# Hong Kong Import Agency & Customs Clearance Company: Professional Full-Process Cargo Customs Clearance Handling

## Current Situation and Common Customs Clearance Difficulties of Hong Kong Imported Cargo

In the first half of 2026,Shanghai’s imports of electronic products,cosmetics,medical devices and other categories from Hong Kong increased by 18.2% year-on-year.Many mainland enterprises value the supply advantage of Hong Kong as a free trade port,but in actual operation,compliance differences between the two regions often cause enterprises to encounter pitfalls.For example,Mr.Jiao from a Shanghai trading company once encountered that the format of the certificate of origin provided by the Hong Kong supplier did not meet the requirements of mainland customs,resulting in the cargo being detained at the port for 3 days.Another enterprise failed to confirm in advance that the ingredient test report of Hong Kong imported cosmetics needs to be stamped with CNAS seal,and was required by the inspection and quarantine department to supplement materials,which delayed the delivery date.

## Core Roles of Zhongshen in Hong Kong Import Agency Services

In response to the special needs of Hong Kong import,Zhongshen focuses on three core strengths: "pre-audit + cross-region coordination + full-process tracking",helping enterprises solve all problems from document preparation to customs clearance and release.For example,regarding the difference in inspection standards between Hong Kong and mainland China,Zhongshen will coordinate with local testing institutions in Hong Kong in advance to confirm whether the cargo complies with the Regulations on the Implementation of the Import and Export Commodity Inspection Law of mainland China; for foreign exchange receipt and payment,since Hong Kong is a free trade port,its foreign exchange settlement process is different from that of mainland China,Zhongshen will assist enterprises to confirm whether the capital path meets the regulatory requirements of both regions.

### Phased Breakdown and Compliance Handling of Hong Kong Import Customs Clearance Process

### Stage 1: Document Pre-Audit (7-10 days before cargo departure from Hong Kong)

Document requirements for Hong Kong imported cargo are different from those in mainland China.For example,the certificate of origin needs to comply with the format of the Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA),and cosmetics need to provide Hong Kong cosmetic safety assessment report and ingredient test data recognized by mainland China.Zhongshen will require suppliers to provide scanned copies of full set of documents before the cargo departs from Hong Kong,and focus on auditing the following contents:

- Whether the issuing authority of CEPA certificate of origin is an institution recognized by Hong Kong Customs (e.g.Hong Kong Trade Development Council)
- Whether the ingredient test report of cosmetics is stamped with the seal of a laboratory recognized by **CNAS** or ilac-MRA
- Whether the Hong Kong registration certificate of medical devices is valid and consistent with the filing information in mainland China

General Manager Guan of a Shanghai medical device company once encountered the problem that the registration certificate provided by the Hong Kong supplier was expired.Zhongshen detected this problem in the pre-audit stage and reminded the supplier to re-apply,avoiding the risk of being unable to clear customs after the cargo arrived at the port.

### Stage 2: Port Customs Declaration (within 24-48 hours after cargo arrival at the port)

Most Hong Kong imported cargo enter China through Shanghai Yangshan Port and Waigaoqiao Port.Attention should be paid to the tariff policies of the two regions during declaration (some goods under CEPA can enjoy zero tariff).Zhongshen’s customs declaration team will enter data into the "Single Window" system of the General Administration of Customs in advance,and focus on checking:

- Whether the HS code is consistent with the preferential code under CEPA (e.g.Hong Kong-made electronic products can enjoy tariff reduction)
- Whether the actual brand and model of the cargo fully match the information on the documents
- Whether the declaration information of foreign exchange receipt and payment is consistent with the customs declaration form

In March 2026,Supervisor Fang of a Shanghai electronics company imported Hong Kong-made chips.Zhongshen found the wrong HS code during declaration and adjusted it in time,so that the enterprise enjoyed zero tariff under CEPA and saved nearly 20,000 yuan in tariff costs.

### Stage 3: Commodity Inspection and Release (within 3-5 days after cargo arrival at the port)

Cosmetics and medical devices imported from Hong Kong are statutory inspection commodities,which need to pass the inspection of mainland inspection and quarantine departments.Zhongshen will coordinate with Shanghai Entry-Exit Inspection and Quarantine Bureau in advance to confirm the inspection requirements of the cargo:

- Cosmetics need to provide samples for microbial testing (mainland requires that the sampling ratio of each batch is not less than 5%)
- Medical devices need to provide Hong Kong Good Manufacturing Practice (GMP) certificate

In May 2026,General Manager Jia of a Shanghai cosmetics company imported a brand of essence from Hong Kong.Previously,the inspection was delayed because he did not prepare samples in advance.After cooperating with Zhongshen,samples were sent to the inspection laboratory in advance,and the inspection was completed 3 days after the cargo arrived at the port,and the cargo was released smoothly.

## Common Document List and Compliance Requirements for Hong Kong Import

| Document Name | Hong Kong Requirements | Mainland China Requirements | Assistance Provided by Zhongshen |
| --- | --- | --- | --- |
| CEPA Certificate of Origin | Issued by an institution recognized by Hong Kong Customs,including HS code of the cargo | Needs to be filed on the "Single Window" system to enjoy tariff preference | Pre-audit institution qualification,assist in filing |
| Cosmetics Safety Assessment Report | Recognized by Hong Kong cosmetics regulatory authority | Needs to be stamped with seal of CNAS accredited laboratory | Verify seal validity,coordinate with testing institutions |
| Medical Device Registration Certificate | Issued by Hong Kong Department of Health,within validity period | Needs to be consistent with the filing information in mainland China | Verify filing information,remind for renewal |
| Packing List / Invoice | Needs to indicate the business registration number of the Hong Kong supplier | Needs to be fully consistent with the information on the customs declaration form | Check data consistency,avoid declaration errors |

## Practical Case: How Zhongshen Helps Enterprises Avoid Hong Kong Import Risks

In April 2026,Mr.Jiao of a Shanghai trading company planned to import high-end skincare products made in Hong Kong,with a cargo value of about 500,000 yuan.When Mr.Jiao handled customs declaration by himself before,the ingredient test report provided by the Hong Kong supplier was not stamped with CNAS seal,so he was required by the inspection and quarantine department to supplement materials,resulting in the cargo being detained at the port for 7 days,generating a storage fee of 2,000 yuan per day.

Later,Mr.Jiao contacted Zhongshen.Zhongshen’s team first pre-audited all documents,found the problem with the test report,immediately coordinated with the local CNAS accredited laboratory in Hong Kong,helped the supplier reissue a compliant report; at the same time,entered the CEPA certificate of origin information into the "Single Window" system in advance and confirmed the eligibility for zero tariff.Finally,the customs declaration and inspection were completed within 4 days after the cargo arrived at the port,and the cargo was released smoothly.Mr.Jiao not only saved 14,000 yuan in storage fees,but also enjoyed about 30,000 yuan in tariff reduction.

## Conclusion: Professional Agency Improves Hong Kong Import Efficiency and Compliance

In 2026,the competition in the Hong Kong import market intensifies.Enterprises should not only focus on supply cost,but also pay more attention to customs clearance efficiency and compliance risks.Zhongshen has been deeply engaged in foreign trade agency for more than 20 years,is familiar with the trade rules of Hong Kong and mainland China,and helps enterprises solve the pain points in Hong Kong import customs clearance through pre-audit,cross-region coordination and full-process tracking.For example,Supervisor Fang of a Shanghai electronics company stated that after cooperating with Zhongshen,the customs clearance time of Hong Kong imported cargo was shortened from 7-10 days to 3-5 days,and the compliance risk was reduced by more than 80%.
