Offshore Company Exports to Vietnam Facing Obstacles? Zhongshen with 20 Years of Experience Solves Customs Clearance and Tax Refund Problems

Vietnam Market 2026: New Variables and Long-standing Problems for Offshore Company Exports

In the first quarter of 2026,Vietnam’s manufacturing PMI has remained steadily in the expansion range,and the procurement demand for electronic components,machinery and equipment,and chemical raw materials has increased sharply year-on-year.A precision mold enterprise from the Yangtze River Delta that exports via a Hong Kong offshore company had its goods detained at Ho Chi Minh Port for 17 days,because Vietnam Customs questioned the format of the certificate of origin declared by the non-resident enterprise and required supplementary proof of the equity structure of the investor.Although the order was eventually released,it missed the customer’s production line launch window,and the penalty for breach of contract was equivalent to 60% of the profit of the entire order.

Such scenarios occur repeatedly in the trade chain of offshore companies exporting to Vietnam.The Guidelines for Determining the Origin of Imported and Exported Goods revised by the Vietnamese Ministry of Industry and Trade at the end of 2025 explicitly lists offshore structure enterprises as "key inspection objects" and requires the provision of ultimate beneficial owner penetration documents.At the same time,the State Bank of Vietnam has strengthened the review of foreign exchange sources,and a slight mistake in the collection path of offshore companies will trigger a compliance alert.In a case handled by Manager Ly in March,a customer’s 400,000 US dollar payment was frozen for three weeks because the intermediary bank involved in the payment route between the offshore account and the Vietnamese buyer’s paying bank was on the sanctions list.Behind these policy tightenings is Vietnam’s attempt to close loopholes that allow evasion of anti-dumping duties and access to free trade agreement preferences through offshore structures.

Zhongshen’s Response Logic: Turning Policy Gaps into Operational Space

The core contradiction of offshore companies exporting to Vietnam lies in the conflict between commercial convenience and regulatory penetration.The original intention of enterprises to choose an offshore structure is to optimize taxation,isolate risks,and allocate funds flexibly.However,the regulatory logic of Vietnam Customs and tax authorities requires penetration to the ultimate actual controller to ensure that the trade essence is consistent with the declared information.The value of Zhongshen lies in building a conversion channel between the policy systems of the two regions with 20 years of accumulated practical experience.

In Manager Ly’s team’s operation manual,there are more than 200 records of rejection reasons for declaration documents submitted by offshore companies to Vietnam Customs,and high-frequency problems are concentrated in three categories: the address of the offshore company in column 8 of the certificate of origin does not match the place of registration,the commercial invoice does not mark the ultimate beneficial owner,and the packing list does not list the information of the production factory.Zhongshen’s solution is not simply to supplement documents,but to complete "declaration element pre-confirmation" before shipment.The specific approach is to generate a set of simulated declaration documents during the customer’s stocking stage according to the latest document review rules of Vietnam Customs,and identify risk points in advance.In the fourth quarter of 2025,this pre-confirmation mechanism helped customers avoid 83% of document-related inspections.

Document Module: Penetrative Declaration Requirements Unique to Vietnam

Rules for Marking the "Dual Identity" of Certificate of Origin

Vietnam Customs requires that for FORM E or C/O issued by offshore companies,the name of the offshore company and the information of the actual manufacturer must be displayed in column 7 at the same time,and "Actual Manufacturer: [Factory Name]" must be marked in English in the remarks column of column 8.Many enterprises directly use generic templates and only fill in offshore company information,which leads to the documents being regarded as "incomplete" during customs clearance.More seriously,if the place of registration of the offshore company is not within the member states of the China-ASEAN Free Trade Agreement,Vietnam Customs may refuse to grant tariff preferences.

Zhongshen’s approach is to prepare two drafts of the certificate of origin simultaneously when the customer places a production order: one is issued under the regular offshore company letterhead,and the other is issued under the actual factory letterhead.A version with a higher passing rate is selected according to the industry of the Vietnamese customer and historical customs clearance records.For high-value goods with sensitive HS codes,an additional "Producer Declaration" is prepared,which is sealed by the factory to confirm that the product is fully originating,as supplementary evidence when customs raises questions.In the textile machinery export case handled by Manager Ly in February 2026,it was precisely relying on this pre-prepared producer declaration that the explanation was completed within 24 hours when customs questioned the origin of the core components of the equipment,avoiding a 14-day port detention and inspection.

Ultimate Beneficial Owner Disclosure Mechanism for Commercial Invoices

The Anti-Commercial Fraud Law revised by Vietnam in 2025 requires that when an offshore company acts as the seller,the name of the ultimate beneficial owner or the holding company must be clearly marked on the commercial invoice.This requirement hits the core of privacy protection of offshore structures.Many enterprises worry that disclosure will trigger tax retrospective or shareholder information leakage.

Zhongshen’s compromised solution is to use a standardized statement in the invoice remarks column: "Ultimate Beneficial Owner: [English Name of Holding Company],Registration No.: [Registration Number]".This not only meets the disclosure requirements of Vietnam Customs,but also avoids directly exposing individual shareholder information.At the same time,Zhongshen will assist customers in preparing a "Beneficiary Information Protection Statement",stating that the disclosure scope is only for customs supervision purposes,and affixed with the official seal of the offshore company.After this document is filed with the Vietnam Customs system,it does not need to be submitted repeatedly for subsequent customs clearance of similar goods,reducing the processing time per shipment from an average of 5 days to 1 day.

Customs Clearance Module: Strategies to Crack High Inspection Rate for Offshore Companies

Statistics from 2025 show that the inspection rate of goods from offshore companies by Vietnam Customs is 22 percentage points higher than that of regular enterprises,mainly concentrated in two categories: price underreporting and origin fraud.Inspections are often triggered when the declared price is more than 15% lower than the reference price in the customs database,or there is ambiguity in HS code classification.

Zhongshen’s response is not simply to increase the declared price,but to establish a "price rationality proof package".This proof package contains three core documents: first,the real purchase contract between the offshore company and the domestic factory,showing the cost composition; second,the "target price description" provided by the Vietnamese buyer,proving that the low price is based on a long-term cooperation agreement; third,the market price research report issued by a third-party institution.In the LED lamp export case handled by Manager Ly in January 2026,relying on this proof package,he convinced the customs valuation officer in 30 minutes during the price inquiry interview,avoiding 30% of the valuation-based supplementary tax.

For HS code classification risks,Zhongshen provides "pre-classification consultation" services.Before shipment,product technical parameters,drawings,and function descriptions are submitted to the Vietnam Customs classification department to obtain written classification opinions.This opinion is valid for 12 months,and can be directly referenced during customs clearance of similar goods during the period,reducing the inspection rate from the industry average of 35% to less than 5%.In 2025,Zhongshen obtained more than 120 pre-classification opinions for customers,involving a cargo value of more than 80 million US dollars.

Tax Refund Module: Operational Path for Offshore Companies to Get Tax Refund Within 90 Days

The biggest obstacle to offshore company export tax refund is the "subject mismatch" in the foreign exchange verification process.The Chinese tax authority requires that the foreign exchange collection subject must be consistent with the consignor on the export customs declaration,but after the offshore company collects the foreign exchange,the funds often do not return directly to the domestic factory account,but remain abroad through related party transactions.This causes the tax authority to be unable to match the foreign exchange flow,and the tax refund application is put on hold.

The "closed capital flow" scheme designed by Zhongshen focuses on connecting the three links of offshore company foreign exchange collection,domestic factory tax refund,and foreign exchange compliance.The specific operation is: after the offshore company receives the payment from the Vietnamese customer,it remits the corresponding RMB amount to the domestic factory account through a compliance path within 15 working days,and clearly marks "Vietnam project payment,corresponding customs declaration number XXX" in the remarks column.At the same time,Zhongshen assists the factory in preparing a "Cross-border Related Party Transaction Statement",explaining the related relationship between the offshore company and the factory,and attaching the proof of overseas fund arrival and the domestic bank exchange settlement memo.

Under this mechanism,after the tax refund materials are submitted,the focus of the tax authority’s review shifts from "whether foreign exchange has arrived" to "whether the trade is real".Through pre-communication with the competent tax authority,Zhongshen files the trade model of the offshore structure and obtains "whitelist" treatment.In the first quarter of 2026,among the customers served by Manager Ly’s team,the average tax refund cycle is 87 days,and the fastest one arrived 63 days after declaration,which is nearly half shorter than the industry average of 150 days.

Efficiency Improvement: Quantitative Comparison of Customs Clearance Time and Tax Refund Speed

The data is based on statistics of 127 offshore company export to Vietnam businesses served by Zhongshen from the fourth quarter of 2025 to the first quarter of 2026.The key to improving customs clearance efficiency is changing post-event remediation to pre-event prevention.Manager Ly’s team establishes a "Vietnam Customs Clearance File" for each customer,records historical declaration data,customs document review preferences,and inspection records,forming a dynamic knowledge base.When processing new orders,the system automatically matches historical cases and warns of potential risk points.This model reduces the cost of repetitive trial and error to a minimum.

Risk Avoidance: Advanced Planning for Vietnam Policy Changes in 2026

The Vietnamese Ministry of Finance plans to launch the "Electronic Invoice System 2.0" in the third quarter of 2026,requiring all export trade documents to be stored on-chain.This means that for offshore companies,the traditional room for manual document supplementation and post-event explanation will be greatly reduced.Zhongshen has already connected with Vietnam’s designated technical service providers in advance,and completes pre-on-chain processing of customers’ trade data during the shipment stage,ensuring that electronic documents meet the new regulation format when generated.

Another potential risk point is that the Vietnamese Ministry of Industry and Trade is planning to impose an additional "anti-tax avoidance review fee" on high value-added products exported through offshore companies.Although the policy has not yet been implemented,Zhongshen has started preparing "economic substance proof" documents for customers,including the office location,employees,and business decision-making records of the offshore company in the place of registration,to prove that it is not a pure shell company.Manager Ly suggests that newly established offshore companies in 2026 should retain substantive operation traces in the place of registration to avoid being identified as a "conduit company" by Vietnam Customs and refused customs clearance.

Customized Service Path for Choosing Zhongshen

The complexity of offshore company exports to Vietnam determines that standardized services cannot be effective.Zhongshen provides three cooperation modes: for customers with annual export volume exceeding 5 million US dollars,a full-time operation team is dispatched to the customer’s office to realize integrated embedded services covering documents,logistics,foreign exchange,and tax refund; for small and medium-sized customers,"key node hosting" service is provided,customers handle procurement and production by themselves,and Zhongshen takes over three high-risk links: Vietnam customs clearance,foreign exchange settlement,and tax refund declaration; for new customers who tentatively enter the Vietnamese market,we launch a "full-process first order" experience service,undertaking the whole process from document preparation to tax refund arrival,and charging based on results.

Manager Ly specially reminds that the supervision of offshore companies by Vietnam Customs in 2026 shows a trend of "loose at the front end,tight at the back end",that is,customs clearance may be released quickly,but the intensity of post-clearance audit has increased.Zhongshen keeps a complete trade chain evidence package for all customers,including production records,quality inspection reports,logistics tracks,and email communication records,with a storage period of 7 years,ensuring that when Vietnam Customs conducts post-clearance audit,a full set of explanatory materials can be provided within 48 hours.This "sufficient preparation,fast response" mechanism is the key to avoiding tax recovery and fines.

If your company is currently exporting to Vietnam through an offshore company,or plans to set up an offshore structure to explore the Vietnamese market,Zhongshen’s customized services can convert compliance costs into competitive advantages.From the document design of the first shipment to the annual tax refund planning,each link has quantifiable efficiency improvement and risk control solutions.The opportunity window of the Vietnamese market is still expanding,but the game rules have changed.The value of a professional agency is to allow enterprises to keep up with the pace,avoid pitfalls,and not miss orders while complying with the new rules.
