Anti-Dumping Duty Calculator — ADD & CVD Cost Analysis

Calculate anti-dumping duty (ADD) and countervailing duty (CVD) cost on imports. With US ADD/CVD rates ranging from 10% to 300%+, understanding your duty exposure is critical for sourcing decisions.

Quick answer: ADD/CVD rates can exceed 200% of product value for some Chinese imports. On $500K annual imports with 120% ADD: $600K in additional duty — often more than the product cost itself.

How to Use This Calculator

  1. Look up ADD/CVD rates on USITC.gov — search by HTS code and country — rates change as annual reviews are conducted.
  2. Include all duty layers — MFN + ADD + CVD + Section 301 — they all stack. Some Chinese goods face 150%+ combined rates.
  3. Compare alternative sourcing — enter alternative country duty rate to calculate annual saving from supply chain diversification.

Worked Example

$500K imports, 5% normal duty, 120% ADD, 25% CVD, 25% Section 301, alternative at 8%.

  1. Total rate: 175%
  2. Annual duty: $875,000
  3. Total landed cost: $1,375,000
  4. Alternative (8%) duty: $40,000
  5. Saving by reshoring: $835,000/yr

At 175% combined duty, the alternative source is almost always worth it even at higher FOB prices — the duty saving alone of $835K/year outweighs most unit cost differences.

Frequently Asked Questions

USITC (usitc.gov) has the HTS database. CBP ACE portal shows current orders. Federal Register publishes annual ADD/CVD reviews. Commerce Department (commerce.gov) lists active orders. Note: ADD/CVD rates are product- and company-specific — the rate for your supplier may differ from the country-wide average rate.

First-sale valuation (using factory price vs agent price) can reduce the duty base. Scope rulings can establish that your product isn't covered by the order. Customs classification changes (engineering the product) sometimes move it to a different HTS code not subject to ADD/CVD. All these approaches require CBP and legal guidance — get specialist advice before implementing.
