Landed cost is the number a mat programme lives or dies by, and it is almost never the number on the supplier invoice. Between the factory gate and your warehouse, a rolled mat passes through five cost buckets, and each one is driven by a different decision: how the mat is rolled, how the carton is loaded, which mode you book, how the goods are classified and valued, and how long the container sits at destination. Modelling those separately is the only way to see which decision is actually costing you.
Bucket one: what happens before the container moves
Origin costs sit between the factory and the vessel. Export cartoning, palletisation where the buyer wants it, inland haulage from the plant to the port, terminal handling at origin, documentation and any inspection or testing add to the base before freight is quoted. A single rolled mat packs at roughly 3.5 kg in a carton of 36 x 24 x 72 cm, so the carton is a volume item, not a weight item: a 40 ft high cube with about 76 m3 of internal space is filled by geometry long before it reaches a weight limit. Measure the pallet footprint your supplier actually uses, because 1,200 x 1,000 mm and 1,200 x 800 mm pallets change the count per floor position.
Bucket two: main freight follows roll size, not mat count
Freight is priced on volume or on weight, whichever the carrier charges. Reduce the roll diameter by a centimetre and the carton shrinks in two dimensions, which multiplies through the container. A 5 mm mat rolled tight and sleeved travels far more efficiently than the same mat loosely rolled with air inside, and vacuum-assisted rolling or a controlled mandrel diameter is often the lowest-cost engineering change available. Sea freight suits programme volume and long transit; rail works for landlocked destinations where a port transfer adds days; air is reserved for samples, launches and replenishment of a fast seller. Each mode carries a different volatility profile, so quote the assumption and the date with the rate.
Bucket three: the duty base is a valuation question
Duty is levied on a customs value, not on the freight you paid or the retail figure you plan. The customs value normally follows the transaction value of the goods, with adjustments for items such as assists, royalties and the cost of transport to the place of importation depending on the national rule set. The World Customs Organization sets out the valuation framework and the six methods applied in sequence when transaction value cannot be used. Classification runs alongside it: exercise mats are generally treated as sporting equipment, and many administrations place them in heading 9506, but a mat with a textile face or a floor-covering character can attract a different view. Ask for a written classification position before the first shipment rather than after the first assessment.
Bucket four: destination handling and the last mile
Destination charges are where forecasts usually break. Terminal handling, customs brokerage, inspection or scanning, port storage beyond the free period, chassis or trucking to the warehouse, unloading and palletising all sit here, and several of them are charged per container or per document rather than per mat. That makes them heavy on a part-loaded container and light on a full one. Floor loading versus pallet loading is the classic trade: floor loading gains roughly ten to fifteen centimetres of usable height per tier across the box, while pallets buy faster unloading and cleaner handling. Compare the two on total delivered cost, not on the unloading hour.
Bucket five: the buffer that delay consumes
Demurrage, detention, rework and stock-out cover are the fifth bucket, and they are the ones nobody puts in the model until they arrive. A container held for extra days accrues charges per box per day, and a mis-declared item can hold the whole shipment while documents are corrected. Build the buffer from the transit variability you have actually seen on the lane, plus the lead time of the slowest component, plus the days a correction usually takes. Then treat it as a real line in the landed cost instead of a rounding difference.
Documents that keep the model intact
The commercial invoice, packing list, bill of lading, certificate of origin and any test or compliance file must agree with each other down to the carton count and the description. A description that says mat on one document and exercise equipment on another is a delay waiting to happen. Keep one master data sheet per SKU with net and gross weight, carton dimensions, quantity per carton and the classification, and issue every document from it. Our team reviews the loading plan and document set for each programme through the contact page, and the specification range behind those cartons is on the product pages.
Frequently asked questions
How many mats fit in a 40 ft container?
It depends on roll diameter and carton size, not on mat area alone. With a carton near 36 x 24 x 72 cm and a 40 ft high cube of about 76 m3, the count is set by geometry and by whether you palletise; a smaller roll diameter is the fastest way to raise the count.
Does floor loading cost less than pallets?
It usually lowers the freight per mat because you recover vertical space, but it raises unloading time and handling risk. Compare both on total delivered cost, including destination labour and damage.
Which documents does a first mat import need?
Commercial invoice, packing list, bill of lading or forwarder receipt, certificate of origin where a preference is claimed, and the test or compliance file the destination requires. All must carry the same description, quantity and carton count.
Why does duty differ between two similar mats?
Classification and customs value drive it. A different surface material or construction can move the goods to another heading, and the valuation must reflect the transaction and the adjustments your administration applies.
