The product set also contains flange and threaded brass bushings, compression fittings and worm gears, each described with alloy designations such as C36000 free‑machining brass and CuZn39Pb3 brass. Items without explicit HS codes still fall under the broader categories of bearing components and crusher spare parts. The supplier’s focus on crusher and mining equipment parts aligns with its top categories of Construction Equipment Spare Parts, Heavy Machinery and Bearing. All listed items are presented as ready‑to‑ship components for OEM and aftermarket applications.

Product Range and Specialties of Xinxiang Haishan Machinery Co., Ltd.

The catalogue emphasizes bushings and liners for cone crushers, including Precise Bronze Bush for Cone Crushers (HS 8483.30, Tin Bronze SAE 792) and Hardened Eccentric Bushing for Metso GP300 (HS 8483.30, hardened chromium steel). In the bearing segment, the company offers Copper Bronze Bushings (HS 7407.21, C52100) and Brass Bushes (HS 7407.21, C86300 series). Brass flange bushings are listed under HS 7415.29 with material grades such as C36000 free‑machining brass. Additional components include thrust bearing plates (HS 8482.10, stainless steel 316L) and crusher socket liners.

In the mining and construction equipment market, crusher bushings are typically supplied in grades meeting ISO 9001 quality management and conform to ASTM B26 for bronze alloys, with hardness values around 70‑85 HB for tin bronze and 55‑65 HB for copper‑bronze. Brass bushings for high‑wear applications often use C36000 or C86300 alloys with tensile strength 450‑550 MPa and corrosion resistance evaluated by ASTM B581. Standard dimensions range from Ø 20 mm up to Ø 300 mm, and tolerance classes are generally IT6‑IT7 for precision crusher liners. Buyers frequently request mill test reports, hardness certificates and dimensional inspection reports.

Trade and Export Information - Xinxiang Haishan Machinery Co., Ltd.

China is a leading exporter of crusher and mining components, supplying markets in Southeast Asia, the Middle East, Africa and Latin America. HS chapters 84 (machinery) and 74 (precious metals) cover the listed bushings, with customs authorities often requiring a commercial invoice, packing list and a certificate of origin for tariff classification. Importers usually ask for ISO 9001 or CE conformity declarations, especially when the equipment will be installed in regulated sectors such as mining or construction.

Typical shipment formats include wooden crates or bulk bags loaded in 20‑ft or 40‑ft containers, with weight per container ranging from 15 t to 22 t depending on alloy density. Common Incoterms are FOB Xinxiang port or CIF destination port, allowing buyers to manage freight and insurance. Chinese export regulations mandate compliance with RoHS for copper and brass items, and anti‑dumping duties may apply in certain jurisdictions, so buyers should verify the applicable tariff rates before order placement.

Sourcing from Xinxiang Haishan Machinery Co., Ltd. - Buyer Guidance

When sourcing bushings from this supplier, buyers should request a mill test certificate (MTC) that confirms chemical composition, hardness (HB or HRB) and compliance with the specified alloy grade. Dimensional drawings with tolerance notes (e.g., IT6) and a 3‑D CAD file are useful for verifying fit in existing crusher housings.

It is advisable to verify that the supplier can provide ISO 9001 or equivalent quality management documentation, as well as any required export licences for stainless steel or high‑alloy brass. Samples of critical dimensions can be ordered before full production, and MOQ typically starts at one full container load, with lead times of 30‑45 days from order confirmation.

What types of crusher bushings are listed by Xinxiang Haishan Machinery?

The catalogue includes tin‑bronze bushings for cone crushers (HS 8483.30), copper‑bronze bushings (HS 7407.21), hardened chromium‑steel eccentric bushings (HS 8483.30) and stainless‑steel thrust bearing plates (HS 8482.10). All items are designed for PYB‑900 and similar cone crusher models.

Which HS codes apply to the brass flange bushings in the catalogue?

Brass flange and threaded bushings are classified under HS 7415.29, while other brass components such as compression fittings fall under HS 7407.21. The codes correspond to articles of brass, copper and other non‑ferrous metals.

What material standards should a buyer verify for the bronze bushings?

Buyers should check that the bronze alloys meet ASTM B26 (tin bronze) or ASTM B535 (copper‑bronze) specifications, with typical chemical limits for Cu, Sn, Zn and Pb as listed in the product description. Hardness and tensile strength values are usually provided in the mill test report.

Are there typical minimum order quantities for these components?

For most bushing types the supplier ships in full container loads, which translates to roughly 15 tons for bronze or brass items. Smaller quantities may be arranged as sample kits, but standard orders start at one 20‑ft container.

What lead time is common for the listed crusher spare parts?

Production and machining of precision bushings generally require 30‑45 days from receipt of a confirmed purchase order and approved material certificates. Additional time may be needed for custom dimensions or special alloy requests.

Which certifications are commonly required for importing these parts?

Importers usually request ISO 9001 quality management certification, a mill test certificate, and, where applicable, CE marking or RoHS compliance for copper and brass items. A certificate of origin is also standard for customs clearance.

How are the bushings typically packaged for export?

Items are packed in wooden crates with internal cushioning, or in bulk bags for larger volumes, to protect against impact and corrosion. Packaging is designed to fit standard 20‑ft or 40‑ft containers and includes moisture‑resistant liners for stainless‑steel components.
