Wenzhou Plastic Bags Transshipment Trade 2026 Practical Key Points Sorting

Manager Wei of a plastic bag factory in Wenzhou gritted his teeth and switched a batch of orders bound for the US to direct sea shipping last year.But when the goods arrived at the Port of Los Angeles,the anti-dumping tax bill issued by the customs left him stunned: for an order with a goods value of 1.2 million yuan,the tariff alone deducted 307,000 yuan.After excluding logistics and production costs,there was almost no profit."If I had known that transshipment trade could bypass this barrier back then,I wouldn’t have lost so much." Manager Wei later heard from peers that some manufacturers transited via Malaysia,and the tariff was directly reduced to less than 3%,but he has no idea about the operation approach and is afraid of stepping on compliance minefields.

In the Wenzhou plastic bag industry in 2026,confusions like Manager Wei’s are by no means isolated.As Europe and the US continue to tighten anti-dumping policies on Chinese plastic bags,coupled with the release of dividends from free trade agreements between Southeast Asian markets and Europe and the US,transshipment trade is becoming a "breakthrough key" for many export enterprises.However,transshipment trade is not simply "unloading at another port".From transit location selection to customs declaration and inspection,every step hides cost traps and compliance risks.This article combines practical cases of local Wenzhou enterprises to sort out the core points of transshipment trade,helping you avoid pitfalls and save costs.

Core Drivers of Wenzhou Plastic Bag Transshipment Trade in 2026

"Detour" Demand Under Anti-dumping Barriers

According to the latest data in March 2026,the US maintains an anti-dumping duty rate of 22.8%-28.5% on Chinese plastic bags,while the EU continues to apply an average rate of 18.3%,squeezing the profit margin of some enterprises to less than 5%.Mr.Dai,head of a medium-sized plastic bag factory in Wenzhou,calculated: "Last year,we sent 10 containers to Germany,each paying nearly 100,000 yuan more in tariffs.That’s 1.2 million yuan a year,equivalent to the profit of 2 fewer containers."

Transit Dividends in Southeast Asian Market

In 2026,free trade agreements between Malaysia,Vietnam and the US,EU have entered a deepening stage.Among them,the Digital Economy Partnership Agreement (DEPA) between Malaysia and the US clearly stipulates that the tariff on plastic bags originating in Malaysia exported to the US is reduced to 0-3.5%; the EU-Vietnam Free Trade Agreement (EVFTA) reduces the tariff on related products to less than 3%.At the same time,there are 3-4 weekly shipping routes from Wenzhou to Port Klang in Malaysia and Ho Chi Minh Port in Vietnam,with a voyage of only 5-7 days,and the transit timeliness is controllable.

Mr.Tan from Zhongshen has been in the industry for more than 20 years and has contacted nearly 100 Wenzhou plastic bag enterprises.He summarized the core drivers of transshipment trade:

• The US and EU continue to impose anti-dumping duties on Chinese plastic bags (average tax rate 15%-28%)
• Southeast Asia (Malaysia,Vietnam) has signed free trade agreements with Europe and the US,reducing tariffs to 0-5%
• Wenzhou has excess plastic bag production capacity and needs to expand low-cost export channels

3 Key Operation Links of Wenzhou Plastic Bag Transshipment Trade

1.Transit Location and Logistics Route Selection (Key Point)

Transit locations are not the cheaper the better.Mr.Tan reminds that priority should be given to regions with "free trade agreements + mature logistics networks + standardized customs supervision".In 2026,there are three commonly used transit locations for Wenzhou enterprises: Port Klang in Malaysia,Ho Chi Minh Port in Vietnam,and Bangkok Port in Thailand.Among them,Port Klang,as the largest container port in Southeast Asia,has the highest transit efficiency,with an inspection rate of only 5.2%,2.3 percentage points lower than that of Ho Chi Minh Port.

The selection of logistics routes should be combined with goods value and timeliness.The following is the cost comparison of plastic bag transportation from Wenzhou to the US/EU in 2026:

2.Compliance Key Points for Customs Declaration and Inspection

Many enterprises think that transshipment trade only needs to change the bill of lading,but that is not the case.In 2026,European and American customs are becoming stricter in the review of the origin of transshipped goods.Mr.Tan gave an example: last year,a Wenzhou enterprise shipped plastic bags to Malaysia,directly changed to Malaysian packaging and sent them to the US.As a result,the US customs found that the actual place of origin of the goods was China.Not only were the goods detained,but the enterprise was also fined 50,000 yuan.

There are three compliance key points:

• The certificate of origin (FORM E or FORM RCEP) of the transit location must be provided,and the processing value-added rate of the goods in the transit location must reach more than 30% (for example,repackaging and labeling in Malaysia,and the processing cost accounts for 30% of the goods value)
• Plastic bags must meet the environmental protection standards of the destination country: the US requires compliance with FDA food contact standards,and the EU requires passing REACH SVHC 219 items testing.The transit location customs will inspect these reports for the second time
• The "source of goods" on the customs declaration form should be truthfully filled in as "Wenzhou,China",while the "place of origin" is filled in as the transit location to avoid false declaration

Mr.Dai stepped on this pitfall last year: "We did not do processing value-added in the transit location before,directly changed a label and declared customs.As a result,we were stuck in Malaysia for 10 days.Later,we asked Zhongshen for help to supplement the packaging and processing certificate before we were released smoothly."

3.Connection of Foreign Exchange and Tax Refund

For foreign exchange receipt and payment in transshipment trade,attention should be paid to the "consistency of three flows": capital flow (foreign exchange is paid directly from the destination country to the domestic account),goods flow (bill of lading shows the transit location),invoice flow (domestic suppliers issue VAT invoices to export enterprises).In 2026,the State Administration of Foreign Exchange has stricter verification of foreign exchange in transshipment trade.Mr.Tan reminds: "Do not use third-country accounts to idle foreign exchange,otherwise it will be judged as an abnormal transaction and affect subsequent tax refunds."

In terms of tax refund,the transshipment trade is consistent with the general export tax refund process,but additional bills of lading from the transit location,certificate of origin,and processing value-added certificate are required.Manager Wei’s tax refund was delayed for 3 months last year due to incorrect foreign exchange path: "At that time,we asked our US customer to pay the money to a Hong Kong account.As a result,the foreign exchange bureau considered the capital flow abnormal.Later,according to Zhongshen’s suggestion,we asked the customer to pay directly to our domestic foreign exchange account,and supplemented the transit location certificate,before we successfully got the tax refund."

Common Risks and Avoidance Methods of Wenzhou Plastic Bag Transshipment Trade

• Risk 1: High inspection rate of transit location customs→In the first half of 2026,the inspection rate of plastic bags at Ho Chi Minh Port,Vietnam rose to 12.5%,and some enterprises were returned because their goods packaging did not meet the requirements.Avoidance method: Confirm the local packaging standards with the transit location agent in advance (for example,Vietnam requires that the outer box of plastic bags must be printed with the transit location origin mark),and provide complete testing reports and processing certificates to reduce the inspection probability
• Risk 2: Logistics timeliness delay→In April this year,the route from Wenzhou to Port Klang was delayed for 7 days due to the congestion of the Suez Canal,resulting in order breach of contract for an enterprise.Avoidance method: Choose shipping companies with fixed transit routes (such as Maersk,Mediterranean Shipping),and reserve a buffer period of 3-5 days to avoid delay of urgent orders
• Risk 3: Tariff policy change→In the second half of 2026,the EU may adjust the tariff standard for plastic bags from Southeast Asia,and some enterprises are worried that policy changes will affect profits.Avoidance method: Pay attention to the update of free trade agreements between the transit location and the destination country every quarter.Zhongshen will regularly push policy warnings to customers,and at the same time suggest that enterprises sign a "tariff change supplementary agreement" with the transit location agent to clarify the cost sharing after policy changes

Future Trends of Wenzhou Plastic Bag Transshipment Trade in 2026

Mr.Tan believes that the core competitiveness of transshipment trade in the future will shift from "tax avoidance" to "compliance + efficiency": "For example,some enterprises have begun to build small packaging factories in the transit location to increase the processing value-added rate,and at the same time connect with the local logistics network to shorten the transit timeliness." In addition,with the advancement of RCEP regional economic integration,Wenzhou plastic bag enterprises can also layout the Southeast Asian local market through transshipment trade.For example,the demand for e-commerce packaging in Malaysia increases by 12% every year,and many enterprises leave part of the transshipped containers for local sales,increasing additional profits.
