Guide to Export Customs Procedures for Enterprises

Export customs procedures are a pivotal operational link that determines delivery schedules and financial safety in international trade. A thorough understanding of clearance regulations enables businesses to optimize logistics costs, prevent administrative penalties, and ensure smooth cargo flow into the global market.

The article below systematically details the necessary regulations, required documentation sets, and a 5-step process for accurate export customs procedures tailored for B2B enterprises.

1. Prerequisites To Prepare Before Export Customs Procedures

To ensure smooth customs declarations, manufacturing and trading enterprises must fulfill foundational conditions prior to submitting the declaration:

• Register Enterprise Code with Customs Authorities:

  • Enterprises use their corporate tax code to register on the National Single Window portal system.

  • Ensure the digital signature (Token) is valid and integrated into the electronic customs declaration software (VNACCS/VCIS).

• Check Export Commodity Policies:

  • Determine whether the goods fall under free export, conditional export (requiring specialized licenses), or prohibited export lists.

  • Accurately identify the product's HS Code to check export tax rates and related legal obligations.

• Build Sales Channels and Confirm International Orders:

  • Prepare complete buyer information via commercial contracts (Sales Contracts) or official Purchase Orders (PO).

  • Acquiring buyers through B2B platforms like Alibaba helps enterprises access reputable corporate buyers directly, thereby standardizing commercial information right from the order stage.

  • New exporters should proceed with Alibaba account registration to digitize product catalogs and receive guidance from the Alibaba Vietnam ecosystem.

  • To ensure smooth initial operations, enterprises can utilize storefront setup consulting services from professional partners to standardize capacity profiles.

  • Proactively establishing an official storefront offers a major advantage in creating transparent export documentation sets that meet international buyers' strict standards.

2. Complete Standard Export Customs Documentation Set

A complete export customs documentation set includes original and electronic documents as specifically regulated below:

• Export Customs Declaration:

  • Successfully transmitted electronically via the VNACCS/VCIS system and received a declaration number confirmation.

• Commercial Invoice:

  • 01 copy clearly showing total shipment value, Incoterms delivery conditions (FOB, CIF, EXW...), payment methods, and information of both parties.

• Packing List:

  • 01 copy detailing package quantity, gross weight (GW), net weight (NW), and volume (CBM).

• Sales Contract:

  • Legal document serving as a basis for verifying customs valuation and delivery terms between buyer and seller.

• Export Permit or Specialized Inspection Results (if applicable):

4. Top 4 Focus Points To Help Enterprises Avoid Errors In Customs Declarations

To ensure smooth clearance and prevent extra costs, enterprises should pay special attention to:

1. Document Information Consistency:

   • Goods description, quantity, weight, HS Code, and invoice value on Commercial Invoice, Packing List, and Customs Declaration must be completely identical.

2. Verify Loading and Unloading Ports Accurately:

   • Correctly declare Port of Loading and Port of Discharge according to international customs code standards to avoid declaration rejection.

3. Manage Declaration Transmission Time and Container Drop-off:

   • Transmit the customs declaration 1–2 days before dropping off containers at the port yard to allow sufficient time for handling Yellow or Red Channels, avoiding missed vessel closing times.

4. Prepare Customs Valuation Explanation Documents:

   • For items with questioned declared values, enterprises should prepare contracts, bank payment proofs, and cost calculation sheets in advance for explanation upon customs request.

5. Summary

Mastering export customs procedures for enterprises is a foundational step that enables manufacturers to proactively manage supply chain timelines. Meticulous document preparation, adherence to declaration processes, and leveraging modern B2B trade platforms empower enterprises to enhance competitiveness and confidently expand Vietnamese goods across the international market.
