2026 Raw Material Import Customs Clearance Full Process Guide: Practical Manual on Avoiding Pitfalls in Customs Valuation and Inspection

2026 Core Compliance Nodes for Raw Material Import Customs Clearance

The core logic of raw material import customs clearance is placing compliance first.All risk screening actions must be completed 7 days before cargo arrival to avoid port storage charges and credit deductions caused by post-arrival document supplements or amendments.As the largest raw material import port in the country,Shanghai Port achieved full-process online digitization for pre-inspection,customs valuation,and animal and plant quarantine in 2026.Eligible cargo can enjoy the "Advance Declaration,Two-Step Declaration" green channel,compressing clearance time to as fast as 2 working days.

HS Code Pre-classification and Declaration Element Verification

HS code classification is the first gate of customs clearance.Classification deviations directly lead to incorrect tax rate application and missing regulatory licenses,potentially triggering fines of up to 20% of the cargo value.In 2026,Customs updated classification rules for 320 types of raw materials.The determination standards for fine chemical raw materials,food contact materials,and animal and plant-derived raw materials were further refined.Before declaration,cross-verification of 12 declaration elements including brand,model,material,composition percentage,and processing craft must be completed to ensure 100% matching with the physical goods.

Regarding license processing,approval cycles vary significantly for different raw material categories.The approval cycle for animal and plant quarantine permits is 10-15 working days,and the operation filing cycle for hazardous chemical raw materials is 20 working days.All licenses must be processed before cargo shipment to avoid the risk of return due to inability to declare upon arrival.

Core Actions for Raw Material Import Customs Clearance Cost Control

In the landed cost of raw material imports,customs clearance related fees can account for 8%-15%.Optimizing advance actions can effectively compress unnecessary expenditures.Core actions include:

• Retrieve the median customs valuation of the same category at Shanghai port for the past 3 months in advance.Control the deviation of the declared price to within 5% to avoid detention caused by price negotiation,saving up to 3000 RMB in demurrage per 20-foot container.
• Verify the completeness of the Certificate of Origin endorsement in advance for raw materials originating from RCEP member countries.In 2026,12 new types of polymer materials and agricultural products were included in the zero-tariff coverage,reducing import tariffs by up to 15%.
• Arrange overseas pickup and title verification in advance for raw materials imported under EXW terms.Avoid operational gaps during overseas holidays such as Christmas and Ramadan.Completing document pre-audit 7 days in advance can compress overall clearance time by 40%.
• Check the compliance qualifications of exporters in advance for raw materials on the anti-dumping list.Avoid full recovery of anti-dumping duties and penalties caused by fake origins or under-reported prices,avoiding confiscation risks of up to 200% of the cargo value.

The Delivery Order fee trap under FOB terms is a common hidden expense.Many overseas forwarders charge additional equipment operation fees and document fees upon arrival,with amounts reaching up to 3 times the public quote.Zhongshitong’s global agent network connects directly with overseas shipping companies.All fee details are publicized in advance with no hidden charges,saving up to 1200 RMB per container on D/O related costs.

Guide to Avoiding Common Customs Clearance Risks

In March 2026,a new material enterprise in Suzhou imported 20 containers of palm oil-based degradable raw materials from Malaysia,requiring clearance and delivery for production orders within 7 days.During self-declaration,the application was rejected by Customs because the Certificate of Origin did not bear the RCEP country of origin marking,with an expected detention time of over 10 days.Upon engagement,we immediately activated the port emergency channel,coordinated with the overseas supplier to endorse the Certificate of Origin within 24 hours,and completed HS code pre-classification and pre-inspection in advance.The deviation between the declared price and the customs valuation median was only 2.1%.Ultimately,clearance took 2 working days,enjoying a 9% tariff reduction,saving the enterprise a total of 127,000 RMB and ensuring on-time delivery of production orders.

Addressing common pain points for small and medium import enterprises,Zhongshitong leverages the port resource advantages of its Shanghai headquarters to provide national port remote declaration services,covering core raw material import ports such as Tianjin,Qingdao,Shenzhen,and Ningbo.Enterprises do not need to interface with regulatory authorities at different ports themselves; all processes are uniformly audited by the risk control team at the Shanghai headquarters,avoiding compliance risks caused by regional policy differences.The global agent network covers 37 major raw material exporting countries in Southeast Asia,Europe,the Americas,and Latin America,providing full-link services including overseas pickup,CCIC inspection,international logistics,customs clearance,foreign exchange settlement,and distribution.This eliminates the need for enterprises to coordinate with multiple service providers,significantly reducing communication costs and operational risks.

All customs clearance operations are fully traceable.Enterprises can query declaration progress,tax details,and inspection status in real-time.The risk control team pushes information on tariff adjustments,anti-dumping warnings,and regulatory policy changes 7 days in advance,helping enterprises adjust procurement plans early and avoid cost fluctuations caused by policy changes.
