About Yongxing Industial Limited Company - Door Closer/Opener Supplier in China

Yongxing Industial Limited Company operates from China and currently offers eight distinct products in its catalogue. The portfolio focuses on door‑hardware components such as sealing profiles, weather strips, PVC and EPDM seals, rubber seals, triple‑seal door sweeps, bottom door seal brush strips, door sweeps (HS code 8302.41) and extruded rubber. All items are listed under the door‑hardware and raw‑rubber categories, reflecting the supplier’s emphasis on sealing solutions for doors and related applications.

The listed door sweeps are classified under HS chapter 83, heading 8302.41, which covers metal doors, windows and their fittings of base metal. The remaining products fall under HS chapters 39 (plastics) and 40 (rubber) according to material composition. No specific certifications are mentioned, so buyers should request compliance documentation during the sourcing process.

Product Range and Specialties of Yongxing Industial Limited Company

The catalogue includes sealing profiles, weather strips, PVC and EPDM seals, rubber seals, triple‑seal door sweeps, bottom door seal brush strips, door sweeps (PVC with adhesive backing, HS 8302.41) and extruded rubber. In the door‑seal market, PVC seals are commonly produced to GB/T 10002‑2006 specifications, with thicknesses from 0.5 mm to 3 mm and Shore A hardness between 70 and 80. EPDM seals are valued for ozone and heat resistance and are often supplied in grades meeting ISO 1629 standards, typically 60‑80 Shore A.

Raw rubber and extruded rubber products are usually based on natural rubber (NR) or synthetic blends such as SBR, with tensile strength in the range of 15‑25 MPa and elongation at break above 400 %. Door sweeps and brush strips are frequently packaged in bundles of 100‑200 units, with overall lengths of 300‑600 mm to suit standard door widths. Buyers often request material data sheets that detail hardness, tensile strength, aging resistance and fire‑rating where applicable.

Trade and Export Information - Yongxing Industial Limited Company

China is a major exporter of door‑hardware and rubber sealing products, supplying construction and automotive sectors in Southeast Asia, Europe and North America. HS 8302.41 door sweeps are typically shipped in 20‑ft containers, packed in corrugated boxes with moisture‑resistant liners. Commonly required certifications for these categories include ISO 9001 quality management, REACH registration for chemical safety, and CE marking for products entering the EU market. Export shipments from Chinese ports such as Shanghai or Shenzhen often use FOB terms, with buyers arranging CIF or DDP logistics for final delivery.

Typical importers include building‑material distributors, HVAC contractors and vehicle‑interior manufacturers who look for weather‑resistant seals that meet fire‑safety standards such as UL 10B or EN 13501‑1. Inspection regimes frequently involve pre‑shipment sampling, container seal verification and compliance checks against the declared HS codes.

Sourcing from Yongxing Industial Limited Company - Buyer Guidance

When sourcing from this supplier, request a material safety data sheet (MSDS) and a product test report that covers Shore A hardness, tensile strength, elongation and any fire‑rating results. Verify that the PVC seals comply with REACH and that any rubber components meet ISO 1629 composition standards. Samples of the sealing profile or door sweep should be examined for dimensional tolerances (±0.2 mm) and adhesive backing quality before confirming bulk orders.

Confirm the HS code declared for each item matches the material composition; for example, PVC‑based door sweeps should align with HS 8302.41 while pure rubber products fall under HS 4001‑4009. Typical minimum order quantities range from 500 units for brush strips to 2,000 units for extruded rubber sheets, with lead times of 25‑40 days from order confirmation, subject to material availability.

The door sweeps are made of PVC (Polyvinyl Chloride) with an adhesive backing, and they are classified under HS code 8302.41.

Which HS codes apply to the supplier’s product range?

Products with PVC components, such as the door sweeps, use HS 8302.41. Sealing profiles, weather strips and rubber‑based items are generally covered by HS chapters 39 (plastics) and 40 (rubber) depending on the exact material.

What typical certifications should a buyer request for these sealing products?

Buyers should request ISO 9001 quality‑management certification, REACH compliance documentation for PVC and rubber chemicals, and any relevant fire‑safety certificates such as UL 10B or EN 13501‑1.

What are common specifications for PVC and EPDM seals in this category?

PVC seals are often produced to GB/T 10002‑2006 with Shore A hardness of 70‑80 and thicknesses between 0.5 mm and 3 mm. EPDM seals usually meet ISO 1629, offering ozone resistance and hardness in the 60‑80 Shore A range.

What is a typical minimum order quantity and lead time for the door‑seal brush strips?

The brush strips are usually sold in batches of 500 units or more, with a lead time of roughly 30‑40 days from order confirmation, subject to material stock.

How are the products typically packaged for international shipment?

Products are packed in moisture‑resistant corrugated boxes, often bundled in sets of 100‑200 units, and loaded into 20‑ft or 40‑ft containers for sea freight.

Which regions most frequently import these types of door sealing products from China?

Key import markets include Southeast Asian construction firms, European building‑material distributors, and North American automotive interior suppliers.

What documentation should be reviewed before finalising a purchase?
