2026 Key Operation Points and Notes for Transit Trade Export to the US

2026 Status Quo and Common Challenges of Transit Trade Export to the US

In the first half of 2026,a batch of wireless headphone orders exported to the US by a Shanghai electronic accessories trader via a third-party transit channel was detained at the Port of Los Angeles for 3 days,incurring nearly USD 2,000 in extra storage fees,as the trader failed to confirm in advance the US Customs’ requirements for origin marking of transit goods.Data over the same period shows that the US consumer market’s demand for Asian-made electronic products and household goods still maintains an annual growth rate of around 5%,but enterprises engaged in transit trade export to the US are facing three major practical challenges:

• U.S.Customs and Border Protection (CBP) has tightened audits on the authenticity of transit logic,and false transit contracts are easily identified as "tariff evasion";
• The "substantial transformation" requirements for some categories are ambiguous,making it difficult for enterprises to judge whether goods meet tax refund conditions;
• Mismatches between documents and logistics records have pushed the probability of export tax refund applications being rejected by China’s tax authorities up to 12%.

Core Service Value of Zhongshen for US Transit Trade

Zhongshen,which has been deeply engaged in the foreign trade agency industry for over 20 years,has built a full-link service system of "policy pre-research - document review - customs clearance tracking - tax refund follow-up" targeting the regulatory characteristics of US transit trade in 2026.Mr.Chen,director of Zhongshen,stated: "Our core advantage is not ’walking clients through the process’,but anticipating key inspection points of US Customs in advance.For example,in the second quarter of 2026,CBP focused on inspecting the authenticity of tripartite agreements for ’household goods transit’,we notified our cooperative clients to supplement suppliers’ processing contracts one week in advance,avoiding customs clearance delays for 3 orders."

Disassembly of Core Service Modules of US Transit Trade Agency

I.Document Processing: Matching the Latest CBP Compliance Requirements

The 2026 updated CBP transit trade document rules clearly require: tripartite trade agreements (Chinese supplier,transit trader,US importer) and certificates of origin marked with "transit goods" must be provided,and the shipper/consignee on the bill of lading must be consistent with the agreement.The number of cases where some enterprises use "double-title bills of lading" to simplify processes and are identified as "tariff evasion" by CBP increased by 8% year on year.

Zhongshen’s response plan is implemented by the document team led by Ms.Luo,who has more than 10 years of experience in US document processing:

• Complete preliminary review within 24 hours after receiving client materials,focusing on checking the "closed transit logic loop" of the tripartite agreement (such as the logistics connection of suppliers delivering goods to transit traders,then transit traders delivering goods to US importers);
• Provide document templates that meet CBP requirements to avoid rejections caused by ambiguous expressions;
• For sensitive categories such as electronic products,additionally review "product model change records" to ensure alignment with transit logic.

II.US Customs Clearance: Focusing on "Substantial Transformation" Audit

The US defines "substantial transformation" of transit goods as: goods undergo "functional change" or "added value increase of more than 30%" in the transit country (2026 updated standard).If only simple packaging and labeling are carried out,goods will be deemed as directly exported,and original tariffs shall be paid (tax rates for some categories are as high as 25%).

The customs clearance team led by Manager Chang (directly connected with 3 core local US customs brokers) improves customs clearance efficiency through three measures:

• Complete "substantial transformation assessment" 3 days before goods shipment,and issue an assessment report including processing contracts and added value calculation sheets;
• Establish a CBP inspection early warning mechanism.If the inspection rate of a certain category (such as smart home products) rises from 10% to 20%,notify clients to supplement "product function test reports" in advance;
• Open "express customs clearance channels" for major ports such as Los Angeles and New York,cutting normal customs clearance time from 7 days to less than 3 days (data for the first half of 2026).

III.Export Tax Refund: Synchronizing Logistics and Foreign Exchange Records

In 2026,China’s tax authorities require that export tax refunds for transit trade must provide complete logistics tracking records (shipping orders,manifests,destination port receipts),and the interval between foreign exchange receipt time and goods departure time shall not exceed 30 days.The tax refund application rejection rate of some enterprises reaches 15% due to incomplete logistics records.

The financial team led by Ms.Yin optimizes processes through the "logistics - foreign exchange - tax refund" linkage mechanism:

• Launch the "transit trade logistics tracking system",which synchronizes full-process information of goods from shipment in China to receipt in the US in real time,and automatically generates logistics records required by tax authorities;
• Initiate tax refund applications within 1 working day after foreign exchange is received,and communicate with tax authorities in advance to confirm the completeness of materials;
• With optimized tax refund processes for transit trade,normal tax refund time is cut from 2-3 months to less than 1.5 months (industry average is 2.2 months).

Key Notes for Transit Trade Export to the US

• Tripartite trade agreements shall clearly state the "reason for transit" (such as US importers’ requirements for supplier qualifications) to avoid ambiguous expressions;
• Certificates of origin shall be issued by official agencies of the transit country and marked with the words "transit goods";
• "Processing contracts + payment vouchers" shall be retained for goods processing links in the transit country,to be used as proof of "substantial transformation";
• Logistics records shall include full bills of lading covering "China - transit country - the US" to avoid chain breaks;
• Foreign exchange shall be paid directly by US importers to Chinese suppliers’ accounts,third-party payment on behalf is prohibited.

Selection Suggestions for Customized Agency Services

In the second half of 2026,US regulation on transit trade will further focus on "supply chain transparency",with obvious differences in requirements for different categories (for example,electronic products require FCC certification,and household goods require ASTM certification).Zhongshen will formulate exclusive transit plans according to clients’ product characteristics (such as mechanical accessories,textiles),target ports (such as Miami,Seattle) and order volumes:

For example,for small-batch electronic product orders,we provide a fast response channel of "Hong Kong as the transit country + Port of Los Angeles"; for large-batch household goods orders,we coordinate storage resources in the transit country in advance to complete simple assembly (to meet substantial transformation requirements).Director Chen stated: "Our service is not a ’standardized package’,but ’one-to-one matching’ - after all,each enterprise’s transit demand comes with different compliance risks and efficiency pain points."
