# 2026 Complete Guide to Nuts Import Customs Declaration Process Analysis and Key Node Control

## I.2026 Nuts Import Market Pattern and Customs Clearance Difficulties

China’s nut consumer market is expected to reach 260 billion yuan in 2026,with import dependence exceeding 65%.Cashews from Vietnam,almonds and pecans from the United States,macadamias from Australia,and Thai dried mango with mixed nuts form the main source matrix.As the core hub of the Yangtze River Delta,Shanghai Port undertakes 43% of China’s total nut import throughput.In actual operation,enterprises do not simply face document submission,but systematic challenges covering four dimensions: customs classification,phytosanitary,label compliance and heavy metal residue.Especially the revised *Administrative Measures for Inspection and Quarantine of Imported Nuts* issued by the General Administration of Customs of China at the end of 2025 increased the aflatoxin sampling rate from 5% to 15%,and added ethylene oxide residue testing,which directly extended the average customs clearance cycle by 3-5 working days.A batch of California almonds handled by our supervisor last year was detained at the port because the processing method description on the phytosanitary certificate was vague,and the port required a supplementary heat treatment temperature curve,resulting in extra port detention costs of nearly 10,000 yuan.

## II.Positioning of Zhongshen in the Nut Import Chain

Zhongshen is not just a simple customs brokerage firm,but a compliance architect running through the upstream and downstream of the supply chain.We have connected four independent systems: the Customs Single Window,Commodity Inspection ECIQ System,Foreign Exchange Monitoring System and Tax Export Rebate Platform,turning originally scattered nodes into a predictable and controllable process.The core role is reflected in three levels: pre-risk research and judgment,we verify whether the overseas producer is registered in China and whether the product meets the latest national standards at the contract signing stage; process node control,accurately calculate each time window from arrival to release; emergency plan reserve,activate response plans for unexpected situations such as abnormal inspection,excessive test results,non-compliant labels,etc.This positioning determines that our relationship with customers is not principal-agent and execution,but a cooperative body that shares risks and information.

## III.Complete Process Disassembly of Nuts Import Customs Declaration

### 1.Document Pre-audit and Access Qualification Confirmation

This stage sets the tone for the entire import.Core documents include certificate of origin,phytosanitary certificate,health certificate,producer’s registration number in China,Chinese and English label samples and nutrition composition test report.From 2026,all phytosanitary certificates must state compliance with ISPM No.12,and must be fully consistent with the first six digits of the HS code on the certificate of origin.Zhongshen’s intervention in this link is to establish a pre-audit list mechanism: customers only need to provide scanned copies,and we will complete comparison and verification with the customs database within two working days.Early last year,a Thai customer served by our supervisor planned to import mixed nuts,we found in advance that the "no additives" claim on the packaging lacked a corresponding test report,and stopped the shipment in time,avoiding the risk of being returned due to false publicity after arrival.

### 2.Port Customs Declaration and Classification & Price Assessment

Classification disputes for nut products focus on three characteristics: whether sugar is added,whether it is roasted,and whether it is shelled.The tariff difference between 0802.90 (unshelled almonds) and 0802.12 (shelled roasted almonds) is 8 percentage points,and customs will refer to the contemporaneous international market transaction price for price assessment.Zhongshen’s practice is to prepare a transaction price explanation letter in advance,attach international futures price screenshots and freight breakdown,and actively guide the price assessment direction.In 2026,customs launched a new generation of risk parameter system,the probability of automatic price verification for first-time import enterprises is as high as 70%.Through pre-communication with the customs price information database,we have reduced this probability to less than 15%.When filling in the customs declaration form,the specification column must accurately include three parameters: particle diameter,processing technology,packaging specification.Any omission may lead to declaration rejection.

### 3.Commodity Inspection and Laboratory Testing

This is the most volatile link.Port inspection is divided into three levels: document verification,appearance inspection,and sampling for testing.Appearance inspection focuses on mildew,insect damage and foreign matters; sampling testing focuses on aflatoxin B1,heavy metals (lead,cadmium,mercury),pesticide residues (68 items in total) and the newly added ethylene oxide.Zhongshen’s response strategy is to establish a testing whitelist mechanism,cooperate with CNAS-accredited laboratories in advance,and reduce the testing cycle from the conventional 7 working days to 4 working days.In an Australian macadamia project handled by our supervisor,the sampled cadmium content was 0.21mg/kg (the national standard limit is 0.2mg/kg).We immediately started the retest procedure,and simultaneously provided the soil test report from the overseas producer.It was finally determined as abnormal background value in the border area,and the single batch was released,avoiding more than one million yuan in loss from whole-batch return.

## IV.Typical Case: Supervisor Zeng’s Vietnam Cashew Import Project

In March 2026,a Shanghai snack e-commerce client served by Supervisor Zeng planned to import 20 tons of Vietnamese roasted cashews,and only entrusted Zhongshen three days before arrival.Preliminary review found three hidden dangers: first,the registration number of the Vietnamese producer would expire in two weeks; second,the nutritional claim of "rich in unsaturated fatty acids" on the label lacked NRV% labeling; third,the phytosanitary certificate did not indicate the fumigation process temperature.We activated the emergency channel,contacted the Vietnamese side overnight to update registration information,redesigned the label sample,and coordinated the Vietnamese Ministry of Agriculture to issue a supplementary process description letter.After the goods arrived at the port,the customs control instruction was "focus on checking the consistency of the label and phytosanitary certificate".Thanks to sufficient pre-preparation,the goods were released on site during inspection,and it only took 48 hours from arrival to pickup,4 days earlier than the customer expected.This case confirms the value of pre-intervention -- if the same situation occurs after goods arrival,it would cause at least two weeks of demurrage and extra costs for label modification.

## V.Hidden Value of Professional Agency

Choosing Zhongshen is essentially purchasing risk hedging capability.Explicit value is reflected in faster customs clearance and clear cost breakdown; hidden value lies in continuous optimization of the compliance system.We build exclusive files for clients,record key inspection points,test data and customs inquiry records of each batch,and form a dynamic knowledge base.The *Regulations on the Implementation of the Food Safety Law* implemented in 2026 requires importers to establish an overseas supplier review system.We directly provide review templates and remote factory inspection services,and convert regulatory requirements into operable standard operating procedures.Among clients of Supervisor Zeng,for enterprises that have cooperated for more than three years,their import compliance cost has dropped by an average of 30%,and the abnormal inspection rate has dropped from the industry average of 18% to less than 4%.This value cannot be measured by a single customs declaration fee,but is reflected in the long-term accumulation of supply chain resilience and brand reputation.

| Nut Category | Main Quarantine Risk Points | New Testing Items 2026 | Zhongshen’s Response Strategy |
| --- | --- | --- | --- |
| Almond | Aflatoxin,live insects | Ethylene oxide residue | Require foreign suppliers to provide fumigation certificate |
| Cashew | Mildew,excessive cadmium | Processing aid residue | Pre-audit production process flow chart |
| Macadamia | Excessive acid value,foreign matters | Full heavy metal testing | Pre-arrival sampling and pre-inspection service |
| Mixed Nuts | Inaccurate component declaration | Allergen labeling verification | Label review and component proportion check |

- Core document list: Certificate of origin,phytosanitary certificate,health certificate,producer’s registration number in China,Chinese and English label samples,nutrition composition test report,packing list,commercial invoice,sales contract,bill of lading,customs declaration power of attorney.
- Three elements of label compliance: Ingredients listed in descending order,mandatory allergen labeling,nutritional claims must be supported by valid data.
- Handling path for abnormal inspection: Apply for retesting → Supplement supporting documents → Coordinate customs surety → Initiate return or destruction procedure.
- Cost optimization points: Select reputable overseas suppliers,arrange pre-inspection in advance,reasonably plan arrival time to avoid peak inspection periods.
