Door Supplier & OEM Buying Guide for Distributors
Prepare a door sourcing request for distributors and projects. Compare specifications and quotations, confirm samples and packing, and discuss OEM branding.
When sourcing a door supplier, define the target market, configuration and acceptance requirements before comparing prices. TEENPAI manufactures entrance and security doors in Yongkang, Zhejiang, China for overseas distributors, contractors and OEM buyers. This guide helps buyers prepare verifiable requirements; it does not replace agreement on a specific order.
Step 1: Build a specification schedule
List each model separately: door type, outside frame dimensions, site opening, wall thickness, handing, material, sheet thickness, overall leaf thickness, finish and locks. Record quantities by size and configuration, plus the destination country and delivery location.
Step 2: Compare suppliers on the same configuration
Align the photographs, specifications, locks, accessories, packing, trade terms and included costs behind each quotation. A price per door is not enough: different dimensions, frames and locks may make quotations incomparable. Confirm omitted requirements in writing.
Step 3: Agree samples, drawings and acceptance
Discuss the sample or drawing approval process and record critical dimensions, handing, lock installation and surface appearance in the confirmation documents. If the project requires certificates or test reports, check the model, configuration and standard covered by the evidence. Do not transfer evidence from an unrelated product.
Step 4: Confirm OEM, packing and shipment
Confirm brand markings, instructions, accessory lists and packing separately. Explain handling and transport conditions to export sales, and discuss full or mixed containers, batches and scheduling. Minimum quantities, production timing, payment and trade terms are order-specific.

Buying questions
What is the minimum information for a quotation request?
Send a model or reference image, sizes and quantities, handing, material and lock requirements, and destination country. Include drawings and acceptance standards when available.
What are the minimum order quantity and production time?
There is no single commitment for every model and configuration. Export sales must confirm these using the designs, size mix, quantities and production schedule.
How do I discuss distributor or OEM cooperation?
Describe your sales market, business type, planned quantities and branding requirements, then discuss the range, samples and quotation with export sales.
