What Documentation Verifies the Silicone Grade in an Adhesive Bra?

Before approving an adhesive bra, buyers should verify not only its stated composition but also the identity and traceability of the silicone used. Xinrui describes its V-shaped invisible sticky bra inserts as 95% cotton and 5% silicone. However, the available product details do not name a silicone grade or include a certificate specific to that grade. Request those records and confirm they correspond to the material in the goods being ordered.

Product Details and Key Checks

• The listed composition is 95% cotton and 5% silicone. The inserts are full-cup, measure 11 cm × 11 cm, and are offered in nude or black.
• No silicone grade is specified in the supplied product information. Ask for the grade designation and written confirmation that it applies to the supplied inserts.
• Request traceable documentation linking incoming material checks, production inspections, and finished-product inspections to the relevant order and material batch. Xinrui lists all three inspection stages.
• The inserts are described for backless dresses. Xinrui also identifies bridal wear and evening or party outfits as uses for its invisible intimate apparel range.

Building a Traceable Evidence Package

Composition and material grade are separate pieces of information. The 95% cotton and 5% silicone statement describes the product’s composition, but does not identify the silicone supplier, grade, or grade-specific test results. Ask the supplier to provide the exact grade and records showing that this material was used in the V-shaped inserts for your order.

Next, check whether the material evidence can be followed through the supplier’s quality process. Compare it with incoming raw-material inspection records, in-process production checks, and final-goods inspection results. Xinrui lists these inspection stages in its product information. The company also says it verifies after-sales claims involving shortages or damaged goods for resupply or a price deduction.

The company profile reports ISO 9001, ISO 14001, BSCI, and BRC management-system certifications. It also states that SGS testing is conducted and that RoHS, REACH, MSDS, and ISO 10993 certificates are available. These general company statements do not establish which silicone grade is in this specific product. Ask for the relevant reports and confirm their scope covers the product and material under review.

Xinrui describes itself as a factory-based supplier of invisible underwear and intimate apparel, providing product development, mass production, OEM/ODM services, and packaging customization. Its profile reports a five-person engineering team and four full-time QC inspectors. Samples are listed as available, and the product information gives a custom MOQ of 10 pairs.

Evidence to Request

Frequently Asked Questions

Does the product listing name the silicone grade?

No. It states that the product contains 95% cotton and 5% silicone, but does not identify a specific silicone grade.

Which quality checks does Xinrui list?

The product information 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 listed certificates proof of the silicone grade?

Not by themselves. The company profile mentions management-system certifications and several available test or compliance documents, but buyers should confirm each document’s scope and request evidence specific to the silicone grade.

Recommendation

Before approving the adhesive bra, obtain the silicone grade designation and supporting documentation. Check that the records connect the stated 95% cotton, 5% silicone composition with the ordered product, its material batch, production checks, and finished-goods inspection.
