General administration of quality supervision, inspection and quarantine recently, according to data released in 2014, the national export enterprises under the influence of foreign technical trade measures ratio is 36.1%.Ningbo eighth foreign technical trade measures to influence the results of the survey also shows that in 2014, with technical regulations, standards and conformity assessment procedures as the core of foreign technical trade measures to ningbo export direct loss of $1.662 billion, causing additional cost of $918 million.Ningbo export trade barriers into the largest "stumbling block", including the mechanical and electrical equipment, textile, mining, light industry, toys, metal rubber plastic, paper, wood advantage of agricultural products and food industry, not of metal.From the effects of technical trade measures to specific categories, various industries roughly similar.Among them, the most frequent technical trade measures from "certification program requirements," followed by "toxic and harmful substances limits", "general technical standard" and "environmental protection and energy sing requirements.Undoued, foreign technical barriers to trade to upgrade to the direct economic losses from the part of the enterprise's export, but the standard group (Hong Kong) co., LTD. Think, whether the upgrading of technical barriers to trade can increase the industry testing instruments such as textile testing instrument at home and abroad market?On the one hand, the foreign technical barriers to trade to upgrade, the industry will need to deal with this kind of upgrading to the development of an enterprise to strengthen the quality control and testing.Although the raw materials and labor costs rise, will squeeze the enterprise profit space, will bring difficulty to the enterprise's normal production.But, as long as the enterprise to strengthen product development efforts, and constantly introduce testing instruments products in line with market demand, enterprises can win in the industry reshuffle.This is an opportunity for instrumentation industry.Foreign technical barriers to trade, on the other hand, the upgrade is that emerging markets following the developed countries, the standard and certification with the attention.Such an underdog, continuous fermentation, even will cause the huge market of textile testing instrument.Whether can directly drive the textile testing instrument overseas, become another opportunity?仪器、仪表
