Shanghai Nut Import Agency, Full-process Compliance Service from Origin to Port

Core Pain Points and Industry Background of Nut Import in Shanghai

In 2026,the nut import volume at Shanghai Port exceeded 120,000 tons,among which macadamia nuts and almonds account for over 60%,with main origins being Australia,the United States and Thailand.With the continuous upgrading of China’s quarantine standards for imported food,and unique pest and disease control requirements for different origins,self-operated import enterprises often encounter three major pain points: First,failed document audit — health certificates provided by some Southeast Asian origins do not mark aflatoxin limit,leading to customs declaration rejection; Second,quarantine cycle delay — anthracnose detection is required for Australian nuts,non-standard sampling process easily prolongs customs clearance time; Third,poor warehousing connection — nuts are sensitive to temperature and humidity,temporary port warehouses lack low-temperature conditions,easily leading to deterioration and loss.

Core Value of Zhongshen in Nut Import

As a service provider deeply engaged in Shanghai’s foreign trade agency for over 20 years,Zhongshen has established a full-link service system of "origin connection - document pre-audit - port customs clearance - warehousing and distribution" based on the characteristics of nut import.Last year,an East China snack enterprise imported Thai almonds through Zhongshen.We found the certificate of origin lacked a "fumigation certificate" through advance pre-audit,after timely correction,the customs clearance cycle was shortened by 5 days compared with self-declaration,avoiding loss caused by warehousing delay.

Full-process Disassembly and Compliance Control of Nut Import

1.Document Pre-audit: Avoid Hidden Risks of Certificate of Origin and Quarantine Certificate

In addition to conventional documents including bill of lading,invoice and packing list,core documents for nut import need to focus on Certificate of Origin (Form E/F/A etc.),Official Health Certificate,Fumigation/Heat Treatment Certificate.Special requirements for different origins are as follows:

• Australian nuts: Health certificate must clearly mark "No Anthracnose Detected",and certificate of origin must comply with China-Australia FTA rules to enjoy preferential tax rate;
• Thai almonds: Fumigation certificate (for stored pests) is required,and health certificate must include aflatoxin B1 limit (≤5μg/kg);
• American pistachios: Quarantine certificate issued by United States Department of Agriculture (USDA) is required,clearly confirming no walnut weevil carried.

Zhongshen’s service: 10 working days before shipment,we arrange dedicated staff to audit all documents,mark key points according to the above special requirements,if non-conformity is found (such as Thai almond health certificate without aflatoxin limit marking),we contact foreign suppliers for correction in time to avoid return shipment after goods arrival.

2.Port Customs Declaration: Accurately Match Tariff Rates and Declaration Elements

Declaration elements for nut import at Shanghai Port need to include "processing technology (raw/cooked)","added flavoring or not","origin" etc.Tariff rate varies greatly with different origin and processing technology:

Zhongshen’s service: Before declaration,we match the latest customs tariff database,prepare online verification materials for certificate of origin in advance for FTA preferential rate of Australian nuts; if an enterprise declares cooked salt-baked almonds,we clearly mark the processing temperature (≥120℃) to avoid tariff increase caused by vague declaration elements.

3.Commodity Inspection (CIQ): Focus on Specific Quarantine Index Testing for Nuts

Mandatory testing indicators for imported nuts by Shanghai Commodity Inspection Bureau include: aflatoxin (B1,B2,G1,G2),heavy metals (lead,arsenic),pests and diseases (such as Australian nut anthracnose,American walnut weevil).Key sampling inspection points differ by origin:

• Southeast Asian nuts (Thailand,Vietnam): Focus on aflatoxin B1 testing (limit ≤5μg/kg),direct destruction if exceeding standard;
• Australian nuts: On-site inspection for anthracnose pathogen is required,sampling ratio is 5%;
• North American nuts (United States,Canada): Testing for quarantine pests such as weevil is required.

Zhongshen’s service: We communicate sampling plan with commodity inspection department in advance,arrange dedicated staff to accompany on-site inspection,if expedited testing is required after sampling,we can coordinate with the laboratory for priority processing (for example,last year an enterprise imported Australian nuts with urgent production demand,we coordinated and shortened the testing cycle from 7 days to 3 days).

4.Warehousing and Distribution: Meet Low-temperature Storage Requirements of Nuts

Nuts have strict requirements for storage environment: temperature needs to be controlled at 15-20℃,humidity ≤60%,avoid direct sunlight.Some temporary warehouses at Shanghai Port lack low-temperature conditions,which easily leads to nut deterioration.

Zhongshen’s service: We connect with low-temperature warehousing resources in Shanghai Free Trade Zone,provide constant temperature warehouses of over 1,000 square meters,complete cargo transshipment within 24 hours after customs clearance,and use refrigerated trucks during distribution to ensure nut quality.

Practical Case: Risk Avoidance for Thai Almond Import

In October 2025,a Shanghai-based snack enterprise planned to import 3 containers of Thai almonds.When contacting the freight forwarder independently,it failed to notice that the Thai health certificate needs to mark aflatoxin limit,and the goods were rejected by commodity inspection after arrival at the port.Then the enterprise entrusted Zhongshen to handle the case:

• Step 1: Coordinate with the Thai supplier to resend a compliant health certificate (marked with aflatoxin B1 ≤5μg/kg);
• Step 2: When re-declaring,add detailed description of the fumigation certificate in documents (heat treatment temperature 56℃,duration 24 hours);
• Step 3: Coordinate with commodity inspection for expedited testing,completed aflatoxin testing within 3 days,and got smooth release.

The final customs clearance cycle was shortened from the expected 10 days to 7 days,avoided the storage fee (about 2000 RMB per day) caused by goods detention at the port,and no deterioration loss occurred.
