Buying engineered oak flooring starts with a complete specification. Before requesting a quote, identify the board dimensions, oak face thickness, core construction, grade, finish, joint profile, and packaging requirements. A color name or grade label alone does not define the product you will receive.
For importers and wholesalers, the aim is to turn a collection sample into an order that both parties understand. This guide uses SONGLINFLOOR’s OEM oak range to explain the questions worth resolving, including the difference between 14/3 mm and 15/4 mm specifications.
1. Read Engineered Oak Flooring Dimensions in Full
The two listed formats are 1900 × 190 × 14/3 mm and 1900 × 190 × 15/4 mm. The first two measurements describe length and width. The final pair identifies total board thickness and oak face thickness.
| Specification | Length × Width | Total Thickness | Oak Face Thickness |
|---|---|---|---|
| 14/3 mm option | 1900 × 190 mm | 14 mm | 3 mm |
| 15/4 mm option | 1900 × 190 mm | 15 mm | 4 mm |
Choose between them by checking the thickness required for your purchasing brief and the oak face specification you intend to offer. Record both measurements: “14 mm flooring” leaves the face thickness unspecified.
A thicker face is a measurable specification difference. It should not automatically become a claim about service life, refinishing frequency, or suitability for a particular installation. Those conclusions require separate support.
Also clarify whether the quoted length describes the requested board format and ask the supplier to confirm the length composition of the actual order. Do not assume a full-length percentage that has not been agreed.
2. Specify the Core and Joint as Separate Choices
The range lists four construction options:
- Three-layer poplar.
- Multilayer poplar.
- Multilayer eucalyptus.
- Multilayer all-birch.
These are alternatives, not four materials used simultaneously in every board. Identify the construction required for the quote and ask for its corresponding specification. Do not assume every thickness, core, joint, and finish combination is available without order confirmation.
Tongue-and-groove and locking profiles are also order-specific choices. Include the required profile in the inquiry rather than leaving it to a general product description.
A joint name does not establish an installation method or underfloor heating suitability. Those application details are outside the confirmed information for this range and should be checked separately when relevant to your market.
3. Confirm Oak Identity and Grade Through Written References
The oak raw material comes from the Changbai Mountain range in Northeast China. The supplied information describes this Chinese oak as White Oak. This does not mean American White Oak, U.S. origin, or U.S. manufacture. Raw material source and finished-board manufacturing location are separate facts.
For grades, the current selections are ABC and CD. Within this series, Premium corresponds to ABC. It should not be treated as equivalent to another supplier’s Select designation.
Character describes a natural-feature direction and may encompass different letter grades, including CC, CD, or DD in different grading descriptions. It is not a fixed synonym for CD, nor does that terminology establish that this range supplies CC or DD.
For purchasing, request the criteria applying to the exact selection. If your requirements concern knots, cracks, filling, grain, or color variation, discuss them explicitly and obtain written agreement. Do not invent numerical limits or interpret ABC as a knot-free guarantee.
Use representative physical samples alongside the written criteria. Keep ABC and CD photographs clearly separated so the images supporting an order match the agreed grade.
4. Approve Color and Finish Together
The six listed colors are Pearl Beige, Warm Wheat, Linen Beige, Stone Greige, Mist Grey, and Natural Sand. Use these names to identify the intended selection, then confirm it against a physical sample.
Color names describe appearance. They do not establish bleaching, smoking, brushing, or an unfinished surface.
The finish options are UV Oiled and UV Lacquered. The supplied range information identifies UV Lacquered as the main direction for the U.S. market, but the actual finish remains an order choice. Confirm it alongside the color and grade rather than assuming it from a photograph.
OEM color customization is supported, with sample development taking approximately two weeks. Confirm the sample specification, charges, and transportation arrangements separately. Retain a clear reference to the accepted version, especially if several revisions have been discussed.
For replenishment, identify the previous order and approved sample. Agree the new order requirements while allowing for natural wood variation; sample approval is not a promise of completely identical batches.
5. Include Packaging in the Inquiry
Packaging belongs in the quotation request even when no packing configuration has yet been confirmed. Ask for the proposed arrangement instead of inserting an assumed carton quantity.
Useful questions include the number of boards and area per carton, carton dimensions and weight, pallet arrangement, and identification labels. If your receiving process requires product, color, grade, or order references on labels, state those requirements for discussion.
These are inquiry items, not confirmed packaging features of the range. Request a written packing specification before relying on it for receiving or transportation planning.
A complete inquiry can follow this checklist.
| Item | Information to Submit or Request |
|---|---|
| Product selection | Color and ABC or CD grade |
| Dimensions | 1900 × 190 mm; 14/3 mm or 15/4 mm |
| Construction | Selected core, with the proposed configuration confirmed |
| Joint | Tongue-and-groove or locking profile |
| Finish | UV Oiled or UV Lacquered |
| Grade reference | Written criteria and approved sample |
| Color approval | Existing selection or OEM target; accepted sample reference |
| Quantity | Required quantity and request for the applicable MOQ |
| Packaging | Boards and area per carton, dimensions, weight, pallet arrangement, and labels |
| Documents | Market-specific documents required for review and confirmation |
| Schedule | Sample development, deposit trigger, production, and separate shipping arrangements |
6. Separate Production Timing from Arrival Planning
The moisture content control target is 7–9%. Treat this as a stated control target, not a guarantee covering every future storage or application condition.
Production lead time starts from 45 days after receipt of deposit, with the specific schedule confirmed for each order. This is not a port-arrival date. Sample review, any revisions, and transportation should be identified separately in the purchasing plan.
SONGLINFLOOR provides weekly order follow-up and supports inspection reports and factory audit arrangements. Clarify the information and arrangements needed for your order. This support should not be presented as proof of factory ownership or unconfirmed certification coverage.
Frequently Asked Questions
1. What is the difference between 14/3 and 15/4 mm?
They indicate total thickness and oak face thickness: 14 mm with a 3 mm face, or 15 mm with a 4 mm face. Both listed formats measure 1900 × 190 mm.
2. Is Premium ABC the same as Select?
Not automatically. Premium identifies ABC within this series. Compare suppliers using their written criteria and approved samples rather than grade names alone.
3. Does Character always mean CD?
No. Character is a descriptive term that may cover different letter grades. The current range lists ABC and CD; the broader terminology does not confirm other grades as available products.
4. Can I order unfinished flooring?
Unfinished supply is not confirmed in the listed range. The stated finish options are UV Oiled and UV Lacquered.
5. Does the production period include shipping?
No. Production starts from 45 days after receipt of deposit, subject to order confirmation. Shipping and arrival timing require separate confirmation.
Submit Your Purchasing Specification
Send SONGLINFLOOR your company name, sales market, required quantity, color, grade, and preferred thickness. Add your core, joint, finish, packaging, and document requirements.
For repeat purchases, include the previous order and approved sample references. Request the relevant product specifications and sample information so the proposed configuration can be reviewed before order confirmation.
