How to Read Office Chair Product Numbers

The viewing of office chair product numbers should be determined based on specific coding systems, with common methods including the Harmonized System (HS) codes, internal enterprise material codes, and national standard barcodes for commodities. Details are as follows:

1. Harmonized System (HS) Code System
HS codes are standardized codes used for classifying goods in international trade. Office chairs are typically classified under HS category 9401 (Seats and their parts), with specific subheadings determined by function and material:

• Functional differences: Adjustable-height office chairs with 360-degree rotation are coded as 94013000; ordinary non-rotating chairs may fall under 94013900.
• Material differences: Wooden-framed seating is classified as 9401690090, while metal-framed seating is classified as 9401790000.
  Query methods: Authoritative codes can be obtained through the China International Trade Single Window, the General Administration of Customs website, or the 'Customs Classification Guide' WeChat official account. This system is applicable to import and export trade scenarios, with a focus on the impact of functional design and material on coding.

2. Internal Enterprise Material Code System
For ease of asset management, enterprises assign unique model codes to products (e.g., Sihoo's M57, C300). Model labels are commonly found in the following locations:

• Center area of the base of the five-star foot or support rod;
• Below or on the side of the connection between the backrest and the seat cushion;
• Bottom of the seat cushion.
  Labels typically indicate 'Model' or directly display the model code, allowing users to quickly identify the product model through physical labels. This system is applicable to enterprise production, after-sales, and inventory management scenarios.

3. National Standard and Commodity Barcode System
Office chairs circulating domestically must comply with relevant national standards, such as wooden office chairs adhering to GB/T 3324-2024 'General Technical Conditions for Wooden Furniture'. Their commodity barcodes (GTINs) can be queried through official channels of the China Article Numbering Center. This system is applicable to domestic sales scenarios, where consumers can obtain detailed product information by scanning the barcode or querying the code.

Core Logic: The viewing of office chair numbers should be based on the usage scenario, selecting the corresponding system—international trade prioritizes HS codes, enterprise asset management relies on internal model numbers, and domestic sales require querying commodity barcodes. Functional design (e.g., rotatability) and material are key factors in HS code classification, while physical labels and national standards provide supplementary support for other scenarios.
