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

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.
