What Documentation Verifies the Silicone Grade in This Adhesive Bra?

To verify the silicone used in Xinrui’s V-shaped adhesive bra inserts, buyers need documents that identify the material grade and connect it to the product batch they are purchasing. The listing gives a composition of 95% cotton and 5% silicone, but it does not name the silicone grade or include a certificate specific to that grade. Request those details before approving the material.

Product Details and Evidence Gaps

The listed inserts have a full-cup, V-shaped design and measure 11 cm × 11 cm. They are offered in nude and black and are described as suitable for backless dresses. The broader invisible intimate apparel range is also presented for bridal wear and evening or party outfits.

Composition alone does not establish the type or grade of silicone used. Ask the supplier to provide the exact grade designation, identify the material source, and confirm that the documented material is the one used in the ordered inserts.

Records to Request

A useful review should follow the material through the production process. Xinrui lists incoming raw material checks, in-process production inspection, and finished-goods inspection. Request records for each stage that identify the relevant material batch, product configuration, and order, so you can compare the paperwork with the goods supplied.

The company profile also refers to SGS testing and lists RoHS, REACH, MSDS, and ISO 10993 documents as available. It reports ISO 9001, ISO 14001, BSCI, and BRC management-system certifications. These statements do not independently verify the silicone grade in this specific product. Confirm which reports apply to the bra inserts, what material they cover, and whether they state the grade.

Evidence Checklist

Supplier and Ordering Information

Dongguan Xinrui Underwear Co., Ltd. describes itself as a factory-based manufacturer of invisible underwear and intimate apparel, providing product development, mass production, OEM/ODM services, and packaging customization. Its company profile reports a five-person engineering team and four full-time QC inspectors. Samples are available, and the listing states a custom minimum order quantity of 10 pairs.

The supplier also says that claims involving short shipments or damaged goods are checked, with resupply or a price deduction offered where applicable. For material approval, however, buyers should rely on product-specific documents and batch-linked quality records.

Frequently Asked Questions

Does the listing state the silicone grade?

No. It specifies 95% cotton and 5% silicone, but provides no grade designation.

What quality inspections are mentioned?

The listing names incoming raw material inspection, in-process production inspection, and finished-goods inspection. Ask for records tied to your order and the relevant material batch.

Are the company’s listed certificates enough to verify the silicone?

Not by themselves. Company-level certifications and general test documents do not prove which silicone grade was used in these inserts. Confirm the scope of each report and request grade-specific evidence.

Recommendation

Before approving the adhesive bra, obtain the silicone grade designation and supporting documents, then check that they match the 95% cotton, 5% silicone product specification and the supplier’s material, production, and finished-goods records. Xinrui lists OEM/ODM options and a 10-pair custom MOQ. Contact judy@xinruibra.com to request technical documentation.
