Chengdu Import Customs Declaration Agency, Professional and Compliant Full-Service Import Customs Clearance Provider

Core Services and Practical Key Points of Chengdu Import Customs Declaration Agencies

As a core node of the New International Land-Sea Trade Corridor in western China,Chengdu’s import value increased by 18.7% year-on-year in 2026,with mechanical and electrical products,chemical products and food accounting for more than 70% of the total.Many enterprises encounter problems such as wrong HS code classification,customs valuation queries,and cargo detention due to incomplete documents during import customs clearance.Choosing a professional Chengdu import customs declaration agency is the core path to reduce risks.

Accurate HS Code Classification: Basic Prerequisite for Compliant Customs Clearance

In 2026,the General Administration of Customs upgraded the classification and supervision model of the national customs clearance system,and the supervision rate for enterprises with vague declarations or incorrect tariff code classification increased to 32%.Last year,a Chengdu-based machinery manufacturing enterprise imported German 5-axis machining centers,and incorrectly classified "5-axis simultaneous machining centers" as ordinary CNC machine tools,resulting in under-declared tariffs of RMB 210,000 and a fine of 0.5 times the underpaid amount.Professional agencies will conduct accurate classification in accordance with the 2026 Explanatory Notes to the Import and Export Tariff,combining parameters such as the number of equipment shafts,control system,and machining accuracy.At the same time,they will check the consistency between declaration elements and actual goods in advance to avoid inspection and cargo detention due to mismatches in brand,model,and material.

Customs Valuation Risk Prevention and Control: Avoid Hidden Expenses

In 2026,customs has intensified verification of declarations related to transaction prices such as royalty fees and after-sales rebates.About 27% of import enterprises have been audited for failing to truthfully declare royalty fees.A Chengdu-based imported cosmetics brand was once required by customs to pay supplementary tariffs and late fees totaling RMB 380,000 for failing to declare brand licensing fees.Professional agencies will review import contracts in advance,clarify the scope of royalty fees and include them in the total declared value.Meanwhile,in view of the valuation preferences of Chengdu Port,they will prepare transaction price files of similar products in advance to respond to customs price queries.In addition,it is necessary to guard against hidden traps such as document exchange fees and demurrage fees.Some local agencies charge extra undisclosed storage fees,while formal agencies will issue a detailed fee list in advance,clarifying the basis for each expense.

Commodity Inspection Pre-audit and Animal and Plant Quarantine: Key Link for Compliant Access

Commodity inspection requirements vary significantly for different categories of imported products: food products require official overseas health certificates and production date certificates; animal and plant products require advance processing of Entry Animal and Plant Quarantine Permit; mechanical and electrical products require pre-shipment inspection.In 2026,the preferential tariff policies for RCEP member states have been further refined.For mechanical and electrical products imported from ASEAN,a 5% to 10% tariff reduction can be enjoyed with a compliant certificate of origin.Professional agencies will pre-audit commodity inspection documents in advance,and conduct pre-inspection of the packaging and labeling of goods arriving at the port,to avoid unqualified commodity inspection and delayed customs clearance due to non-compliant packaging.

Import License Processing: Full Category Qualification Coverage

In 2026,the approval period for import licenses for some sensitive categories,including automatic import licenses,import and export certificates for endangered species,and dual-use item licenses,has been extended to 7 to 10 working days.Cross-regional customs declaration agencies can rely on national port linkage resources,with the Shanghai headquarters coordinating off-site approval,and then connecting with the customs clearance process at Chengdu Port,reducing the time cost of qualification processing.For example,a Chengdu-based new energy enterprise importing lithium ore applied for an automatic import license in advance through a cross-regional agency,and completed customs clearance 3 days earlier than using a local agency,avoiding port demurrage fees.

• Prepare a full set of import documents in advance: contract,invoice,packing list,bill of lading,certificate of origin,etc.to avoid demurrage fees caused by supplementary documents after the goods arrive at the port
• Verify that the declaration elements are consistent with the actual goods: information such as brand,model,specification,and material must be completely matched,to avoid customs supervision,inspection and cargo detention
• Confirm tariff rates in advance: Some RCEP member states adjusted tariffs in 2026,apply for certificate of origin in advance to enjoy preferential tariff rates
• Clarify fee details: Reject unsubstantiated hidden charges,and require the agency to issue a complete fee list
