Coordinating a large project means every material decision affects cost, schedule, and client satisfaction. As Opaly’s Export Sales Manager, I help procurement teams worldwide source quartz slabs without delays or surprises.

Follow these five steps to secure consistent-quality Opaly slabs, keep lead times predictable, and control your landed cost from factory to site.

Here’s the exact process I recommend to our bulk buyers.

How do you define project requirements before contacting us?

Skipping the requirement phase leads to extra cost and order changes later. I always advise buyers to start here.

Prepare a clear spec sheet covering slab size, thickness, finish, color, quantity, and delivery schedule before the first quotation.

A well-prepared spec sheet lets us align production and packing plans from day one. This is especially important for multi-container orders or phased shipments. It should also include installation drawings if pattern matching is required.

Requirement Item Why It Matters for Opaly Example Value
Size & thickness Determines mold setup 3200×1600 mm, 20 mm
Finish & color code Matches batch QC Polished, OP-102 Snow White
Quantity per phase Aligns production slots 3 containers first phase
Delivery window Matches shipping booking June 10–20
Special notes Reduces rework risk Seamless island joints

How do you get the most accurate quotation?

Inaccurate quotes create budget gaps later. My goal is to give you a firm, transparent cost from the start.

Share your complete project specs, destination port, and any extra processing requirements when requesting the quote.

At Opaly, our quotations include slab unit price, packing cost, and optional freight rates. We also note lead time for both standard and custom colors. For repeat orders, we can lock prices for a defined period to help you control project budgets.

Quotation Detail Benefit to Buyer
CIF & FOB options Lets you choose best logistics plan
Validity period Protects against sudden cost changes
Lead time range Helps align site schedule
QC documentation Confirms compliance early

How do you confirm and secure production slots?

Large orders need clear confirmation to hold production capacity. I always confirm with clients in writing before scheduling.

Place a formal purchase order and arrange the deposit to lock your production slot and delivery date.

Once we confirm, we assign your order a batch code and allocate raw materials immediately. This ensures color consistency and avoids delays due to high-season capacity limits.

Step in Confirmation What Happens at Opaly
PO received Order entered in ERP system
Deposit confirmed Raw materials reserved
Batch code assigned QC reference sample created
Production start First slabs molded within 7 days

How do you manage quality checks before shipment?

QC after loading is too late. We invite clients to review slabs before shipping.

Request pre-shipment inspection with photos, videos, or third-party QC to verify color, finish, and dimensions.

Opaly’s QC process includes 100% visual inspection, thickness and size measurement, gloss level check, and surface defect review. For overseas clients, we share detailed inspection reports before final payment.

QC Check Point Standard Value
Thickness tolerance ±0.5 mm
Color variance ΔE < 0.5
Gloss level ≥ 95 GU
Edge chipping rate < 2%

How do you ensure smooth shipping and delivery?

Shipping is often the most unpredictable part for international buyers. We aim to make it transparent.

Confirm shipping terms, receive container loading photos, and track your shipment in real time.

Conclusion

By defining your specs, securing production slots, and verifying QC before shipment, you can count on Opaly quartz slabs to arrive on time, meet project requirements, and keep costs under control.
