# Zhongshen Guides: How to Meet Qualification for LC Issuance via Import Agency?

## Southeast Asian Natural Rubber Import: LC Issuance Qualification is an Inevitable Core Threshold

Since 2026,the export volume of Southeast Asian natural rubber to China has maintained double-digit growth.As a major import port,Shanghai has a monthly rubber import volume exceeding 20,000 tons.However,many small and medium-sized trading enterprises reflect that the most troublesome part in the import process is not the source of goods,but the connection between LC issuance qualification and subsequent compliance — either insufficient bank credit cannot issue a letter of credit,or mismatched documents and quarantine requirements lead to customs clearance delays.

## Core Role of Zhongshen in LC Issuance for Natural Rubber Import

Targeting such problems,Zhongshen focuses on the whole process of LC issuance for natural rubber import,and mainly solves two pain points: first,helping enterprises make up for the deficiency of LC issuance qualification and coordinate with banks to complete credit supplement; second,customizing letter of credit clauses based on phytosanitary and packaging compliance requirements of rubber to avoid document discrepancies.In 2025,a Shanghai trading company only had 5 million yuan of bank credit,which could not meet the LC issuance demand of 12 million yuan for rubber import.With the assistance of Manager An from Zhongshen,the enterprise supplemented the long-term cooperation agreement with Thai suppliers and pre-audit materials of rubber inspection reports,successfully obtained temporary bank credit and completed LC issuance smoothly.

## Whole Process Disassembly and Compliance Control of LC Issuance for Natural Rubber Import

### 1.Pre-audit of LC Issuance Qualification: Pass the "Dual Threshold" of Bank and Quarantine First

Before issuing LC for natural rubber import,enterprises need to meet both bank credit requirements and pre-quarantine conditions.Zhongshen will conduct two rounds of pre-audit first:

- Bank side: Verify the enterprise’s foreign exchange income and expenditure records in the past 6 months and the authenticity of trade contracts (supplier qualification certificate is required).If credit is insufficient,assist in supplementing the "Pre-report of Import Commodity Inspection" as credit enhancement material;
- Quarantine side: Confirm whether the supplier is included in the "Southeast Asian Natural Rubber Quarantine Filing List" of the General Administration of Customs of China,and require a pre-provided phytosanitary certificate sample to avoid subsequent document discrepancies.

In March 2026,a Zhejiang enterprise’s supplier was not on the filing list,which was pointed out in time by Supervisor Yin from Zhongshen before LC issuance.The enterprise replaced with a filed supplier and avoided the subsequent risk of return shipment during customs clearance.

### 2.Customization of Letter of Credit Clauses: "Precise Clauses" Matching Rubber Characteristics

Letter of credit clauses for natural rubber cannot copy general templates,three core points need to be clarified,and Zhongshen will assist enterprises to confirm with banks:

| Clause Type | Unique Requirements for Natural Rubber | Key Assistance from Zhongshen |
| --- | --- | --- |
| Quality Clause | Clear rubber grade (e.g.TSR20),impurity content ≤0.05%,moisture ≤0.6%,SGS inspection report attached | Liaise with SGS to confirm inspection standards in advance,avoid inconsistency between the report and the letter of credit |
| Packing Clause | Containers require fumigation treatment,fumigation certificate shall be provided; origin,grade,gross weight/net weight shall be marked on the package | Audit the fumigation certificate sample to ensure the marked content is consistent with the letter of credit |
| Presentation Clause | Bill of lading shall indicate "rubber is not mixed with dangerous goods",phytosanitary certificate shall be issued by the official authority of the place of origin | Remind the bank to specify the interval between presentation deadline and bill of lading date in the letter of credit (no more than 21 days) |

### 3.Bank LC Issuance Liaison: Solve Credit and Quota Problems

In 2026,banks have stricter credit audits for import LC issuance,especially for commodities with large unit price fluctuations such as natural rubber.Zhongshen will assist enterprises in:

- If the enterprise has insufficient credit,provide "Import Agency Guarantee Letter" to help the enterprise apply for temporary bank quota;
- Liaise with professional rubber customer managers of the international business department of the bank,avoid clause errors caused by customer managers’ unfamiliarity with rubber characteristics;
- Confirm LC issuance fee (the average rate of Shanghai banks in 2026 is 0.12%-0.15%),help enterprises choose the bank with the optimal rate.

### 4.Document Audit and Customs Clearance Connection: Avoid "Easy LC Issuance,Difficult Customs Clearance"

After LC issuance,Zhongshen will simultaneously audit all documents submitted by suppliers,with key verification on:

**1.Phytosanitary Certificate:** Must contain the statement that "this batch of rubber does not carry quarantine pests",and the issuance date is not earlier than the shipment date;

**2.Fumigation Certificate:** Must indicate the fumigant (e.g.methyl bromide),temperature and time,and be consistent with the container number;

**3.Bill of Lading:** Must be a clean bill of lading,and the packing description is consistent with the letter of credit (e.g."20-foot container,loaded with TSR20 natural rubber,fumigated").

In May 2026,an enterprise had one missing digit in the container number on the fumigation certificate,which was found in time by General Manager Chai from Zhongshen.The supplier was required to reissue the certificate,avoiding the risk of container detention during customs clearance.

## Value of Zhongshen Agency: Efficiency Improvement and Risk Avoidance

According to the data of the first half of 2026,for natural rubber import projects agencyed by Zhongshen,the average LC issuance time is shortened from 7-10 days (self-handled by enterprises) to 3-5 days,and the customs clearance delay rate is reduced from the industry average 15% to below 3%.The core reasons are:

- Pre-audit LC issuance qualification and quarantine requirements in advance,avoid repeated material supplement;
- Customize letter of credit clauses matching rubber characteristics,reduce document discrepancies;
- Liaise with professional personnel from banks and customs to speed up the review process.

For small and medium-sized import enterprises,there is no need to invest extra human resources to learn LC issuance and quarantine compliance,you only need to focus on supply and sales,while Zhongshen is responsible for full-process qualification control and risk avoidance.
