Buyer answer · Water-soluble PVA materials
How much does 40S PVA water-soluble yarn cost per kilogram?
Direct answer
A ‘40S’ label is not enough to price PVA yarn. State the count system, construction, dissolution grade, finish, volume, packing and delivery term, then request a dated quotation with currency, destination and validity stated.
‘40S’ is not enough information to price a kilogram
A supplier cannot make a comparable per-kilogram offer from ‘40S’ alone. The count system, single or plied construction, tolerance, finish and dissolution grade all affect what is being quoted. State whether 40S is the target count of the finished yarn or one component of a plied yarn, and give the unit system used in your specification. If the count convention is ambiguous, ask the supplier to repeat it in writing before discussing price.
A water-soluble yarn quotation also needs its performance basis: the intended process, the required pre-removal resistance, and the removal conditions and endpoint. A price for a standard stock item is not automatically a quote for a custom finish, package or verified grade. Request a dated price with currency, quantity, package, destination, delivery term and validity period stated, so procurement can compare it with a like-for-like offer.
Build one commercial basis for every supplier
| Quote field | Specify | Avoid |
|---|---|---|
| Yarn | Count convention, tolerance, single or plied structure, twist and finish | A bare ‘40S’ label. |
| Grade | Removal target and process acceptance criteria | Treating temperature wording as a full test method. |
| Quantity and pack | Sample, order amount, package format and whether quoted weight is net | Comparing price per cone with price per net kilogram. |
| Delivery | Currency, named destination, Incoterm and quote validity | Comparing different delivery points as if identical. |
If the buyer can accept a standard construction, ask for that quote separately from a custom version. If you need a sample first, ask whether the price refers to existing stock or the exact grade that would be produced for the order. This helps separate a product-selection question from the later question of how much the approved configuration costs.
Compare the delivered cost after the sample passes
Approve technical suitability before ranking unit prices. Once a sample passes the agreed machine and removal trial, compare what it costs to receive and use the yarn: freight, duty, testing, package handling and any buyer-side winding or changeover. Use your own process data for the cost of breaks or downtime. When those costs are not yet known, show them as an open scenario rather than converting an assumption into a supplier saving.
A practical purchase sheet should keep the price per net kilogram, package count, gross shipment weight and expected usable quantity in separate columns. This makes a difference caused by package or weight basis visible. It also prevents a lower headline price from winning when the buyer is actually comparing different yarn constructions or delivery responsibilities.
For the delivery-cost split, consult the ICC's Incoterms rules overview and ask each supplier to use the same named place.
Request the quotation for one exact build
Send the supplier the count system and tolerance, construction, grade, finish, package, sample amount, expected order quantity and destination. Ask for a quote that identifies the price unit, net-weight basis, currency and validity. If the supplier cannot quote without further details, resolve those questions before comparing rather than filling the gaps with assumptions.
The most useful next step is to ask each candidate for a sample and a dated quote against the same specification. That will produce a price you can evaluate after confirming the yarn, rather than a per-kilogram number for an undefined ‘40S’ product.
