District 5: Auto Parts & Car Accessories
District 5 of the Yiwu International Trade Mart is the primary hub for automotive aftermarket products, concentrated on the 4th floor. It offers a dense cluster of suppliers specializing in car and motorcycle accessories, auto electronics, repair tools, and decorative items, often with low minimum order quantities suitable for small and medium importers.

The Core Auto Parts Hub on Floor 4
District 5’s 4th floor is the dedicated center for automotive aftermarket products, offering a dense cluster of suppliers for wholesale buyers.
This zone specializes in car and motorcycle accessories, auto electronics, repair tools, and decorative items, with many booths operating as direct factory outlets or long-term trading offices.
Buyers can access new product designs and negotiate flexible order terms directly with suppliers, making it a primary destination for sourcing competitively priced parts.
Product Range and Order Flexibility
The market focuses on cost-effective, mass-market accessories and universal-fit parts rather than OEM-grade components, including items like seat covers, floor mats, lighting, filters, and brake pads.
A key advantage for small and medium importers is the low minimum order quantity (MOQ), often as low as one carton per item, which is ideal for test marketing and small wholesalers.
Suppliers frequently update their catalogs with style variations, positioning products for high turnover in budget-conscious retail and online channels.
Sourcing for Specific Markets: The Korean Vehicle Example
While District 5 vendors primarily sell Chinese-made aftermarket parts, many buyers source compatible accessories and universal parts for global brands, including Korean vehicles like Hyundai and Kia.
This contrasts with specialized Korean exporters who supply genuine or OEM parts; Yiwu offers a budget-friendly channel for non-genuine, compatible items.
This distinction helps importers choose between cost-effective aftermarket solutions from Yiwu for general retail and higher-spec genuine parts from specialized exporters for authorized service networks.
District 5 Layout & Comfort (Newest Building)
District 5’s newest residential buildings offer modern, comfortable living spaces designed for efficiency and convenience. With contemporary layouts, a range of apartment sizes, and integrated amenities, the compound provides a quieter, more functional environment suitable for both residents and business travelers on sourcing trips.

Modern Design and Building Layout
District 5’s newest residential buildings feature contemporary mid-rise designs with modern façades and large windows to maximize daylight and usable space.
The layouts prioritize clear circulation and separate service zones, offering a more comfortable and efficient living environment compared to older, deeper-plan blocks found in legacy industrial districts.
Apartment Sizes and Flexible Floor Plans
The building offers a wide range of unit sizes, from compact 2-bedroom apartments starting around 136 m² to larger 3-bedroom layouts from about 188 m², with some units reaching over 700 m².
This size mix allows for flexible use, enabling sourcing professionals to use larger apartments for storage, sampling, and meetings, while smaller units suit shorter stays.
Amenities and Daily Convenience
The compound is integrated with a retail mall and two clubhouses, providing shopping, dining, fitness, and social spaces within walking distance.
This amenity base reduces the need for cross-city trips, enhancing comfort for business travelers on sourcing trips for textiles or auto parts.
Environment and Suitability for Business Stays
Designed as a mixed-use residential compound with greenery and controlled traffic, District 5 provides a quieter and better-ventilated environment compared to adjacent industrial zones.
The modern buildings and amenities make it suitable for hosting small sourcing teams, with multi-bedroom apartments that can be configured to include sample rooms and quiet negotiation spaces.
The “Imported Goods” Section: Selling Into China
Selling imported goods into China’s wholesale districts requires navigating a national import regime. Foreign sellers typically work through licensed Chinese entities, comply with HS codes, tariffs, VAT, and meet strict product standards and labeling rules for textiles, cosmetics, and auto parts.
| Product Category | Key Compliance Requirements | Typical Duty & Tax Range |
|---|---|---|
| Textiles & Apparel | GB standards, fiber content labeling, safety tests (formaldehyde, azo dyes) | 5-16% MFN duty + 13% VAT |
| Korean Cosmetics | NMPA registration/filing, Chinese ingredient labeling, safety data | Duty varies + 13% VAT + possible consumption tax |
| Auto Parts | CCC certification for safety items, technical standards, labeling | 6-14% MFN duty + 13% VAT |
| Industrial Inputs (e.g., POM) | HS code accuracy, potential anti-dumping investigations | Standard duty + possible anti-dumping duties (e.g., 74.9%) |

How Importing into China Works for Foreign Sellers
Foreign sellers typically cannot import directly; they must work through a licensed Chinese entity like a trading company or logistics provider.
Common business models include selling FOB to a Chinese buyer, using a local import agent, or leveraging cross-border e-commerce bonded-warehouse models for items like cosmetics.
The process is governed by China’s national import regime, including HS code classification, tariffs, VAT, and meeting product-specific technical standards.
Costs, Duties, and Required Documentation
Imports are subject to MFN customs duties (e.g., 5-16% for textiles, 6-14% for auto parts), a 13% import VAT, and sometimes consumption tax.
Anti-dumping duties, like the 74.9% rate on specific POM copolymers, can apply to certain industrial inputs.
Core documentation includes a commercial invoice, packing list, bill of lading, customs declaration, and any required inspection or certification certificates (e.g., for textiles or CCC for auto parts).
Product Compliance: Standards, Testing, and Labeling
Goods must meet mandatory Chinese standards (GB/GB-T) and may require certifications like CCC for safety-critical auto parts.
Korean cosmetics require NMPA registration or filing, which involves detailed safety data and can take several months.
All products sold in China require compliant Chinese-language labels detailing composition, care instructions, origin, and manufacturer/importer details.
Logistics, Risks, and Strategic Considerations
Goods typically move via ocean freight to major ports like Shanghai or Ningbo, with air used for time-sensitive items; bonded warehouses allow for duty deferral.
Key risks include customs delays from misclassification, fines for non-compliance, and intellectual property infringement in segments like branded cosmetics.
Sellers should monitor shifts in trade policy and technical standards, and proactively register trademarks in China to protect their brands.
