Export Packaging for Bulk Fasteners: Cartons, Pallets & Containers

Packaging Is Part of the Product

A bolt that arrives at your warehouse with threads burred, zinc rubbed off and labels gone is a rejected lot even if the steel underneath is perfect. Export packaging for bulk fasteners is a solved problem — but only if the buyer specifies it. This guide covers the standard options, what each costs, and the details that decide whether a container arrives as product or as scrap.

The Standard Options

Cartons on Pallets (the default)

20–25 kg double-wall export cartons, 40–60 cartons per heat-treated ISPM-15 pallet, stretch-wrapped and strapped. This is the standard for hex bolts, nuts and washers, and what you should expect unless you specify otherwise. Advantages: handles well in any warehouse, sizes can be mixed per carton line, and damage to one carton doesn’t compromise the pallet.

Jumbo Bags (FIBC)

500–1,000 kg woven polypropylene bags, usually on pallets. Common for threaded rod bundles and large-volume plain fasteners. Cheaper per ton and faster to handle with forklifts — but a single bag requires full-line handling, and mixed sizes in one bag need inner dividers. Not suitable for zinc-plated parts without an inner liner: the woven fabric rubs the coating.

Small Boxes and Retail-Ready Packs

Inner boxes of 100–500 pcs, barcoded, printed with your brand. You pay for the print run and the packing labour; worth it if the fasteners go straight to resale or store inventory.

Labeling: Specify It or Lose a Day per Pallet

Every carton and every inner pack should carry: item and standard (e.g., DIN 933 M12×50), property class, finish, quantity, net weight, PO number, and your part number if you use one. Plain “Hex Bolt” labels turn receiving into guesswork. Barcode or QR labeling is cheap at the packing line and expensive to retrofit — agree on the label format with the first order.

Protecting the Goods Inside the Container

Sea air is wet air: for voyages through humid routes, VCI (vapor corrosion inhibitor) paper or bags inside cartons and desiccant poles in the container are inexpensive insurance for zinc and plain-finish parts. Our zinc coating guide explains why white rust starts in transit, not at sea.
HDG parts: avoid ventilated cartons in direct container-wall contact; condensation on the container roof is the classic cause of wet storage stain.
Stainless: keep A2/A4 stainless physically separated from black-steel strapping and pallet nails — carbon steel contamination causes rust spots that look like the stainless itself is failing.
Load securing: pallets braced to the container front, gaps chocked, heavy pallets on the bottom — a 20-tonne shipment that shifts in a storm is a total loss.

Container Math: What Actually Fits

Container	Usable Payload	Fastener Reality
20′ GP	~21–25 t	Fills by weight — dense product like bolts maxes out the payload before the volume
40′ GP	~26–28 t	Only pays off with bulky items or mixed cargo (e.g., pallets + HDG anchors + hardware)
40′ HQ	~26–28 t	Same weight cap, extra height for high-stacked pallets

Because fasteners are dense, consolidation matters: mixing anchors, rods and hardware into one container often beats two part-loads. And who pays for what leg is a separate question — our FOB vs CIF vs DAP guide breaks down the delivery terms.

Frequently Asked Questions

Can you pack to our specification?

Yes — carton weights, inner quantities, custom labels, barcodes and pallet patterns are all configurable. The practical workflow is to agree on a packaging spec sheet with the first order; changes after production starts cost re-handling. Send your requirements through the enquiry form.

What does custom packaging add to cost?

Roughly 2–5% of goods value for printed inner boxes and branded labeling, less for barcode-only. Jumbo bags typically save 1–3% versus cartons on dense products. These are planning numbers — the real quote depends on the run.

Is ISPM-15 pallet stamping really necessary?

Yes for wood entering most customs jurisdictions (US, EU, Australia, and most developing markets that follow IPPC rules). Missing stamps are a documented cause of quarantine holds and re-export orders. Plastic or presswood pallets sidestep the issue entirely.

How are quantities verified before loading?

By the packing list against carton counts, plus a random full count of sample cartons during pre-shipment inspection — the full procedure is in our pre-shipment inspection guide.
