# How to Choose an Export Agency? 3 Core Judgment Criteria

## I.Market Status and Common Challenges of Smartphone Accessories Export to Vietnam

In 2026,the market size of Vietnam’s smartphone accessories will exceed USD 1.2 billion,with Chinese accessories accounting for more than 60%.However,with Vietnam’s upgraded compliance requirements for imported goods,many exporters have encountered new problems: some enterprises have their goods detained due to incorrect filling of RCEP Certificate of Origin,some overpay 3% of tariffs due to lack of understanding of Vietnam’s latest tariff schedule,and some have their tax refund cycle extended to more than 45 days due to non-standard document procedures.

## II.Core Value of Zhongshen’s Export Services for Vietnam

Zhongshen has focused on the Vietnamese market for more than 20 years.In response to the above pain points,we provide customized agency services for clients centering on two core directions: "compliance pre-check + efficiency optimization".For example,last year we helped a Shanghai-based accessories manufacturer deal with Vietnam customs clearance delay,and completed document revision in only 3 days,helping the client avoid storage demurrage of RMB 12,000 per day.

## III.Service Module Breakdown: Targeted Response to Vietnam’s Policies

### 1.Document Service: Precise Control of RCEP Certificate of Origin

As an RCEP member,Vietnam will reduce the preferential tariff on Chinese smartphone accessories from 8% to 5% in 2026,but requires the Certificate of Origin to include 3 key information such as "regional value content" and "direct transport certificate".Many enterprises have their declarations returned by Vietnam Customs due to missing the "direct transport certificate".

Zhongshen’s response solutions:

- Pre-audit all documents 3 days in advance,especially the 3 key information on the RCEP Certificate of Origin;
- Cooperate with local Vietnam customs clearance team to synchronize the latest customs requirements in real time;
- Last year,a client’s declaration was returned due to document error,and Manager Ji from Zhongshen coordinated the supplement and correction on the same day,avoiding cargo detention at the port.

### 2.Customs Clearance Service: "Compliance First" Response for Vietnam Customs

In 2026,Vietnam Customs will strengthen random inspection on "under-declaration of value" and "incorrect commodity coding",with the inspection rate rising from 15% last year to 22%.If under-declaration is confirmed,the enterprise will face cargo detention plus a fine of 5% of the cargo value.

Zhongshen’s response solutions:

| Vietnam Customs Risk Points | Zhongshen’s Response Measures | Client Benefits |
| --- | --- | --- |
| Incorrect commodity coding (e.g.accessories mislabeled as finished products) | Establish Vietnam Customs tariff schedule database,and check the coding 1 week in advance | Commodity coding error rate reduced from 12% to less than 0.5% |
| Random inspection of under-declared value | Provide 3 Vietnam import declaration forms of similar commodities for reference | Inspection pass rate increased to 92% |
| Port demurrage (USD 150 per container per day) | Make reservation with Vietnam port yard in advance,and pick up goods within 24 hours after customs clearance | Average port detention time reduced from 5 days to 1.5 days |

### 3.Tax Refund Service: Policy Connection between Vietnam and China

Smartphone accessories exported from China to Vietnam that meet the requirements are eligible for export tax refund (refund rate 13%),but Vietnam requires exporters to provide "cargo customs clearance certificate" and "foreign exchange receipt voucher".Some enterprises suffer delayed tax refund due to failure to synchronize these two vouchers.

Zhongshen’s response solutions:

- Establish "document synchronization mechanism": Send the Vietnam Customs clearance certificate back to China within 24 hours after customs clearance is completed;
- Synchronize foreign exchange receipt and payment with tax refund: Generate foreign exchange memo required for tax refund declaration within 1 day after foreign exchange is received;
- Last year,a client’s original tax refund cycle was 45 days,which was shortened to 28 days through Zhongshen’s service,with capital turnover efficiency increased by 30%.

## IV.How Agency Services Improve Customs Clearance and Tax Refund Efficiency

Zhongshen’s efficiency improvement for the Vietnamese market mainly comes from three aspects:

- Local team connection: We have resident staff in Ho Chi Minh City,Vietnam,who can directly connect with the customs to avoid cross-border communication delays;
- Digital system: The self-developed document pre-audit system can automatically check 12 key information required by Vietnam Customs,shortening the pre-audit time from 2 hours to 15 minutes;
- Experience accumulation: More than 20 years of experience in handling export to Vietnam.For example,we know that Vietnam Customs has a higher inspection rate from the 15th to the 20th of each month,so we will arrange the customs clearance time in advance.

## V.Customized Services: Meet the Needs of Different Clients

Zhongshen will provide customized solutions according to the client’s product type (such as mobile phone batteries,screen protectors),export scale (such as annual export of RMB 5 million or RMB 20 million),and target port (such as Ho Chi Minh Port or Haiphong Port).For example,for clients with annual export of more than RMB 20 million,we provide "VIP customs clearance channel",which shortens the customs clearance time by another 1 day; for products requiring Vietnam COC certification such as mobile phone batteries,we assist in handling the certification 30 days in advance to avoid delays.

If your products are planned to be exported to Vietnam,you may contact Zhongshen according to your actual situation.Our team with 20 years of experience will help you solve compliance and efficiency problems and make the export process smoother.
