clearance and fund security.
In 2026,the domestic food consumption market continues to upgrade,and the import volume of olive oil and dairy products from Italy,Spain and other places grows steadily.Mr.Liang,who operates high-end food distribution in Suzhou,planned to import a batch of extra virgin olive oil from Italy at the beginning of the year.In actual operation,he found that food import is far from as simple as imagined: issues such as label filing,certificate of origin format,tariff quota applicability,and customs valuation are closely linked,and a slight carelessness will lead to port detention,return shipment or even administrative penalty.Such situations are highly representative in the import link,highlighting the value of professional agencies.
Zhongshen has been deeply engaged in import customs clearance at Shanghai Port for more than 20 years,and has handled tax declaration for various types of goods.Taking food as an example,the core of agency service is to transform scattered regulatory requirements into executable operation paths,identify risk points before declaration,respond quickly during inspection,and complete follow-up supervision connection after release.This full-process intervention model directly determines the smoothness of the tax payment link and compliance costs.

Document Pre-review: The Golden Window to Avoid Declaration Errors
The quality of documents directly determines customs declaration efficiency.After receiving the order,Zhongshen first conducts a systematic review of the trade documents provided by Mr.Liang.This link usually takes three working days,focusing on five types of documents:
- Whether the product name,specification and quantity on the commercial invoice and packing list are consistent and whether there are vague descriptions
- Whether the format of the certificate of origin meets the requirements of the latest free trade agreements and whether the visa date is within the validity period
- Whether the health certificate contains key information such as product batch number,production date and shelf life
- Whether the foreign language label sample has been converted for compliance in accordance with GB 7718 General Rules for Labeling of Prepackaged Foods
- Whether the overseas production enterprise has completed registration and filing with the General Administration of Customs and whether the registration number is valid
On the Italian supplier’s invoice initially provided by Mr.Liang,the product name of olive oil was only marked as "Extra Virgin Olive Oil" without indicating the acidity value and packaging specifications.The document review personnel of Zhongshen pointed out that in customs classification,the tariff codes of virgin olive oil are divided into two sub-items 15091000 and 15099000 according to the acidity,with a two percentage point difference in tax rates.By requesting a revision and asking the supplier to supplement the acidity test report and detailed specification instructions,the accurate classification code was finally determined,avoiding the tax repayment risk caused by subsequent classification disputes.
Label Compliance Pre-review
Food labels are the key inspection objects in the commodity inspection link.Zhongshen will review the draft of Chinese labels in advance to check whether the ingredient list,nutrition label and dealer information are complete.Since 2026,the supervision of imported food labels has become stricter,with detailed regulations on the rounding interval of the nutrition label and the labeling method of dietary fiber.In the initial draft of Mr.Liang’s olive oil label,the sodium content on the nutrition label did not meet the new regulations.Zhongshen proposed a modification plan during the pre-review stage,avoiding the container detention fees caused by label rectification after the goods arrived at the port.
Port Customs Declaration: Accurate Declaration and Tax Calculation
After completing the document pre-review,enter the formal declaration link.Zhongshen submits the customs declaration form through the Single Window system,and the declaration elements cover the three core aspects of classification,price and origin.The particularity of food import is that the customs will strictly review the freight and insurance premiums during the price review,especially for goods imported from Europe,where sea freight fluctuates greatly.

The key operations in the customs declaration link include:
- Accurately fill in the transaction terms,and distinguish the composition of dutiable value under different clauses such as CIF,FOB and C&F
- Reasonably allocate freight and insurance premiums,and retain real payment vouchers for verification
- Correctly apply the agreed tariff rate and enjoy tariff preferences through the certificate of origin
- Truthfully declare the quantity and weight of goods to avoid errors in filling in the statutory quantity and the second quantity
The contract terms of Mr.Liang’s olive oil were CIF Shanghai,but the invoice combined the freight and the value of goods.When declaring,Zhongshen separated the freight part based on the sea waybill and freight invoice to ensure a clear composition of the dutiable value.This operation played a key role in the subsequent customs price verification,avoiding questions caused by unclear price composition.Finally,the batch of goods applied the agreed tariff rate with the Italian certificate of origin,and the tariff rate was reduced from 12% to 5.5%,saving nearly 30,000 yuan in tax for this item alone.
Tax Calculation and Payment
After the customs system completes the document review,a tax payment voucher is generated.Imported foods involve tariffs and value-added tax,and some products also involve consumption tax.In 2026,the VAT rate remains 13%,but the customs has strengthened price review efforts.After receiving the tax voucher,Zhongshen will immediately check the tax calculation logic,focusing on checking whether the applicable tax rate for classification,the exchange rate for converting the dutiable value,and the preferential agreed tariff rate are accurate.After confirmation,the tax will be paid immediately through the electronic payment system to ensure that the goods enter the release process as soon as possible.
Commodity Inspection: Sampling Test and Label Rectification
Food import must go through the commodity inspection procedure.The main work of Zhongshen at this stage is to coordinate the inspection site,cooperate with sampling and follow up the test results.In 2026,the port has increased the sampling ratio of imported edible oil for items such as acidity,peroxide value and solvent residue,and the test period is about 7-10 working days.
Mr.Liang’s olive oil was selected for testing during the inspection.Zhongshen prepared the overseas test report of the same batch of products in advance and coordinated the laboratory to conduct the test first.At the same time,the customs inspector found that the label printing of two batches was blurred,and the font height of "virgin olive oil" in the ingredient list did not meet the standard requirement of 1.8 mm.Zhongshen immediately activated the label rectification plan,arranged a professional team to reapply compliant labels in the supervised warehouse,and applied for re-inspection after the rectification was completed.The whole process was completed within three days and did not substantially affect the pickup time.
Handling of Special Supervision Requirements
Some imported foods need to obtain the
| Operation Link | Common Risk Points | Zhongshen Response Measures | Time Impact |
|---|---|---|---|
| Document Pre-review | Classification errors,invalid certificate of origin | Establish a commodity database and verify the qualification of the visa institution in advance | Avoid 3-5 days of order return |
| Price Declaration | Unclear freight allocation,undeclared royalties | Assist in splitting freight and review technology licensing agreements | Reduce 1-2 weeks of verification |
| Label Review | Insufficient font height,incorrect ingredient ordering | Provide standard templates and pre-review Chinese labels | Save 2-3 days of rectification |
| Sampling Test | Exceeding indicator standards,missed inspection items | Pre-inspect overseas reports and coordinate laboratory expedited testing | Shorten the cycle by 5-7 days |
Case Review: Key Decisions from Port Detention to Smooth Release
Mr.Liang’s olive oil project was not smooth.Before the goods arrived at the port,the Italian supplier temporarily changed the packaging factory,resulting in the production batch number on the health certificate being inconsistent with the actual goods.If this error was not detected in time,it would directly lead to the inability to declare the goods.Zhongshen found the inconsistency of the batch number in the document review and recheck link,immediately notified Mr.Liang to contact the supplier to issue a correction letter and add an explanation on the health certificate.Due to timely handling,the goods were declared normally after arriving at the port without incurring port detention fees.
Another key node appeared in the customs price review link.The price review officials questioned the declared price of this batch of olive oil,believing that the import price of the same brand three months ago was lower than the current declared price.Zhongshen quickly retrieved the international market olive oil futures price trend and sea freight fluctuation data of the same period,and provided the price composition explanation issued by the Italian supplier to prove that the price difference was due to the increase in international raw material prices and freight.After two rounds of communication,the customs accepted the declared price and did not initiate the formal valuation procedure.
The entire project took 11 working days from arrival at the port to release,of which the test period accounted for 7 working days,and the actual customs clearance time was only 4 working days.For other batches of goods that Mr.Liang operated by himself before,the average customs clearance time was more than 15 working days,and additional costs were incurred due to label issues.
Implicit Value of Professional Agency
Import tax payment is not a simple tax calculation,but a comprehensive project involving commodity knowledge,regulatory understanding and port practical experience.The agency service of Zhongshen essentially builds a risk filter for enterprises.In the 2026 regulatory environment,the customs has stricter traceability requirements for food imports,and enterprises need to establish not only a single declaration capability,but also a continuous compliance system.
Through agency services,enterprises can focus their limited energy on supply chain management and market development,and hand over complex document processing,classification research,price negotiation and inspection response to professional teams.The efficiency improvement and risk avoidance brought by this division of labor model often far exceed the agency service fee itself.For small and medium-sized trading enterprises without full-time customs personnel,professional agency is almost a necessary condition to ensure the smooth operation of import business.
After the project was completed,Mr.Liang handed over all subsequent imported food businesses to Zhongshen for agency.This trust is based on the recognition of professional capabilities,and more from the re-recognition of compliance costs.In the import link,a successful risk avoidance may save potential losses dozens of times the agency fee.This is exactly the core value of professional agency services.
