Practical Guide to the Whole Process of Freight Forwarding for Export of Construction Machinery Parts from Ningxiang to Vietnam

Current Situation of Vietnam Market and Export Blockers for Ningxiang Enterprises

In 2026,Vietnam’s infrastructure construction investment is expected to exceed 28 billion US dollars,and the demand for construction machinery parts continues to grow steadily.As an important supporting base for equipment manufacturing in China,Ningxiang’s hydraulic parts,transmission parts,precision castings and other products have obvious cost-performance advantages in the Vietnamese market.However,in actual operation,more than ten Ningxiang manufacturing enterprises contacted by Supervisor Ling are generally stuck in three links: the technical standard inspection cycle of mechanical products by Vietnam Customs lasts 5-7 working days,the withdrawal and query rate of FORM E certificate of origin increased by 40% year-on-year,and the average arrival time of export tax refund is delayed to more than 60 days.These practical problems directly squeeze the cash flow of enterprises,and some orders even face the risk of breach of contract due to delivery delay.

More specifically,the newly revised Administrative Measures for Quality Management of Imported Mechanical and Electrical Products issued by the Ministry of Industry and Trade of Vietnam in 2026 requires that all construction machinery parts must provide type test reports issued by Vietnam-recognized laboratories or Product Quality Compliance Statement issued by China Customs.This document needs to be submitted simultaneously with 12 types of documents including customs declaration,invoice,packing list,certificate of origin and other documents.A batch of hydraulic valve groups in charge of Ms.Zhong was classified as "high-pressure equipment requiring additional certification" by Vietnam Customs due to the deviation of HS code classification of the product,resulting in the detention of the whole batch of goods at Ho Chi Minh Port for 12 days,with total detention fee and storage fee exceeding 30,000 RMB.

Core Value of Zhongshen’s Export Agency Service

Zhongshen has been operating Vietnam routes since 2006,and has gone through the whole process from border small-volume trade to standardized customs clearance under the RCEP framework.The operation team led by Mr.Fu found that the crux of Ningxiang enterprises’ export to Vietnam lies not in product competitiveness,but in insufficient response speed to changes in Vietnam Customs policies.In 2026,Vietnam Customs fully launched the V5.0 version of the electronic port system,with 37 more declaration fields than the old version.Many enterprises encountered declaration rejection for their first shipment.Zhongshen completed system connection three months in advance and maintained the declaration accuracy above 99.2%.

The core difference lies in the intervention timing.Ordinary freight forwarders usually start operation after getting documents when goods are loaded on board,while Zhongshen launches the pre-audit mechanism when inspecting goods in the workshop of Ningxiang factories.The customs declaration team led by Supervisor Zhū will check product model,specification and material on site,and conduct pre-classification according to the latest Tariff Notes for Mechanical Parts released by Vietnam Customs in 2026,ensuring 100% accuracy of HS code.This pre-service solves problems before shipment and avoids rectification costs after arrival at the port.Among the 47 Ningxiang enterprises served last year,no shipment was detained at the port due to document problems.

Document Preparation Module: Compliance Points of Vietnamese FORM E Certificate of Origin

Origin Standard Determination and Material Traceability

Vietnam Customs’ review of FORM E has been refined to the raw material level.Although the 2026 RCEP rules of origin cumulation have relaxed standards,Vietnam Customs requires complete raw material purchase invoices,processing procedure descriptions and cost breakdowns.A batch of gear boxes produced in Ningxiang handled by Manager Tú encountered this problem: the product used Japanese imported bearing steel.Although forging,machining and heat treatment were completed in China,Vietnam Customs considered that "raw materials are not of Chinese origin" and required additional certificates in accordance with Product Specific Rules (PSR).Zhongshen retrieved the quality certificate from the steel mill,import customs declaration and heat treatment process records,built a complete evidence chain,and finally obtained tariff reduction.

At the operational level,Zhongshen has established a FORM E visa database for Ningxiang’s export to Vietnam,which records the raw material composition,processing procedures and value-added proportion of each product.New orders can quickly judge whether they meet origin standards by comparing historical data.For non-compliant products,enterprises are advised to adjust the supply chain or prepare supplementary documents in advance to avoid passivity after arrival at the port.In the first quarter of 2026,the rejection and query rate of FORM E certificates handled by Zhongshen was controlled within 1.5%,far lower than the industry average of 12%.

Commodity Classification Pre-ruling and Risk Avoidance

Vietnam Customs launched a new version of intelligent auxiliary system for commodity classification in 2026,and the classification logic for mechanical parts is more strict.Before shipment of Ningxiang enterprises,Zhongshen will submit a classification pre-ruling application to Vietnam Customs to obtain official code confirmation.This process takes 15 working days,but ensures zero risk of subsequent customs clearance.For a batch of sealing products handled by Supervisor Líng,the pre-ruling result has a tax refund rate 3 percentage points higher than the code originally declared by the enterprise,and the single shipment obtained an additional tax refund of 18,000 RMB.

Customs Clearance Service Module: Vietnam Customs AEO Certification Channel

Pre-processing of Technical Standard Inspection

Vietnam Customs’ technical inspection of construction machinery parts focuses on safety performance indicators.According to the new regulations in 2026,pressure vessel parts need to provide TÜV or equivalent institutional certification,and transmission parts need to meet Vietnamese national standard TCVN 8298.Zhongshen has established cooperation with Vietnam-designated laboratories,conducts on-site sampling and sealing at Ningxiang factories,and sends samples directly for inspection,compressing the inspection cycle from 20 days to 8 days.Mr.Fu’s team will review product technical documents in advance and put forward rectification suggestions based on differences from Vietnamese standards to ensure one-time approval.

For ordinary parts that do not require laboratory testing,Zhongshen uses the Product Quality Compliance Statement issued by China Customs to speed up customs clearance.Supervisor Zhū has specially sorted out statement format templates recognized by Vietnam Customs,guides the quality department of Ningxiang enterprises to fill in the form in a standardized manner,and avoids declaration rejection due to format problems.With the green channel of AEO advanced certification enterprises,the customs clearance time of such goods can be controlled within 1.5 working days.

Inspection Rate Control and Abnormal Handling

In 2026,Vietnam Customs set the inspection rate of first-time imported products at 100%,and the inspection rate of repeatedly imported products at about 30%.Zhongshen helps Ningxiang enterprises achieve "one inspection,multiple reuse" by establishing a product file library.After the first batch of goods passes inspection smoothly,subsequent batches can apply for inspection exemption or reduced inspection proportion.For a certain type of hydraulic pump operated by Ms.Zhōng,after the first batch passed inspection,all 17 subsequent batches were exempt from inspection,saving 3 days of inspection time per batch.

In case of abnormal inspection,Zhongshen has resident personnel in Ho Chi Minh and Haiphong,who can arrive at the scene within 2 hours.Supervisor Líng once handled a case where Customs suspected underreporting of commodity value.The resident personnel submitted the cost accounting sheet of Ningxiang factory,raw material purchase contract and export price comparison data of the same industry on the spot,completed the explanation in the Customs office,and avoided the risk of transferring the goods to the anti-smuggling department.

Tax Refund Service Module: Electronic Solution to Accelerate Capital Turnover

Automatic Collection of Tax Refund Declaration Data

In 2026,the State Taxation Administration of China launched an upgraded version of "paperless" export tax refund,which requires automatic matching of data such as customs declaration,invoices and exchange settlement receipts.The tax refund auxiliary system developed by Zhongshen automatically captures data from the electronic port after goods are loaded on board and generates the tax refund declaration form.After Manager Tú checks and confirms,it is directly pushed to the tax bureau system,reducing the 3-day workload of traditional manual input to 2 hours.After a Ningxiang enterprise used this system,the preparation time of tax refund declaration was compressed from 5 days to half a day.

Aiming at the unique mode of "batch shipment,centralized exchange settlement" in the Vietnamese market,Zhongshen designed an intelligent splitting function for exchange settlement receipts.The system automatically splits foreign exchange receipts according to the customs declaration amount of each batch and matches the corresponding exchange settlement verification slip,solving the tax refund problem when multiple shipments correspond to one foreign exchange.Among the clients served by Supervisor Zhū,there is an enterprise that exports more than 20 shipments to Vietnam every month.After using this system,the accuracy of tax refund declaration reaches 100%,and there is no more non-subjective intentional violation risk.

Tax Refund Cycle Compression and Capital Planning

Zhongshen compresses the tax refund cycle of Ningxiang enterprises exporting to Vietnam from 60 days to within 45 days through three measures.First,complete the tax refund declaration within 24 hours after the customs declaration is cleared,3 days earlier than conventional operation; second,establish a green communication mechanism with the competent tax authorities to implement "review upon arrival" for key export enterprises in Ningxiang; third,provide tax refund arrival early warning service,so that enterprises can plan capital use in advance.Data tracked by Mr.Fu’s team shows that from January to April 2026,the average tax refund cycle of served Ningxiang enterprises is 42 days,and the fastest one only takes 38 days.

For enterprises with tight cash flow,Zhongshen also provides tax refund pledge financing scheme.With the declared tax refund certificate,cooperative banks can advance 80% of the tax refund in advance,and the enterprise bears a small amount of interest to solve the urgent problem.In a business coordinated by Supervisor Líng,it only took 7 days for the enterprise to get the bank advance from tax refund declaration,and capital efficiency was greatly improved.

Empirical Evidence of Improvement in Customs Clearance Efficiency and Tax Refund Speed

Zhongshen reviewed the business of Ningxiang exporting to Vietnam served in 2026,and data comparison shows obvious optimization.With the traditional freight forwarding mode,it takes an average of 18 days from factory loading to delivery to Vietnamese customers,of which the customs clearance link accounts for 7 days; with Zhongshen’s pre-service mode,the total time is shortened to 12 days,and the customs clearance link is compressed to 3 days.In terms of tax refund,the average time from export to tax refund arrival in the traditional mode is 65 days,while Zhongshen’s standardized process is stable within 45 days.

A Ningxiang hydraulic parts enterprise in charge of Ms.Zhōng exported 4.2 million US dollars of goods to Vietnam in the first quarter of 2026.After using Zhongshen’s service,it saved 180,000 RMB in port detention fees compared with the same period last year,obtained 3.2 million RMB of tax refund funds in advance,and reduced financial costs by 220,000 RMB.These data confirm the practical value of process optimization.

Customized Service Selection and Action Suggestions

For Ningxiang enterprises exporting to Vietnam,there are great differences in product types,trade terms and customer qualifications,which require matching different service combinations.Zhongshen provides three customized solutions: standardized customs clearance service for conventional parts,full follow-up service for high-value equipment,and annual framework agreement service for long-term stable orders.Supervisor Zhū suggests that for enterprises with annual export volume exceeding 5 million US dollars,the annual agreement is the most cost-effective,which can enjoy fixed rate and exclusive customer service; enterprises with many scattered orders are suitable for standardized services charged by shipment.

In terms of specific operation,enterprises contact Zhongshen 15 days before shipment,provide product technical data,trade contracts and customer information,and Zhongshen will issue Operation Proposal for Export to Vietnam within 3 working days,listing the document list,time nodes and cost details.Manager Tú particularly emphasizes that Vietnam Customs policies are adjusted slightly every quarter.Starting from the second quarter of 2026,some products need to provide additional carbon emission statements,and getting such information in advance can avoid being caught unprepared.

For Ningxiang enterprises that are considering independent customs declaration,Mr.Fu made a calculation: cultivating a customs declarant familiar with the Vietnamese market requires an annual salary of at least 150,000 RMB.Plus system investment and travel costs,the annual fixed expenditure exceeds 250,000 RMB.While Zhongshen charges by shipment,with an average cost of 3,000-5,000 RMB per shipment.The total cost of 50 shipments is even lower,and enterprises do not need to bear the risk of policy changes.This asset-light operation mode is especially suitable for small and medium-sized manufacturing enterprises.

Choosing Zhongshen is essentially choosing a set of Vietnam export solutions tested by 20 years of actual combat.From the workshop of Ningxiang factory to the warehouse of Vietnamese customers,each link has clear operating standards and emergency plans.Supervisor Líng finally reminds that there are many opportunities in the Vietnamese market in 2026,but compliance requirements are becoming stricter.Professional division of labor allows enterprises to focus on their main business,and handing over complex customs clearance and tax refund affairs to a dedicated team is the fundamental way to improve efficiency.
