Nontariff barriers (NTBs) represent administrative regulations, policies, and
procedures, i.e., quantitative and qualitative barriers that directly or indirectly
impede international trade.
1. Subsidies. Subsidies consist of direct or indirect financial assistance from
governments to their domestic firms to help them overcome market
imperfections and thus make them more competitive in the marketplace.
Recently we have seen government intervention shoring up floundering
companies and industries. One of the most popular forms of government
subsidy can be seen in the agriculture industry. From the standpoint of
market efficiency, subsidies are more justifiable than tariffs because they
seek to overcome, rather than create, market imperfections. However, many
international frictions result from disagreements about the definition of a
subsidy.
2. Aid and Loans. Governments may give aid and loans to other countries but
require that the recipient spend the funds in the donor country; this is known
as tied aid or tied loans. In this way some donor products that might
otherwise be noncompetitive may find limited international markets.
However, there is growing skepticism about the value of tied aid because it
can slow down the development of local suppliers in developing countries
and shield suppliers in the donor countries from competition.
3. Customs Valuation. Because of the temptation to declare a low invoice
price in order to pay a lower ad valorem tariff, it is sometimes difficult to
determine the true value of traded products. Due to the many different
products traded and the differences being minute in some cases, it is easy to
misclassify a product and receive a lower tariff. First, customs officials
should use the declared invoice price. If there is none, or if the authenticity
of the value is in doubt, then customs agents may assess the shipment on the
basis of the value of identical (preferable) or similar (acceptable) goods
arriving at about the same time. Further, because countries often impose
different import barriers on products sourced from different countries,
customs officials must also determine a product’s true origin.
4. Other Direct Price Influences. Other means that countries may use to
affect prices include establishing special fees for consular and customs
clearance and documentation, requirements that customs deposits be made
in advance of shipment, and minimum price levels at which products can be
sold after they receive customs clearance.
C. Nontariff Barriers: Quantity Controls
Governments use a variety of nontariff barriers to directly affect the quantity of
imports and exports. When the quantity of imports is limited, the resulting shift
in the supply curve means that the equilibrium price will then be higher.
1. Quotas. A quota represents a numerical limit on the quantity of a product
that may be imported or exported in a given period of time. (Because of the
increase in the equilibrium price, quotas may increase per-unit revenues for
firms that participate in the market.) Voluntary export restraints (VERs)
are negotiated limitations of exports from one country to another and, as in
