Two SIMA Decisions and a New CITT Inquiry
CBSA posted three SIMA items in the June 6 Canada Gazette: decisions on forged grinding media, decisions on thermoformed moulded fibre tableware, and a notice of commencement for CITT inquiry NQ-2026-002 (also grinding media). If you import steel grinding media, paper-pulp disposable tableware, or file CADs with origin preference claims that sit one HS chapter away from either product, this moves your duty math.
The decisions are final determinations following earlier investigations. The inquiry notice means CITT is opening a fresh file on forged grinding media, likely injury or threat-of-injury assessment. If you're an importer of record on subject goods, expect a questionnaire. If you're an NRI filer with a Canadian resident agent handling SIMA goods, make sure your agent knows the inquiry is live.
What Forged Grinding Media Covers
Forged grinding media are steel balls and rods used in mineral processing mills. HS classification typically sits in 7325 or 7326 depending on form and finish. SIMA cases on this product class go back a decade, with China and India as the usual named sources. The current decision likely adjusts normal-value margins or clarifies country scope after a periodic review.
If you import grinding media and your CAD shows zero SIMA duty, one of three things is true: your supplier proved non-subject origin through a CBSA exclusion ruling, your goods fall outside the product definition (cast media, not forged), or your broker missed it. The third scenario triggers an AMPS penalty on the importer of record when CBSA's verification cycle catches it, plus interest on unpaid SIMA duty from the original accounting date.
SIMA margins compound. AD duty is calculated on the transaction value, then CVD (if applicable) is added, then regular MFN or preferential duty is applied to the new base, then GST. A 50% AD margin on a USD 2,000 shipment can add CAD 1,400 all-in after compounding and exchange. Miss it on the CAD and you're paying retroactive duty plus penalty.
Thermoformed Moulded Fibre Tableware
This covers disposable plates, bowls, clamshells, and trays made from paper pulp or bagasse, typically imported by foodservice distributors and e-commerce sellers. The product definition matters: if the item has a plastic or wax coating above a specified weight percentage, it may fall outside the scope. If it's purely moulded fibre, it's subject.
China and Vietnam have been named exporters in past cases. If you're importing from either country and your commercial invoice describes the goods as "compostable tableware" or "biodegradable dinnerware," pull the SIMA product definition from CBSA's SIMA registry and confirm your HS code and scope status. Misclassification here is common because suppliers use vague English descriptions and brokers rely on those descriptions instead of the technical product spec.
If your goods are subject and you've been clearing them SIMA-free, go back through your CAD history in the CARM Client Portal and count your exposure. Voluntary disclosure before CBSA flags you cuts the AMPS penalty by half. Wait for a verification letter and you're paying full freight.
What a CITT Inquiry Notice Means for Importers
CITT inquiry NQ-2026-002 is a fresh look at forged grinding media. Injury inquiries run 120 to 240 days depending on complexity. CITT sends questionnaires to importers of record, foreign exporters, and domestic producers. If you imported subject goods in the past three years, expect to receive one.
The questionnaire asks for volume, value, and sourcing detail by country and supplier. Miss the deadline or submit incomplete data and CITT makes its injury determination without your input, which usually means they rely on the domestic producer's submission. That's not where you want the evidentiary record to sit if you're the importer.
If you're an NRI and your resident agent is handling SIMA filings, make sure the agent is monitoring CITT notices and has authority to respond on your behalf. NRI compliance gaps are the most common reason importers get blindsided by CITT questionnaires six months after the fact.
How SIMA Duty Appears on the CAD
SIMA duty is a separate line on the CAD, coded as AD (anti-dumping) or CVD (countervailing duty). It's not rolled into the tariff treatment field. If your broker is filing CUSMA preference on a good that's also SIMA-subject, the preferential rate applies to the base duty, but SIMA duty still gets assessed. Preferential origin does not exempt you from SIMA.
Common mistake: importer sees "duty: $0" on the commercial invoice summary and assumes the shipment is duty-free. That summary is the broker's tariff-rate line, not the all-in duty. SIMA, GST, and excise (if applicable) are additional. If you're releasing prior to payment under an RPP bond, the full amount including SIMA comes off your bond limit and shows up on the next K84 statement.
If your RPP bond keeps hitting its ceiling and you don't import high-value goods, check whether your broker is booking SIMA correctly. We've seen bonds sized for 10% average duty get drained by 60% effective rates after SIMA compounding.
Practical Filter: Do These Decisions Touch You?
Pull your import history for HS 7325, 7326 (grinding media) and 4823 (moulded fibre tableware, though classification can vary). If you see China, India, or Vietnam as country of origin and your CAD shows zero SIMA duty, you have a compliance question. If you see those HS codes but your origin is Canada, U.S., or EU, you're likely clear, but verify the product definition, scope can hinge on manufacturing process, not just origin.
If you're not importing either product, this Gazette entry is noise. SIMA decisions are product-specific and don't set compliance precedent outside the named goods. The only spillover risk is if you import something adjacent (say, cast grinding media or coated paper tableware) and CBSA later expands the scope through a product definition ruling.
Where the June 6 Gazette Sits in the SIMA Timeline
Gazette publication is the official public notice, but the decision date precedes publication by two to four weeks. If you imported subject goods between the decision date and today, the new margins apply retroactively to the decision date, not the Gazette date. Your broker should be checking CBSA's SIMA measures table weekly, not waiting for the Gazette.
If your brokerage team isn't doing that, you're filing CADs with stale duty rates, which means underpayment and retroactive adjustment. CARM makes this easier to catch because the portal flags duty variances above a threshold, but it doesn't auto-correct, you still have to file the amendment.
CITT inquiry timelines are separate. NQ-2026-002 will run its course over the next six months. If CITT finds injury, CBSA will impose or adjust SIMA measures at the end of the inquiry. Importers who participate in the inquiry can shape the product definition and margin structure. Importers who ignore it get whatever CITT decides.
We track Gazette postings and CITT notices daily and push flags to clients importing in the affected HS ranges. If you're clearing subject goods and didn't hear about this until now, talk to us.
