Common Questions About Customs Declaration and Inspection
What basic documents are required for customs declaration?
Basic documents include: packing list, commercial invoice, sales contract, declaration elements (product name, HS code, brand, material, purpose, etc.). If it is a legally inspected cargo, a customs clearance form is also required.
What is the validity period for import and export customs declaration?
Customs usually completes the review of electronic data for export customs declaration within 24 hours after declaration; import declaration should be completed within 14 days from the date of arrival declaration of the means of transport. Late declaration fees will be incurred if overdue.
What if the HS code classification is incorrect?
Kang Sheng Yun Tong has a professional classification team. If the customs have objections to the classification after declaration, we will assist you in negotiating with the customs as soon as possible, provide supporting materials such as product manuals, and strive for the most favorable classification results.
Can export customs declaration apply for tax refund?
Yes. As long as the goods are formally declared for export, the company has import and export operating rights, and has obtained a special VAT invoice issued by the supplier, an export tax refund can be applied for from the tax bureau. Kang Sheng Yun Tong can provide you with compliant customs declaration documents and settlement support to help your company successfully complete the tax refund application.
How long does customs inspection usually take?
Normal inspection is usually completed within 1 working day. If the goods require testing and analysis, the time will be extended. We provide inspection follow-up services to ensure process transparency.
If goods are inspected by customs, who bears the incurred costs?
Customs inspection itself does not incur fees, but associated costs such as hoisting, relocation, and warehousing generated during the inspection process are typically borne by the cargo owner. Kang Sheng Yun Tong will inform clients of relevant policies in advance and assist with coordination at the inspection site to minimize additional expenses.
