2026 Complete Guide to Aluminum Ingot Import Customs Clearance Process, Admission Requirements and Tariff Calculation Practices

Core Admission Requirements for Aluminum Ingot Import Customs Clearance

Aluminum ingots belong to non-ferrous metal bulk cargo; in 2026,their customs regulatory classification falls under HS Code 76011090,which is subject to statutory inspection.Before import,confirm whether the country of origin applies anti-dumping and countervailing duty rates to avoid high subsequent tariff losses.Core documents required for regular declarations include commercial invoices,packing lists,ocean bills of lading,certificates of origin,and Quality Inspection Certificates (MTC).Among them,the aluminum content,impurity proportion and other parameters marked on the MTC must be completely consistent with the declared information,otherwise the customs will directly seize the goods for rectification.

If the country of origin is an RCEP member state,you can enjoy zero tariff preferences with a valid certificate of origin.In 2026,the customs’ verification coverage for preferential tariffs on aluminum ingot imports under RCEP has increased to 27%.You need to confirm in advance whether the issuing authority,validity period,commodity classification and other information of the certificate of origin meet the requirements to avoid failing to enjoy tax reduction policies.

Customs Valuation Rules

In 2026,the customs’ valuation benchmark for imported aluminum ingots refers to the reasonable range of the London Metal Exchange (LME) spot price plus corresponding freight and insurance.If the declared price deviates from the range by more than ±3%,the valuation procedure will be directly initiated,requiring enterprises to submit trade chain documents to prove the authenticity of the price.Enterprises can prepare materials such as foreign exchange payment vouchers,upstream purchase contracts,cost details under EXW or FOB terms in advance to speed up the valuation process.Below is the comparison of conventional tariffs on aluminum ingot imports from different countries of origin in 2026:

CIQ Inspection and Weight Verification

Imported aluminum ingots are statutory inspection commodities; the inspection rate at Shanghai Port in 2026 is about 18%,and the main verification contents include whether the commodity quality meets the MTC marked standards,whether there is solid waste,and whether the markings comply with national standards.The weight verification mostly uses draft survey,and the error margin allowed by customs is ±0.5%.If the error exceeds the range,re-weighing is required and supplementary tariff payment or tax refund shall be made based on the actual weight.

At the end of 2025,Mr.Si,an aluminum ingot trader,imported 2,000 tons of aluminum ingots from Vietnam.The error between the loading port draft survey and arrival verification reached 1.2%,almost incurring additional tariff costs of 120,000 yuan plus 3 days of demurrage.We coordinated with overseas agents in advance to conduct a third-party draft survey at the loading port,corrected the weighing error in advance,and the customs directly recognized the declared weight after submitting the verification report,avoiding additional costs.Currently,we can link up with agent networks in 120 countries worldwide to complete loading port MTC verification and weight verification in advance,and resolve risks early to avoid disputes at arrival.

Common Risks and Pitfall Avoidance Guide for Aluminum Ingot Import Customs Clearance

• Document Discrepancy Risk: The consignee,cargo value and commodity classification information on the certificate of origin must exactly match the customs declaration.In 2026,the customs’ verification rate for RCEP certificates of origin has increased to 27%; once the information does not match,the preferential tariff rate will be directly canceled.You need to submit all documents for pre-examination 7 working days in advance to check for errors and omissions.
• Hidden Cost Risk: The free detention period for bulk carriers after arrival is generally only 3 days.If customs clearance is delayed due to document issues,daily demurrage will exceed 800 USD.When picking up documents,note that some shipping lines will charge additional document handling fees; confirm all cost details in advance to avoid unreasonable surcharges.
• Valuation Rejection Risk: If the declared price is 3% lower than the LME spot price for the same period,the customs will likely initiate the valuation procedure.You need to prepare complete trade chain documents in advance,including upstream purchase contracts,foreign exchange payment receipts,freight and insurance invoices,and third-party price verification reports,to avoid being required to pay supplementary tariffs based on customs valuation.
• Foreign Exchange Loss Risk: Aluminum ingot purchases are mostly settled in USD,and the interval from contract signing to foreign exchange payment is generally 1-3 months.Exchange rate fluctuations exceeding 2% will generate large foreign exchange losses.You can lock in forward exchange rates in advance to avoid exchange rate fluctuation risks.
