# AC Foaming Agent Export to Vietnam Agency, Full Process Solution

## 2026 Market Background and Core Challenges of Exporting AC Foaming Agent to Vietnam

In 2026,the Vietnamese government continues to promote the "Manufacturing Upgrading Plan".The demand for AC foaming agent from three major industries: building materials,new energy vehicle interiors,and packaging materials,has increased by 12.7% year-on-year.Among them,driven by over 8 million new residential projects in Vietnam,the demand for low-toxicity AC foaming agent in the green building material sector accounts for 62% of the total.However,many Chinese domestic manufacturers report that they often encounter obstacles due to insufficient policy adaptation when exporting to Vietnam:

- Vietnam’s 2025 updated "Regulations on the Administration of Chemical Imports" requires that importers must hold a "Hazardous Chemical Business License",and the scope of the license must accurately match the hazard classification of AC foaming agent (some products are Class 2.1 flammable gases).Over 30% of manufacturers have their goods detained by customs due to non-compliant importer qualifications;
- Vietnamese Customs strictly inspects the HS code (39129000) of AC foaming agent.If environmental parameters such as "phthalate-free" are not marked in the declaration,the goods will be required to be reclassified,causing a delay of more than 7 days;
- The export tax refund process requires synchronization of the "import declaration filing number" of the Vietnamese importer,but most manufacturers cannot obtain it in time due to information asymmetry,resulting in a delay of more than 10 working days for tax refund arrival.

## Core Value of Zhongshen’s Export Agency Services for the Vietnamese Market

As a Shanghai-based agency enterprise with 20 years of deep experience in foreign trade,Zhongshen has built a service system of "policy preliminary research + local liaison + full-process control" targeting the core pain points of exporting AC foaming agent to Vietnam.On one hand,the team updates policy developments from the Ministry of Industry and Trade of Vietnam and General Administration of Customs of Vietnam every month (such as the tariff reduction rules for low-toxicity AC foaming agent issued by Vietnam in March 2026); on the other hand,Zhongshen has set up a local liaison office in Ho Chi Minh City to directly handle importer qualification review and customs clearance coordination.A manufacturer of foaming agent based in East China (General Manager Ma) who cooperated with us last year reported that after using Zhongshen’s agency service,the overall cost of exporting to Vietnam decreased by 8.2%,and customs clearance efficiency increased by 40%.

## Decomposition of Service Modules and Risk Response for Exporting AC Foaming Agent to Vietnam

### 1.Document Preparation: Unique Vietnamese Certification Requirements and Countermeasures

Vietnamese Customs’ requirements for "localization adaptation" of export documents for AC foaming agent are much stricter than other Southeast Asian countries,with core pain points concentrated in three certifications:

- The certificate of origin must be certified by the China Council for the Promotion of International Trade and affixed with an anti-counterfeiting QR code recognized by Vietnamese Customs,and must be marked with a special note "Exported to Vietnam";
- Commercial invoices and packing lists must be provided with Vietnamese translations,and the translation company must be registered with the Ministry of Industry and Trade of Vietnam (the registration number can be queried via the official website of Vietnamese Customs);
- The Safety Data Sheet (SDS) for chemicals must comply with Article 12 of Vietnam’s Law on Chemical Safety Management,include 18 supplementary items such as "local Vietnamese emergency contact information" and "HS code corresponding description",and must be stamped and confirmed by a local Vietnamese third-party institution.

Zhongshen’s solution is as follows: the document team is equipped with 3 Vietnamese translators,and has long-term cooperation with 3 translation companies registered with the Ministry of Industry and Trade of Vietnam to ensure 100% compliance of translations; all documents are pre-audited 3 working days in advance,with focus on checking the matching between HS code (39129000) and product ingredients,to avoid application rejection due to "inconsistency between ingredients and declaration".

### 2.Customs Clearance Service: Key Inspection Points of Vietnamese Customs and Efficiency Improvement

Vietnamese Customs’ inspection for AC foaming agent customs clearance focuses on "hazardous chemical compliance" and "importer qualification".Zhongshen breaks through barriers via the "local agency + pre-communication" mechanism,the specific comparison is as follows:

| Common Problems in Vietnamese Customs Clearance | Zhongshen’s Solution | Result |
| --- | --- | --- |
| Hazard classification identification report does not comply with Vietnamese CNAS standards | Cooperate with 3 local CNAS-accredited institutions in Vietnam to complete identification report audit in advance | Avoid being required to re-identify during customs clearance,saving 5-7 days |
| Importer license validity not confirmed in advance | Pre-audit of importer qualification is included in the agency service,with a reminder for update 7 days before expiration | Eliminate cargo detention caused by qualification issues |
| Vietnamese warning labels on cargo are non-compliant | Provide label design templates,printed only after review by Vietnamese specialists | Labels pass customs inspection at the first attempt,no additional rectification costs |

### 3.Tax Refund Service: Impact of Vietnamese Importer Filing on Tax Refund

China’s 2026 export tax refund policy requires that tax refund for AC foaming agent must provide the "Vietnamese import declaration filing number" issued by Vietnamese Customs.If the importer fails to complete the filing within 3 days after the cargo arrives at the port,it will cause mismatch between the Chinese customs declaration data and Vietnamese import data,leading to rejection of the tax refund application.

- Zhongshen’s foreign exchange payment and collection specialist will confirm the payment route of the Vietnamese importer in advance (priority is given to routes where the Vietnamese bank’s SWIFT code is filed with the State Administration of Foreign Exchange of China),to ensure the consistency between the foreign exchange collection certificate and the declaration information;
- Liaise with the local Vietnamese liaison office to track the progress of the importer’s import declaration filing,and synchronize feedback to the Chinese tax refund specialist;
- Establish a "pre-audit checklist for tax refund" to confirm all documents are complete before cargo export,avoiding delays caused by supplementary documents later.

### 4.International Transportation: Hazardous Cargo Storage Requirements at Vietnamese Ports

Storage requirements for Class 2.1 hazardous cargo (part of AC foaming agent) at Ho Chi Minh Port and Hai Phong Port of Vietnam: Special warehouses must hold a "hazardous cargo storage license" issued by the Vietnam Maritime Administration,and each batch of cargo must be stored separately to avoid mixing with other hazardous cargo.

All local Vietnamese logistics providers cooperating with Zhongshen hold the qualification issued by the Maritime Administration,and lock special warehousing space 7 days in advance; before transportation,containers are affixed with Vietnamese hazardous cargo marks that comply with ISO 17363 standard,and a hazardous cargo transportation specialist is assigned to track the whole journey.Last year,a 20-ton shipment of Class 2.1 AC foaming agent exported by a manufacturer only took 8 days from Shanghai Port to Ho Chi Minh Port,with no storage delays at all.

## How Zhongshen Improves Customs Clearance and Tax Refund Efficiency

A manufacturer of foaming agent based in South China (Ms.Feng) who cooperated with us last year reported that when she exported to Vietnam on her own before,customs clearance was delayed for 11 days because the Vietnamese emergency contact number was not marked on the SDS,resulting in port detention fees exceeding 3200 RMB.After choosing Zhongshen’s agency service this year,via the "pre-audit + local liaison" mechanism,the customs clearance cycle was reduced to 2.5 days,tax refund arrival was 6 working days earlier than before,and 2900 RMB of port detention fees was saved.

The core of Zhongshen’s efficiency improvement is "process pre-positioning": we establish an "exclusive service group for the Vietnamese market" consisting of 4 specialists for documents,customs clearance,tax refund and transportation,who synchronize cargo progress in real time; we have established a pre-communication channel with Vietnamese Customs,respond in advance to the "tariff reduction for low-toxicity AC foaming agent" policy updated in May 2026,and helped 3 manufacturers enjoy a 3% tariff preference.

## Customized Services: Matching the Export Needs of Different Manufacturers

Zhongshen’s service team (Supervisor Shen) will develop a customized solution according to the manufacturer’s product specifications,export volume and target port:

- Small traders can choose the basic "document + customs clearance" agency service,with fees settled per batch;
- Large manufacturing enterprises can choose "full-process agency + foreign exchange payment and collection + tax refund custody",and enjoy monthly settlement discounts and a dedicated account manager;
- For manufacturers exporting low-toxicity AC foaming agent,we additionally provide "Vietnam environmental certification consulting" service,helping connect with the recommendation channel of the Vietnam Green Building Materials Association.

In 2026,the market demand for AC foaming agent in Vietnam continues to grow,but policy barriers are also constantly updating.From minor adjustments to HS codes to substance restrictions,every change may affect export efficiency.Choosing a professional export agency can not only reduce compliance risks,but also save time and costs.If you have demand for exporting AC foaming agent to Vietnam,you are welcome to contact Zhongshen’s service team to customize a suitable agency solution for you.
