2026 Complete Process for Stone Import Agency Customs Clearance with Latest Regulatory Requirements & Pitfall Avoidance Guide

Preparatory Work for Stone Import Agency Customs Clearance

Before importing stone,precise HS code classification must be completed.Common imported categories like marble,granite,and slate are primarily classified under chapters 2515,2516,and 6802,with Most-Favored-Nation (MFN) tariffs ranging from 3% to 15% depending on the classification.In 2026,stone originating from RCEP member countries such as Turkey,India,and ASEAN can enjoy tariff preferences up to 0% with valid Certificates of Origin.However,note that China still imposes anti-dumping duties of 10%-24% on stone from some EU and North American origins.Verify the applicable tariff rates for the origin before import to avoid unexpected tax liabilities.

I previously worked with Mr.Tong,a home decoration materials supplier from Ningbo.In February 2026,he imported a batch of Iranian Cream Travertine marble,planning to have it arrive before the March peak season for sales.The specifications on his self-prepared documents were listed as 60*60cm,but the actual goods measured 62*62cm.He submitted the declaration without prior verification,which triggered a customs inspection,resulting in 12 days of port detention and generating RMB 87,000 in container demurrage and storage fees.He completely missed the sales season.Such problems can be entirely avoided by conducting a pre-declaration document review.

Core Operational Process for Stone Import Customs Clearance

1.Pre-Declaration Document Review & Pre-Shipment Inspection

Stone is a category prone to carrying soil and pests.In 2026,customs introduced a pre-review requirement for stone radioactive indicators.Relevant risks must be identified during the document review stage.Key documents required include:

• Basic Trade Documents: Packing List,Commercial Invoice,Trade Contract,Ocean/Air Waybill.For stone originating from RCEP member countries,ensure the HS code,value,and specifications on the Certificate of Origin exactly match the declaration data; otherwise,tariff reductions cannot be claimed.
• Quarantine Documents: Phytosanitary Certificate,Fumigation Certificate.If wooden packaging is used,it must bear the IPPC mark.Goods without proper treatment will be directly ordered for re-export.
• Special Category Documents: For importing endangered stone varieties like Turquoise or Agate,an "Import Permit for Endangered Species" must be obtained in advance.Declarations without proper certification will be directly transferred to the anti-smuggling department.

2.Port Declaration & Price Review Response

Currently,there are three modes for stone import declaration,each with significantly different applicable scenarios,advantages,and disadvantages.Refer to the table below:

In 2026,customs’ stone price review model added a price comparison threshold for goods of the same category and origin within the same quarter.If the declared price is more than 10% below this threshold,it will directly trigger a price review inquiry.Enterprises must provide supporting documents such as original factory invoices,payment proofs,and trade term details (freight and insurance breakdown for EXW/FOB/CIF) to avoid customs overvaluing the goods and increasing tax liability.

3.Inspection & Release for Delivery

Stone import inspections primarily focus on three aspects: first,whether radioactive indicators comply with national building material standards; non-compliant goods will be directly ordered for re-export.Second,whether undeclared other stone types or contraband are concealed.Third,whether declared elements (material,specifications,origin,processing method) match the physical goods.In 2026,Shanghai Port has implemented intelligent sorting for stone inspections.Goods from Category A credit enterprises enjoy priority inspection,reducing the average inspection time from 2 days to 4 hours.For goods passing inspection without issues,delivery can be arranged on the same day after tax payment.

Common Risks in Stone Import Clearance & Mitigation Strategies

Hidden cost traps during stone import are common pitfalls for many cargo owners.Ms.Mai,a stone wholesaler from Fujian,engaged a clearance agent in early 2026 who quoted 30% below market rate for importing a batch of Italian Carrara White marble.She did not verify the fee breakdown upfront and was later charged miscellaneous fees during clearance,including document exchange fees,inspection coordination fees,and interest on advanced port demurrage payments.The total cost ended up being RMB 52,000 higher than standard agency quotes.To avoid such common risks,consider the following strategies:

• Confirm HS code classification in advance.Engage an agent for pre-classification to avoid misclassification leading to overpaid duties or triggering anti-smuggling alerts.
• Maintain complete trade chain documentation for declared value.In case of a price review inquiry,submit supporting documents promptly for defense to shorten the review cycle.
• Investigate origin trade policies proactively.In 2026,China initiated new countervailing investigations on stone from some Southeast Asian origins.Verify applicable tax rates before import to avoid additional liabilities.
• Sign a clear fee agreement with the agent,listing all chargeable items to prevent subsequent hidden charges.
