Interpretation of 2026 New Policy for Zhoushan Export Tax Refund Agency: Adjustment of Refund Rates and Compliance Challenges

Disassembly of Core Policy Points

In early 2026,Zhoushan Customs and tax authorities jointly released the Implementation Plan for Export Tax Refund Facilitation Reform in Zhoushan Area of Zhejiang Pilot Free Trade Zone,which directly changed the capital circulation rhythm of local foreign trade enterprises.When interpreting the policy,the project department of Zhongshen found that the new policy is not a simple adjustment of figures,but a reconstruction of the declaration logic.

Point 1: Digital Acceleration of Export Tax Refund in Zhoushan Free Trade Zone

Starting from March 1,2026,all export enterprises in Zhoushan Area must switch to the "refund upon departure" electronic declaration system.The system connects with port logistics data.Once goods leave the port,customs declaration information will be automatically pushed to the tax authority.A ship parts factory where Mr.Fan works conducted a test and found that the original average tax refund cycle of 45 days can now be shortened to 12 working days at the fastest.However,the system has extremely high requirements for document matching.If the data deviation among customs declaration form,input VAT invoice and foreign exchange verification sheet exceeds 0.5%,manual review will be triggered,and the return rate reached 23% in the first month.

Point 2: Structural Adjustment of Tax Refund Rates for Marine Industry

As a national-level ship and offshore engineering equipment base,the 2026 edition of Export Tax Refund Rate Library clearly raises the refund rate of 12 categories of goods including offshore engineering platform modules and deep-water aquaculture equipment from 13% to 17% for Zhoushan.Meanwhile,the refund rate for traditional processed fishery products is lowered by 2 percentage points.The marine biotech company run by Mr.Shang originally planned to expand fish meal export.After calculation,it found that most of the profit was eroded by the rate reduction,so it urgently adjusted its direction and shifted production capacity to marine probiotic preparations,which just fall into the high refund category.This structural adjustment means that enterprises must re-evaluate their product line layout.

Point 3: Upgraded Intensity of Compliance Inspection

The 2026 special inspection plan of Zhoushan Municipal Taxation Bureau shows that the random inspection ratio in the field of export tax refund has been increased from 5% to 15%,focusing on three types of transactions: "first declaration of high-refund goods","single ticket amount exceeding 5 million yuan",and "complex supply chain hierarchy".Blockchain traceability technology is introduced into inspection methods,which can penetrate and verify the authenticity of input invoices of third-tier suppliers.An offshore engineering equipment export order of Mr.Wu was suspended due to the invalidated invoice of the second-tier supplier that was not handled in time,and the capital chain was almost broken.

Opportunities and Challenges Faced by Enterprises

Opportunity Window

• Shortened tax refund receipt cycle: The digital channel reduces the average receipt time by 60%,directly improving the cash flow of enterprises.A private shipyard in Zhoushan with an annual export volume of 300 million yuan can release about 14 million yuan of working capital throughout the year at this speed.
• Tax rate preference for characteristic industries: The refund rate for offshore engineering equipment has been raised by 4 percentage points,which is equivalent to an additional 400,000 yuan of tax refund for every 10 million yuan of export.For the shipbuilding industry with a general profit margin of 8%-12%,this is a tangible profit supplement.
• Port logistics synergy effect: The Comprehensive Bonded Zone of Zhoushan Port implements the policy of "tax refund upon entering the zone".Goods can apply for tax refund once they enter the bonded warehouse,without waiting for actual departure.The oil trading company run by Ms.Lai used this policy to shorten the capital occupation cycle by 18 days.

Challenge Pressure

• Higher document compliance threshold: The automatic comparison function of the system requires the information of customs declaration form,invoice,contract and bill of lading to be completely consistent.Even differences in punctuation may be judged as abnormal.The small error tolerance space in the manual processing era has completely disappeared.
• Increased system operation complexity: The new system requires triple authentication of tax UKEY,electronic port card and data signature certificate installed on the enterprise side.The operation interface involves 17 modules,and the learning cycle for ordinary financial personnel is at least one month.
• Higher inspection risk: Under blockchain traceability technology,the tax defects of suppliers will be transmitted to exporters.Many local ship parts enterprises in Zhoushan rely on processing by small workshops in other regions,and the invoice compliance of these suppliers has become an invisible bomb.

Implementation Path of Zhongshen’s Agency Services

Facing the adaptation pain of Zhoushan’s foreign trade enterprises under the new policy,Zhongshen has transformed its 20 years of customs clearance experience into implementable service modules,which are not simply filling in forms on behalf of enterprises,but embedded in the whole process of enterprise export.

Path 1: Digital Declaration Process Trusteeship

The technical department of Zhongshen has developed the "Zhoushan Export Tax Refund Intelligent Pre-examination System",which connects with the enterprise ERP,automatically captures the data of customs declaration forms and invoices before formal declaration,simulates the comparison rules of the tax system,and identifies matching errors in advance.After Mr.Fan’s parts factory accessed the system,the declaration return rate dropped from 23% to 1.2%.At the specific operation level,the agency team will check the accuracy of commodity code classification in advance.Zhoushan’s characteristic products such as marine crankshafts,anchor chains,offshore cranes,etc.often have fuzzy classification areas.A wrong code selection may lead to a difference of 4-6 percentage points in the tax refund rate.Zhongshen’s customs affairs consultants will combine the material,purpose and working principle of the product,give the optimal classification scheme against the Tariff Annotation,and issue a written classification proposal for retention and future reference.

Path 2: Customized Tax Refund Scheme for Marine Industry

In response to the dividend of the raised tax refund rate for Zhoushan’s offshore engineering equipment,Zhongshen has designed the "product split tax refund strategy".Taking a marine ranch platform project as an example,the total package contract amount is 120 million yuan,among which the tax refund rates of platform structural parts,mooring system and aquaculture net cage are 17%,13% and 9% respectively.The agency team assisted the enterprise to split the contract into three sub-items,signed separate procurement and sales agreements,and made the high refund part declared independently,with the overall tax refund amount 1.86 million yuan more than the unified package declaration.At the same time,Zhongshen will assist enterprises to prepare supporting materials proving that "products belong to the national key supported marine equipment catalog",including classification society certificates,technical parameter specifications,expert review opinions,etc.to cope with the substantive audit of the tax bureau.

Path 3: Compliance Risk Control System Construction

Zhongshen’s risk control department issues the Supplier Tax Health Scan Report for Zhoushan clients every month,using public data of the tax system to check the invoice violation records,tax arrears and credit ratings of upstream enterprises in the past two years.Mr.Wu’s offshore engineering equipment order found the tax arrears risk of the second-tier supplier in the scan,and the loss was avoided after the supplier was replaced urgently.In terms of inspection response,Zhongshen provides "full-process accompanying inspection service".From the issuance of inspection notice by the inspection bureau,the agency team will station in the enterprise,assist in sorting out business chain evidence,writing situation descriptions,and communicating technical details with inspectors.In April 2026,Mr.Shang’s biotech company was selected for random inspection.Zhongshen’s agency team sorted out a complete evidence chain of R&D,production and sales in three days,and the inspection bureau finally confirmed compliance and granted normal tax refund.

Practical Suggestions for Zhoushan Enterprises

Under the 2026 Zhoushan export tax refund policy environment,the most urgent action for enterprises is to complete the internal data standardization transformation.It is recommended to immediately set up a cross-departmental team,led by the finance department,and jointly participated by customs,sales and procurement departments,to unify the basic data dictionary such as commodity names,specifications and models,measurement units,etc.to ensure that the same set of data language is used throughout the process from contract signing to customs declaration and export.Meanwhile,tax compliance review should be added in the supplier access link,requiring suppliers to provide nearly one year’s tax payment certificate and invoice use list,so as to block tax risks before transactions occur.Zhongshen can provide free data standardization diagnosis services for Zhoushan enterprises,and issue a rectification list on site.Although the investment in this basic work is small,it determines the smoothness of all subsequent declaration work.
