# How to Amortize Freight for Export Agency? 2026 Practical Guide

## 2026 Vietnam Electronic Products Export: Core Pain Points and Solutions for Freight Amortization

In 2026,as a core electronic industry undertaking country among RCEP member states,Vietnam’s export demand for smartphone accessories and smart home devices has increased by 18% year-on-year.Many foreign trade enterprises in Shanghai choose the agency export mode,but they often encounter pitfalls in freight amortization due to differences in Vietnam’s customs policies.Ms.Gu is a senior agency consultant at Zhongshen.Last year,she assisted a wireless headphone manufacturer in solving freight amortization problems: the client initially allocated freight based on cargo value,which led to the freight proportion of some SKUs exceeding the 10% limit stipulated by Vietnam Customs,and the client was required to supplement a third-party report,resulting in a 3-day delay in customs clearance.

### Core Policy of Vietnam’s Electronic Products Trade: Binding of Freight,Tariff and Tax Refund

In 2026,Vietnam Customs has clear requirements for dutiable value calculation of electronic products: the proportion of freight included in CIF price shall not exceed 10% of the cargo value.If it exceeds the limit,a freight reasonableness certificate issued by SGS Vietnam is required; meanwhile,the export tax refund link requires that freight documents must fully match the customs declaration and bill of lading,otherwise they cannot be included in cost deduction.The core value of Zhongshen is that,targeting Vietnam’s policy details,it converts freight amortization from "post-event accounting" to "pre-event planning",and coordinates both customs declaration and tax refund links simultaneously.

## Module Decomposition of Zhongshen Agency Service: Exclusive Solution for Vietnamese Market

Targeting the freight amortization demand of Vietnam’s electronic products export,Zhongshen divides the service into four core modules,each module designs targeted solutions for local policy barriers:

### Module 1: Vietnam Customs Compliance Audit of Freight Documents

**Vietnam-specific Requirements**: Freight invoice must include the endorsement of the shipping company’s Vietnam branch,detailed actual weight/volume of the cargo,and the full route from the port of departure to the destination port in Vietnam; for multimodal transport (e.g.Shanghai→Guangzhou→Ho Chi Minh),a full through bill of lading is required instead of segmented bills of lading.

**Risk Points**: Invoices provided by some freight forwarders do not have shipping company endorsement,or weight details do not match the customs declaration,which leads to Vietnam Customs refusing to include freight in dutiable value and thus increasing tariff cost.

**Zhongshen’s Solution**: Ms.Gu’s team has established a whitelist of shipping companies recognized by Vietnam Customs (including Maersk,Hapag-Lloyd Vietnam Branch).After clients submit freight documents,the team completes the review of three core elements within 1 working day: endorsement validity,weight/volume matching,and route completeness.Since 2025,it has helped 32 electronic product clients avoid customs clearance delay caused by non-compliant documents.

### Module 2: Freight Allocation Matching for Dutiable Value

![How Can Export Agency Freight Amortization Cut Costs? 3 Steps to Implementation](https://cndpic.sh-zhongshen.com/uploads/tradepics/96KJhTVjmiaGI.webp)

**Vietnam-specific Requirements**: The dutiable value of electronic products under RCEP needs to be subdivided by HS code,freight proportion for goods under different codes shall be calculated separately,and the freight proportion of a single SKU shall not exceed 10%.

**Risk Points**: If freight is allocated based on overall cargo value,the freight proportion of SKUs with large weight but low value (such as headphone packaging boxes) will easily exceed 10% and incur extra tariff; if allocated by weight,SKUs with high value but low weight (such as headphone chips) may have undercounted freight,which affects tax refund deduction.

**Zhongshen’s Solution**: According to the latest HS code catalog of Vietnam Customs,Supervisor Hong’s team splits clients’ electronic products by code,and adopts the mixed allocation method of "weight proportion + volume proportion" -- heavy accessories are allocated by weight,large-volume packaging are allocated by volume,ensuring that the freight proportion of a single SKU is controlled between 8% and 10%.In the first quarter of 2026,this solution helped clients reduce tariff by an average of 12%.

### Module 3: Freight Amortization Accounting Linked to Tax Refund

**Vietnam-specific Requirements**: A "freight amortization schedule" is required for export tax refund,which must list the freight amount of each SKU,corresponding bill of lading number and customs declaration number,and must be consistent with the customs declaration data in Vietnam’s tax system.

**Risk Points**: If the amortization schedule does not match the customs declaration data,the Vietnamese tax authority will require clients to resubmit documents,and the tax refund arrival time may be extended to more than 45 days.

**Zhongshen’s Solution**: Zhongshen’s tax refund team and agency team work synchronously,and complete pre-audit of the freight amortization schedule before customs declaration,ensuring that the SKU code and freight amount in the schedule fully match the customs declaration.Since 2026,for the Vietnam electronic product export tax refund processed by this team,the average arrival time has been shortened from the industry average 30 days to 18 days.

## Comparison of Different Freight Amortization Methods in Vietnamese Market

| Amortization Method | Compliance with Vietnam Customs | Tax Refund Compatibility | Zhongshen Optimization |
| --- | --- | --- | --- |
| Allocation by cargo value | Easy to exceed 10% limit,low compliance | Schedule easily conflicts with customs declaration,poor compatibility | Only used for single SKU with value matching weight/volume |
| Allocation by actual weight | Heavy SKUs easily exceed the limit,medium compliance | Schedule is easy to match,medium compatibility | Adjust weight after splitting by HS code |
| Allocation by volume | Large-volume SKUs easily exceed the limit,medium compliance | Schedule is easy to match,medium compatibility | Used in combination with weight allocation |
| Zhongshen Customized (HS code + mixed proportion) | Single SKU proportion controlled at 8%-10%,high compliance | 100% match between schedule and customs declaration,high compatibility | Adjust dynamically according to Vietnam’s RCEP policies |

## Key Actions of Zhongshen to Improve Customs Clearance and Tax Refund Efficiency

Targeting the pain points of freight amortization in the Vietnamese market,Zhongshen improves service efficiency through the following actions:

- Update and synchronize the latest Vietnam Customs freight policy to clients 7 working days in advance,and has updated RCEP freight calculation rules 3 times in 2026
- Review the matching of freight documents and tariff codes simultaneously during document pre-audit,to avoid "finding problems after customs declaration"
- Pre-connect with Vietnam Customs system during customs clearance,submit freight amortization schedule in advance to shorten customs review time

Mr.You is a customer manager at Zhongshen,he once served a client exporting smart watches: after adopting Zhongshen’s customized amortization solution,the customs clearance time was shortened from 48 hours to 24 hours,the tax refund arrival time was shortened from 35 days to 16 days,and the client directly saved 12,000 RMB in tariff cost.

## Customized Service: Matching Your Products and Target Country

In addition to Vietnam,Zhongshen’s freight amortization solution is also applicable to other RCEP member countries such as Thailand and Malaysia -- different countries have different requirements for the proportion of freight included in dutiable value and document requirements.If you export mechanical accessories,textiles and other products,Mr.You states that we can provide free freight amortization scheme evaluation and design an exclusive scheme based on the target country’s policies.
