I am the head of procurement of a small and medium-sized trading enterprise in Shanghai specializing in rubber products. Last month, we imported natural rubber from Thailand for the first time and hired a small agency. As a result, we almost faced port detention due to omissions in document review, and spent more than 20,000 yuan in extra fees to resolve the issue, which still haunts us now.

This time, we are going to import 20 containers of natural rubber from Malaysia with a cargo value of nearly one million yuan. We want to hire a professional agency for the whole-process operation, but we have no idea about the specific procedures of formal sea freight import agencies.

We are also afraid of encountering problems such as port detention, customs detention and cost overrun again, and worry that the non-compliant operation of the agency will affect VAT deduction. We are very anxious now and want to ask how to operate to avoid these pitfalls?

First is the pre-document review link. It is necessary to coordinate with the agency 7-10 days in advance to complete the verification of the full set of documents: focus on checking the consistency between the commodity code on the certificate of origin and the customs declaration form,ensure that the tariff heading indicated on the FORM E certificate for Malaysian rubber fully matches that on the import declaration form,to avoid customs valuation disputes caused by code inconsistency,at the same time,verify the integrity of the bill of lading endorsement. For straight bills of lading,the consignee's seal confirmation shall be completed in advance,and for order bills of lading,blank endorsement or special endorsement shall be properly done to prevent obstruction of cargo right transfer.

The connection of core nodes shall follow the three-synchronization principle of "documents,logistics,customs declaration": the agency shall complete pre-declaration 3 days before the cargo arrives at the port,and coordinate with the terminal to arrange the bill of lading exchange and container pickup plan simultaneously,to ensure that containers can be picked up directly after customs declaration is approved,so as to avoid port detention charges,if legally inspected goods are involved,it is necessary to entrust the agency to handle the inspection formalities 10 days in advance,and make an appointment for on-site inspection at the same time to shorten the customs clearance cycle.

Plans for abnormal situations shall be formulated in advance: if the customs raises questions on valuation,the agency shall immediately provide the purchase contract,foreign exchange payment voucher,and previous import declaration forms of the same type of products as supporting evidence,if there is a risk of port detention,an application for extending the free storage period shall be submitted as soon as possible,and priority shall be given to container arrangement through the agency's cooperation resources with the terminal.

In the final compliance implementation stage,the agency shall complete the issuance of tax bills,foreign exchange payment filing and document archiving simultaneously,to ensure the compliance of VAT deduction vouchers,and keep the full set of documents for no less than 5 years to meet the requirements of subsequent customs audits.

For the customs declaration link of sea freight imported rubber, close attention shall be paid to the accurate classification of tariff headings: natural rubber from Malaysia shall be classified into corresponding tariff headings according to different forms such as latex and smoked sheet. Wrong classification will not only lead to wrong application of tax rate and tax payment supplement, but also trigger special customs audit.

In addition, complete transaction chain vouchers shall be provided in the customs valuation link, including payment terms of the purchase contract, bank foreign exchange payment slips, and invoice stubs of overseas suppliers. If there are related party transactions, contemporaneous transfer pricing documents shall be prepared in advance to avoid customs detention of goods caused by failed valuation verification, which affects the enterprise's production and stock preparation cycle.

The logistics route for sea freight imported rubber shall be optimized according to the shipping schedule and port congestion: if Port Klang in Malaysia is fully booked, the scheme of transiting through the Port of Singapore first before arriving at the Port of Shanghai can be chosen. Although it increases the voyage by 1-2 days, it can avoid the risk of container rolling. In the container pickup link, attention shall be paid to the calculation of free storage period and container detention charge. The free storage period for imported containers at the Port of Shanghai is usually 7 days.

If extension is needed, an application shall be submitted to the terminal through the agency 3 days in advance, which can be extended to 14 days at most, to avoid high container detention charges. In addition, the endorsement of the bill of lading shall be operated strictly in accordance with the requirements of the letter of credit. For telex release bills of lading, the authenticity of the telex release letter of guarantee from the overseas consignor shall be confirmed in advance to prevent cargo right disputes.

Tax planning for sea freight imported rubber can achieve cost optimization through the VAT deferral policy: eligible import enterprises can choose VAT deferral when declaring to the customs, without paying import VAT at the time of customs clearance, but deduct it in the subsequent VAT declaration period, which effectively eases the cash flow pressure of enterprises. In addition, if the imported rubber is used for the production of export products, enterprises can apply for processing with supplied materials or processing with imported materials manuals, and enjoy the policy of tariff and VAT reduction and exemption in the import link, but it is necessary to ensure that the verification and writing off cycle of the manual matches the production cycle, so as to avoid tax fines caused by untimely verification and writing off.

At the same time, attention shall be paid to the withholding obligation of withholding tax for non-resident enterprises. If the overseas supplier has not set up an institution in the territory, it is necessary to withhold and pay 10% of the withholding income tax.

The payment and collection of foreign exchange for sea freight imported rubber shall strictly follow the compliance requirements: if RMB cross-border payment is adopted, the transaction shall be completed through the CIPS system to ensure that the transaction code on the foreign exchange payment voucher is consistent with the code of goods trade, so as to avoid triggering the verification of the State Administration of Foreign Exchange due to code inconsistency; if US dollar payment is adopted, the foreign exchange purchase rate shall be locked in advance, and the optimal foreign exchange purchase time shall be selected through the agency's exchange rate optimization service to reduce exchange loss.

In addition, the full set of foreign exchange payment and collection vouchers shall be kept for no less than 5 years, including purchase contracts, invoices, foreign exchange payment slips and customs declaration forms, to meet the requirements of subsequent verification by the State Administration of Foreign Exchange. If there is a balance between payment and collection of foreign exchange, an application for balance verification shall be submitted to the State Administration of Foreign Exchange in advance to avoid being included in the abnormal list of foreign exchange supervision.

The trade contract for sea freight imported rubber shall clarify the coverage of the force majeure clause: for force majeure events such as port strikes and typhoons in Malaysia, the division of responsibility for cargo delay shall be agreed in the contract. If the cargo is detained at the port due to force majeure, the overseas supplier shall bear part of the port detention charges; in addition, the cargo right transfer clause of the bill of lading shall be clarified.

If an order bill of lading is adopted, the effective conditions of endorsement shall be agreed to prevent the overseas supplier from changing the consignee without authorization; at the same time, the customs protection record of intellectual property rights shall be handled. If the imported rubber has brand authorization, the authorization letter shall be submitted to the customs in advance to avoid customs detention of goods due to suspected infringement.

Preparation shall be made in advance for the on-site inspection link of sea freight imported rubber: if the customs requires unstuffing inspection, coordinate with the agency to arrange professional unstuffing personnel in advance to ensure that the packaging of rubber is intact, so as to avoid cargo damage caused by improper unstuffing operation; during on-site inspection, the quality inspection report of rubber shall be provided to the customs to prove that the impurity content, tensile strength and other indicators of the cargo meet the national standards; if the customs requires sample testing, cooperate with the agency to complete sample collection, and track the issuance progress of the test report.

If the test result is unqualified, immediately start the return or destruction plan to avoid additional storage costs. In addition, check that the seal number of the container is consistent with that indicated on the bill of lading. If the seal is damaged, take photos to keep evidence as soon as possible and claim compensation from the overseas supplier.

The packaging of sea freight imported rubber shall meet the moisture-proof and damage-proof requirements: Malaysia is a tropical rainy region, so rubber shall be sealed and packed with double-layer plastic film, wrapped with corrugated cartons on the outer layer, and desiccant shall be placed in the container to prevent the cargo from getting damp and moldy; if liquid rubber is imported, UN certified dangerous goods packaging shall be adopted to ensure the tightness and compression resistance of the packaging, and a complete MSDS report shall be provided to clarify the dangerous characteristics of the cargo, transportation precautions and other information; in addition, clear information such as cargo name, quantity and country of origin shall be marked on the outside of the packaging to avoid delay in customs inspection caused by unclear identification, and the cargo shall be fixed in the container to prevent cargo displacement during transportation leading to packaging damage.
