According to reports, the adjustments related to the chemical industry mainly include the following points: First, considering the concerns of the international community on environmental protection issues, the structure of some product catalogues related to environmental protection issues has been adjusted. According to the EU, Australia and the Rotterdam Convention, the Montreal Protocol on Substances that Deplete the Ozone Layer, etc., the names and nomenclature of asbestos, mineral ash, mercury-containing compounds, pesticides, and other related chemicals have been adjusted or modify. As the additional captafol, methamidophos, chlordimeform, fluoro-acetamide, and phosphamidon monocrotophos, parathion and parathion-methyl, pentachlorophenol and dinoseb, dieldrin, Le Killing crickets, ethyl esters, sterols and other sub-items, further unified and standardized names, in order to facilitate the monitoring of international trade in hazardous chemicals. Second, in order to meet the needs of international anti-dumping verification, the tax numbers of chemical products that were originally relatively general were subdivided. For example, the two tariff numbers under the “other polyester†tariff lines were subdivided into “polybutylene terephthalateâ€. "Ester", "unsaturated polyester", "other polyester" 3 tariff numbers. Third, due to technological development and changes, some high-tech products or new products need to be listed separately or the relevant codes must be reorganized. Such as the addition of yttrium oxide, yttrium oxide and other new product tax numbers. Fourth, in the changes in tax rates that were accompanied by the adjustment of the “Tax Regulations†announced by the General Administration of Customs at the same time, most of the tax rates on chemical products exported have increased, reflecting the state's restrictions on “two high and one capital†products. According to the tariff reduction obligations promised by China's accession to the WTO, imported products are almost all reflected in the reduction of the tax rate. For instance, the quota tax rates for three kinds of chemical fertilizers including urea, compound fertilizer and diammonium hydrogen phosphate were reduced from 4% in 2006 to 1%, which reduced the MFN tariff rate for 44 tax purposes such as polyethylene in the “Import Tariffâ€.
It is also understood that in order to be more rigorous and more uniform in terms of semantics, the new "Tax Code" has amended the provisions of the relevant sections, items or subheads without changing the scope of the original items.
Pressure vessel and boiler quality steel are commonly found throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry. The companies in these industries set the highest demands in terms of quality, testing and conditions of supply, and we have all the necessary expertise to meet these demands.
There is a huge range of different chemicals and liquid that that stored and processed under pressure. These range from relatively benign substances such as milk and palm oil to crude oil and natural gas and their distillates to highly lethal acids and chemicals such as methyl isocyanate. So of these processes need the gas or liquid to be very hot, whilst others contain it at very low temperatures. As a result there is a wide variety of different pressure vessel steel grades that meet the different use cases.
