Bolts
Carriage Bolts Exporter
We export carriage bolts worldwide, handling customs documentation, HS code classification, and FOB/CIF/CFR shipping terms end-to-end.
As an exporter, our job is the paperwork and logistics that make international trade actually work: HS code classification, commercial invoicing, certificates of origin, and container booking under your preferred Incoterm — so the product clears customs and arrives without delay.
Buyers evaluating us specifically in the exporter role are usually less concerned with manufacturing detail and more concerned with whether the shipment will clear customs smoothly and arrive on schedule — which is why documentation accuracy and Incoterm clarity matter as much here as the product specification itself.
The square neck under a carriage bolt's head is the whole point of the design: as the nut is tightened, the neck pulls itself into a matching square hole or embeds into timber, stopping the bolt from spinning even though there's nothing to hold a wrench against on top. That self-locking behavior is why carriage bolts remain the standard choice for one-person installation on decks, fences, and playground equipment, where a second wrench simply isn't practical.

Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 350,000-500,000 pieces of carriage bolts in common sizes (M8-M10). Exact quantity depends on size and length and is confirmed at quote time.
You don't need a full container to order. Hurain Engitech & Trade — the group Global Fasteners Exports operates under — regularly ships smaller, partial-container (LCL) orders of just a few pallets or boxes for buyers who don't yet need FCL volume, consolidated with other cargo to keep freight cost reasonable.

HS Code & Customs Classification
Most fasteners fall under HS Chapter 73 (articles of iron or steel) or Chapter 74/76 for brass and aluminum items — the exact 8-10 digit subheading depends on the specific product and material. We include the HS code on the commercial invoice; confirm the applicable import duty with your customs broker, since rates vary by country and trade agreement.
