In 2026,China-Cambodia RCEP economic and trade cooperation continues to deepen,and the demand for Cambodian agricultural products,textiles,furniture and other commodities in the domestic market grows steadily.Many Shanghai-based enterprises choose to import goods from Cambodia,but the customs clearance link involves many details such as customs policies,tariff calculation and data review.A little carelessness may lead to cargo delays and additional costs.Combining with practical operation experience,this article systematically sorts out the core process of Cambodia import customs clearance agency,and explains how professional agents help enterprises avoid risks.

I.Preparatory Stage – Accurate Policy Alignment,Avoid Document Omissions

Role of Zhongshen:

Manager Meng is responsible for preliminary document review,and will accurately check the HS code according to the material,use and other details of the commodity.For example,Mr.Wang’s enterprise imported Cambodian dried mango,Manager Meng helped confirm its HS code is 08134000,which meets the RCEP preferential tariff requirements.At the same time,he assists in processing RCEP certificate of origin,aligns with Cambodian exporters on the filling specification of the certificate in advance,and avoids invalid use due to format errors.For commodities requiring import license,Manager Meng will remind the enterprise to prepare materials 10 working days in advance and coordinate with relevant Cambodian departments for processing.For example,for an enterprise importing Cambodian medicinal plants,Manager Meng’s team assisted in processing the animal and plant quarantine permit in advance,ensuring that the goods can be declared directly after arrival at the port.

II.Cargo Arrival Declaration Stage – Submit Documents Efficiently,Shorten Customs Clearance Cycle

Stage Objective: Complete electronic declaration within 24 hours after cargo arrival,calculate tariff and value-added tax accurately,avoid container detention fee caused by delayed declaration.

Supervisor You is responsible for coordinating with Cambodian Customs declaration system,completes pre-declaration test before the 10th of each month to ensure smooth declaration during peak hours.At the same time,a tariff calculation database has been established,which can calculate accurately according to the latest 2026 tariff policy.For example,for an enterprise importing Cambodian textiles,Supervisor You confirmed that the tariff rate is 0,avoiding extra tariff payment.In addition,Supervisor You’s team will check the commodity value with the enterprise before declaration to ensure consistency with the invoice and avoid customs doubt caused by value discrepancy.

Ms.Qi’s team is responsible for on-site inspection coordination,and checks the consistency between the packing list and the actual goods before the cargo arrives at the port.For example,for Mr.Meng’s enterprise importing Cambodian furniture,Ms.Qi checked the size and quantity of each piece of furniture in advance to avoid non-compliance in inspection.For commodities requiring foreign language marking,Ms.Qi will assist the enterprise with translation and marking in advance,for example,marking the shelf life in Khmer for food commodities to ensure compliance with requirements.If Customs raises any doubt,Ms.Qi will provide supplementary documents in time,such as the textile composition certificate for an enterprise,quickly resolve the doubt and shorten the inspection time from the conventional 2 days to 1 day.

IV.Follow-up Settlement and Archiving Stage – Transparent Cost Settlement,Long-term Document Retention for Future Reference

• Lossofdocumentsaffectssubsequentcustomsfilingortaxrefundapplicationforfutureimports

Role of Zhongshen:

Supervisor Ran is responsible for cost settlement and document archiving,and attaches the charging basis of each fee (such as tariff payment receipt,port charging voucher) to the list.For example,the agency fee for an enterprise’s imported goods is charged at 1% of the cargo value,and the cargo value and calculation method will be marked in the list.At the same time,an electronic file system has been established,all documents are scanned and stored,and can be retrieved at any time.For example,when Mr.You’s enterprise needed to handle subsequent tax refund,Supervisor Ran helped quickly retrieve documents such as tariff payment receipt,saving the enterprise’s time.

Although Cambodia’s import customs clearance process has been simplified in 2026,the involved policy details and operation specifications still require professional experience support.Zhongshen has been deeply engaged in the foreign trade agency industry for more than 20 years,is familiar with the latest policy changes of Cambodian Customs,and has dedicated staff responsible for each link.From preliminary document review to subsequent document archiving,Zhongshen avoids risks throughout the whole process,helping enterprises shorten the customs clearance cycle by more than 30% and save additional costs by about 20%.For example,last year a Shanghai enterprise imported Cambodian agricultural products,it only took 5 days to complete customs clearance through Zhongshen’s agency,which saved 3 days compared with self-processing,and avoided extra tariff caused by incorrect certificate of origin.
