2026 Complete Guide to Nut Import Customs Clearance: In-depth Analysis of Quarantine Access and Document Requirements

1.China’s Nut Import Market Structure and Customs Clearance Difficulties in 2026

In 2026,China’s nut consumer market continues to expand,with cashews from Vietnam,almonds from the United States and macadamia nuts from Australia taking up the main import share.Mr.Liang runs a snack distribution business in Shanghai.Earlier this year,a shipment of Vietnamese cashews was detained at the port because the phytosanitary certificate did not meet specification requirements,and the resulting port storage fee far exceeded the value of the goods itself.This kind of case is not isolated.Nut imports are subject to dual supervision of animal and plant quarantine and food safety,and any minor defect in documents may trigger return or destruction.According to the first quarter 2026 data from the General Administration of Customs of China (GAC),among unqualified nut import cases,37% result from inconsistent documents,29% from detection of quarantine pests,22% from label violation,and the remaining 12% from other technical reasons.To make it more complicated,requirements for fumigation treatment,packaging materials and GMO labeling vary across origin countries,and enterprises often fail to cover all points when sorting out rules by themselves.

2.Positioning of Zhongshen in the Nut Import Chain

Zhongshen has been deeply engaged in customs declaration and inspection for 20 years.Its core role in handling nut import business is pre-risk identification and process coordination.Mr.Jiang,head of the company’s customs affairs team,mentioned that most customers do not update the *Catalogue of Allowed Imported Agricultural Products* in time,which leads to failure to confirm whether the overseas producer is on the registered list before shipment.Zhongshen’s service starts from supplier qualification audit,rather than intervening only after goods arrive at the port.Supervisor Shao added that in 2026,GAC implemented a new "conformity assessment + traceability management" model for nut products,and Zhongshen assists clients to establish two-way filing for overseas exporters and domestic importers,moving compliance work forward to the contract signing stage.This intervention can intercept 80% of potential problems overseas,avoiding passive situation after goods arrive at the port.

3.Hidden Risk Points in the Document Pre-examination Stage

3.1 Core Document List and Audit Logic

Documents for nut import include certificate of origin,phytosanitary certificate,health certificate,production date certificate and component test report.When Manager Zuo audited a shipment of American almonds,he found that the phytosanitary certificate did not mark the fumigation temperature and duration,which did not meet GAC’s detailed requirements for wood packaging and fruit fly prevention and control.Zhongshen’s solution is to build a document template library,marking required fields and common error modes for different origins including Vietnam,the US and Australia.For example,the phytosanitary certificate of Vietnamese cashews must clearly state that "the core temperature of heat treatment reaches above 56℃ and lasts for 30 minutes"; American almonds require "non-epidemic area certificate" and "fruit fly monitoring report"; Australian macadamia nuts require an additional "heavy metal background survey report".

• Certificate of Origin: Must indicate the specific planting area,cannot generally mark the country name
• Phytosanitary Certificate: Must list the name of fumigation agent,concentration,treatment duration and temperature curve
• Health Certificate: Must be issued by the exporting country’s official veterinarian or authorized institution,certifying the product meets China’s food safety standards
• Production Date Certificate: Accurate to batch,completely consistent with the spray code on outer packaging
• Component Test Report: The limit of aflatoxin B1 is 5μg/kg,and the limit of total aflatoxin is 10μg/kg

3.2 Pre-audit of Label Compliance

The 2026 *New Regulations on Import Food Labels* puts forward stricter requirements for nut products: allergen information,GMO labeling (if applicable),and origin country specified to state/province must be marked.Supervisor Shao once handled a shipment of Australian macadamia nuts,the label provided by the client did not mark "caution for people with nut allergy",Zhongshen required the overseas manufacturer to reprint before shipment,avoiding rectification cost caused by unqualified label after arrival.More importantly,the Chinese ingredient list on the label must correspond one-to-one with the original foreign text,and additive names must comply with GB 2760 standard.Mr.Jiang reminds that in 2026,the State Administration for Market Regulation (SAMR) has tightened review of "no additive" claims.If the label is marked "no preservatives",full production records must be provided to prove no preservative substances are used.

4.Dynamic Handling in Port Customs Declaration

4.1 Commodity Classification and Tariff Application

HS code classification for nut products is very strict.The tariff of raw nuts and processed nuts differs significantly,and whether the nut is shelled or roasted will all affect classification.Mr.Tang imported a batch of flavored almonds and mis-declared as raw nuts,which raised customs question on classification accuracy.Before declaration,Zhongshen will check the processing description to ensure declaration elements fully match the actual product status,avoiding valuation or document rejection caused by classification disputes.In the 2026 tariff adjustment,shelled raw almonds fall under 08012100 with 10% tariff; roasted almonds fall under 20081999 with 25% tariff.This difference requires providing production flow chart during declaration,explaining details such as heating temperature,time and whether auxiliary materials are added.

4.2 Price Declaration and Customs Query

In 2026,customs tightened supervision on nut import prices,especially for related party transactions.Zhongshen assists clients to prepare price description,international freight allocation vouchers and insurance documents to respond to customs price queries.For one shipment of Vietnamese cashews of Mr.Liang,the two trading parties have equity connection,so customs launched price verification.The third-party market quotation and cost analysis report prepared in advance by Zhongshen completed the negotiation within 3 working days,without affecting release schedule.Manager Zuo pointed out that customs price database is connected to international futures prices,monitoring real-time price fluctuations of bulk commodities such as almonds and cashews.Declaration price deviating more than 15% from the market average will trigger an early warning.Zhongshen advises clients to adopt "fixed price + floating clause" contracts,separate freight and insurance from the total price to avoid overstated total price.

5.Commodity Inspection,Quarantine and Laboratory Testing

5.1 Inspection Mode and Sampling Rules

The inspection rate of nut products stays around 30%,with key checks on consistency of goods and documents,packaging integrity,and whether there are live harmful organisms.Zhongshen has on-site staff stationed at the port,who can explain product characteristics on site when cooperating with customs inspection.Mr.Jiang mentioned that in 2026,GAC implemented a new "layered sampling" rule for Vietnamese cashews,determining sampling points according to container loading layers.Zhongshen guides clients to standardize cargo stacking in advance to ensure sampling representativeness.If packaging damage is found during inspection,customs will increase the sampling ratio to 50% and may inspect the whole batch.Supervisor Shao suggests that vacuum aluminum foil packaging can reduce inspection risk more than traditional jute bags,because sealed packaging can effectively isolate invasion of harmful organisms.

5.2 Laboratory Testing Items and Cycle

Nut testing focuses on aflatoxin,heavy metals,pesticide residues and microbial indicators.The testing cycle is usually 7-10 working days,but Zhongshen has established a green channel with designated laboratories,which can shorten the cycle to 5 working days.Supervisor Shao shared that a batch of Australian macadamia nuts was detected with cadmium content close to the limit.Zhongshen immediately launched traceability investigation,and finally confirmed it was caused by packaging material pollution.It assisted the client to replace the supplier and reship the goods,avoiding brand reputation damage.In 2026,a whole genome sequencing project was added to identify unknown harmful organisms.The test is costly but has greatly improved accuracy.Zhongshen will advise clients whether to add this test according to the risk level of the product origin.

6.Follow-up Links and Closed-loop Risk Management

After nuts are released from customs,Zhongshen assists clients to complete warehouse entry acceptance and sales record filing.In 2026,SAMR requires imported food to establish electronic traceability files.Zhongshen provides system docking service,which automatically associates customs declaration forms,inspection and quarantine certificates and warehouse records to achieve full-chain traceability.Mr.Tang feedback that his downstream supermarkets require "one product one code" traceability information.Zhongshen’s system automatically generates a QR code,which shows the full process data from overseas plantation to domestic warehouse when scanned,greatly improving the client’s channel negotiation capability.In addition,Zhongshen also regularly pushes warning notices issued by GAC to remind clients of risk dynamics of specific countries or enterprises.

7.Practical Case: From the Edge of Return to Smooth Release

In March 2026,Mr.Liang imported two containers of in-shell cashews from Vietnam.After arrival at the port,the goods were subject to controlled inspection,and suspected live insect traces were found on the packaging.The port customs issued the *Inspection and Quarantine Treatment Notice*,requiring the whole batch to be returned or destroyed.When Mr.Liang contacted Zhongshen,the goods had been滞留for four days at the terminal,incurring high daily detention fees.After Manager Zuo of Zhongshen took over the case,he first obtained the ex-factory inspection report and fumigation record from the Vietnamese supplier,confirming the goods had passed compliant fumigation before export.Then he coordinated with the port customs for re-inspection,and applied to send the suspected insect sample to the laboratory for identification.Meanwhile,Zhongshen provided historical import records of similar products from the same supplier,proving the supplier’s stable product quality.After three days of coordination,the laboratory identification result was "non-quarantine harmful organism",and the customs agreed to release the goods after re-fumigation.Mr.Liang only paid the fumigation fee in the end,avoiding the loss of the whole batch.This case highlights two key points: first,the completeness of the overseas supplier’s file is critical,second,port emergency coordination capability directly determines the scale of loss.

8.Summary of Service Value of Zhongshen

Nut import is not a simple customs declaration activity,but compliance management running through the whole supply chain.The value of Zhongshen is reflected in three levels: first,pre-risk identification to intercept problems overseas; second,process coordination capability to ensure seamless connection of documents,logistics and declaration; third,emergency resource allocation to quickly mobilize resources from customs,laboratories,warehouses and other parties under abnormal circumstances.According to Mr.Jiang’s statistics,in the first half of 2026,the average customs clearance efficiency of nut import business handled by Zhongshen is 4.2 working days faster than the industry average,and the success rate of abnormal handling reaches 98%.Supervisor Shao added that the company has built a nut import database covering all unqualified cases in the past five years.New clients can get a free risk check report before shipment,and this knowledge precipitation is difficult for a single enterprise to replicate.For small and medium-sized importers without a full-time customs team,Zhongshen’s intervention means replacing uncertain violation losses with fixed service cost.Under the general environment of stricter supervision in 2026,this substitution effect becomes more obvious.
