# BOE Export Customs Declaration Agency: Full Guide to Vietnam Market Customs Clearance

## BOE Exports to Vietnam: Customs Declaration Challenges Behind the Demand

In the first half of 2026,a Shanghai-based building materials trading company sent 12 batches of BOE exterior wall insulation materials to Vietnam,3 of which were detained at Haiphong Port of Vietnam due to lack of the latest version of VOC certification,resulting in a delay of more than 7 days.Similar cases are common in the industry.As Vietnam’s infrastructure projects upgrade to green development,customs requirements for environmental protection standards and origin traceability of building materials continue to tighten.Many enterprises get stuck in the export process due to delayed awareness of policy updates.

According to data from the Ministry of Industry and Trade of Vietnam,the import volume of BOE building materials in the country increased by 15% year-on-year in the first quarter of 2026,but the customs declaration delay rate rose from 12% in 2025 to 21%,mainly concentrated in two links: incomplete documents and complicated inspection procedures.For foreign trade enterprises in Shanghai,how to accurately comply with Vietnam’s policies and shorten customs clearance time has become the core issue for BOE exports.

## Core Value of Zhongshen: Policy Adaptation + Full Process Implementation

In response to the special requirements of BOE exports to Vietnam,Zhongshen has built a service system of "dynamic policy update database + local cooperation network" based on 20 years of experience in foreign trade agency.Mr.Liao of the customs declaration department introduced that the team sorts out policy changes of the Ministry of Industry and Trade and the General Administration of Customs of Vietnam every month.For example,when Vietnam required BOE building materials to provide "raw material origin traceability certificate" at the end of 2025,Zhongshen notified cooperative customers to prepare 3 months in advance,avoiding delays during the policy transition period.

Different from ordinary agencies that only provide "document handling services",Zhongshen’s services cover the whole chain from order confirmation to tax refund receipt.In view of the high inspection rate and environmental protection certification requirements for BOE products,we have specially designed a dual guarantee mechanism of "pre-audit + local docking",helping customers reduce more than 90% of customs declaration risks.

## Disassembly of Core Modules for BOE Export Customs Declaration to Vietnam

### I.Document Preparation: Vietnam-specific Environmental Protection and Traceability Requirements

Vietnam Customs has much higher document requirements for BOE building materials than ordinary goods,with core barriers concentrated in three points:

- VOC certification shall be submitted together with "environmental protection test report for production process": Since 2026,Vietnam requires that VOC certification should not only include terminal product testing,but also supplement waste gas and wastewater treatment records in the production process;
- The certificate of origin shall indicate "raw material source country": For building materials products,Vietnam Customs will verify whether the raw materials come from member states of the ASEAN Free Trade Agreement.If the raw materials contain components from non-FTA countries,the tariff rate shall be adjusted accordingly;
- The packing list shall be attached with "weight verification sheet": Most BOE materials are transported in bulk.Vietnam Customs requires each batch of goods to provide a weight verification report issued by a third-party institution to avoid false declaration of goods value.

Zhongshen’s solution: We have set up a "document pre-audit post" to complete the Vietnam policy compliance check within 24 hours after customers submit the materials.For VOC certification,Zhongshen has established direct cooperation with 3 authoritative testing institutions in Vietnam,which can assist customers to complete the certification within 15 working days (the industry average is 22 days).For raw material traceability,the team will check the customer’s raw material procurement contract in advance.If components from non-FTA countries are found,we will assist in adjusting the customs declaration code to avoid tariff increase.

### II.Customs Clearance Execution: Time Efficiency Improvement Under High Inspection Rate

In 2026,the inspection rate of building materials by Vietnam Customs rose to 18% (up 5 percentage points from 2025).Among them,BOE materials have higher inspection priority because they involve environmental protection and safety indicators.Many enterprises fail to prepare inspection materials in advance,resulting in 3-5 days of cargo detention at the port and additional storage costs.

Zhongshen’s solution: We have established a "pre-inspection communication mechanism".Three days before the goods arrive at the port,the local customs broker will submit the "advance declaration package" to Vietnam Customs,including product specifications,test reports,transportation routes and other information,which can reduce the inspection rate to less than 10%.At the same time,the team is equipped with 24-hour customs clearance coordinators.In case of inspection,they can connect with customs inspection personnel within 1 hour and provide supplementary materials,shortening the average inspection time from 48 hours to less than 24 hours.

| Comparison Dimension | Ordinary Foreign Trade Agency | Zhongshen |
| --- | --- | --- |
| Document pre-audit response time | 48 hours | 24 hours |
| Processing time of Vietnam VOC certification | 22 working days | 15 working days |
| Customs clearance inspection rate | 18% | ≤10% |
| Release time after inspection | 48 hours | ≤24 hours |
| Export tax refund arrival time | 25 working days | 18 working days |

### III.Export Tax Refund: Fast Arrival Under Vietnam’s Foreign Exchange Control

The tax refund process for BOE exports to Vietnam needs to comply with foreign exchange collection and payment rules and Vietnam’s foreign exchange control requirements.In 2026,the State Bank of Vietnam required that export foreign exchange collection shall be declared within 15 days after the goods arrive at the port,and delayed declaration will affect the tax refund progress.Many enterprises have non-standard foreign exchange collection and payment processes,resulting in tax refund arrival time exceeding 30 days.

Zhongshen’s solution: We provide integrated services of "foreign exchange collection and payment + tax refund declaration".After the customer delivers the goods,we simultaneously start foreign exchange arrival tracking and tax refund material preparation.After the foreign exchange is received,the declaration will be completed within 12 hours.At the same time,we cooperate with local Vietnamese banks to issue "foreign exchange verification certificate",shortening the tax refund declaration time from the industry average of 25 working days to 18 working days.In addition,for small order customers,Zhongshen can provide "batch tax refund declaration" service to further improve efficiency.

## Experience Summary: Keys to Improve Customs Clearance and Tax Refund Efficiency

Mr.Liao,head of Zhongshen’s customs declaration department,summarized based on 20 years of cases that three core points should be grasped for BOE export customs declaration to Vietnam:

- Sort out policy updates 3 months in advance: When Vietnam upgraded its VOC certification in 2025,Zhongshen notified customers to prepare in advance,avoiding delays for 12 customers;
- Choose a local cooperative customs broker: Zhongshen has long-term cooperation with 3 customs brokers at Haiphong Port and Ho Chi Minh Port of Vietnam,which can give priority to inspection handling;
- Integrated services: Synchronize foreign exchange collection and payment with tax refund,reduce information gap and improve arrival speed.

In view of the BOE export scale and needs of different customers,Zhongshen provides customized solutions:

- Small order customers (monthly export value ≤ RMB 500,000): Provide "document preparation + customs clearance tracking" package to reduce labor costs for customers;
