For crochet hair human hair bundles, the available product details do not define a standard numerical tolerance for length differences between bundles. The listed 14–30-inch range indicates the lengths customers can order, rather than the amount of variation permitted within a single shipment. Before purchasing, buyers should obtain written confirmation from the supplier about the measurement method and acceptable tolerance, particularly for customized, wholesale, or bulk orders.
The correct length tolerance depends on the specifications of the individual order. Although the product listing provides selectable lengths, it does not state a maximum difference, testing procedure, or formal standard for variation among bundles. As a result, the available information cannot establish how many inches of difference should be regarded as normal.
MEIRHAIR indicates that hair quality, texture, length, color, and weight can be inspected. Buyers should ask how the hair length will be measured, whether it will be measured stretched or in its natural state, and at which stage the inspection will take place. The permitted difference should be agreed upon before production or dispatch.
Customized orders are listed with a production period of approximately 15–30 days, depending on the requested specifications, while stock products are listed at around 7 days. The final order confirmation should clearly record the required length, texture, shade, quantity, and inspection criteria.
These bundles are intended for braiding salons, African hair styling businesses, and other professional applications involving Boho braids and textured protective hairstyles. MEIRHAIR also describes supplying Boho braiding hair to a United Kingdom wholesaler for salon services; however, that case information does not provide a specific length-variation tolerance.

| Item | Currently stated | Buyer should verify |
|---|---|---|

| Permitted variation | No numerical limit provided | The maximum acceptable difference within the order |

Does the 14–30-inch range show how much bundles may differ?
No. It represents the range of lengths available for ordering. It does not mean that bundles in one order can differ by as much as 16 inches.
What amount of length variation is considered normal?
No numerical tolerance is published in the available product information. The supplier should confirm the acceptable difference for the selected length and order quantity.
Which details should be confirmed before ordering?
Confirm the target length, measurement method, allowable tolerance, texture, color, weight, quantity, and inspection procedure. Customized textures are available, and the listing includes length and color inspection.
The 14–30-inch specification describes the product’s selectable length range, not an allowance for variation between bundles. Because no formal tolerance is stated, request written confirmation of the measurement procedure and maximum acceptable difference before approving a sample, small production run, or wholesale shipment.
