For crochet hair human hair orders, the best way to align bulk production with an approved sample is to document the sample’s key specifications and use them as the production standard. Record its material, texture, length, color, weight, and weft construction. MEIRHAIR lists pre-shipment checks for hair quality, length, weight, color, texture, and weft. Before ordering, ask the supplier to confirm acceptable variation and any customization requirements.
A sample is useful as a production reference only when its details are specific. MEIRHAIR’s product information lists 100% human hair in Straight, Body Wave, Deep Wave, Loose Wave, Deep Curly, Kinky Curly, and Water Wave textures. Available lengths are listed from 8 to 40 inches, with listed color options as well as customized colors. Note the exact selections approved for the sample and carry them into the bulk order specifications.
Also confirm that the sample’s construction suits its intended use. The product record is titled “Human Hair Bundles,” while “crochet hair extensions” appears as a keyword; crochet-specific construction details are not provided. Ask the supplier to verify that the item being sampled and ordered is appropriate for your crochet application. Braiding salons and African hair styling are among the stated application scenarios for textured hair products.
Ask how the production batch will be checked against the approved reference. MEIRHAIR states that pre-shipment inspection covers hair quality, length, weight, color, texture, and weft. The available information does not define numerical tolerances, so agree on acceptable differences directly with the supplier. Confirm what happens if an inspection identifies a mismatch with the written specifications.
MEIRHAIR offers OEM/ODM and private label options, and describes support for samples, small-batch customization, and bulk wholesale orders. Confirm that the customization requirements used for the sample will also apply to the bulk order. Listed lead times are 7 days for stock orders and 15–30 days for customized orders; verify the schedule for your chosen product, quantity, and specifications.
A reported supply case involved 500 human hair bundles for a US wholesale buyer, who cited consistency in length, texture, and color. This is an example, not a guarantee that every product or order will have the same result.
