An export in international trade is a good or service produced in one country that is sold into another country. The seller of such goods and services is an exporter; the foreign buyer is an importer. Export and import Export of goods often requires the involvement of customers authorities. From the buyer's point of view an export is an import. Firms Many manufacturing firms begin their global expansion as exporters and only later switch to another mode for serving a foreign market. Process Methods of exporting a product, goods or information include mail, hand delivery, air shipping, shipping by vessel, uploading to the Internet, or downloading from a website. Barriers Export barriers are divided into four large categories: motivational, informational, operational/resource-based, and knowledge. Trade barriers are government laws, regulations, policy, or practices that protect domestically made products from foreign competition. While restrictive business practices sometimes have a similar effect, they are not usually regarded as trade barriers. The most common foreign trade barriers are government-imposed measures and policies that restrict, prevent, or impede the international exchange of goods and services. Tariffs A tariff is a tax placed on a specific good or set of goods exported from or imported to a countryside, creating an economic barrier to trade. A tariff may be used when domestic producers are having difficulty competing with imports. Tariffs may also be used to protect an industry that the country views as a matter of its national security. Some industries receive protection that has a similar effect to subsidies; tariffs reduce the industry's incentives to produce goods quicker, cheaper, and more efficiently, becoming ever less competitive. The third basis for a tariff involves dumping. When a producer exports at a loss, its competitors may term this dumping. Another case is when the exporter prices a good lower in the export market than in its domestic market. The purpose and expected outcome of a tariff is to encourage spending on domestic goods and services rather than their imported equivalents. Tariffs can create tension between countries. Examples include the United States steel tariff of 2002, and when China placed a 14% tariff on imported auto parts. Such tariffs usually lead to a complaint with the World Trade Organization (WTO) which sets rules and attempts to resolve trade conflicts. If that is unsatisfactory, the exporting country may choose to put a tariff of its own on imports from the other nation.

Exporting may help a company achieve experience curve effects and location economies in their home country. Ownership advantages include the firm's assets, international experience, and the ability to develop either low-cost or differentiated products. The locational advantages of a particular market are a combination of costs, market potential and investment risk. Internationalization advantages are the benefits of retaining a core competence within the company and threading it though the value chain rather than to license, outsource, or sell it. In relation to the eclectic paradigm, companies with meager ownership advantages do not enter foreign markets. If the company and its products are equipped with ownership advantage and internalization advantage, they enter through low-risk modes such as exporting. Exporting requires significantly less investment than other modes, such as direct investment. Export's lower risk typically reduces the rate of return on sales versus other modes. Exporting allows managers to exercise production control, but does not provide them the option to exercise as much marketing control. An exporter enlists various intermediaries to manage marketing management and marketing activities. Exports also has effect on the Economy. Businesses export goods and services where they have a competitive advantage. This means they are better than any other country at providing that product or have a natural ability to produce either due to their climate or geographical location etc. Disadvantages Exporting may not be viable unless appropriate locations can be found abroad. High transport costs can make exporting uneconomical, particularly for bulk products. Another drawback is that trade barriers can make exporting uneconomical and risky. For small and medium-sized enterprises (SMEs) with fewer than 250 employees, export is generally more difficult than serving the domestic market. The lack of knowledge of trade regulations, cultural differences, different languages and foreign-exchange situations, as well as the strain of resources and staff, complicate the process. Two-thirds of SME exporters pursue only one foreign market. Exports could also devalue a local currency to lower export prices. It could also lead to imposition of tariffs on imported goods.
