Antidumping Margin Calculation Programs

On this page you will find the generic antidumping (AD) margin calculation programs. These programs are the starting point of our AD calculations. For a particular company in a proceeding, a case analyst will modify the boilerplate code as required for their case.

There are two types of AD calculations market-economy (ME) and nonmarket-economy (NME). The AD programs (including a common macro program) required for each are found below. In both types, we compare prices in the United States to some minimum standard called, Normal Value (NV).

Common Macros Program

The required Common Macros program was established to accommodate common methodological code and generic utility functions and that both ME and NME programs utilize in their execution.

  1. Common Macros [28KB]

Market-Economy Programs

In ME calculations, we base NV on the company s actual costs and prices in the comparison market. If no suitable comparison market is found, we base NV on Constructed Value (CV) which is a cost-based buildup of a surrogate price.

Here are the three programs used in ME calculations (along with the Common Macros Program):

  1. ME Comparison Market [109KB]

 2. ME Margin Calculation [118KB]

 (06/27/2025)

 3. ME Macros [296KB]

 (06/27/2025)

When a comparison market is the basis of NV, the first program used is the ME Comparison Market (CM) program. The CM program is where the case analyst enters information about the company s costs and sales in the comparison market. The ME Macros program is where the bulk of the code is stored. When the CM program is executed, it calls up the relevant portions of code from the ME Macros program to process the CM sales. After the CM Program is run, the ME Margin Calculation program is completed by the analyst. When executed, the ME Margin Calculation program calls in relevant portions of the ME Macros Program to process U.S. sales and then compare them to CM sales or CV to calculate the AD duty rate. When there is no comparison market, only the ME Margin Calculation program and ME Macros program are required for homes of U.S. prices straight to CV.

Nonmarket-Economy Program

In nonmarket-economy AD calculations, NV is comprised of the company s factors of production (i.e., recipe for manufacturing the goods in question) valued in some appropriate surrogate country.

Here is the NME program used in NME calculations (along with the Common Macros Program):

 1. NME Margin Calculation SAS [152KB]

In all NME calculations, the analyst fills in the required case-specific information.

Global Business Navigator Chatbot Beta

Welcome to the Global Business Navigator, an artificial intelligence (AI) Chatbot from the International Trade Administration (ITA). This tool, currently in beta version testing, is designed to provide general information on the exporting process and the resources available to assist new and experienced U.S. exporters. The Chatbot, developed using Microsoft’s Azure AI services, is trained on ITA’s export-related content and aims to quickly get users the information they need. The Chatbot is intended to make the benefits of exporting more accessible by understanding non-expert language, idiomatic expressions, and foreign languages.

Limitations

As a beta product, the Chatbot is currently being tested and its responses may occasionally produce inaccurate or incomplete information. The Chatbot is trained to decline out of scope or inappropriate requests. The Chatbot’s knowledge is limited to the public information on the Export Solutions web pages of Trade.gov, which covers a wide range of topics on exporting. While it cannot provide responses specific to a company’s product or a specific foreign market, its reference pages will guide you to other relevant government resources and market research. Always double-check the Chatbot’s responses using the provided references or by visiting the Export Solutions web pages on Trade.gov. Do not use its responses as legal or professional advice. Inaccurate advice from the Chatbot would not be a defense to violating any export rules or regulations.

Privacy

The Chatbot does not collect information about users and does not use the contents of users’ chat history to learn new information. All feedback is anonymous. Please do not enter personally identifiable information (PII), sensitive, or proprietary information into the Chatbot. Your conversations will not be connected to other interactions or accounts with ITA. Conversations with the Chatbot may be reviewed to help ITA improve the tool and address harmful, illegal, or otherwise inappropriate questions.

Translation

The Chatbot supports a wide range of languages. Because the Chatbot is trained in English and responses are translated, you should verify the translation. For example, the Chatbot may have difficulty with acronyms, abbreviations, and nuances in a language other than English.
