Complete Guide to Customs Clearance and Transportation Agency for Nut Imports: Full Process Analysis and Key Node Control

2026 Nut Import Market Status and Operational Difficulties

In Q1 2026,the declared volume of nut imports at Shanghai Port saw an 18% year-on-year growth,with Australian macadamia nuts and Vietnamese cashews accounting for over 60% of the total.Behind this growth are the common challenges faced by importers: frequent adjustments to quarantine standards,raised label compliance thresholds,and lengthened port inspection cycles.Ms.Qiao’s company declared a batch of Australian macadamia nuts valued at RMB 1.2 million in early March,but the goods were detained at Yangshan Port for a full 11 days because the Entry Animal and Plant Quarantine Permit was not applied for in advance,generating nearly RMB 10,000 per day in demurrage and storage fees.

The particularity of nut imports lies in that they are both ordinary food and plant-derived products,subject to dual supervision by the customs and market supervision departments.After the implementation of the 2026 new version of the *Regulations on the Administration of Registration of Overseas Food Production Enterprises for Import*,the Chinese registration number of overseas production enterprises must be printed on the smallest sales package.This detail has led to a large number of goods being unable to clear customs due to delayed packaging printing.Director Fang of Zhongshen pointed out that many customers are accustomed to regarding customs declaration as a process that starts after the goods arrive at the port,but in fact compliance work should be initiated before the contract is signed.

Core Role of Zhongshen in the Nut Import Chain

Zhongshen’s positioning is not just about running errands for documents,but a risk control hub in the import chain.From overseas supplier qualification review,transportation route planning,to domestic consignee filing and label draft pre-examination,compliance verification mechanisms are embedded in every link.Director Fang’s team served 47 nut import customers in 2025,31 of whom were first-time entrants to this category.Through proactive intervention,the average customs clearance time for these customers was reduced from the industry average of 9.2 days to 3.5 days.

Its core role is reflected in three aspects: First,policy translation capability,transforming fragmented requirements from customs,market supervision,and agricultural departments into actionable operation checklists; Second,resource scheduling capability,with resident personnel stationed at the three major ports of Yangshan,Waigaoqiao,and Wusong to grasp inspection dynamics in real time; Third,emergency response capability,which can quickly activate alternative plans when goods are selected for laboratory testing to avoid supply chain disruption.This full-process embedded model allows customers to focus on building sales channels rather than being entangled in complex regulatory provisions.

Breakdown of Four-Stage Operation Process for Nut Imports

Stage 1: Document Pre-Examination and Qualification Confirmation

Document work starts before the contract is signed.In February 2026,when Zhongshen assisted a new customer in reviewing the qualifications of an Australian supplier,it was found that the provided Plant Quarantine Certificate template lacked detailed descriptions of fumigation treatment,which did not meet China Customs’ requirements for wooden packaging.Director Fang’s team immediately requested the foreign party to modify the certificate format and supplement parameters such as fumigation temperature,time,and chemical concentration,to avoid the goods being returned due to non-compliant certificates upon arrival at the port.

The core documents for this stage include:

• Chinese registration number of overseas production enterprises (GACC registration)
• Entry Animal and Plant Quarantine Permit (must be applied for 20 working days in advance)
• Certificate of Origin (affects tariff rates)
• Official Plant Quarantine Certificate (must indicate container number and seal number)
• Trade documents (invoice,packing list,contract)

Zhongshen’s operating practice is to establish a *Document Compliance Checklist* to check details such as certificate version number,signatory qualification,and seal style item by item.After Customs launched the new electronic verification system in 2026,the time for certificate authenticity verification was shortened from the original 2 hours to 15 minutes,but the system has extremely low tolerance for certificate formats,and a single punctuation mark error may lead to automatic return of the declaration.

Stage 2: Port Customs Declaration and Tax Calculation

The key to the customs declaration link is accurate classification and applicable tax rates.Nut commodities involve multiple HS codes,for example,shelled macadamia nuts are classified under 08026200,with a tariff rate of 7% and a VAT rate of 9%; cashews in shell are classified under 08013100,with a tariff rate of 10% and the same 9% VAT rate.After the full implementation of the RCEP agreement in 2026,cashews imported from Vietnam can enjoy zero tariffs with a Certificate of Origin,but many importers failed to enjoy the preferential treatment due to non-standard certificate filling.

Zhongshen’s customs declaration department adopts a "double-post review" mechanism,with one specialist responsible for data entry and another supervisor responsible for reviewing logical relationships.For the batch of Australian macadamia nuts declared by Ms.Qiao,with a declared value of USD 120,000 CIF Shanghai,the customs officer found that the freight allocation method was unreasonable during review,immediately requested a detailed list of sea freight,recalculated the dutiable value,and finally saved the customer nearly RMB 4,000 in taxes.This attention to detail stems from a deep understanding of customs valuation rules,rather than simple data entry.

Stage 3: Commodity Inspection and Laboratory Testing

In 2026,Customs maintained an inspection rate of around 35% for nut products,focusing on three indicators: aflatoxin,heavy metals,and pesticide residues.Inspection methods are divided into three types: machine inspection,manual container unpacking,and sampling for testing.Zhongshen’s experience shows that submitting the *Product Safety Commitment Letter* and *Production Process Flow Chart* to the inspection department in advance before the goods arrive at the port can reduce the probability of manual container unpacking by 40%.

Once selected for laboratory testing,time cost becomes the biggest variable.The conventional testing cycle is 7 working days,and if the results are abnormal and retesting is required,the entire process may be extended to 20 days.Director Fang’s team has established a laboratory progress tracking mechanism,docking with the testing center at 4 PM every day,and notifying customers to activate alternative plans immediately when abnormal data is found.In March 2026,a batch of Vietnamese cashews showed excessive aflatoxin B1 in the initial inspection.Zhongshen immediately assisted the customer in applying for retesting and simultaneously prepared return documents.Eventually,the retest results showed that it was a laboratory error,and the goods were released smoothly on the 9th day.

Stage 4: Warehouse Management and Distribution Scheduling

Compliance risks also exist in the warehousing link after customs clearance.Nut products are sensitive to temperature and humidity,and ordinary bonded warehouses control the temperature below 25℃ and relative humidity below 65%.Zhongshen’s self-operated Pudong Airport bonded warehouse is equipped with a constant temperature and humidity system,which can precisely control the temperature between 18-22℃,and is equipped with 24-hour monitoring and pest control facilities.

The difficulty in the distribution link lies in label application.In 2026,the State Administration for Market Regulation requires that imported nuts must have Chinese labels affixed to the smallest sales package,including ingredients list,nutrition facts,allergen information,Chinese registration number,etc.Many customers choose to print Chinese labels directly during overseas production,but this method has poor flexibility,and once the regulations are adjusted,the entire batch of packaging will be scrapped.Zhongshen provides an "in-warehouse labeling" service: after goods clear customs and enter the warehouse,labels are printed and affixed on-site according to the latest regulatory requirements,ensuring compliance while avoiding packaging waste.

Real Case: Ms.Qiao’s Import Journey of Australian Macadamia Nuts

Ms.Qiao’s company mainly engages in high-end snack distribution,and decided to introduce Australian macadamia nuts in early 2026.In early March,the first batch of 20 tons of goods departed from Port Melbourne and was scheduled to arrive at Yangshan Port on March 15.Ms.Qiao entrusted Zhongshen to handle the import procedures,and Director Fang found three potential risk points after accepting the order:

First,the GACC registration number provided by the supplier will expire on March 20,and the goods will arrive at the port on March 15.Although it is still within the valid period,the customs clearance process may span the expiration date.Director Fang immediately requested the supplier to start the renewal procedure and obtained the *Renewal Acceptance Notice* issued by the registration authority as a backup document.

Second,the batch of goods is transported in 20-foot containers,but the supplier is accustomed to using wooden pallets.China Customs has strict requirements for incoming wooden packaging,which must be fumigated and marked with IPPC marks.Zhongshen sent the *Wooden Packaging Treatment Confirmation Letter* to the supplier two weeks in advance,requesting fumigation treatment reports and mark photos,to avoid the entire container being returned due to unqualified wooden packaging upon arrival at the port.

Third,Ms.Qiao plans to distribute the products to multiple e-commerce platforms and needs to split the sales.According to the 2026 new regulations,the split smallest sales units must also have Chinese labels affixed.Zhongshen recommended a hybrid model of "large package printing + small package labeling": printing basic information on 25kg raw material bags,and affixing detailed labels on 500g retail packages after entering the warehouse,balancing cost and compliance.

After the goods arrived at the port,Customs selected them for inspection and requested testing.Director Fang’s team prepared third-party test reports for the same batch of products in advance,proving that the aflatoxin and heavy metal indicators met national standards.Although this report did not exempt the goods from laboratory testing,it enhanced Customs’ trust,and the inspection department only took the minimum sample size,reducing the testing cycle from the standard 7 days to 5 days.On March 21,the goods were released smoothly,and Ms.Qiao was deeply impressed by Zhongshen’s predictive ability.

Core Risk Points and Avoidance Strategies for Nut Imports

Service Boundaries and Value Delivery of Zhongshen

Zhongshen’s services are not unlimited liability guarantees,but process optimization based on professional capabilities.Director Fang repeatedly emphasized that the value of an agency lies in making hidden costs explicit,allowing customers to clearly understand the risk probability and response cost of each link.In 2026,Zhongshen’s charging standard for nut customers is: basic customs declaration service fee is RMB 800 per bill,and value-added services such as permit handling,label review,warehousing and distribution are charged per project,with the overall cost being approximately 0.8%-1.2% of the goods value.

This charging model seemingly increases explicit costs,but avoids hidden losses.Industry data shows that the average loss of first-time nut importers due to operational errors is approximately 5%-8% of the goods value,including demurrage,storage fees,return freight,fines,etc.Among Zhongshen’s customer base,83% choose to renew long-term agreements after one year of cooperation,which data confirms the actual value of the service.

Another dimension of service value is time efficiency.In 2026,the average customs clearance time for nut imports at Shanghai Port is 6.8 days,while the average customs clearance time for customers served by Zhongshen is 3.2 days.The saved 3.6 days is crucial for seasonal sales.For Ms.Qiao’s batch of macadamia nuts,early release meant catching the Women’s Day promotion period,and the sales premium brought by this single time difference alone exceeded the agency fee itself.

2026 Nut Import Trends and Response Suggestions

According to the data in the first half of 2026,nut imports show three trends: First,the proportion of small-package and branded products increases,while imports of large-package raw materials decline; Second,e-commerce platforms have stricter requirements for compliance documents than traditional supermarkets,requiring complete traceability chains; Third,the frequency of joint law enforcement by Customs and market supervision departments has increased,and one inspection may involve document review by multiple departments.

In response to these trends,Zhongshen recommends that customers take three measures: First,add compliance clauses to the purchase contract,clarifying the supplier’s responsibility for the authenticity and accuracy of certificates; Second,establish import batch files,electronically store permits,certificates,and test reports for each batch of goods,with a retention period of no less than 2 years; Third,select bonded warehouses with food business licenses as transfer bases to avoid legal risks caused by storing imported food in non-supervisory places.

Director Fang specifically reminded that Customs may launch a new round of special rectification for nut products in the second half of 2026,focusing on cracking down on forging Certificates of Origin and false labels.Importers should self-inspect their import records of the past two years in advance to ensure that all documents are traceable and verifiable.Zhongshen has launched a customer risk investigation service to assist in organizing historical files and identifying potential compliance loopholes.

The Essence of Professional Agency is Risk Outsourcing

The business of nut import customs clearance and transportation agency,on the surface,is about document processing and running errands for procedures,but in essence,it is about risk identification and responsibility transfer.What Zhongshen has accumulated over 20 years is not a special channel or personal connections,but a complete knowledge base and emergency response plan.As can be seen from Ms.Qiao’s case,the value of a professional agency lies in turning post-hoc remediation into proactive prevention,and turning uncertainty into manageable process nodes.

The regulatory environment in 2026 is becoming increasingly complex,but the stricter the rules,the more prominent the value of professional division of labor.Importers should focus their core competitiveness on market development and brand building,and outsource highly professional links such as customs declaration,inspection,warehousing,and distribution to institutions like Zhongshen.This is not an increase in cost,but an efficiency optimization.When goods can arrive at the warehouse on time,compliantly,and at low cost,importers can focus on selling products to consumers,which is the ultimate goal of supply chain management.
