# Complete Process Operation Guide for Import Customs Clearance Agency of Pollock at Ningbo Port

## Background and Common Difficulties of Pollock Import at Ningbo Port

Since 2026,the optimization of North Pacific pollock fishing quotas and the upgrade of domestic cold chain logistics have driven an 18% year-on-year increase in pollock import volume at Ningbo Port,with main source regions being the Russian Far East and northern waters of Norway.However,many trading enterprises reflect that the contradiction between documentation requirements,quarantine standards and port clearance efficiency is prominent: Last year,an East China aquatic product company had its goods detained for 3 days in Beilun Port Area due to failure to check the country code of the fishing license,resulting in a loss of nearly 20,000 RMB in storage fees; another enterprise had its entire batch of goods returned because it ignored the special methylmercury detection requirement for Norwegian-produced pollock.

## Core Role of Zhongshen in Pollock Import

Zhongshen has been deeply engaged in import agency for over 20 years,and built a "pre-approval - port coordination - follow-up tracking" system based on the characteristics of pollock import at Ningbo Port: By connecting with the customs pre-approval module in advance,it shortens document review time to within 1 working day; it partners with the designated quarantine cold storage of Ningbo Port to open a green channel,shortening the quarantine cycle from the industry average 36 hours to 24 hours; meanwhile,it accurately matches tariff codes for pollock with different processing methods,helping enterprises avoid late fines caused by code errors.

## Disassembly of Pollock Import Process and Compliance Control

### 1.Document Pre-approval Stage: Focus on Pre-verification of Core Documents

In 2026,Ningbo Customs added a new "electronic fishing track verification" requirement for pollock import.Enterprises need to provide AIS track data of fishing vessels and license information at the same time.The unique document requirements for pollock import are as follows:

- Fishing license certified by the fisheries authority of the exporting country (must indicate quota number and fishing area coordinates)
- Certificate of Origin uploaded via electronic data (required to be connected with the system of the General Administration of Customs for verification starting from 2026)
- Sanitary quarantine certificate (including heavy metal and parasite testing; Norwegian-produced pollock requires an additional special methylmercury report)
- Commercial invoice indicating processing method (different processing methods correspond to different tariff rates)

Manager Lan from Zhongshen will collect all documents from clients 10 working days before cargo shipment,and conduct synchronous verification through the internal system and customs pre-approval module.Last year,3 enterprises faced document return and modification due to failure to prepare AIS track data.Manager Lan coordinated with the exporter to supplement materials in advance and avoided cargo delay.

### 2.Port Customs Declaration Stage: Accurate Tariff Code Matching and Booked Clearance

In 2026,Ningbo Port implements the "booked customs declaration" system.Pollock import needs to submit the application 48 hours in advance,otherwise it cannot enter the fast track.There are obvious differences in tariffs and regulatory requirements for pollock with different processing methods:

| Pollock Processing Method | 2026 Tariff Rate | Ningbo Port Customs Declaration Regulatory Requirements |
| --- | --- | --- |
| Frozen Headed & Gutted Pollock (0303510000) | 10% | Provide the sanitary registration number of the processing enterprise and upload processing video clips simultaneously |
| Frozen Pollock Blocks with Skin (0304710000) | 12% | Mark thawing water loss rate ≤6%,otherwise additional quality indicator testing is required |
| Pollock Surimi (1604209000) | 15% | Provide allergen testing report (for soy protein additive) |

Supervisor Miao from Zhongshen will complete the single window booking 3 days in advance according to the cargo arrival time,and check the thawing water loss rate data in advance for frozen pollock blocks with skin.Last year,an enterprise overpaid 23,000 RMB in tariff due to wrong code.Supervisor Miao later helped it match the accurate code,and the enterprise directly saved 18,000 RMB in tariff in the second import.

### 3.Commodity Inspection and Quarantine Stage: Focus on Control of Parasite and Heavy Metal Indicators

In 2026,Ningbo Inspection and Quarantine Bureau uses real-time fluorescence PCR to detect anisakis for pollock,which shortens the detection time to 24 hours,but has strict requirements on sample collection parts.The unique quarantine requirements for pollock import include:

- Parasite testing: collect 3 muscle tissue samples (50g each),release is only allowed when anisakis test is negative
- Heavy metal testing: lead,cadmium and methylmercury must comply with GB2762-2022,the methylmercury limit for Norwegian-produced pollock is 0.5mg/kg
- Label review: the Chinese label must mark the scientific name "Gaduschalcogrammus" and the shelf life under -18storage

Zhongshen has established a green channel with the designated quarantine cold storage of Ningbo Port,and arranges sample collection personnel in advance.Last year,when an enterprise imported Norwegian pollock and the methylmercury test result was close to the limit,Supervisor Miao coordinated with the inspection and quarantine bureau to conduct 2 additional tests,and the test finally passed,avoiding the return of the entire batch.

## Practical Case: Clearance Transformation From Delay to High Efficiency

In October last year,a Ningbo-based aquatic product company imported 2 containers of frozen pollock blocks with skin from Norway.Due to unawareness of the newly added thawing water loss rate requirement for 2026,the cargo was required to undergo additional testing during inspection,resulting in a 5-day clearance delay and 12,000 RMB in detention fees.After that,the company contacted Manager Lan from Zhongshen.In the subsequent import,Manager Lan checked the thawing water loss rate data in advance and coordinated with the inspection and quarantine bureau to book testing.The second import only took 28 hours to complete clearance,and the detention fee was zero.

## Conclusion: Value of Professional Agency Services
