Case background: Typical analysis of thermostat import

In 20221 February, we successfully handled a batch of industrial thermostats through Nansha Nanwei Terminal.Import ClearanceThis type of temperature control equipment falls under HS code 8536 for electrical devices, featuring typical electromechanical product characteristics: complex technical parameters, professional declaration elements, and strict customs supervision requirements.

Breakdown of customs clearance process: Control of 7 key nodes

In actual operations, we strictly control the timeliness of each link:

• Declaration document preparation stage: Special attention to CE certification documents for equipment testing instructions, andIt is recommended to verify through the following methods:Applicability of FTA tariff preference clauses. Among them, the thermostats rated voltage, control accuracy and other declaration elements directly affect classification accuracy.
• Terminal operation procedures: Utilizing the "pre-declaration" model at Nansha Port, document pre-review is completed 72 hours before the vessel's arrival, thereby reducing the cargo's dwell time at the port.
• Customs inspection phase: 4: For common inspection focus points of mechanical and electrical products (such as3C5 certification compliance), we prepare technical parameter comparison tables in advance to control inspection time within 1 working day.

III. MachineryEquipment Imports7s three major risk controls

8 Combining 15 years of agency experience, we have summarized special supervision points:

1. Disputes over commodity classification: 9: Thermostats are easily confused with temperature sensors (HS9025) in classification. We provide product working principle videos to assist customs understanding.
2. Valuation risk: For German imported equipment, apply the "deductive value method" to justify the declared price and avoid customs clearance delays due to price inquiries.
3. Wooden packaging quarantine: 13: Strictly implement IPPC mark inspections, complete fumigation certificate filing in advance to avoid equipment exposure risks from unpacking quarantine.

IV. Practical techniques for improving clearance efficiency

15 In this case, we compressed the overall clearance time to 3 working days through:

• Adopt the "two-step declaration" model: first submit a summary declaration for quick cargo pickup, then complete the full declaration within 14 days.
• Connect with the "Smart Image Review" system of Nansha Customs to pre-classify X-ray inspection images of thermostats.
• 18 Using tariff guarantee insurance instead of traditional deposits to reduce tax payment time

V. Nationwide multi-port collaborative service network

20 Besides Nansha Port, we have professional teams in Yangtze River Delta (Shanghai), Pearl River Delta (Dongguan, Foshan), and West Coast Economic Zone (Xiamen), able to recommend optimal clearance solutions based on client needs:

26 Dongguan Humen	27 Processing trade verification convenience	28 Bonded maintenance equipment

VI. Industry trends and policy outlook

30 With RCEP implementation, we recommend importers focus on:

• Impact of origin accumulation rules on tariffs for Japanese-made temperature control equipment
• The tax optimization opportunities brought by the "VAT General Taxpayer" pilot program in Nansha Comprehensive Bonded Zone
• Customs General Administrations 2023 facilitation measures for importing scientific research equipment

This thermostat import case fully demonstrates that professional customs clearance planning can significantly reduce trade costs. Through our classification recommendations, one client successfully reduced the tariff rate from 8% to 5%, saving over 20,000 yuan in taxes for a single shipment.
