About Shandong Yutong Commercial Trading Co., Ltd. - Security Seals Supplier in China

China hosts Shandong Yutong Commercial Trading Co., Ltd., which currently lists 91 distinct security‑seal related SKUs in its catalogue. The supplier’s portfolio spans bolt seals, cable seals, plastic and metal strip seals, as well as specialised container and meter seals that fall under HS chapter 83, including codes 8309.90, 7318.24 and 8301.60. Each entry references the material composition, such as tin‑plated steel, Q235A carbon steel or ABS plastic, reflecting the typical construction of high‑security sealing products. The catalogue also includes items described as C‑TPAT compliant, indicating alignment with U.S. Customs‑Trade Partnership standards for supply‑chain security.

Product Range and Specialties of Shandong Yutong Commercial Trading Co., Ltd.

The listed catalogue contains products such as high‑security bolt seals, steel‑cable container seals, aluminium‑lead meter seals, plastic security anchor wire seals and tamper‑proof metal‑strap seals. In the global sealing market, bolt seals are often produced to ISO 23830 (metal security seals) and may be graded by tensile strength values ranging from 1 kN to 5 kN. Cable seals typically meet ISO 17712 requirements for freight‑container security, with nylon or steel cable diameters of 3 mm to 6 mm and breaking loads of 200 kg to 600 kg. Plastic seals and ABS‑housing seals are commonly evaluated for UV resistance, temperature range (‑20 °C to +80 °C) and colour‑coded tamper‑evidence. The tinplate steel used in many of the 8309.90 items is usually low‑carbon steel coated with ~0.5 µm tin to improve corrosion resistance, while Q235A steel conforms to Chinese GB 700‑2 standards for mild steel strength (≈235 MPa).

Trade and Export Information - Shandong Yutong Commercial Trading Co., Ltd.

China remains the world’s largest exporter of security seals, shipping the majority of its output via 20‑foot and 40‑foot containers to Europe, Southeast Asia and North America. HS 8309.90 covers "Other articles of iron or steel" and is the standard classification for metal strip seals and tin‑plated steel seals, while HS 7318.24 includes "Other locks" such as bolt‑type container seals, and HS 8301.60 relates to "Other locks" with plastic bodies. Importers typically request C‑TPAT compliance documentation, ISO 9001 quality‑management certificates, and material test reports (tensile strength, corrosion resistance) to satisfy customs and logistics‑operator audits. Chinese exporters frequently use FOB or CIF Incoterms, with packaging in cardboard boxes or wooden crates, and apply anti‑theft shrink‑wrap for bulk shipments.

Sourcing from Shandong Yutong Commercial Trading Co., Ltd. - Buyer Guidance

Buyers should request a product data sheet that details material grade, tensile strength, breaking load, dimensions and any compliance certificates (C‑TPAT, ISO 17712, ISO 23830). A third‑party test report confirming the seal’s resistance to cutting, pulling and temperature extremes is standard practice before placing a bulk order. Verify that the supplier can provide samples of the exact ABS‑plastic housing or tinplate steel finish required for your application, and confirm packaging specifications such as 50‑seal per 500 g bag or 200‑seal per wooden crate for container loading.

What types of security seals does Shandong Yutong Commercial Trading Co., Ltd. list in its catalogue?

The catalogue includes high‑security bolt seals, steel‑cable container seals, aluminium‑lead meter seals, plastic security anchor wire seals, tamper‑proof metal‑strap seals and ABS‑plastic padlock seals, among others.

Which HS codes are associated with the supplier’s metal‑strip and container seals?

Metal‑strip seals are classified under HS 8309.90, steel‑cable container seals under HS 7318.24, and ABS‑plastic lock assemblies under HS 8301.60.

What material standards are typical for the tin‑plated steel seals listed?

The tin‑plated steel is usually low‑carbon steel coated with approximately 0.5 µm tin, complying with Chinese GB 700‑2 for mild steel (yield strength ≈235 MPa).

Are the listed bolt seals compatible with C‑TPAT requirements?

Several bolt seal entries are described as C‑TPAT compliant, indicating they meet the U.S. Customs‑Trade Partnership for Secure Supply‑Chain standards.

What certifications should a buyer request before ordering these seals?

Buyers should request ISO 9001 quality‑management certification, any applicable ISO 17712 (container seal) or ISO 23830 (metal security seal) test reports, and material test certificates for steel or plastic components.

What are the typical packaging formats for bulk shipments of these seals?

Exporters commonly pack metal and plastic seals in cardboard boxes or wooden crates, often grouping 50 - 200 seals per box, with shrink‑wrap applied for additional tamper evidence during container loading.

Which regions most frequently import security seals from China?

Europe, Southeast Asia and North America are the primary import markets for Chinese‑origin security seals, serving logistics companies, freight forwarders and customs agencies.

How can a buyer verify the tensile strength of a steel‑based seal?

A buyer should obtain a third‑party test report that specifies the seal’s tensile strength in megapascal (MPa) and breaking load in kilograms, measured according to ISO 23830 testing procedures.
