B2B Buyers We Support
Our supply process is built for repeat B2B sourcing, approved specifications and multi-SKU order planning rather than single-piece retail sales.
Fabric Inspection & Cutting
Incoming fabric is checked against the approved order reference for composition, shade, hand feel, width and visible defects as applicable. Cutting follows the confirmed pattern and size set, with panel direction, matching and cut accuracy reviewed before sewing.
Sewing & Waistband Assembly
Sewing methods are selected to match the construction, using industrial sewing, overlock, flatlock and waistband equipment where required. In-line checks cover seam type, skipped stitches, puckering, waistband attachment, elasticity, label position and general workmanship.
In-Line & Finished Product Inspection
Finished-product checks compare key measurements, stitching, seam appearance, waistband condition, color, labels and overall workmanship with the approved reference. Needle detection and final random inspection can be applied before goods are released for packing.
Packing & Export Preparation
Packing is checked against the approved specification, including individual packs, retail boxes, care and size labels, barcodes, assortment ratios and carton marks. Export shipments can be coordinated under EXW, FOB, CIF or DDP terms through Ningbo or Shanghai.
Why Choose Fibrena Underwear
Fibrena Underwear supports repeat sourcing through specification-led development, controlled bulk production and practical export coordination rather than open-ended customization.

A defined approval sequence keeps product specifications, samples, production timing, inspection and shipment responsibilities clear from inquiry to dispatch.
