Instructions for customs declaration of high-pressure hydrogen compressors (reciprocating)
Thread Content
The high-pressure hydrogen compressors imported by our company operate at a pressure of around 320 kilograms, with a flow rate of 500 kg/h. We need to apply to the customs for tax exemption, but since these compressors fall under the category of \"reciprocating compressor units (with shaft power ≤ 7000 KW)\" listed in the customs’ \"Catalogue of Import Equipment Not Eligible for Tax Exemption,\" they do not meet the conditions for exemption. After communicating with the customs, we were informed that if our company can provide conclusive technical documentation proving that such equipment cannot be produced domestically, we may submit an application to the customs requesting their assistance in forwarding it to the relevant authorities for consideration (simultaneously, our company will also need to coordinate with the chemical industry association to obtain the necessary certification documents). Could the experts help find similar proofs, or papers from relevant journals published on this topic as well? Emergency! Thank you
I did the same thing when I handled customs clearance before, but you can explain the purpose and function of this compressor in your device, as well as the quality of the materials used domestically – it cannot be replaced. For example, one of the items in the technical specifications for customs declaration is \"Functions and Uses.\" I used to write it in this way: This compressor is used in the XX hydrogenation XX unit; it is known as the XX compressor. It is a key component of the entire XX hydrogenation XX unit. By compressing low-pressure hydrogen gas, it continuously supplies hydrogen to the reaction system of the XX hydrogenation XX unit, thereby meeting the hydrogen requirements for hydrogenation processes within that unit and maintaining the pressure needed in its reaction system. Without the XX compressor continuously supplying fresh hydrogen, the XX hydrogenation unit cannot carry out the hydrogenation reaction, and production in the entire facility will come to a halt.
