Chapter 42 covers articles of leather, saddlery and harness, travel goods, handbags and similar containers, articles of animal gut (other than silkworm gut), etc. The main raw material for goods in this chapter is leather or composition leather, but some headings also include similar goods made of other materials, such as sheets of plastics, textile materials, vulcanized fiber, etc. Classification within the chapter focuses on material and use, and it is one of the common chapters in customs classification. Heading 4202 includes trunks, suitcases, vanity cases, executive-cases, briefcases, school satchels, spectacle cases, binocular cases, camera cases, musical instrument cases, gun cases and similar containers; travelling bags, insulated food or beverage bags, toilet bags, rucksacks, handbags, shopping bags, map-cases, cigarette cases, tobacco pouches, tool bags, sports bags, bottle-cases, jewellery boxes, powder boxes, cutlery cases and similar containers, of leather or of composition leather, of sheeting of plastics, of textile materials, of vulcanized fibre or of paperboard, or wholly or mainly covered with such materials or with paper. Code 420249 is a six-digit subheading. The first two digits 42 represent Chapter 42, i.e., articles of leather, saddlery and harness, travel goods, handbags and similar containers, articles of animal gut. The 3rd-4th digits 02 represent heading 4202, covering various travel goods, handbags and similar containers. The 5th-6th digits 49 represent subheading 4202.49, i.e., 'Backpacks made of other materials'. Under heading 4202, subheadings are divided by material: 4202.11 to 4202.19 for leather or composition leather; 4202.21 to 4202.29 for sheeting of plastics or textile materials; 4202.91 to 4202.99 for other materials. 4202.49 specifically refers to backpacks made of other materials (such as vulcanized fibre, paperboard, etc.), distinguished from backpacks made of leather, plastics, or textile materials. The product is a backpack, which belongs to the container category under heading 4202. Since the material of the backpack is not leather, composition leather, sheeting of plastics, or textile materials, but other materials (such as vulcanized fibre, paperboard, etc.), it is classified under 4202.49 'Backpacks made of other materials', rather than adjacent codes such as 4202.11 (leather), 4202.21 (sheeting of plastics), or 4202.31 (textile materials).

Product Name: The Chinese and foreign language name of the declared goods should be accurately described as 'Backpack' or '背包', avoiding general terms like 'bag' or 'sack'. Material: Detailed description of the main materials used to make the backpack, such as vulcanized fibre, paperboard, plastics, textile materials, etc., and indicate the proportion of each material. Brand: Declare the brand name of the backpack (if no brand, fill in 'no brand'). Brand affects intellectual property and price, and must be declared truthfully. Model: Declare the model or item number of the backpack for identification and customs inspection. Use: Explain the use of the backpack, such as daily use, travel, student use, etc. Use affects classification but is not the main factor. Specifications and Dimensions: Declare the dimensions (length, width, height) and capacity of the backpack as auxiliary declaration elements. Whether the surface has a coating: If the backpack surface has a plastic or textile material coating, declare the coating material and thickness, which may affect classification. Processing Method: Explain the processing method of the backpack, such as sewing, gluing, etc., to assist in classification. Product Name: Backpack; Material: Vulcanized fibre (main material), no surface coating; Brand: ABC; Model: BP-2024; Use: Daily use; Specifications and Dimensions: 40cm×30cm×15cm; Processing Method: Sewing. Material declaration not specific, such as only writing 'other materials' without listing vulcanized fibre, paperboard, etc., leading to classification disputes. Confusing 'sheeting of plastics' with 'plastics'. If the backpack is made of sheeting of plastics, it should be classified under 4202.21, not 4202.49. Ignoring coating information. If the surface has a plastic coating that constitutes the main characteristic, it may be classified under 4202.21 or 4202.31.

The core basis for classification is the material of the backpack. According to the Import and Export Tariff and the Explanatory Notes, subheadings under heading 4202 are divided by material: leather or composition leather (4202.11-4202.19), sheeting of plastics or textile materials (4202.21-4202.29), other materials (4202.91-4202.99). The prerequisite for classifying a backpack under 4202.49 is that its main material is neither leather, composition leather, nor sheeting of plastics or textile materials, but other materials such as vulcanized fibre, paperboard, etc. If the backpack is made of multiple materials, it should be classified according to the main material, and if necessary, refer to General Interpretative Rules 3(b) or 3(c). 420211 Backpacks of leather or composition leather: Material is leather or composition leather, fundamentally different from 420249 backpacks of other materials. 420221 Backpacks of sheeting of plastics: Material is sheeting of plastics, which usually refers to plastic sheets, plates with thickness exceeding 0.25 mm, different from vulcanized fibre, paperboard, etc. in 420249. 420231 Backpacks of textile materials: Material is textile materials, such as canvas, nylon fabric, etc., different from 420249 backpacks of other materials. 420291 Backpacks of other materials (other subheading): 420291 is for backpacks of other materials, but usually refers to other materials not specifically listed, while 420249 specifically refers to backpacks. They are at different subheading levels; 420291 is for other materials not elsewhere specified, 420249 is for backpacks of other materials. Confirm whether the main material of the backpack is vulcanized fibre, paperboard, etc., not leather, sheeting of plastics, or textile materials. Check whether the backpack surface has a plastic or textile material coating, and whether the coating constitutes the main characteristic. Verify whether the backpack belongs to the container category under heading 4202, not other headings such as 4203. Confirm whether the use of the backpack is for personal carrying items, not special tool bags, etc. Check whether the declaration elements are complete, including material, brand, model, etc.

If a backpack is made of multiple materials, how to determine the main material? According to General Interpretative Rule 3(b), it should be classified according to the material that gives the goods their essential character. Usually, the material with the largest proportion by weight or value is the main material, but comprehensive consideration is needed. If it cannot be determined, refer to customs advance classification decisions. What is the difference between 420249 and 420291? 420249 specifically refers to backpacks of other materials, while 420291 is for other containers of other materials (such as tool bags, sports bags, etc.). Both belong to other materials, but different subheadings; backpacks should be classified under 420249. Does a plastic coating on the backpack surface affect classification? If the plastic coating constitutes the main characteristic, it may be classified under 420221 (backpacks of sheeting of plastics). But if the coating only serves a protective function, it is still classified according to the base material. Judgment should be based on coating thickness and proportion. How to inquire about the import tax rate for 420249? It can be queried through the General Administration of Customs website, China International Trade Single Window, or the Import and Export Tariff. Tax rates may change due to country, trade agreements, etc.; it is recommended to refer to the latest published information. Is the HS code for backpacks globally unified? The first six digits of the HS code are globally unified, but countries may subdivide the last four digits. 420249 is a six-digit subheading; countries may extend it. When exporting, confirm the destination country's code. How to fill in the 'Material' column during declaration? It should list the main materials and their proportions in detail, such as 'vulcanized fibre 70%, polyester 30%'. Avoid general filling like 'other materials' to prevent customs queries. Does classifying a backpack under 420249 require special documents? General trade imports require basic documents such as contract, invoice, packing list, bill of lading. If involving a brand, provide authorization. Specific requirements are subject to customs. How to declare for cross-border e-commerce retail export of backpacks? Cross-border e-commerce retail export requires declaration through cross-border e-commerce platforms, filling in HS code 420249, and truthfully declaring product name, material, brand, etc. Simplified declaration policies may apply, but conditions must be met.
