About Us
Clean Beyond Borders — Since Day One.
Nantong Longwhale International Trading Co., Ltd. is a full-range supplier of garment finishing and commercial laundry equipment, serving factories, hotels and hospitals worldwide.
Company Profile
A Full-Range Equipment Supplier Built on Craft.
Based in Nantong, Jiangsu — a strategic port city with world-class logistics — we focus on R&D, quality inspection, global sales and after-sales service. Under the registered brand LONGWHALE, we serve four core markets: garment factories, commercial laundry shops, hotel laundry rooms, and hospital medical washing centers.
We deliver complete equipment solutions rather than single machines, helping global customers realize true one-stop procurement for garment ironing production and linen washing operations.
