Case background: Typical analysis of thermostat import

In 2022年1 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 stageSpecial 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 procedures2: Utilizing Nansha Ports advance declaration mode, complete document pre-review 72 hours before vessel arrival to reduce cargo dwell time at port.
• Customs inspection phase4: 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. For example, Indonesia has the SNI certification, Thailand has the TISI certification, and the Philippines has the BPS certification. It is necessary to confirm in advance the equipment voltage (such as 380V/50Hz in Thailand), the compatibility of the CE certification, and the proof of environmentally friendly materials.7s three major risk controls

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

1. Disputes over commodity classification9: Thermostats are easily confused with temperature sensors (HS9025) in classification. We provide product working principle videos to assist customs understanding.
2. Valuation risk11: For German imported equipment, use the deductive value method to demonstrate the rationality of declared prices, avoiding clearance delays due to price queries.
3. Wooden packaging quarantine13: 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:

• 16 Adopting the two-step declaration mode - submit summary declaration first for quick pickup, then complete full declaration within 14 days
• 17 Connecting with Nansha Customs smart image review system for pre-classification of thermostat X-ray images
• 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:

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
• Tax optimization opportunities under 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.
