Which heavy machinery brands are your exhaust pipes and corrugated hoses compatible with?

Accepted Answer

We supply parts compatible with SANY, Zoomlion, XCMG, Caterpillar, Komatsu, Volvo, LiuGong, and other mainstream brands across excavators, loaders, cranes, and rollers. Compatibility is confirmed by your equipment model, serial number, or product specifications. We also support custom orders based on your drawings or sample parts.

Question 2

Question 3

What are your products' materials, temperature, and pressure ratings?

Accepted Answer

Core materials are 304/316 stainless steel and heat-resistant carbon steel. Our corrugated hose uses multi-layer stainless bellows with braided mesh shielding. Operating temperature range: -40°C to 800°C. Pressure rating: up to 1.6 MPa. Exhaust pipes receive high-temperature anti-corrosion treatment with service life ≥ 8,000 hours.

Question 4

What is your minimum order quantity (MOQ)?

Accepted Answer

Standard products: MOQ 10 pieces. Custom products: MOQ 5 pieces. For initial international customers, we can negotiate down to 3 pieces (with a small additional production-cost share) to support small trial orders for quality verification.

Question 5

What are your production and delivery lead times?

Accepted Answer

Standard products: 3–7 days production. Custom products: 7–25 days depending on complexity. International logistics supports sea freight (FOB/CIF), air/express (DDU). DDP service available for Southeast Asia and Russia. Transit time 3–30 days.

Question 6

Are your products internationally certified?

Accepted Answer

All products follow ISO 9001:2015 and IATF 16949:2016 quality management systems. Every batch comes with material inspection reports and pressure/temperature test reports. For region-specific certifications (EU CE, North American DOT), we offer targeted certification services (15–30 days).

Question 7

Which payment methods do you accept?

Accepted Answer

T/T (telegraphic transfer), L/C (sight letter of credit), and Western Union are all supported. For initial cooperation we use a '30% deposit + 70% balance against bill of lading copy' model — balance due within 7 days of B/L copy receipt.

Question 8

Do you offer overseas after-sales service?

Accepted Answer

Yes. 12-month warranty covers material cracking and performance failures not caused by human factors. During warranty: free replacement (customer pays round-trip freight) or discounted resupply. 24/7 online technical support is available.

Question 9

Can you provide all required export documentation?

Accepted Answer

Yes — commercial invoices, packing lists, bills of lading, certificates of origin (CO/FTA), customs declarations, and product inspection reports. Documents formatted to your destination country's specific requirements.

Question 10

Do you offer custom (non-standard) sizes?

Accepted Answer

Yes. Our R&D team customizes based on your drawings, samples, or specifications (length, diameter, connector type, working environment). Standard customization (size or connector adjustments) takes 7–15 days. Complex customization (material substitution or structural optimization) takes 15–25 days. Detailed timelines are provided before order confirmation. Samples can be produced before mass production.

Question 11

How do you ensure batch consistency with the approved sample?

Accepted Answer

Mass production follows a "triple inspection" system: incoming material inspection, in-process inspection, and final inspection. Critical processes are controlled by technicians with 5+ years experience. Batch products use the same materials, processes, and inspection standards as the approved sample. We provide in-process inspection videos on request.

Question 12

How do I get a quote or sample?

Accepted Answer

Provide your equipment model, product specifications, or drawings — we'll quote precisely. Standard samples are free (freight collect). Custom samples may require a small tooling fee, which is refunded against the bulk order.

Question 13

Does export packaging include branding? Can you do private label?

Accepted Answer

Standard packaging: export-grade cartons with foam protection (prevents transit damage). Labeling includes Maxcorro brand, product model, material, production date, and compliance markings (required for customs clearance — no-brand shipments cannot pass customs). We support customer-branded labels with your trademark authorization document and compliant artwork (we'll assist with destination-country labeling-rule review).

Question 14

Do your products meet our local environmental and safety standards?

Accepted Answer

Products contain no heavy metals or hazardous substances and meet RoHS and REACH standards. We provide region-specific compliance testing support (EU, North America, Southeast Asia) to help you complete local market entry reviews.

Question 15

How do small-batch trial orders differ from bulk-order pricing?

Accepted Answer

Trial orders (3–5 pieces): cost price + small service fee. Bulk orders (≥10 pieces): tiered discounts — 5% off for 10–50 pieces, 10% off for 50+ pieces. Bulk orders placed within 3 months of trial-order approval refund the trial-order service fee.
