Frequently Asked Questions

While we strive to address the crucial questions you may have, we cannot predict every situation. WD people love communication, so feel free to drop us a message anytime.

How many samples can I order?

If you want to purchase directly from our online store, the shipment cost is calculated based on freight shipment, which is more expensive compared to sea shipment. We suggest purchasing 3-10 products directly from our online shop. If you need more samples to test the stability of our products, we recommend filling out the form through the "B2B Quotation" button or on our contact page. We will assess your eligibility for free sample quantities and offer a negotiable shipment solution to lower your costs.

What is the minimum order I can place?

For WD136 and WD166 in cartridge packaging, you can order as few as 1 box for black and white colors, but for colored ones, the minimum order is 80 boxes. WD188 and WDGP in Cartridge packaging are common products with fixed colors. WD188 is only available in transparent, while WDGP comes in black, white, and transparent, so there's no minimum order requirement.As for the sausage packaging WD838, WD866, WD886, and WD986, you can order just 1 piece for black, but for white and colored ones, you need to order at least 10 boxes. For the two-component Silicone Sealant in metal barrel and plastic barrel WD981, WD861, and WD831, the minimum order quantity is 1 set.For clarity, each cartridge box contains 24 units, so if you need 80 boxes, you'll get 1920 units. Each sausage box contains 20 pieces, totaling 200 pieces per box, so if you need 20 boxes, you'll get 4000 pieces.

Can I get a cheaper price?

WD Sealant offers competitive pricing that aligns with our high-quality products. If you're seeking a better deal, it's important to understand our pricing structure: The unit price for a full container is discounted for two primary reasons. Firstly, there's a discount applied to the unit price, albeit essentially a surcharge on the loose cargo unit price. Secondly, lower shipping costs contribute to this discount. So, while we aim to offer fair prices, the best value is often found with full container orders.
