Customs declaration for machinery and equipment requires seven categories of core documents: the customs declaration form, commercial invoice, packing list (gross/net weight and volume must match), export contract, HS Code classification (Chapter 84 for machinery), declaration elements (brand/model/intended use/material), and regulatory certificates (such as CIQ clearance certificates, filing for used electromechanical equipment, or specific certification documents based on type). An electronic letter of authorization is also required for agency declarations—consistency between the documents and the actual goods is critical during inspections.
I.
Basic Documents
Customs Declaration Form (electronic filing; includes HS Code and declaration elements); Commercial Invoice (product name/model/quantity/unit price/total price; must show the agent’s header); Packing List (gross weight/net weight/volume/number of packages; must match actual goods); Export Contract (terms between buyer and seller)—this “four-piece set” is standard for customs declaration; data inconsistencies lead directly to document rejection or physical inspection.
II.
HS Code and Declaration Elements
HS Classification (Chapter 84 for machinery: classified by function, e.g., 8443 printing presses, 8479 special-purpose machinery); Declaration Elements (product name/brand/model/intended use/material/power/condition—new or used); Regulatory Conditions (statutory inspection/licenses/3C certification based on the code)—an incorrect HS Code leads to errors in both tax rates and regulatory requirements (as tax rebate rates are also determined by the HS Code); if classification is uncertain, have the customs broker perform a pre-classification review.
III. Regulatory Documents
Commodity Inspection/Clearance Certificates (for equipment on the statutory inspection list: test reports + inspection declaration; filing for used electromechanical equipment exports); Certification Documents (CE/UL certificates accompanying the goods, depending on the destination market); Hazardous Goods Assessment (for dust-generating or chemical-related equipment); Dual-Use Item Permits (for controlled equipment)—regulatory document requirements are determined by equipment type and HS code (customs will detain goods if declared without the necessary permits).
IV.
Customs Declaration Agency Documentation
Electronic Authorization (Letter of Authorization for Customs Declaration); Broker Qualifications (Authorized Customs Declaration Enterprise); Tax/Duty Deposits (generally no tax for exports, except for special categories); Inspection Cooperation (presence required during customs inspections/submission of supplementary data)—handled by a customs broker (requiring qualifications and experience); for large-scale equipment, full-service agency handling is recommended (agency fees for machinery exports range from 1% to 5% of the FOB value).
V.
Notes for Overseas Buyers
First, HS Code Confirmation (ensuring tariff codes match between the exporting and importing countries); second, Document Consistency (alignment of the commercial invoice, packing list, and sales contract); third, Brand Authorization (using authorized brands for declaration of OEM/branded equipment); fourth, Used Machinery Filing (registration for the export of second-hand equipment); fifth, Destination Port Clearance Documents (Bill of Lading, Invoice, Certificate of Origin)—ensure the “seven-piece set” of declaration documents is complete (declaration form, invoice, packing list, contract, HS code, declaration elements, and regulatory certificates);
ensure document consistency and pre-verify HS codes to avoid inspection delays.
