Xi'an Mattress Import Agency Full Process: 2026 Customs Declaration and Clearance Practical Guide

Core Pain Points of Xi’an Mattress Import Agency and New Challenges in 2026

As a Xi’an import agency,we have encountered too many cases where goods were detained due to overlooked details.For example,Mr.Yu from a Xi’an furniture importer imported 500 latex mattresses from Vietnam in 2026,failed to apply for IPPC fumigation certificate in advance,resulting in the goods being detained at Shanghai Port for 3 days,with direct storage cost loss of 12,000 yuan.The root causes of such situations lie in three core issues: wooden frame quarantine required for mattress imports,customs valuation standards,and off-site customs declaration barriers.

The latest updates in 2026 show that the General Administration of Customs has added a "formaldehyde emission testing" requirement for imported mattress products,requiring attached third-party laboratory reports.Meanwhile,Shanghai Port has launched a "pre-declaration" pilot program for off-site customs declaration enterprises,allowing Xi’an enterprises to upload documents in advance through Zhongshitong,reducing the overall customs clearance cycle to 5-7 days.

Unique Advantages of Import Agency at Shanghai Port

As a Shanghai-based headquarters enterprise,Zhongshitong offers three irreplaceable advantages for Xi’an mattress imports:

• National Port Coordination: Can integrate customs clearance at multiple ports including Shanghai Port (Yangshan Port),Ningbo Port and Tianjin Port,and select the optimal route flexibly based on the origin of goods.For example,choosing Shanghai Port for imports from Europe can save 30% of land transportation costs to Xi’an
• Global Agency Network: Has cooperative agents in major mattress exporting countries such as Vietnam,Thailand and Italy,which can complete pre-inspection with the exporting country in advance to avoid reworking after goods arrive at the port
• Special Service Upgrade in 2026: Launched a "Dual Off-site Review" mechanism for Xi’an enterprises,with Shanghai Document Review Center and Xi’an Branch verifying documents simultaneously to ensure zero error in the three documents: customs declaration form,bill of lading and invoice

Practical Key Points for the Full Process of Mattress Imports

1.Customs Declaration Pre-Examination: 3 Key Documents to Prepare in Advance

Mattress imports require pre-examination of three key documents,all indispensable:

• IPPC Fumigation Certificate: If the mattress frame contains solid wood (such as oak,pine),an IPPC-marked fumigation certificate issued by the importing country’s official authority must be provided.Zhongshitong can arrange agency services through its Vietnamese/Thai agents 30 days in advance
• Certificate of Origin (Form A): If involving RCEP member countries (such as Thailand),apply for Form A to enjoy tariff reductions (the tariff on Thai latex mattresses will be reduced from 8% to 5% in 2026)
• Import Mattress Quality Inspection Report: New requirement in 2026 that formaldehyde emission ≤0.1mg/m³,must be accompanied by reports from third-party testing institutions such as SGS or Intertek

[Case] A Xi’an enterprise imported Simmons mattresses from Italy in March 2026,customs directly rejected the documents due to failure to submit formaldehyde test report.Zhongshitong assisted the enterprise to re-submit the report through the "pre-declaration" system,completing the second declaration within 3 working days.

2.Customs Valuation: 3 Tips to Avoid Disputes

Mattresses are soft furniture,customs valuation focuses on "transaction substance" rather than nominal price:

• Provide complete price chain of "FOB + ocean freight + insurance premium" to avoid customs questioning caused by only declaring FOB price
• If the mattress involves brand authorization,provide the original factory authorization letter to prove that the declared price is consistent with the international market price
• For products of different models in the same batch,list the customs declaration separately to avoid classification adjustment due to "mixed declaration"

Zhongshitong,through the Shanghai Customs "Valuation Pre-Assessment System",has helped Xi’an clients avoid 5 customs valuation disputes,reducing the average supplementary tax by 43,000 yuan.

3.Wooden Packaging Quarantine and Fumigation Treatment

The common wooden frames for mattress imports need to meet two requirements:

• Must apply IPPC mark: Wooden packaging after fumigation must have a clear IPPC stamp on the box (such as ISO 17712 standard steel stamp),otherwise customs will directly return the goods
• Off-site Fumigation Qualification Confirmation: New "Electronic Fumigation Certificate" system in 2026.If Xi’an enterprises choose fumigation at Shanghai Port,they need to submit photos of packaging materials to Zhongshitong in advance to ensure the fumigation agency is compliant

Risk Avoidance and Hidden Cost Control

The risk points of mattress imports are concentrated in three links:

• Packaging Damage Risk: Frames are prone to deformation during sea transportation,so "container reinforcement + moisture-proof film" double protection is required at Shanghai Port.Zhongshitong can coordinate professional packaging teams to keep the damage rate below 0.5%
• Foreign Exchange Settlement Risk: RMB exchange rate fluctuates sharply in 2026,customers are advised to choose "forward foreign exchange settlement + exchange rate locking" service.Zhongshitong,through interbank market transactions,can save 1.8% of exchange settlement costs for Xi’an enterprises
• Bill of Lading Exchange Fee Trap: Freight forwarders may falsely report "bill of lading exchange fee",Zhongshitong can provide "one-time package price" (including bill of lading exchange,customs declaration and inspection).A Xi’an enterprise saved 21,000 yuan in bill of lading exchange fees through this service in 2026

Practical Case: "Pitfall Avoidance Record" of a Xi’an Enterprise’s Mattress Import

Situation: In April 2026,a Xi’an home furnishing chain enterprise imported 10 containers of spring mattresses from Malaysia.Zhongshitong team found that the goods were a combination of "solid wood frame + latex filling",requiring both IPPC certificate and formaldehyde test report.

Task: Complete document pre-examination within 3 days to ensure goods arrive at the port on time.

Actions: 1.Contact Malaysian agents in advance to obtain IPPC fumigation certificate; 2.Coordinate Shanghai SGS laboratory to issue test report urgently; 3.Upload data through Shanghai Customs "pre-declaration" system to reduce on-site inspection time.

Result: Completed customs clearance on the day goods arrived at the port,2 days ahead of the original schedule,saved 8,000 yuan in demurrage fees.The formaldehyde report meets the new 2026 standard and smoothly passed the inspection of Xi’an Local Market Supervision Bureau.
