A trolley case line succeeds on size structure. Buyers who map cabin, mid-size and checked sizes before sampling avoid overlapping styles, cover every travel scenario on one shelf and keep tooling costs predictable. Wellmax Luggage, an OEM luggage manufacturer founded in 2013 in Fujian, China, builds trolley cases in ABS, polycarbonate and aluminum-frame constructions, and the current range runs from a 20-inch cabin spinner to a 28-inch checked case.
Wellmax Luggage operates a 12,000 m² facility in Quanzhou, Fujian, with about 320 employees producing roughly 150,000 pieces per month. The factory holds ISO 9001:2015 certification and has been audited under the BSCI framework, and the export team supports buyers in more than 40 countries. The sections below sort the current trolley case range into three size bands and explain the decisions shaping each band.
20 to 22 Inches: The Cabin Segment
Cabin sizes carry the highest unit volume in most OEM luggage programs. The Lightweight ABS Cabin Trolley 20" anchors the band with a lightweight ABS shell sized to fit most airline cabin limits, four spinner wheels and a telescopic handle. ABS keeps tooling and unit cost low, which makes the 20-inch shell a common first mold for private-label programs entering travel retail.
Two more styles round out the cabin band. The Polycarbonate Cabin Luggage 22" pairs an impact-resistant polycarbonate shell with a TSA lock and ships in charcoal, black and navy. The Cartoon Dopamine Spinner Luggage 20" answers the kids and family segment with a bright cartoon colorway on a lightweight ABS shell. All three cabin styles run at an MOQ of 300 pieces with a 30-35 day lead time, so one sampling cycle can test three price points.
24 to 26 Inches: Mid-Size and Expandable Checked Luggage
The mid band serves travelers who check a bag on most trips. The Solid Color Spinner Luggage 24" offers a clean polycarbonate shell in black, navy and red, a shell surface ready for private-label colorways without new tooling, while the Softside Spinner Luggage 24" uses a flexible polyester shell with four double spinner wheels for buyers targeting a softer price point. Both styles share the 300-piece MOQ of the cabin band.
At the top of the band, the Expandable Checked Luggage 26" adds an expandable zipper panel to an impact-resistant polycarbonate shell, and the style ships in black, charcoal and navy. Expandability is a feature retail staff can demonstrate on the sales floor, and the Business Hardshell Trolley 26" gives the same checked size a brushed metal corner finish for corporate channels. Together, the 24-inch and 26-inch styles cover two price steps without overlapping shelf space.
28 Inches and Premium Constructions
The 28-inch segment answers family packing and long trips. The Hardshell Trolley Case 28" PC Spinner offers approximately 95 liters of capacity in impact-resistant polycarbonate, with four double spinner wheels and a textured shell surface designed to help conceal minor scuffs. Matte black, navy and silver colorways position the style for travel retail and corporate programs alike, and the 300-piece MOQ matches the rest of the hardshell line.
Buyers building a premium tier can step up to the Aluminum Frame Checked Luggage Set, a two-piece medium and large configuration with a rigid aluminum frame, reinforced metal corners and an integrated frame lock in silver, gunmetal or black. The set runs at an MOQ of 200 sets with a 35-40 day lead time, so one SKU family covers short and long trips in premium retail.
Material and Feature Decisions Across the Size Range
Material choice tracks price point more than size. ABS keeps cabin trolleys economical, polycarbonate adds impact resistance through the mid and checked bands, and aluminum frames serve the premium tier. Wheels, telescopic handles and zipper grades are the features retail buyers test first, and Wellmax Luggage confirms wheel, handle and zipper specifications per line before sampling so the approved sample matches the target price.
Across the nine styles in the current travel luggage range, the MOQ is 300 pieces per style and the standard lead time is 30-35 days after sample approval, except the aluminum-frame set at 200 sets and 35-40 days. Buyers can review the complete travel luggage range to compare trolley case constructions side by side before selecting styles for a first order.
Frequently Asked Questions
How many sizes should a first trolley case program include?
Three styles across two size bands cover most launches: a 20-inch cabin spinner, one 24 or 26-inch checked case and one premium style. The mix keeps one mold per band and lets early retail feedback decide where the OEM luggage line extends next.
Can one factory produce cabin and checked sizes together?
Yes, when the factory runs hard-goods production in one facility. Wellmax Luggage molds shells, assembles trolleys and inspects finished cases in the same 12,000 m² Fujian facility, so a mixed size order ships under one inspection standard and one set of shipping documents.
Next Step for Buyers
Buyers planning a trolley case line can send target sizes, price points and quantities in one inquiry. The Wellmax Luggage export team returns per-line MOQ, unit price bands and a sampling schedule covering the complete OEM luggage size range, keeping the first order and the retail launch date on one written plan.
