What Documents Verify the Silicone Grade in This Adhesive Bra?

Before approving Xinrui’s V-shaped adhesive bra inserts, buyers should confirm not only the stated fabric composition but also the exact silicone grade and its link to the finished goods. The product listing gives a composition of 95% cotton and 5% silicone, yet does not name a grade or include a grade-specific certificate. That information should be requested from the supplier.

Key Points for Buyers

• The listed inserts have a full-cup, V-shaped design, measure 11 cm × 11 cm, and are available in nude or black.
• The product information identifies silicone as a component but does not specify its grade. Ask for the grade designation and confirmation that it applies to the material used in your order.
• Request order- and batch-linked records for incoming material, production, and finished-goods inspections—the three quality stages listed by Xinrui.
• The inserts are described for backless dresses. Xinrui also lists bridal, evening, and party outfits as applications for its invisible intimate apparel range.

How to Review the Evidence

Confirm the material identity

Composition and grade are different pieces of information. While the product specification states “95% cotton, 5% silicone,” it does not identify the silicone supplier, grade, or a test result tied to that grade. Ask Xinrui to provide the precise grade and documentation demonstrating that the identified material was used in the V-shaped inserts supplied against your order.

Connect records to the order

Check whether the material documents correspond with the relevant incoming raw-material inspection, in-process production inspection, and finished-goods inspection records. Xinrui lists these three inspection stages in its product information. The company also says that claims involving short shipments or damaged goods are verified for resupply or a price deduction.

Check certificate scope

Xinrui’s company profile reports ISO 9001, ISO 14001, BSCI, and BRC management-system certifications. It also states that products pass SGS testing and that RoHS, REACH, MSDS, and ISO 10993 certificates are available. These company-level statements do not establish the silicone grade in this particular product. Request the relevant reports and confirm that their stated material and product scope matches your order.

Xinrui describes itself as a factory-based supplier of invisible underwear and intimate apparel, with product development, mass production, OEM/ODM, and packaging customization. Its profile reports a five-engineer R&D team and four full-time QC inspectors. The listing allows samples and states a custom minimum order quantity of 10 pairs.

Evidence Checklist

Frequently Asked Questions

Is a silicone grade given in the product listing?

No. The listing specifies 95% cotton and 5% silicone, but does not name a silicone grade.

Which quality checks does Xinrui list?

The listed stages are incoming raw-material inspection, in-process production inspection, and finished-goods inspection. Ask for records connecting each stage to your order.

Do the available certificates confirm the grade?

Not based on the information provided. The company profile names management-system certifications and available product test certificates, but buyers should verify the scope and request material evidence specific to the silicone grade.
