# Customs Clearance Process and Tax Refund Practical Operations for Machinery Export to Vietnam

## Opportunities and Compliance Challenges of Machinery Export to Vietnam Market

In 2026,Vietnam’s manufacturing automation transformation has entered a deep-water zone,with explosive growth in demand for CNC machine tools,textile machinery and plastic processing equipment.However,complex trade barriers often hide behind opportunities.Vietnam Customs has strengthened its supervision over imported machinery unprecedentedly,with extremely detailed regulations especially on HS code classification,age restrictions for old mechanical and electrical products,and energy efficiency standards.Many domestic enterprises,when trying to export for the first time,often face the risk of goods being detained at ports or returned due to unfamiliarity with local policies.

Zhongshen has been deeply engaged in the foreign trade agency field for more than 20 years,and is well aware of the pain points of machinery export.Manager Xu pointed out that machinery usually has the characteristics of high value,complex technical parameters,and high frequency of commodity inspection.It is difficult to solve compliance issues solely relying on freight forwarders.Professional export agency services are not just about running errands to submit documents,but more about helping enterprises avoid potential tax and customs risks before goods depart through pre-classification and compliance consulting,ensuring that every transaction can be completed safely and efficiently.

## Precise Document Preparation: The First Line of Defense Against Return Risks

In the machinery export process,documents are the core.Vietnam Customs has extremely strict checks on "document-goods consistency",and any parameter deviation may lead to a surge in customs inspection rate.For machinery,invoices,packing lists and contracts must clearly list the brand,model,production year,voltage and power,and serial number.

Manager Xu emphasized that many enterprises easily overlook the importance of technical manuals.In the latest regulatory environment of 2026,Vietnam Customs requires a technical parameter list in both Chinese and English,which must be completely consistent with the nameplate information.After taking over the agency business,Zhongshen will first conduct a strict pre-review of all documents provided by the enterprise.For old machinery and equipment,the agency team will specially check whether the factory date is within the allowable import period,and assist the enterprise in handling the necessary "Pre-Shipment Inspection Certificate for Old Mechanical and Electrical Products".Although this link is cumbersome,it is a key barrier to prevent goods from being returned due to "prohibited import" after arriving at the port.

### Core Document Review Checklist

- The trade contract must clearly indicate the trade terms (FOB/CIF) and payment method to avoid foreign exchange verification problems caused by vague clauses.
- The commercial invoice must clearly list the suggested HS code of the machine,so that Vietnam Customs can quickly identify the tax rate.
- The packing list must include gross and net weights and packaging dimensions.Especially for overweight,oversized bulk equipment,accurate volume data must be provided to arrange shipping space.
- For used equipment,a certificate of origin,equipment condition statement and renovation records (if any) must be provided.

## Customs Clearance and Logistics: Breaking Through Unique Technical Barriers of Vietnam Customs Clearance

When exporting machinery to Vietnam,the customs clearance link is often the most time-consuming.Vietnam Customs implements strict valuation management for high-value mechanical and electrical products.If the declared price is lower than the minimum price limit of the customs risk system,the goods will be automatically transferred to the valuation and verification channel,leading to long-term detention fees.In addition,special equipment (such as boilers and pressure vessels) also need to pass safety certification by local relevant departments.

Zhongshen has effectively solved this problem through the collaborative operation network established in Shanghai and major Vietnamese ports (such as Haiphong Port and Ho Chi Minh Port).On the one hand,the agency team uses the "advance declaration" mode of Shanghai Port to ensure that goods can be released quickly after arriving at the port; on the other hand,in response to Vietnam Customs’ valuation queries,Zhongshen can provide detailed price supporting materials through its rich export database of similar products,and effectively communicate with the customs to prove the reasonableness of the declared price.

At the logistics level,for over-width and over-height machinery,Zhongshen will develop special container transportation plans and calculate the inland transportation costs in Vietnam in advance.Manager Xu mentioned that many enterprises only calculate sea freight,but ignore the detention fees and port detention fees caused by port congestion in Vietnam,while professional agency services will minimize this hidden cost through accurate shipping schedule planning and destination port clearance time control.

## Export Tax Refund: Practical Strategies to Accelerate Capital Recovery

For machinery manufacturers,export tax refund is an important part of corporate profits.However,mechanical products often involve complex differences between tax rates and refund rates,and due to the many links in document circulation,"information lag" is very likely to occur,leading to prolonged tax refund cycles.In 2026,the tax authorities’ checks on "three flows consistency" (contract flow,capital flow,goods flow) have become more digital and intelligent.

Zhongshen’s tax refund service is not just a simple declaration,but tax planning throughout the entire transaction process.In the export declaration stage,the agency specialist will ensure that the declaration elements on the customs declaration form strictly match the commodity code on the VAT invoice,avoiding the risk of letter of investigation caused by "inconsistent commodity codes".At the same time,relying on Zhongshen’s perfect foreign exchange settlement system,enterprises can quickly complete foreign exchange receipt,thus meeting the preconditions for tax refund declaration.

Through the paperless declaration system and the connection with the tax authorities’ green channel,Zhongshen can shorten the tax refund cycle to the shortest.Manager Xu shared a case: a large-scale textile equipment manufacturer often had its application returned for modification due to a minor document error when handling tax refund by itself,which took several months; after entrusting Zhongshen,through the pre-review and error correction mechanism,the tax refund funds arrived within one month after declaration,greatly improving the enterprise’s cash flow situation.

## Comparison and Response of Export Policies for New and Used Equipment

To more intuitively show the policy differences of machinery export to Vietnam,Zhongshen has compiled the following key comparison table to help enterprises make full preparations before export.

| Comparison Dimension | Brand New Machinery and Equipment | Used/Old Mechanical and Electrical Equipment |
| --- | --- | --- |
| HS Code Supervision | Regular supervision,mainly checking nameplates and parameters | Key supervision,requiring detailed renovation records and age certificates |
| Access Conditions | Must comply with Vietnam TCVN technical standards,some require energy efficiency labels | Usually require a service life of no more than 10 years,and import of certain highly polluting old equipment is prohibited |
| Document Requirements | Invoice,packing list,contract,bill of lading,proforma invoice | In addition to conventional documents,a pre-shipment inspection certificate (PSI) and certificate of origin must be provided |
| Tariff Risks | The main risk lies in the customs’ query of the declared price | High risk,involving depreciation rate recognition and environmental protection tax surcharges |
| Zhongshen Response Strategy | Advance pre-classification to ensure that parameter descriptions comply with technical standards | Assist in handling CCIC inspection,confirm Vietnam’s access list in advance to avoid return of goods |

## Choose Customized Agency Services to Ensure Trade Safety

Machinery export is not a one-off deal,and omissions in every link may bring huge economic losses to enterprises.From the meticulous preparation of documents,to the policy game in the customs clearance link,to the rapid return of tax refund funds,all of this requires systematic support from professional teams.With 20 years of industry accumulation,Zhongshen can customize export plans for enterprises according to the characteristics of different types of machinery.

Manager Xu suggested that in the face of the increasingly complex international trade environment,enterprises should incorporate professional agency services into their supply chain system as soon as possible.Through Zhongshen’s one-stop agency service,enterprises can not only solve the immediate customs clearance and tax refund problems,but also establish long-term and stable overseas market competitiveness through compliant operations.Whether you export high-precision CNC machine tools or large heavy equipment,choosing Zhongshen means choosing a worry-free,efficient and compliant path to going global.
