Sanitary materials

For non-woven fabrics (spunbond or meltblown), you must verify the GSM (grams per square meter) to ensure the right balance of softness and strength. For Super Absorbent Polymer (SAP), the absorption rate and retention capacity under pressure are critical benchmarks. Ensure that hydrophilic treatments are applied to top sheets for rapid fluid acquisition, while hydrophobic properties are maintained for backsheets to prevent leakage.

Suppliers must adhere to ISO 9001 for quality management and ISO 13485 if the materials are intended for medical-grade use. For consumer goods like diapers or sanitary napkins, products should meet CE (EN 14682) standards for the European market and FDA registration for the U.S. market. Additionally, OEKO-TEX® Standard 100 certification is highly recommended to ensure the materials are free from harmful substances and safe for skin contact.

Request a Certificate of Analysis (COA) for every batch. Conduct microbiological testing to ensure the materials are sterile and free from pathogens. It is also vital to perform skin sensitization and irritation tests (ISO 10993-10) to guarantee user safety. For bulk orders, hiring a third-party inspection agency to perform a random pull-test for tensile strength and elongation is a standard industry safeguard.

Cost-efficiency is driven by material yield and waste reduction. Evaluate the width consistency of fabric rolls to minimize trim loss during high-speed production. Negotiate pricing based on annual volume commitments rather than spot buys, as raw material prices (like polypropylene) fluctuate with oil markets. Sourcing from integrated manufacturers on Made-in-China.com who produce both the raw fiber and the finished non-woven fabric can often reduce costs by 10-15%.

The biggest risk is moisture damage and contamination during sea transit. Ensure the supplier uses heavy-duty moisture-proof PE packaging and vacuum sealing for SAP. To mitigate transaction risks, utilize Secure Payment services on platforms like Made-in-China.com to ensure funds are only released after the bill of lading is verified.

Sanitary materials are high-volume but relatively low-weight, making freight cubing a challenge. Negotiate for FOB (Free On Board) terms to maintain control over shipping lines and ensure the use of High Cube (HC) containers to maximize space. Typical lead times for customized non-woven prints are 20-30 days; always include a penalty clause for delays exceeding 7 days in the purchase contract.

Check the specific HS Codes (e.g., 5603 for non-wovens) to determine if there are anti-dumping duties or specific trade barriers between China and your country. Ensure the supplier provides a complete Packing List, Commercial Invoice, and Certificate of Origin to facilitate smooth customs clearance and potentially benefit from Preferential Trade Agreements.
