A bundle assembled from components made in different countries carries several duty stories in one box. Landed cost for bundles means costing each component's freight and duty, then adding assembly and fulfillment, without losing the per component truth.
From the shopper's side a bundle is one product with one price. From a cost side it may be a device from one country, a case from a second, and a consumable from a third, each with its own classification, duty rate, and freight cost per unit. Pricing the bundle from a single average import cost guarantees the average is wrong for every component in it.
The first discipline is a component cost sheet that survives the bundle. Every component keeps its own landed unit cost, calculated the same way you would cost it sold alone. The bundle's cost is then a sum of real numbers, not a separate estimate invented at bundle level.
If components are imported separately and kitted domestically, each was assessed duty on its own classification at its own entry, and the bundle simply inherits those costs. If the kit is assembled abroad and imported as a set, classification may follow the set rules and one component's character can set the duty for the whole box.
That difference can be worth real money in either direction, which is why the costing model must mirror the physical flow. Brands regularly cost a bundle using set treatment while actually importing components, or the reverse, and discover at audit or at margin review that the model described a supply chain they do not run.
Freight for components arriving in different shipments and modes cannot be spread by unit count. Allocate by the same drivers used elsewhere in your landed cost work: weight or volume for ocean, chargeable weight for air, per shipment. A dense, cheap component and a light, expensive one should not split a freight bill evenly just because they share a box at the end.
Kitting is a real landed cost layer, not overhead to forget. Labor, bundle packaging, inserts, and the extra pick and quality check belong in the bundle's unit cost, along with the higher damage and return handling bundles attract. A returned bundle often cannot be resold as a bundle, and that expected loss deserves a line too.
Bundles are usually priced as a discount off the sum of parts, which is exactly why component truth matters. Run the bundle margin at the component level and look for the passenger: the imported component with high duty and freight whose full price was carrying the discount the bundle now gives away twice.
Options once you see it clearly: reprice the bundle, swap the problem component's sourcing, drop it from the bundle and sell it as an add on, or accept it as a deliberate acquisition cost with eyes open. All four are legitimate. The illegitimate option is the one most stores choose by default, which is not knowing.
Component costs move at different speeds: one supplier raises prices, one lane's freight spikes, one classification gets reviewed. A bundle cost built once at launch quietly becomes fiction. Schedule bundle cost reviews whenever any component's landed cost changes beyond a threshold you set, and version the cost sheet so margin reports can explain themselves later.
In your accounting view, keep bundle margin and component margin reconcilable. Finance should be able to start from the bundle price, walk through each component's landed cost, kitting, and fees, and land on the same gross margin the merchandising team used to price it. When those two walks disagree, the cheaper looking one is usually the wrong one.

No. Cost each component at the duty it actually bore, which depends on whether components were imported separately or the kit entered as a set. A blended rate hides the high duty component that often decides bundle margin.
By the driver that caused it, usually weight or volume per shipment and mode, not by unit count. Components in a bundle often arrive on different lanes at very different freight cost per unit.
For pricing decisions, yes. Kitting, bundle packaging, and the extra handling and returns cost bundles attract are real per unit costs. Excluding them makes bundle margin look better than the bank account will.
Whenever a component's landed cost moves beyond a set threshold, and on a regular review cycle. Component costs change at different speeds, so a launch day bundle cost goes stale quickly.
