CaCO3 Filler Sourcing: Ontario vs Quebec Logistics

Almost all CaCO3 filler masterbatch consumed in Canada is imported, primarily from China, Vietnam and Turkey. Once a container leaves the origin port, the importer faces a fork: route via Vancouver and rail across the prairies to Toronto, route directly to Toronto through the Panama Canal and St. Lawrence, or route to Montréal through the same St. Lawrence corridor. Each route changes the landed cost by USD 600–1,800 per FCL and the door-to-door lead time by 4–12 days.

For converters concentrated in southern Ontario, Toronto-landed is usually optimal. For converters concentrated in Quebec and the Maritimes, Montréal-landed is usually optimal. The interesting cases are converters that operate plants in both provinces (or distribute to customers in both) — for them, splitting volume between the two ports often beats consolidating on one.

A 25 MT FCL of CaCO3 masterbatch from Shanghai lands at the Port of Vancouver for approximately USD 2,400 in ocean freight, then incurs USD 1,650–1,950 in CN or CP rail to Toronto Brampton intermodal, and USD 300–450 in drayage to a GTA converter — total USD 4,350–4,800 from Shanghai to a GTA converter dock.

The same container routed via Panama and the St. Lawrence to Montréal incurs approximately USD 3,200 in ocean freight (longer voyage, smaller-vessel premium) and USD 250–350 in drayage to a Montréal converter — total USD 3,450–3,550. Routing the Montréal-landed container further to Toronto by truck adds USD 1,400–1,700, making Montréal-then-Toronto economics worse than Vancouver-rail for GTA delivery.

Conversely, a Quebec converter receiving a Vancouver-rail container pays USD 4,350–4,800 (Vancouver-Toronto-rail) plus USD 1,400–1,700 (Toronto-Montréal truck) — about USD 1,600–2,250 worse than direct Montréal landing.

The economically optimal CaCO3 inventory holding for a Canadian converter is roughly 6–10 weeks of consumption, set by the dominant cost trade-off between FCL freight savings (which pushes toward larger orders held in stock longer) and working capital plus warehouse cost (which pushes toward smaller orders and faster turn). Going below 6 weeks erodes FCL economics; going above 10 weeks ties up cash that earns nothing.

For converters with multi-province operations, splitting inventory between Toronto and Montréal in proportion to local consumption shortens emergency replenishment time. Allzone Trading uses this strategy for two customers operating in both Ontario and Quebec — main stock via our Ontario logistics partner, secondary 3-week stock at a Montréal bonded warehouse — and has measured average emergency replenishment time at under 24 hours versus 3–5 days under a single-warehouse model.

Audit your CaCO3 consumption by plant and by month for the last 24 months. If more than 70 % of your annual volume is consumed at a single Ontario plant, land FCL at Toronto via Vancouver-rail. If more than 60 % is consumed in Quebec, land FCL at Montréal. If the split is closer to 50/50, run a parallel-port strategy — two smaller FCLs per year per port — and amortize the extra freight cost against shorter emergency replenishment time.
