial transformation standard.
Option 4: Negotiate the Duty Into Your Supplier Price
In some high-volume relationships, suppliers will absorb a portion of the ADD/CVD cost to retain business. This requires leverage and a long-term relationship. It doesn't eliminate your liability — you're still the importer of record — but it can offset the landed cost increase.
The Bonding and Cash Flow Problem
One often-overlooked issue: CBP requires a continuous bond sized to cover your ADD/CVD exposure. The standard bond calculation (typically 10% of duties paid in the prior year) can fall short when ADD rates spike. CBP can demand a single-transaction bond for each shipment, or require you to increase your continuous bond significantly.
For a mid-sized importer bringing in $2 million of goods subject to a 100% ADD rate, the duty exposure is $2 million. Your bond needs to reflect that. Bond insufficiency can cause entry holds and delays at the port.
Work with your surety provider and customs broker to model this before your first ADD/CVD shipment arrives.
Final Checklist Before Your Next Import
- Searched ITC dataweb for active ADD/CVD orders on your HTS code and country of origin
- Read the scope language of any applicable order, not just the HTS codes listed
- Confirmed your specific supplier's rate on enforcement.trade.gov
- Verified your supplier is the actual manufacturer (not a trading company masking a different factory)
- Factored ADD/CVD cash deposit rates into your landed cost model
- Set aside reserves for potential retroactive duty bills from annual reviews
- Confirmed your continuous bond is sized appropriately
- Consulted a licensed customs broker or trade attorney if any of the above is unclear
ADD/CVD orders are not going away. Commerce initiates new ones every year, and existing orders can last decades. The 2004 wooden bedroom furniture order from China is still active. The 1986 pasta order from Italy ran for over 30 years.
If you don't know whether your products are affected, find out now — before CBP finds out for you.
