After reviewing fit feedback, the required lead time depends on whether the adjustment uses an existing lifting bra tape specification or involves developing a new customized product. For sample orders below 100 pieces, revisions based on an existing specification generally require 5 working days. If the feedback calls for a newly customized item, development and production iterations may take 20–50 days.
The first step is to identify the scope of the requested change. If fit feedback only requires an adjustment to an established product specification, the stated sample lead time is 5 working days for quantities below 100 pieces. This timeline is suitable when the product structure, tooling, and materials remain substantially unchanged.
A longer schedule applies when the feedback requires a new customized item. Xinrui indicates that newly customized products may be developed and introduced within 20–50 days. This window can include design confirmation, mold updates, silicone filling, sample production, testing, and additional fit iterations.
Fit-related development may involve changes to dimensions, outline, adhesive performance, color, branding, packaging box, OPP bag, hang tag, or combination sets. Each change can influence the production plan. For example, modifying the lifting shape or overall size may require new tooling, while a change in adhesive strength may require material evaluation and performance checks.
Dongguan Xinrui Underwear Co., Ltd. reports having five R&D engineers and using molding and silicone filling equipment for standardized production. Its quality control workflow includes incoming raw material inspection, checks during manufacturing, and finished-product inspection before shipment.
For bridal and formalwear brands, the company describes plus-size lifting breast pads and invisible coverage products for open-back, deep-V, wedding, reception, evening, and party dresses. These applications often require careful attention to lift, concealment, edge visibility, and adhesive performance.
Swimwear is another listed use case. Xinrui describes waterproof adhesive products for bikinis, split swimsuits, and beach dresses, where the revised sample may need to be assessed for secure wear and suitability in moisture-related conditions.
The company reports a monthly capacity of 1.5 million pieces and combines manufacturing with trading services. After shipment, its stated support process provides replacement for verified shortages or damaged products, or a corresponding payment deduction through a price discount.
Listed certifications and credentials include BSCI, ISO 9001, RoHS, REACH, BRC, and ISO 10993. One reported cooperation case involves a long-term relationship with a US-based online women’s apparel seller that uses nipple covers for formalwear, yoga, and bridal accessory categories.
| Project type | Stated lead time | When it applies |
|---|---|---|
| Revision using an existing specification | 5 working days for orders under 100 pieces | Fit feedback can be applied without creating a new product structure |
| Small sample or limited order | 7 working days for 100–1,000 pieces | Defined requirements are used for sample or small-batch production |
| New customized item | 20–50 days | New size, shape, adhesive specification, molding, or related development is required |
| Mass customization | 15 working days for 1,000–5,000 pieces, depending on customization | Production begins after the revised specifications have been approved |
Plan for 5 working days when the sample order is below 100 pieces and the revision remains within an existing specification. Allow 20–50 days if fit feedback results in a newly customized product.
Potential options include size, shape, adhesive strength, color, logo, packaging, and set combination. The available choices depend on the product design and confirmed manufacturing requirements.
The stated quality system includes inspection of incoming raw materials, monitoring during production, and inspection of finished goods. The company also lists BSCI, ISO 9001, RoHS, REACH, BRC, and ISO 10993 credentials.
For a revised lifting bra tape sample under 100 pieces, use 5 working days as the baseline when the existing product specification remains unchanged. When the requested fit improvement affects molding, dimensions, shape, adhesive strength, or another core feature, plan for a 20–50-day development cycle.
