Bulk hair extensions

In the B2B market, hair is generally categorized by its source and processing. Virgin Hair is the highest quality, chemically unprocessed and sourced from a single donor with cuticles intact. Remy Hair ensures all cuticles run in the same direction to prevent tangling. For bulk orders, you must verify the 'Drawing' process: Single Drawn contains varying lengths (mimicking natural growth), while Double Drawn is manually sorted to ensure uniform thickness from root to tip, which commands a higher price point but offers superior volume.

Buyers should focus on Gram Weight per Bundle (typically 100g) and Ratio of Longest Hairs. Ensure the Cuticle Integrity is verified through a 'rub test' to check for smoothness. For pre-bonded extensions (like I-tip or U-tip), the Keratin Quality is critical; high-quality Italian Keratin is preferred as it prevents shedding and is resistant to heat and chemicals. Additionally, confirm the Color Fastness to ensure the hair does not bleed during washing.

While hair is a natural product, the processing chemicals must meet safety standards. Ensure the supplier complies with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the dyes and silicones used. For the US market, products should be free from harmful levels of Formaldehyde. It is highly recommended to source from suppliers with ISO 9001 certification to ensure consistent batch quality and SGS or Intertek inspection reports for hygiene and sterilization.

Request a sample to perform a Bleach and Dye Test; high-quality human hair should be able to reach Level 613 (Platinum Blonde) without significant degradation. Check the Heat Resistance by applying a styling iron at 180°C; synthetic blends will melt or smell like plastic. For long-term performance, the hair should maintain its Elasticity and Luster after at least 20-30 washes.

The most prevalent risk is Material Substitution, where suppliers mix human hair with synthetic fibers or animal hair (like yak) to reduce costs. Another risk is Weight Discrepancy, where the net weight of the hair is less than advertised due to heavy packaging or rubber bands. To mitigate this, use Made-in-China.com's Secured Trading services and insist on a Third-Party Pre-shipment Inspection to verify the material composition and weight.

Hair prices are volatile based on raw material costs. Negotiate based on Volume Tiers; for example, a 5-10% discount for orders over 5kg. Instead of focusing solely on the unit price, negotiate for Value-Added Services such as custom branding, specialized packaging, or Private Labeling. For new styles, request a Low MOQ for Trial Orders (e.g., 1kg mixed lengths) to test market response before committing to large-scale inventory.

Hair products are often subject to Quarantine Inspections in certain countries. Ensure the supplier provides a Fumigation Certificate and a Certificate of Origin to facilitate smooth customs clearance. When shipping to the US or EU, clearly label the goods as '100% Human Hair' to avoid misclassification. For high-value bulk shipments, Air Freight (DHL/FedEx/UPS) is the industry standard due to the high value-to-weight ratio and the need for fast inventory turnover.

Always verify the supplier's Business License and Factory Location. Use the Audit Reports available on Made-in-China.com to check the supplier's production capacity and gold status. Avoid direct wire transfers to personal accounts; instead, use Escrow-based payment systems where funds are only released upon confirmation of receipt and quality. Document all specifications in a Sales Contract to provide a basis for dispute resolution if the quality deviates from the approved sample.
