How to Choose an Import and Export Agency in 2026? Practical Guide to Shanghai Customs Declaration and Tax Rebate

Core Capability Breakdown of Import and Export Agencies in 2026

As the global trade pattern continues to adjust in 2026,with geopolitical trade barriers and compliance requirements upgraded,enterprises shall focus on four practical capabilities when selecting import and export agencies: pre-audit of destination country certification,anti-dumping risk prediction,tax rebate process optimization,and closed-loop foreign exchange collection security.Agencies headquartered in Shanghai,relying on local customs broker resources and nationwide port linkage,can complete the full process of "declaration-inspection-release" within 48 hours,saving 3-5 days of processing time compared with non-local agencies.

I.Port of Destination Certification: From "Post-event Remedy" to "Pre-event Pre-audit"

Destination country certification is the "first line of defense" for foreign trade agencies.In 2026,Middle Eastern markets such as Saudi Arabia and the United Arab Emirates have imposed stricter requirements on SASO certification.A machinery manufacturing enterprise was required to supplement certificates after goods arrived at the port because it failed to complete the "consistency verification of energy efficiency parameters" of products in advance,resulting in more than 100,000 RMB of port demurrage charges.Zhongshitong implements a three-level pre-audit mechanism for agency services:

• Submit product test reports to the official authority of the destination country (such as the Saudi SASO laboratory) 15 working days in advance
• Verify the consistency between the "technical parameter page" in the declaration,the product nameplate and the instruction manual (for example,EU CE certification shall match EN standards)
• Provide pre-certification services from third-party testing institutions (SGS,BV) for high-risk categories (such as chemicals and medical devices)

Special attention shall be paid to the EU market: 6 new substances of very high concern (SVHC) have been added to the newly implemented REACH regulation in 2026.Agencies shall complete the update of the substance list before customs declaration to avoid customs clearance delays caused by "undeclared newly added substances".

II.Anti-Dumping Early Warning: Replace "Empirical Judgment" with "Data Model"

In 2026,the U.S.Department of Commerce launched the 12th anti-dumping sunset review investigation on Chinese photovoltaic modules.An export enterprise was levied a 18.3% provisional anti-dumping duty because it failed to receive early warning in time.Zhongshitong has established a dynamic monitoring model relying on the "Trade Compliance Early Warning System" of the General Administration of Customs:

The chemical industry shall pay special attention: India will levy anti-dumping duty on carbon black for tires from China in 2026.Zhongshitong will require enterprises to provide "raw material procurement vouchers" 3 months in advance to prove the independence of the production chain,so as to avoid being identified as "transfer pricing among affiliated enterprises".

III.Export Tax Rebate Optimization: Maximize Tax Rebate Amount Through Compliance

The efficiency of export tax rebate directly determines the cash flow of enterprises,and wrong HS code classification is the most common cause of delay.A furniture enterprise once misclassified "solid wood beds" as "panel furniture",resulting in wrong filling of the "material" column in the declaration elements,which was questioned by the customs as "inconsistent with the actual goods",and the tax rebate was delayed for 3 months.Zhongshitong’s "three-level review mechanism" can avoid such problems:

• First review: Preliminary review by the customs broker,verifying the consistency between declaration elements,commercial invoice and packing list
• Second review: Recheck by the agency,focusing on matching the "product name","material","specification and model" with the customs database (for example,the nickel content shall be specified for "stainless steel")
• Third review: Final review by financial consultants,checking whether the "number of items" and "unit" on the input invoice are consistent with those on the customs declaration form (for example,"100 sets" cannot be split into "1000 pieces")

Under the newly launched "digital tax rebate" policy in 2026,the agency shall guide enterprises to complete the following: ① Bind the electronic port IC card with the electronic tax bureau; ② Receive feedback from the tax authority within 24 hours after the declaration data is uploaded; ③ Prepare the Price Explanation Letter and Similar Product Price Comparison Form in advance for "doubtful data".

IV.Foreign Exchange Collection Security Guarantee: From "Passive Collection" to "Active Risk Control"

Foreign exchange collection risks mainly come from three dimensions: exchange rate fluctuation,inconsistent payment subject,and fund freezing.A textile enterprise once encountered bank refusal of payment because the customer paid through an "offshore company" which was inconsistent with the contract signing subject.Zhongshitong adopts the "three-dimensional risk control model":

• Contract pre-audit: Require the signing subject to be consistent with the payment subject,and supplement the "offshore company guarantee letter" (for example,Hong Kong companies shall indicate "director signature + company seal")
• Settlement method optimization: Adopt the combination of "30% advance payment + 70% sight letter of credit" for high-risk countries (such as Argentina and Turkey) to avoid full TT collection
• Exchange rate locking: Cooperate with banks to provide "forward foreign exchange settlement + option hedging" services.The fluctuation range of EUR/RMB will expand to ±5% in 2026,and locking the exchange rate in advance can reduce the exchange loss of enterprises by more than 12%

Special reminder: With the escalation of international sanctions in 2026,the agency shall verify: ① Whether the payment path involves sanctioned countries (such as Iran and North Korea); ② The update of the "sensitive country list" in the SWIFT system,to avoid fund freezing caused by "third-party transfer".

Conclusion: "Gold Standards" for Selecting Agencies in 2026

When selecting import and export agencies,enterprises shall focus on the following aspects: ① Whether it has the linkage capability of "Shanghai customs broker + national port network"; ② Whether it can provide the full-chain services of "certification pre-audit + anti-dumping early warning + tax rebate optimization + foreign exchange collection risk control"; ③ Whether it has technical tools such as "HS code database + intelligent verification of declaration elements".With 20 years of frontline experience,Zhongshitong has helped more than 5,000 enterprises achieve "99.7% compliance customs clearance rate and 40% shorter average tax rebate cycle",laying a solid foundation for the global layout of enterprises.
