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 fill in the company’s case-specific
information in the required sections and make any changes to the boilerplate code
required for the situation.
There are two types of AD calculations: 1) market-economy (ME); and 2) nonmarket-economy
(NME). The separate sets of AD programs required for each are found below. In both
types, we compare prices in the United States to some minimum standard called, Normal
In ME calculations, we base NV on the company’s actual costs and prices in the comparison
market. The comparison market can be either the home country of the respondent or some
other suitable 3rd country. If no suitable comparison market is found, we base NV on
Constructed Value (CV) which is a cost-based build up of a surrogate price.
Here are the three programs used in ME calculations with differential pricing (with Cohen's d Test):
When a comparison market is the basis of NV, the first program used is the CM Program.
The CM Program is where the case analyst enters information about the company’s costs
and sales in the comparison market. The 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 Macros Program to process the CM sales and saves the results for use in the
Margin Program. After the CM Program is run, the Margin Program is completed by the
analyst. When executed, the Margin program calls in relevant portions of the 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 Margin Program and
Macros Program are required for comparisons of U.S. prices straight to CV.
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 with differential pricing (with Cohen's d Test):
In all NME calculations, the Margin Program is required. In the Margin Program, the
analyst fills in the required case-specific information. When there is an allegation
of Targeted Dumping, the Targeted Dumping Macros program is also required. The code
stored in the Targeted Dumping Macros program is automatically called up by the
Margin Program when needed.
