China‑based Dalian Golden House Door & Window Co., Ltd. lists ten distinct fire‑rated door products in its catalogue. The list includes wooden fire doors, hollow‑metal doors rated for three‑hour fire resistance, and several steel fire doors, with HS‑code families 7308.30 for steel‑based doors and 4418.90‑4418.99 for wood‑core doors.

Product Range and Specialties of Dalian Golden House Door & Window Co., Ltd.

The catalogue features items such as a Wooden Fire Door, UL Listed Wooden Fire Door (HS 4418.99), Intertek Wooden Fire Door (HS 4418.90), Hollow Metal Door 3 Hours (HS 7308.30), and UL Standard Steel Fire Door (HS 7308.30). In the fire‑door market, steel doors are commonly produced from cold‑rolled, galvanized sheets with thicknesses from 1.2 mm to 2.0 mm to achieve 30‑, 60‑, 90‑, or 120‑minute ratings under EN 1634‑1 or UL 10C. Wooden fire doors typically use a solid or engineered wood core with a steel frame, and are graded by fire‑resistance time (e.g., 30 min, 60 min, 90 min) and surface finish. UL‑listed or Intertek‑certified doors indicate third‑party testing to recognized fire‑safety standards, which buyers often compare against local building code requirements.

Trade and Export Information - Dalian Golden House Door & Window Co., Ltd.

Chinese fire‑door exporters usually target construction markets in the Middle East, Southeast Asia, Africa, and parts of Europe where high‑rise and industrial buildings require strict fire‑safety compliance. HS 7308.30 doors are classified under Chapter 73 (articles of iron or steel), while HS 4418.90/4418.99 fall under Chapter 44 (wood products). Buyers typically ask for CE Declaration of Conformity, UL test reports, or equivalent fire‑test certificates, alongside material certificates for steel or wood. Standard export packaging involves wooden doors crated in timber frames or steel doors packed in steel‑reinforced pallets, allowing full‑size 20‑ft or 40‑ft container loads. Common Incoterms are FOB Dalian port or CIF destination port, with customs duties calculated on the HS code value.

Sourcing from Dalian Golden House Door & Window Co., Ltd. - Buyer Guidance

When sourcing fire‑rated doors from this supplier, request the specific fire‑rating test report (e.g., UL 10C, EN 1634‑1) that matches the quoted duration. Verify the material certification for steel (galvanization thickness, cold‑roll grade) or wood (core density, moisture content) and confirm the presence of a CE or UL label on the product documentation. Ask for a product sample or detailed technical drawing to check dimensions, hardware compatibility, and finish before confirming a bulk order. Ensure the supplier can provide a Declaration of Conformity and that the HS code on the commercial invoice matches the product material (7308.30 for steel, 4418.90/4418.99 for wood).

What fire‑rating durations are available for the listed doors?

The catalogue mentions 3‑hour (180‑minute) ratings for hollow‑metal doors and a 90‑minute rating for a wooden fire door. Additional durations such as 30, 60, or 120 minutes are common in the market and can be requested.

Which certifications should I ask the supplier to provide?

Ask for the UL test report for UL‑listed doors, the Intertek report for Intertek‑branded doors, and a CE Declaration of Conformity if the doors are intended for European markets. Material certificates for steel galvanization or wood moisture content are also advisable.

What are the typical material specifications for the steel fire doors?

Steel fire doors under HS 7308.30 are usually made from cold‑rolled, galvanized steel sheets with thickness between 1.2 mm and 2.0 mm, providing the structural strength needed for fire‑resistance ratings up to three hours.

How are the wooden fire doors constructed?

Wooden fire doors listed under HS 4418.90/4418.99 combine a solid or engineered wood core with a steel or metal frame, often with a fire‑resistant seal and surface treatment to meet the specified fire‑rating time.

What is the typical minimum order quantity (MOQ) and lead time?

Chinese fire‑door manufacturers generally set an MOQ of one full door unit per model, with lead times ranging from 25 to 45 days depending on the fire‑rating certification and finish required.

How are the doors packaged for international shipment?

Steel doors are usually crated in reinforced wooden boxes and palletized; wooden doors are similarly crated with protective padding. Both can be loaded into 20‑ft or 40‑ft containers, with weight and volume calculated per HS code.

Which HS codes apply to the different door types?

All steel‑based fire doors in the list use HS 7308.30, while wooden fire doors are classified under HS 4418.90 (solid wood) or HS 4418.99 (wood with steel frame).
