Cabin bag

Standard dimensions for most international airlines are 55cm x 40cm x 20cm, but you must verify if the supplier can manufacture to IATA guidelines. Ensure the bag's tare weight is minimized—ideally under 2.5kg for hardshell and under 2.0kg for softshell—to maximize the buyer's usable weight allowance under strict 7kg-10kg airline limits.

For hardshell bags, 100% Virgin Polycarbonate (PC) is the premium choice for impact resistance, while ABS+PC films offer a cost-effective middle ground. For softshell, 1680D Ballistic Nylon or High-Density Polyester with TPU coating provides superior water resistance and tear strength. Avoid cheap recycled ABS as it is prone to cracking under low temperatures in cargo holds.

Prioritize 360-degree dual-spinner wheels with TPE rubber coating for silent movement and durability. Ensure zippers are YKK or equivalent RC (Rack Coil) zippers to prevent bursting under pressure. The telescopic handle should be made of high-grade aluminum alloy with minimal 'wobble' (less than 10mm lateral movement) to ensure structural integrity.

For the US market, TSA-approved integrated locks are mandatory for security inspections. For the EU, materials must comply with REACH regulations regarding phthalates and hazardous chemicals. Additionally, look for suppliers with ISO 9001 certification and products that have passed BSCI (Business Social Compliance Initiative) audits to ensure ethical manufacturing.

Always request a Pre-Shipment Inspection (PSI) by a third party. Specifically, demand a 'Drop Test' (from 90cm height) and a 'Treadmill Test' (wheels running for 20km-30km). Using Made-in-China.com's Secured Trading services can help ensure that payment is only released once the quality report meets your specifications.

Negotiate based on Total Cost of Ownership (TCO) rather than just unit price. Ask for 1-3% spare parts (wheels, handles, and zipper pulls) to be included in the shipment for after-sales support. For orders exceeding 1,000 units, aim for a 15-20% discount compared to the sample price, and push for FOB (Free On Board) terms to maintain control over your shipping costs.

Luggage is a 'volumetric weight' product. To optimize shipping costs, use the 'nesting' method, where smaller bags (e.g., 20-inch) are packed inside larger suitcases (24 or 28-inch) to reduce total CBM. Ensure the outer cartons are 5-layer corrugated fiberboard to prevent crushing during sea freight stacking.

Verify the supplier's Business License and Export Qualification on Made-in-China.com. If you are sourcing a custom design, sign a Non-Disclosure Agreement (NDA) before sharing technical drawings. Use Escrow-based payment methods to protect your capital against non-delivery or significant discrepancies in product specifications.
