The Complete Guide to Bag Manufacturing: 100+ Industry Terms Every Buyer Should Know
Whether you are launching a private label handbag line, sourcing backpacks for your retail chain, or planning your first OEM order with a Chinese factory, this guide walks you through every term you will encounter — from materials and hardware to production, shipping, and customs.
1. Why This Glossary Matters for Your Sourcing Project
The bag and luggage industry has its own language. When you communicate with a bag manufacturer, a bag factory, or any OEM/ODM bag supplier in China, you will hear dozens of specialized terms every day. Knowing them helps you avoid miscommunication, negotiate better pricing, and ensure your final product matches your vision exactly.
Range is a Guangzhou-based bag manufacturer with over a decade of experience serving global brands. We have prepared this glossary to help importers, brand owners, and sourcing managers speak our language — and the language of the global bag industry.
2. Bag Types: Understanding the Products You Can Source
Before you start a custom project, identify the bag type that matches your market. The most common categories in custom bag manufacturing include:
2.1 Backpacks
The most popular style worldwide — a bag carried on the back with two symmetrical shoulder straps. Includes business backpacks, casual backpacks, school backpacks, travel backpacks, and outdoor backpacks. View our backpack collection →
2.2 Sling Bags and Crossbody Bags
Single-strap or long-strap bags worn diagonally across the body. Hands-free, lightweight, and ideal for travel and commuting. View our sling bag collection →
2.3 Handbags and Tote Bags

2.4 Travel Bags and Duffle Bags
Roomy rectangular bags with top handles, designed for short trips, gym, and weekend travel. Also called weekender bags or overnight bags.
2.5 Laptop Bags and Business Bags
Bags with a padded laptop compartment sized for 13", 15", or 17" devices. Essential for business and student use. View our laptop bag collection →
2.6 Smell Proof Bags
Bags with carbon-lined compartments and sealed zippers to block odor — popular in cannabis, coffee, and outdoor markets. View our smell proof collection →
2.7 Cooler Bags, Pet Bags, and Wallets

3. Materials & Fabrics: The Foundation of Every Bag
Material choice defines your bag's look, feel, durability, and price. Here are the most common materials used in modern bag manufacturing:
3.1 Common Base Materials
| Material | Best For | Price Range |
|---|---|---|
| Nylon | Backpacks, duffles, outdoor bags | $$ (mid) |
| Polyester | Backpacks, totes, budget bags | $ (low) |
| Canvas | Tote bags, casual bags, eco-friendly collections | $$ (mid) |
| PU (Polyurethane Leather) | Handbags, vegan collections, light luxury | $$ (mid) |
| Genuine Leather | Premium handbags, briefcases, luxury bags | $$$$ (high) |
| rPET (Recycled Polyester) | Eco-friendly collections, sustainable brands | $$$ (mid-high) |
| Vegan Leather | Cruelty-free brands, ethical collections | $$$ (mid-high) |
3.2 Specialty Materials & Technical Terms
PU Coated Nylon has a thin PU coating on the back of the fabric — water beads off like a lotus leaf, making it ideal for outdoor bags. PU Film Bonded Nylon has a thicker PU layer on the surface, giving it a leather-like look with a stiffer hand-feel (common in light-luxury handbags).
Herringbone Cotton Canvas features a distinctive V-shaped weave pattern — thick, durable, and abrasion-resistant. With a waterproof coating on the back, it works well as a main bag body fabric.
Composite Backing is an extra fabric layer bonded to the back of the face material, making the overall fabric stiffer and more shape-retaining. Single-layer fabric is the opposite — thinner and softer, typically used for linings.
Denier (D) measures fiber density — a higher number means thicker yarn. Common specifications: 210D, 300D, 600D, 900D, 1680D. GSM measures fabric weight per square meter — used for canvas, cotton, and non-woven fabrics.
Cooling Fabric is a nylon-spandex blend (typically 86% nylon + 14% spandex) with a cool touch sensation — commonly used as the inner lining of pet carrier bags. Mesh is a breathable open-weave fabric used for internal pockets and external water bottle holders.
Microfiber Vegan Leather is a synthetic leather with a surface texture that closely resembles genuine leather — more eco-friendly and durable than many standard PU alternatives.
3.3 Color & Finish Terms
Two key terms for color matching: Swatch Card (a sample card showing available colors provided by the fabric supplier) and Pantone Code (the international color numbering system, with TCX for textiles and U for print/coating). If your desired color is not in stock, expect a Dyeing Fee / Color Matching Fee starting at USD $28 per color, with an 80–90% accuracy rate.
4. Hardware & Accessories: The Small Parts That Make the Whole
Hardware is what buyers notice first when they touch a finished bag. The most common components in OEM bag production:
4.1 Zippers & Closures
YKK zippers are the industry standard — recognized globally for consistency and durability. Range uses YKK zippers in our premium bag lines. Other common types include nylon coil zippers (lightweight, for backpacks and luggage), metal zippers (durable, for jeans and leather bags), and waterproof zippers (coated, for outdoor and marine gear). The zipper head / puller is the slider component, available in many finishes. A zipper pull tab is the small tag attached for easy gripping and branding.
4.2 Buckles, Clips & Fasteners
A D-ring is a metal ring sewn onto the bag to attach straps and accessories. A carabiner / climbing hook is a metal clip with a spring-loaded gate — perfect for outdoor and tactical gear. A buckle / quick release buckle clicks together to secure webbing — press the center to release. A strap adjuster adjusts the length of webbing straps. A drawstring buckle tightens drawcord closures on gym bags and hoodies. A magnetic snap provides silent closure for handbags and flap pockets.
4.3 Hardware Finishes & Components
White Nickel is the most common and affordable hardware finish. Matte finish looks more premium but is harder to color-match. Gunmetal finish is dark gray, popular in tactical and men's bags. Die-casting is the manufacturing process that forms buckles, D-rings, and logo plates. Grommets / eyelets reinforce drawstring openings and ventilation holes. Rivets reinforce high-stress points like strap attachments.
5. Production & Process: How Your Bag Is Made
Understanding the production process helps you set realistic timelines and quality expectations.
5.1 Pre-Production
Every custom order starts with a Tech Pack — a comprehensive document specifying every design, material, hardware, color, and dimension. From the tech pack, the factory creates paper patterns — flat paper templates of each bag component. These are used to cut the fabric. Cutting is the process of cutting large rolls of fabric into individual pieces. Expect a wastage / waste allowance of 3–8% — the unavoidable material loss during production.
5.2 Sewing & Stitching
The factory floor uses high-speed sewing machines (the workhorse for thick, multi-layered sections) and computerized sewing machines (programmed for bar tacks and box-X stitches). A bar tack is a dense reinforced stitch at high-stress points like handle bases. A box-X stitch is an X-pattern enclosed in a rectangle, used for maximum load-bearing reinforcement. Overlock / serging wraps raw edges to prevent fraying. A topstitch is a visible decorative and reinforcing stitch on the outside of the bag.
5.3 Assembly, QC & Finishing
After the pre-production sample (PP sample) is approved, production moves to the assembly line flow — the bag moves from station to station, with each worker specializing in one step. Workers are typically paid on a piece rate basis (a fixed amount per completed bag or step). In-line inspection is performed at every stage to catch defects early. AQL (Acceptable Quality Level) defines the maximum acceptable defects per 100 units — common AQL levels for bags are 1.0 (premium), 2.5 (standard), and 4.0 (budget). Edge painting / edge coating seals the raw edges of leather components for a polished, premium look.
6. Business & Order: The Commercial Side of Sourcing
Every OEM order follows a similar commercial flow:
- Quotation / Quote — the factory issues a formal price offer based on the tech pack (typically valid 15–30 days).
- PI (Proforma Invoice) — a preliminary invoice used to arrange the deposit.
- Deposit (Down Payment) — usually 30% of the total value, paid before production starts.
- Lead Time — typically 30–45 days from deposit to ready-to-ship.
- Bulk Production — the full order quantity is manufactured, with in-line QC.
- Final Inspection — comprehensive QC check by the factory or a third party (SGS, BV, QIMA) before shipment.
- Balance Payment — usually 70% by T/T after inspection.
Range's standard MOQ (Minimum Order Quantity) is 100 pieces per color per style for custom OEM orders. We accept T/T (Telegraphic Transfer) as the standard payment method. For Alibaba buyers, we support Trade Assurance for order protection.
7. Product Structure: What Makes a Bag Functional
Inside every well-designed bag, you will find:
- Main Compartment — the largest interior cavity, where the bulk of contents are stored.
- Secondary Compartment / Front Pocket — a smaller front pocket for quick access to keys, wallets, phones.
- Laptop Compartment / Padded Sleeve — a padded section for 13", 15", or 17" laptops. Some sleeves are suspended from the bottom of the bag to protect the device even if the bag is dropped.
- Tablet / iPad Sleeve — a smaller padded section for 9–12 inch tablets.
- Interior Zipper Pocket — a zippered pocket for valuables and passports.
- Open Interior Pocket / Slip Pocket — a non-zippered pocket for quick-access items.
- Pen Holder / Pen Slot — small loops for pens, pencils, and styluses.
- Card Slot / Card Pocket — flat pockets for business cards or credit cards.
- Hidden Pocket / Security Pocket — a discreet pocket on the back (worn against the body) for passports and cash.
- Shoe Compartment — a separate zippered compartment for shoes, keeping them away from clean clothes.
- Wet / Dry Separation Compartment — a waterproof-lined compartment for wet items.
- Toiletry / Wash Bag Pocket — a small interior pocket for wash bags and toiletry kits.
7.1 Exterior Structure & Carry System
The exterior of a bag is just as important as the interior. A top handle / carry handle is the reinforced handle on top of the bag. A shoulder strap carries the bag over the shoulder. A padded shoulder strap has 5–10mm of foam to distribute weight. The back panel / back padding uses mesh and channels to allow air circulation and reduce sweat. A side pocket / water bottle pocket holds a water bottle or umbrella.
8. Trade Terms & Logistics: Shipping from China to the World
Once production is complete, you need to ship the goods. The international rules for shipping are defined by Incoterms® 2020 — a set of trade terms published by the International Chamber of Commerce (ICC).
8.1 The Most Common Incoterms® for Bag Orders
| Term | What the Seller Does | Risk Transfers at |
|---|---|---|
| EXW (Ex Works) | Makes goods available at factory | Factory door |
| FOB (Free On Board) | Loads goods onto vessel at origin port | Origin port (loaded) |
| CIF (Cost, Insurance & Freight) | Pays for cost, insurance, and freight to destination port | Origin port (loaded) |
| DAP (Delivered At Place) | Delivers to buyer's named place (not duties) | Buyer's named place |
| DDP (Delivered Duty Paid) | Delivers to buyer's door, pays all duties | Buyer's door |
Most OEM bag orders from China ship under FOB Shenzhen or FOB Guangzhou (Range's home port). For buyers who prefer a single all-inclusive price, DDP is the most convenient option.
8.2 Customs, HS Code & Documentation
Every international shipment needs an HS Code (Harmonized System Code) — an international classification for traded products. Common HS codes for bags: 4202.12 (travel bags), 4202.22 (handbags with outer surface of plastic or textile), 4202.92 (other bags with textile outer surface). The HS code determines the customs duty / tariff — US import duty on most bags ranges from 5% to 17.6%.
You will also need a Certificate of Origin (CO / COO), a Commercial Invoice, a Packing List, and a Bill of Lading (B/L). The B/L is a legal document issued by the shipping line that serves as a receipt, a contract of carriage, and a document of title.
8.3 Shipping Modes & Containers
For small orders, LCL (Less than Container Load) consolidates your goods with other buyers — cheaper but slower. For large orders, FCL (Full Container Load) gives you an entire container — faster and more secure. Standard container sizes: 20ft (TEU) holds approximately 28 CBM and fits 800–1000 backpacks. 40ft (FEU) holds approximately 58 CBM and fits 1800–2200 backpacks.
Always arrange cargo insurance (0.3%–0.5% of cargo value) — carriers limit their liability by default, and ocean transit involves real risk.

9. Frequently Asked Questions
What is the difference between OEM and ODM?
OEM (Original Equipment Manufacturer) means the factory produces bags according to your design and specifications. ODM (Original Design Manufacturer) means the factory provides the design and you put your brand on it. Range offers both — we can manufacture your exact design or help you develop a new design from scratch.
How do I choose the right material for my bag?
Start with your target market and price point. For mid-market backpacks, nylon or polyester is the most popular. For premium handbags, PU leather or genuine leather is standard. For eco-conscious brands, rPET or canvas works well. For luxury, microfiber vegan leather or top-grain cowhide delivers the premium look and feel.
What is the standard production lead time?
For most custom bags, the typical lead time is 30–45 days from deposit to ready-to-ship. Complex designs with custom hardware or special materials may take longer. Sample development typically takes 7–15 days before bulk production.
Can I visit the factory before placing an order?
Yes — we welcome client visits to our Guangzhou facility. Please contact us in advance to arrange a tour, sample review, and face-to-face meeting with our production team.
What payment methods do you accept?
We accept T/T (Telegraphic Transfer) — typically 30% deposit before production and 70% balance before shipment. For Alibaba orders, we also support Trade Assurance for order protection.
