Exporting to the US facing anti-dumping sanctions? Full-chain breakdown of compliant transshipment trade operations

Destination Port Certification and Transit Route Design

The US Customs and Border Protection (CBP) has strengthened Certificate of Origin verification in 2026,requiring general cargo transshipment to match third-country processing vouchers.When Zhongshitong handled a case for a Suzhou machinery factory,it was found that CNC machine tools transshipped via Vietnam needed to simultaneously provide: Form AJ Certificate of Origin issued by the Vietnam Ministry of Industry and Trade,processing production records showing 30% value addition by the Vietnamese factory,and a final processing declaration issued by the US importer.

Core Parameters for Transit Country Selection

For transshipment via Southeast Asian countries,attention must be paid to changes in local export control policies.In 2026,Thailand added a filing system for electronic equipment transshipment,while Malaysia requires a transit stay period of no more than 15 days for machinery products.During operations,simultaneous verification is required: the transit country is not on the US sanctions list,local customs manifest data matches AMS filing exactly,and the transit port has ISO-certified loading and unloading capabilities.

Anti-dumping Warning and Tariff Avoidance Paths

The US Department of Commerce expanded the anti-dumping duty list to 217 product categories in 2026,with steel product rates reaching 132% and furniture products facing an 89.7% additional tax.Transshipment trade avoidance schemes must meet three hard criteria: the HS code on the third-country Certificate of Origin matches the physical goods exactly,the transit logistics trajectory is verifiable,and the commercial invoice price complies with transfer pricing rules.

Analysis of Real-World Pitfall Cases

Ms.Shi,a Ningbo hardware tools exporter,encountered US Section 232 tariffs.Zhongshitong designed a transshipment plan via Port Klang,Malaysia: product assembly and repackaging were completed in Malaysia to obtain an MAFTA Certificate of Origin.The key operation was re-declaring the HS code as 9403.20 (finished product),evading the 7326.19 (steel product) tariff heading,saving $370,000 in tariff expenditure.This plan required simultaneous completion of: ISO system certification for the Malaysian factory,an audit report on the proportion of processing costs,and GPS traceability of the logistics trajectory.

Export Tax Rebate Optimization Operation Guide

Transshipment trade rebates require establishing a triple voucher chain: domestic factory VAT special invoices,third-country transit clearance documents,and final destination port receipt proof.In 2026,the Shanghai Tax Bureau strictly scrutinizes transshipment trade rebates,focusing on the following verifications:

• Logical matching of foreign exchange payment vouchers with transit bill of lading dates
• Applicability of tax rebate rates based on the original product code before transshipment
• Error between collection amount minus transit fees and customs declaration amount ≤ 5%

Zhongshitong’s Shanghai port practical cases show that for chemical products transshipped via Singapore,an SGS composition test report must be attached when submitting the SPETA Certificate of Origin,ensuring tax rebate approval time is compressed from the usual 45 days to 18 days.

Collection Security and Capital Chain Guarantee

Transshipment trade involves dual exchange rate risk points: transit country currency fluctuations and extended US dollar settlement cycles.In 2026,it is recommended to adopt:

• Locking forward exchange rates: Immediately lock a 90-day forward settlement upon completion of the transit link
• Staged payment terms: 30% deposit collected domestically,70% balance paid directly by the final buyer
• Sinosure special policies: Covering political risks in transit countries and buyer bad faith

Demurrage Trap Prevention Measures

US port demurrage charges rose to $320/day in 2026.Transshipment requires guarding against the superposition of triple fees: origin port excess container usage fees + transit port storage fees + destination port container detention fees.In a scheme designed by Zhongshitong for a Shenzhen electronics exporter,the shipping company was required to sign a full-route transit time guarantee agreement,with excess costs borne by the carrier.This clause saved the enterprise 230,000 RMB in hidden costs.

Core Value of Global Synergy Network

Zhongshitong Shanghai Headquarters links up with Qingdao and Shenzhen ports to implement remote declaration,completing via 37 global agent nodes: expedited issuance of Cambodian Certificates of Origin,compliance background checks on Thai factories,and pre-clearance at Mexico Gulf ports.A mechanical and electrical export case showed that when US Customs requested additional qualification documents for a Vietnamese processing factory,the Ho Chi Minh City agent completed on-site verification within 4 hours,avoiding cargo detention at the Port of Long Beach.

Transshipment cases handled by Manager Ge’s team last year show that unverified transit channels pose three fatal risks: forgery of third-country export licenses,conflict between transit port customs data and AMS filings,and retrospective anti-circumvention investigations by the destination country.An on-site factory verification mechanism for transit country agents must be established to ensure every transshipment order possesses a traceable compliance closed loop.
