Shipping veterinary and laboratory supplies between the US and Canada
· medixanimals
A parcel crossing the United States–Canada border is not a longer domestic delivery. It is a customs event, and the information that accompanies it determines whether it moves or waits.
The data that has to travel with the goods
Every line on a cross-border shipment needs, at minimum:
- A description a customs officer can act on. "Veterinary supplies" is not one. "Sterile 15 mL conical centrifuge tubes, polypropylene, 50 per pack" is.
- An HS code. The Harmonized System is an international classification; the first six digits are common across countries, and each country extends them. The code drives duty rates and whether the goods attract any additional control.
- Country of origin. Where the goods were produced — not where they were bought, and not where they were shipped from. This is the field most often filled in wrongly, because the two differ routinely for distributed products.
- Declared value and currency, per line.
- Quantity and unit, consistent with the description.
If any of these is missing, the practical outcome is a hold, a request for information and a delay measured in days rather than hours. This is why a system should refuse to create a cross-border shipment for a line that has no HS code or origin recorded, instead of shipping it and hoping.
Who pays the duties: the incoterm
The incoterm states where the seller's responsibility ends and the buyer's begins. Two are common in this trade:
- DAP (Delivered At Place). The seller delivers to the address; the buyer is responsible for import duties and taxes, which the carrier usually collects on delivery or invoices afterwards.
- DDP (Delivered Duty Paid). The seller handles and pays import duties and taxes, so the buyer receives the goods with nothing further to pay.
Neither is universally better. DDP gives the buyer a single predictable price, at the cost of the seller pricing in duty they cannot always predict exactly. DAP keeps the price clean but means an unexpected invoice can arrive after delivery. What matters is that the term is stated before the order is placed rather than discovered afterwards.
Sales tax does not disappear at the border
Importing into Canada generally brings GST into play at the border, with provincial taxes applying according to where the goods end up. Importing into the United States involves state-level sales tax rules that depend on destination. Neither is a property of the shipment; both depend on the buyer, the destination and the nature of the goods. The practical point is that a cross-border quote is incomplete until the destination is known, which is why tax appears at checkout rather than on the product page.
Temperature control and dangerous goods make the border harder
A refrigerated shipment has a transit window. A customs hold consumes that window with no regard for it. This is the argument for getting the paperwork right the first time rather than relying on speed to absorb a delay, and the argument for despatching temperature-controlled cross-border orders early in the week.
Dangerous goods add a second layer: the classification must be declared, the packaging must match it, and some modes of transport are simply unavailable. A dangerous good that is also temperature controlled has to satisfy both sets of constraints at once, and the set of workable services can get very small.
What usually causes the delay
In roughly descending order of frequency:
- Country of origin recorded as the shipping country rather than the manufacturing country.
- A description too generic to classify.
- An HS code that does not match the description.
- Value declared inconsistently between the invoice and the customs data.
- A missing certificate or permit for an item that needed one.
Four of those five are data problems, fixable before the parcel leaves, and cheaper to fix there.
