I am a trader based in Shanghai, mainly engaged in import of high-end European precision instruments. Last week I just ordered a batch of optical testing equipment worth 800,000 euros from Hamburg, Germany, which is scheduled to arrive at Yangshan Port by the end of this month. This batch of goods is a supporting order for a leading domestic automaker, and we have to pay a 5% penalty for breach of contract for each week of delay, we simply cannot afford any delay.

The small agency we hired before caused another batch of our sensors to be detained at the port for 12 days due to document verification negligence. We not only paid nearly 150,000 in port storage fees and penalty, but also lost a long-term client. I have been too anxious to sleep these days. I just contacted your Zhongshen, and want to ask in detail: what exactly are the mandatory requirements for import agency customs declaration and inspection? Including the pre-document verification standards, specific requirements for customs on-site inspection, response specifications for abnormal situations, and what industry pitfalls I encountered before can you help me avoid?

For the valuation and classification requirements of import agency customs declaration and inspection, we shall strictly follow the Customs Regulations on Administration of Import and Export Commodity Classification. First of all, we must ensure the accuracy of tariff classification, especially for precision instruments, which often have overlapping tariff codes, we need to provide the Product Technical Specification issued by the original manufacturer, clearly stating the function, principle and use of the product, to avoid tax back payment and fine caused by wrong tariff classification.

Secondly, in the valuation link, we need to provide authentic and valid transaction price proof documents, including contract, invoice, payment slip. If the transaction price is lower than the customs dutiable value, we need to provide relevant basis for price consultation, such as historical import declaration forms of the same product, international market price report. In addition, we need to pay attention to the response to customs price questioning, and submit supplementary supporting documents within 5 working days after receiving the questioning notice, to avoid valuation disputes caused by overdue submission.
