1. What is available on the website
The LAIYI source catalog contains 6,483 product records across ten source brand labels. These are catalog records, not a live-stock count or a statement that every item has confirmed fitment. English and Russian pages provide OEM search and inquiry routes.
Known references can be searched directly. For a list spanning several parts or brands, use Upload Parts List and keep the original OEM numbers intact.
2. Three checks for your next inquiry
Read the OEM search guide before selecting a record, then compare the proposed supply option and prepare the application evidence. The article on genuine versus aftermarket parts helps separate manufacturer identity from a marketing label.
- Preserve the full part number and suffixes.
- Connect the component to the actual vehicle or assembly.
- Ask the offer to identify the actual manufacturer and supply option.
3. Keep a multi-line request consistent
Use stable line IDs and file names for supporting photographs. Include quantities and units. When a number is missing, say so and provide the identification evidence. A structured list makes clarifications easier to follow than disconnected messages.
4. What this issue does not infer
We do not identify “hot OEMs”, regional demand or a best-selling brand from an initial catalog or early search-engine discovery. Those claims need a defined observation period and real buyer activity. Catalog size and search indexing are different measures.
Future issues can discuss anonymized, sufficiently supported patterns once such evidence exists. No buyer's contact details or vehicle identifiers are published in this issue.
5. Bring a checkable request
Search your OEM at chntruckparts.com, send a reviewed RFQ selection or upload a parts list. Include the information needed to ask specific questions. Application, availability and commercial conditions are confirmed during the individual review.
