Q1: What Is the Minimum Order Quantity (MOQ)?
A: Low MOQ per specification; we encourage mixed-batch consolidated container shipments across multiple specifications. Specific quantities are confirmed based on specifications and surface treatment. Feel free to send us a list for a quote.

Q2: Do You Support Mixed Loading and Consolidated Shipments?
A: Yes. Bolts, nuts, washers, and multiple categories of fasteners can be mixed in the same container, significantly lowering the minimum order threshold per item and overall freight costs.

Q3: Are the Strength Grades Genuinely Compliant?
A: Grade 12.9, with steel stamp markings on the head, minimum tensile strength 1220 MPa; material reports / third-party test reports can be provided, and incoming material sampling inspection is supported.

Q4: Surface Treatment and Rust Prevention Capability?
A: Standard black oxide (oxidation) treatment with basic rust prevention. For sea freight exports, we recommend upgrading to zinc plating / Dacromet / thermal diffusion galvanizing to improve salt spray resistance. We can accommodate this.

Q5: What Is the Material?
A: SCM435 chrome-molybdenum alloy steel (the mainstream material for Grade 12.9 on the market), ensuring ultra-high strength and toughness; 35CrMo can be used for special requirements.

Q6: What Is the Lead Time?
A: Regular M5–M20 in-stock specifications ship within 48 hours; custom lengths / non-standard items take approximately 7–15 days, subject to order confirmation.

Q7: Do You Support Customization and Non-Standard Products?
A: Yes. Non-standard lengths, special materials (35CrMo), and special surface treatments (zinc plating / Dacromet) can all be customized.

Q8: Packaging and OEM Labeling?
A: Inner bag + outer carton standard export packaging. Neutral packaging or customer trademark OEM labeling is supported. Shipping marks can be printed on outer cartons.

Q9: What Documents Are Required for Export?
A: Commercial invoice, packing list, material / test reports can be provided; destination country certifications (Africa PVOC / COC, Middle East, etc.) can be supported.

Q10: HS Code and Tariffs?
A: We recommend classifying under 7318.15 (other screws and bolts of iron or steel), subject to final confirmation by the customs broker; we can provide declaration elements to assist.
