General regulations on how to do import-export customs procedures

Basic legal principles

The customs declaration process must strictly comply with current laws. Businesses must update regulations regularly to avoid errors. Using a digital signature is currently a mandatory requirement. The VNACCS data system receives information continuously 24/7. This creates maximum favorable conditions for all exporters. Good compliance helps enhance trade credibility.

Entities required to declare

Every organization or individual with trading goods must declare. The goods owner or an authorized agent performs this directly. Transport vehicle operators also belong to this group of subjects. According to marine logistics market report, the volume of filings is growing continuously. Identifying the correct subject helps the customs clearance process take place more smoothly.

Standard document filing deadlines

Businesses need to accurately remember the deadline for submitting declarations. For export goods, submit after gathering goods at the yard. No later than four hours before the vehicle exits. For import goods, submit before the goods arrive at the border gate. Or submit within thirty days from when the goods arrive at the port.

Regulations for filing documents include the following important principles:

• Electronic customs declarations are valid for circulation within fifteen days from the date of official registration on the system.
• Attached documents must be fully signed with a valid digital signature by the legal representative of the import-export business.
• Green channel goods are automatically approved for customs clearance by the system immediately without the need for paper document inspection or physical inspection.
• Yellow channel goods require customs officers to conduct a detailed inspection of all paper documents before granting customs clearance.
• Red channel goods must undergo a physical inspection process at the container yard under the strict supervision of officers.

As a practical example, Minh Ca Mau Seafood Company once faced difficulties. They did not clearly understand the deadline for submitting electronic declarations. Thanks to timely adjustments, they reduced two days of yard storage. The cost savings amounted to ten million VND per shipment. Another case is Tien Giang Fruit Enterprise exporting to China. They submitted their documents exactly four hours before the ship departed. As a result, the shipment of dragon fruit was cleared smoothly. The company avoided a late penalty of twenty million VND.

Guide to preparing customs documentation for import and export goods

List of mandatory documents

The preparation of import customs documentation requires accuracy. Core documents include commercial contracts and commercial invoices. Packing lists are also indispensable documents. In addition, bills of lading are important proof of delivery. Certificates of origin help businesses enjoy tariff preferences.

Specialized documents for agricultural and aquatic products

Agricultural and aquatic goods require many complex specialized licenses. Quarantine certificates for animals and plants are an absolute mandatory requirement. Food safety and hygiene certificates protect consumers. HNT LOGISTICS recommends that businesses prepare these documents early. This helps prevent goods from being held at the port of departure.

Common documentation errors

Many businesses often make errors of information discrepancy on invoices. The weight on the packing list does not match the actual goods. Incorrect HS codes lead to incorrect tax calculation. Signatures and seals on paper documents are blurred or missing. Thorough review helps minimize the red channel.

The standard list of documents includes the following detailed items:

• A commercial invoice that clearly and accurately shows the actual value of the entire shipment being prepared for export abroad.
• A detailed packing list stating the number of packages, net weight, and gross weight of the shipment for reconciliation purposes.
• An original bill of lading or a copy with a valid seal from the shipping line or freight forwarding agent.
• Certificate of origin Form E or Form D depending on the requirements of the importing market to enjoy special incentives.
• Specialized import licenses for categories of goods subject to special control by relevant ministries and departments.

For example, Binh Duong Agricultural Products Company exports cashews to Europe. Initially, they lacked a fumigation certificate for the wooden container. Thanks to urgent supplementation, the shipment departed on schedule as committed. They saved five million VND in storage penalty costs. Similarly, An Giang Rice Exporter prepared a very perfect set of documents. The partner's documents were processed quickly. The shipment was cleared within just four hours. International partners highly appreciate this professionalism.

Import and export customs clearance procedure

Electronic data declaration

Work import customs clearance procedure starts with an online declaration. Enterprises install ECUS software and log in using a digital signature. The declarant enters shipment information into the criteria on the software. The data is then transmitted directly to the management agency's system.

This document allows the cargo owner to take the container out of the seaport. Storage fees often arise if the delivery order is obtained late. This process requires smooth coordination between parties.

Complete tax and fee payment

Enterprises need to fulfill financial obligations before receiving goods. Types of taxes include import tax, special consumption tax, and VAT. Electronic tax payment via commercial banks is the optimal method. Tax money is updated immediately on the interconnected system. Afterward, customs officers will officially stamp customs clearance.

The 6 basic steps in the clearance procedure include:

1. Enterprises proceed to register an account and set up a valid digital signature on the unified national VNACCS portal system.
2. The person in charge proceeds to carefully check and reconcile all commercial documents related to the import shipment.
3. Proceed to transmit electronic declaration data to the customs network system and wait to receive the automatically returned channeling results.
4. Enterprises urgently pay the full amount of taxes and fees incurred in accordance with the official notification of state management agencies.
5. Promptly present the physical document set or open the yard for actual inspection of goods if the declaration is unfortunately channeled into yellow or red.
6. Perform the operation of printing the barcode to pass through the seaport customs supervision area and dispatch trucks to bring goods to the warehouse safely.

District 7 Equipment Import Company is a successful example. They transmitted the electronic declaration at two o'clock on a weekend morning. The system automatically assigned green channel and cleared customs in three seconds. This helped save one day of waiting at Cat Lai port. Meanwhile, Dong Nai Wood Enterprise imports raw materials from the US. They apply automatic electronic tax payment via partner banks. The declaration process is extremely smooth and favorable. Goods are brought to the production workshop according to the planned schedule.

The procedure stage needs to be prioritized for handling before the ship arrives at the port. Goods should be moved directly from the port to cold storage warehouses.

• Documentation staff need to declare early on the electronic software immediately upon receiving notification that goods have safely reached the destination port.
