2026 Practical Guide to the Full Process of Agency Export Customs Declaration

Destination Port Certification and Compliance Details

In agency export customs declaration,destination port certification is the first invisible threshold for enterprises going global.In 2026,tariff reduction policies for RCEP member countries continue to deepen,and countries like Indonesia and Malaysia have shifted the inspection requirement for FORM R certificates of origin from "optional" to "mandatory".However,last year a furniture company failed to mark the "FORM R certificate of origin title information" in the remarks column of the customs declaration form,leading to the Indonesian customs at the destination port detaining the goods due to inconsistency between the certificate of origin title and the customs declaration title,resulting in additional demurrage fees for over 48 hours of cargo detention.

We recommend enterprises complete the "three documents matching" check before customs declaration: the declaration elements of the customs declaration form,contract,and packing list must be completely consistent,especially fields like "brand","model",and "material".For example,a mechanical parts exporter was rejected by Shanghai Customs for "unclear declaration elements" because the "material" column of the customs declaration form was incorrectly filled as "stainless steel" (actually 304 stainless steel).We avoided cargo delay by urgently submitting material certification documents and coordinating with customs to modify the declaration.

• Destination port certification list verification: within 72 hours before export,be sure to check the latest certification requirements of the destination country through the "Single Window" of the General Administration of Customs (e.g.EU cosmetics require ECOCERT certification,US FDA food contact material testing)
• Certificate of origin title matching: if involving RCEP member countries,note the "name of the certificate of origin title enterprise" in the remarks column of the customs declaration form to ensure consistency with the contract title
• Additional verification for sensitive commodities: for chemical products,confirm in advance that the MSDS matches the "commodity name" on the customs declaration form; for machinery,supplement with "CCC certification" (if exporting to EU)

Anti-dumping Early Warning and Tariff Risks

In 2026,global trade barriers show "precision" characteristics,and anti-dumping investigations by the US against Chinese furniture and the EU against Chinese aluminum products continue to intensify.A home appliance enterprise was imposed a 19.8% anti-dumping duty by the EU due to incorrect HS code classification (classifying "electric massage chairs" under the HS code of "manual massage chairs"),resulting in direct losses exceeding one million.

To avoid anti-dumping risks,three steps are required: 1.Update the target country’s tariff schedule through the "Anti-dumping Early Warning System" of the General Administration of Customs before March each year; 2.Verify before declaration whether the "material composition percentage" and "production process" of the commodity meet the requirements of anti-dumping tariff rules; 3.If involving sensitive commodities,apply for "commodity pre-classification" in advance (Shanghai Customs provides free pre-classification services).

• Anti-dumping duty query channels: log in to the "China Trade Remedy Information Network" or the "Tariff Query" module of the General Administration of Customs official website,and enter the HS code to obtain the current anti-dumping duty rate
• New anti-dumping monitored commodities in 2026: solar-grade polysilicon (EU),seamless steel pipes (US),textiles (India)
• Declaration element "material composition percentage" verification: for example,when exporting plastic toys,clearly state "ABS resin content ≥90%" in the "commodity specification" column of the customs declaration form to avoid being classified as "other plastics" (subject to different tariff rates)

Export Tax Refund Optimization and Declaration Element Verification

In 2026,export tax refund policies continue to be adjusted in a "precision-oriented" manner,and the tax refund rate for some commodities has been reduced from 13% to 9% (e.g.ceramic products).Enterprises need to accurately reflect the "tax refund rate corresponding code" in the declaration elements of the customs declaration form.For example,for "LED lamps" with a tax refund rate of 13%,note "LED lighting fixtures (tax refund rate 13%)" in the "commodity name" column to avoid tax refund delays caused by the system automatically matching incorrect tax rates.

A clothing exporter failed to fill in the "own brand" in the "declaration element - brand" column (the contract title was "ODM manufacturing"),resulting in the tax refund system failing to pass the review due to "brand inconsistency with actual export products".We coordinated with customs to modify the declaration elements and supplemented with a brand authorization letter,finally completing the tax refund within 15 working days,nearly 40% shorter than the industry average of 25 days.

• Self-inspection checklist for declaration elements (2026 Customs Key Points):
• The "brand" column must be the actual brand used (not the manufacturing brand)
• The "model" must be exactly consistent with the product nameplate (e.g."Model: A100" cannot be abbreviated as "A10")
• The "material" must be precise to "304 stainless steel" instead of "stainless steel"
• The "packaging method" must be consistent with the actual packaging unit (e.g."packed in cartons,20 pieces per carton" instead of "packed in cartons")

Foreign Exchange Collection Safety and Customs Declaration Coordination

In 2026,the State Administration of Foreign Exchange has tightened supervision over the "export foreign exchange collection to be verified account".If an enterprise fails to complete the "export foreign exchange collection path filing" through an agency,it may result in the account being frozen after collection due to "inconsistency between the foreign exchange collection source and the customs declaration form".A textile enterprise was returned by the bank as "unreal trade background" because it directly collected foreign exchange into a personal account,resulting in additional foreign exchange conversion costs.

We recommend enterprises complete the "foreign exchange collection path filing" before customs declaration: 1.Use the corporate account provided by the agency (Zhongshitong Shanghai Branch has opened a "cross-border foreign exchange collection green channel"); 2.Note specific methods such as "T/T telegraphic transfer" and "letter of credit" in the "foreign exchange collection method" column of the customs declaration form,and match with the bank slip; 3.For large foreign exchange collections (over $500,000),submit a "trade authenticity certificate" to the State Administration of Foreign Exchange 3 working days in advance.

Common Risk Warning List

• Hidden fee traps: In 2026,port surcharges have risen,with document transfer fees increasing from RMB 500 per ticket to RMB 800 per ticket.Need to confirm fee details with the agency in advance (Zhongshitong promises "one price per ticket,no hidden charges")
• Declaration element errors leading to rejection: In 2026,"declaration element errors" accounted for 68% of Customs rejection rates.It is recommended to use the "intelligent customs declaration pre-review system" (Zhongshitong has connected to the General Administration of Customs pre-review platform)
• Foreign exchange control risks: If the destination country is a foreign exchange control country like India or Brazil,note "prohibition of third-party foreign exchange collection" in the "remarks" column of the customs declaration form to avoid the foreign exchange collection path being blocked

As a well-established agency at Shanghai Port,we have summarized the "four-step compliance method" through 20 years of on-site practical experience: 1.Destination port certification list verification (72 hours in advance); 2.Accurate HS code classification (using the General Administration of Customs classification decision system); 3.Full-field verification of declaration elements (three documents matching); 4.Foreign exchange collection path filing (coordinated with the bank).These methods have helped over 3,000 enterprises avoid declaration rejection risks.In 2026,the average tax refund time has been improved to 18 working days,12 days shorter than the industry average.
