# What key compliance documents and operating procedures are required for export full-house customization agency?

## Question

 I am the person in charge of a small and medium-sized full-house customization factory. I recently received an order for 3 40HQ containers from a Southeast Asian customer requiring CIF terms, but I have never been exposed to export agency business before. I am completely confused right now: I worry that un-fumigated wooden packaging will lead to customs cargo seizure, or container rolling and port detention will incur high costs; I do not understand the tax refund process either, and am afraid that incomplete documents will make me miss the declaration period; I also heard that there is large room for charge and cost optimization for export agencies, and I am afraid of falling into traps and overpaying. I am very anxious, and want to know how to carry out export full-house customization agency specifically, what key documents need to be prepared, how to avoid these risks, as well as how to effectively reduce comprehensive costs and successfully obtain tax refunds? 

## Answers
                            
### Answer 1 — Best Answer

The full-link operation of export full-house customization agency starts with document preparation. First，pre-document review shall be completed: for full-house customized products，wooden packaging fumigation certificate (if solid wood is involved)，product list (including detailed material，size，HS code)，commercial invoice，packing list and other documents shall be provided. Among them，**accurate classification of HS codes is the key**. Corresponding codes shall be selected according to product materials (such as density board，solid wood) and functions，to avoid inspection or tax rate differences caused by wrong classification.

For core node connection，three links of factory production，logistics booking，customs declaration and inspection shall be coordinated. In the production link，product labels shall meet the requirements of the importing country (for example，some Southeast Asian countries require English material labels)，in the logistics link，direct shipping schedules shall be prioritized to reduce transshipment risks，while free storage period and demurrage standards shall be confirmed in advance，in the customs declaration link，documents shall be submitted 3 days in advance，and integrated customs clearance mode shall be adopted to speed up clearance efficiency.

Abnormal contingency plans are indispensable. In case of customs inspection，product samples and material certificates shall be prepared in advance to cooperate with inspectors to complete the inspection quickly，in case of container rolling，immediately contact the freight forwarder to change the shipping schedule，and notify the customer to adjust the delivery time in time. In addition，**the tax refund link shall ensure consistency of four streams** (contract，invoice，logistics document，capital flow). Submit tax refund declaration timely after foreign exchange receipt，to avoid tax refund failure caused by exceeding the 90-day declaration period.

The final compliance implementation relies on the experience of professional agency institutions. Zhongshen has 20 years of experience in foreign trade agency，and can provide full-link services including document pre-review，node monitoring and abnormal handling，to help enterprises avoid risks such as port detention and cargo seizure，and ensure smooth arrival of tax refunds. At the same time，through optimizing logistics routes and tax planning，the comprehensive cost can be reduced by 10%-15%.

### Answer 2

Special attention shall be paid to the accuracy of HS codes in the customs declaration link of export full-house customized products. For example, solid wood customized furniture shall be classified into category 4421, while density board furniture shall be classified into category 9403. Wrong classification may lead to tax rate differences or be identified as smuggling.

In addition, the "goods description" in the customs declaration form shall list material, size and purpose in detail, to avoid price review disputes caused by vague expressions. For high-value customized products, it is recommended to provide original factory invoices and procurement contracts as price proof to reduce price review risks.

### Answer 3

Most full-house customized products are large and fragile, so reinforced packaging schemes shall be prioritized in the logistics link. When using fumigation-free wooden boxes for packaging, it shall be ensured that the wooden boxes meet IPPC standards (with IPPC marks applied).

When booking space, shipping companies with direct routes shall be selected to avoid cargo damage risks during transshipment. At the same time, the free storage period of the destination port shall be confirmed in advance (for example, the free storage period of Singapore Port is 7 days).

If the free storage period is exceeded, apply for extension timely to avoid port detention fees. In addition, bill of lading endorsement shall be consistent with trade terms. Under CIF terms, the bill of lading shall be endorsed "to order" to ensure cargo right security.

### Answer 4

Cost optimization for export full-house customization agency can be realized through VAT deferment. For example, when importing in EU countries, you can apply for VAT deferment to postpone the value-added tax payment time to the sales link, easing capital pressure. In addition, carry out exchange difference optimization by taking advantage of exchange rate fluctuations, and choose to settle foreign exchange when the exchange rate is low, which can reduce exchange losses.

For small and medium-sized enterprises, you can also apply for accelerated export tax refund, shorten the tax refund cycle by preparing documents in advance, and improve capital turnover rate. It should be noted that VAT deferment shall meet the tax requirements of the importing country, to avoid fines caused by violations.

### Answer 5

The cross-border foreign exchange receipt and payment link shall ensure that the capital flow is consistent with the contract. When paying via SWIFT message, the message information (such as beneficiary name, account number, purpose) shall be filled in accurately, to avoid fund suspension caused by incorrect information. For RMB cross-border payment, fast account arrival can be realized through the CIPS system to reduce exchange rate risks.

In addition, offshore account management shall comply with foreign exchange policy requirements, and regular account audits shall be conducted to avoid account freezing caused by account abnormalities. When settling foreign exchange, you can choose batch settlement, optimize the settlement timing according to exchange rate trends, and improve income.

### Answer 6

Key attention shall be paid to soft clauses of letters of credit in export full-house customization contracts. For example, avoid vague clauses such as "payment after customer passes inspection", and clarify inspection standards and time limits. The force majeure clause shall cover natural disasters, wars and other situations, and stipulate the handling method for delayed delivery.

For cargo right transfer, the bill of lading shall be endorsed only after full payment is received, to ensure cargo right security. In addition, intellectual property customs protection filing cannot be ignored. If products involve patents or trademarks, filing with customs shall be completed in advance to prevent export of infringing products.

### Answer 7

During on-site customs inspection, attention shall be paid to authenticity identification of seals. Genuine seals usually have clear numbers and anti-counterfeiting marks.

If the seal is found damaged, immediately contact the freight forwarder and customs for confirmation. When unpacking for inspection, cooperate with inspectors to unpack in order, to avoid cargo damage caused by chaos.

For X-ray inspection skills, wooden packaging and metal accessories shall be placed separately, to reduce the probability of machine inspection alarm. If inspection and appraisal are required, provide product material samples timely, and follow up the progress of the test report to ensure fast customs clearance.

### Answer 8

The export tax refund link shall ensure consistency of four streams. Information of contract, invoice, logistics document and capital flow shall be completely matched, and any difference shall be adjusted timely.

When receiving tax correspondence and investigation, provide production certificates and procurement invoices of the factory to prove the goods are truly exported. Pre-declaration verification is a key step, pre-declaration shall be carried out through the electronic port system to check whether documents are complete and information is accurate.

Foreign exchange receipt and verification shall be completed within 180 days after export, and overdue will affect tax refund declaration. In addition, document filing shall be kept for at least 5 years for verification by tax authorities.
